Inverting Images for Uninvited Users
Several readers offered comments on the methods of network interference suggested in the examples linked from the story, or offered other creative ways to impede network freeloaders. First, reader blantonl offers some insight into implementing the same image-flipping technique:
For those that are struggling to understand how the author of this article is accomplishing his approach, here is some further information.
The author obviously has a Linux server in his house, that is running DHCPD
To selectively send some clients to some locations, and others to the normal internet, he assigns an IP address on a different network to clients that don't have MAC Addresses that he knows about.
Forwarding on to sites of his choice is done by using IPTables, which is a utility that allows you to configure the packet filtering components of the Linux TCP/IP Stack. In this instance, the Linux box is just functioning as a firewall, and he is selectively sending requests from certain IP addresses to different hosts of his choosing.
Finally, the Up-side-down and blurry-image conversions is accomplished by sending page requests from those before-mentioned IP addresses to a proxy server, which in this case is Squid — and then allowing the proxy server to run a script which calls an ImageMagick command called mogrify which allows you to resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.
(Writing "I'm paranoid - I work in information security," reader hab136 points out some potential vulnerabilities in the system as described.)
As to the actual methods of annoyance, jpellino writes
Upside down is cute, but blurry is just too fantastic. You know they were on the horn to the vendor after punching every monitor control and several loud screaming matches and an expensive service call for a monitor that then worked just fine on the bench... As a webmaster I can now say April 1 just got very far away...
Reader Sloppy also admires the "blurry-net" approach ("That's subtle and I love it"), but suggests that image manipulation is only for starters
And perhaps the ultimate in annoyance-as-warning, reader Midnight Thunder writesThe next step is to spy on them and see what websites they visit, and then insert some fake content one day. For example, if they use it to read CNN, insert a casual story about a nuclear weapon getting used in the Middle-East or South Asia, or a story about the president of USA selecting a new vice-president due to the assassination last week ("What?! I didn't hear about that!"), or the CDC in Atlanta is investigating the recent rash of improbable claims about the dead returning to life to feast on the flesh of the living, etc. If they visit Slashdot, then the jig is probably up, but maybe it would be great to have a story where a security study found Windows98 to kick OpenBSD's ass and then a bunch of comments where everyone agrees that the findings pretty much match their own experience, along with complains about "how is this news for nerds?!"
Not all uninvited users are actually unwanted users, though, at least for some readers. Reader Elektroschock writesI suppose you could also add a frame to every page and then sell advertising space. Since you probably know a bit about your neighbour it is much easier make targeted advertising. Of course you could always make the top frame read:
"This is borrowed bandwidth. Have you thought about getting your own connection."
Oh and make sure it is flashing. Actually you could make it so that the whole content flash.
Similarly, trewornan writesSorry, I am a supporter of open networks. I think the freifunk olsr-protocol approach of open wireless networks is best. We don't need internet providers and we don't need internet providers which leak our communication data to the governments and endanger the freedom of the net. The net should be a net and wireless technology is great for the creation of a real P2P internet.
I cannot support any action against people who use your network. It is against my understanding of hacker ethics. When you don't like it then close your network. But no childish games please.
I may even say that I find it unethical to exclude your neighbours from using your network but I respect your opinions. When your network is open it means: Be free to use it. Not: You can use it but I will fuck up or intercept your communication.
I chose to leave my wireless network open so that if someone nearby needed a connection it would be available for them. If someone was to impose an unreasonable load on the network I might do something about it but so far (12 months) I've had about half a dozen people connect and download relatively small amounts of data - my guess is they were checking email. Why would I object to that? No . . . why would *you* object to that? The way I see it it's a chance to do something nice for other people, why not get yourself some good karma.
Even without that sort of altruism, many readers feel that, as geekoid puts it,
Not so fast, goes an argument exemplified in another comment from R2.0:[By]leaving it open he is inviting other people to connect.
Some computer says to the router "Hey, can I come in?" and the router says "Sure." Now, the moment you put something up, like needing a password, then you are no longer inviting people in.
- Computer says "Hey, can I come in" router says "Sure, if you know the password."
- Or you can encrypt it; Computer says "Hey, can I come in?" the router says "KE*jd7638JDEJE*834899(&^&#nd&#&bd*e#"
Yes, the computer is "asking" the router "permission," and the router is "granting permission" — the only problem is, the words we use to describe these actions may appear to be descriptive of thinking and volition, but they really mean neither. Computers and routers simply CANNOT give "permission" in any legal or moral sense.
To use the yard analogy that seems to be popular for these threads, lets supposed your neighbor's massively retarded child asks your massively retarded child for permission for his Daddy to use your yard, and your child agrees. Neighbor then comes over and stages a cookout on your lawn, or for that matter just walks across it.
When you confront him, he says "But my kid asked your kid, and he said yes." This is binding? Common sense and the law would say no, yet you would allow devices with an order of magnitude less analytical power than a retarded child to give and receive similar permissions.
Repeat after me folks: devices cannot give and receive permission for human actions without those permissions expressly being granted via some other means.
A traffic light doesn't give you permission to cross the street; the government (that you studied to get your license) gives you permission to cross the intersection when a light is green, and denies it when red.
Your ID badge doesn't ask permission to enter your building, and the security system doesn't grant permission; YOU ask for permission by presenting the badge, and your employer grants it by programming said system to accept your request.
Closer to the typical small-time network admin, perhaps, bennomatic writes
Various forms of the same disagreement surfaced in various corners of the discussion: squiggleslash, for instance, writesIf I leave my bike outside unlocked for 10 minutes, am I giving explicit permission to anyone who sees it that they can take it? No. Am I allowing it to happen through negligence? Sure, but call it what it is; it's still stealing, or at least trespassing.
Even something as amorphous as bandwidth is a limited resource. To paraphrase the head of the commerce committee, an open wireless connection is not a dump truck you can just load up with as much as you like; it's a tube!
The figurative "visibility" of an open wireless network also isn't enough to convince reader R2.0 that it's fair game for passers by. He writes:[I]t makes sense that no implied permission is given by simply having your router be unsecured, given "unsecured" is the default configuration of most off-the-shelf routers.)
It really isn't an issue in practice. If you want to use someone else's network, all you have to do is ask them. With 802.11, you're close enough to be able to do so. There's no reason not to ask, other than knowing that "No" is likely to be the answer. And I think that's why people tell themselves the myth that somehow they have implied permission simply because the "door" was left unlocked.
So the router is "visible," with an option to make it invisible. Big deal. My garden is visible from the street, but I can put a tarp around it to obscure its existence. What you are saying is that, unless I put a tarp up around my garden, everyone has a right to use it.
Wireless networks may make themselves conspicuous, but that does not confer an invitation to use them. The connection between "visible" and "inviting" is not legally or morally valid. (I am excepting the concept of "attractive nuisance," but I don't think open routers will come under that area of liability)
Reader 4e617474 fired the next volley in this battle of analogies:
No, actually we're saying that if your garden pelts us with carrots and peas as we walk past on the public street, we're at liberty to catch them and consume them. Only if you place anti-vegetable-flight netting around your garden (or stop planting vegetables that lend themselves to comparison to an unsecured WAP) does it become incumbent upon us to behave as good citizens.
Hey! Analogies are fun! Somebody compare Internet privacy law to hunting and fishing licenses!
Readers like ShawnDoc make a case persuasive for discouraging bandwidth borrowing on the basis of enlightened self-interest.
If someone uses your connection for illegal activity (downloading Meet the Fockers, kiddie porn) it will be your IP address that the RIAA/MPAA/FBI will trace. Good luck convincing them it wasn't you. You might be able to do it, but it will take up time and money (lawyers) to clear your name. And in the case of kiddie porn or other criminal act, expect every computer, PDA, and cell phone in your home to be confiscated to be analyzed for incriminating data. The second problem is you are allowing strangers access to not only your Internet connection, but also your LAN. I have multiple computers and put files in shared folders so I can access them from different machines. I don't want some strange to have access to those files, or worse, have their computer be infected with a worm/virus that propagates across the network.
Thanks to all the readers whose comments informed this conversation, and in particular to those whose comments are quoted above.
To use the yard analogy that seems to be popular for these threads, lets supposed your neighbor's massively retarded child asks your massively retarded child for permission for his Daddy to use your yard, and your child agrees. Neighbor then comes over and stages a cookout on your lawn, or for that matter just walks across it.
This is a very interesting anology, as computer systems are very "dumb," but unlike developmentally challenged individuals, computers are also very easy to control (i.e. they do precisely what you tell them to and nothing else, if you count the code as instructions). It is a simple matter to encrypt a wifi point (and a well reccomended practice), whereas a retarded child is probably difficult to train to restrict lawn access, and that is not generally a well-reccomended practice.
To be honest, I don't think any analogy quite sums up the situation. If you're on someone's wifi, and you're not causing harm, and they left it open, what is the problem?
There simply isn't an adequate analogy for this situation, as nothing else is like an unsecured access point. Please stop comparing them as such.
Hey, can I bum a sig?
All of the locked door, stolen bike, and lawn analogies miss one important fact. 802.11 uses the radio spectrum. In the US we ALL own the radio spectrum, but "trust" the FCC to manage it.
The FCC says you can transmit on that band within X power. They also say if a a signal enters your reciever you can read it.
Together they imply you can join an unsecured network, because that person is allowing their equipment to broadcast, and recieve on open frequencies.
There is a lot of nasty stuff that you can do if you are routing the traffic through a squid proxy like the author of the original article did. Imagine replacing all images with Goatse.cx or redirecting all web traffic to a page announcing "You are a bandwidth thief!".
The more serious and disturbing outcome of this story is in that it presents a case for how wardrivers can have their passwords and personal information stolen through a clever phishing attack using a proxy. You can argue they deserve it for piggybacking on others' bandwidth but the potential for exploitation here is huge (imagine if somebody put an open access point near Central Park).

Slashdot is not about stories, Digg and other linkfarms are about stories. Slashdot is about comments, Slashdot is about community. Considering the sorry state of the moderation system, it's hard to read many of the good comments without also coming upon highly-rated but rather banal comments (including a few I have authored). People who are too busy to browse through hundreds of comments will enjoy the backslash approach, and I, for one, think it can help extend debate on issues that are important (at least for nerds).
I spent the whole yesterday refreshing the slashdot frontpage, and somehow managed to miss the story!

OK, so how exactly are you connecting to Slashdot without using an ISP? Are you standing at a terminal in the cage at SAVVIS where Slashdot's servers are located?
sarchasm: The gulf between the author of sarcastic wit and the person who doesn't get it.
There's something about Slashdot that encourages these terrible analogies, and it's just awful to watch. Sometimes, I see a story, and I can tell beforehand that there's going to be a bunch of these crappy analogies being thrown around, argued over and refined. It's usually around then that I turn my computer off and go outside, so in a sense, they literally send me running.
So when my PPPoE connection goes U with my ISP (I have ADSL) I am asking permission to connect, but, I have no permission to use the connection, since computers and routers cannot give permission, right?
When I check my mail, I ask permission via POP3 but, I don't have permission, since a computer cannot give permission...
Your argument doesn't seem to work.

If so, then you're giving your neighbors cancer and they're entitled to take some of your bandwidth as retribution / reparations. Do not mod this funny.
Having an unsecured wireless network provides plausible deniability for p2p downloading and what-not. Unless of course you live in Wyoming and have no neighbors for miles.
The second problem is you are allowing strangers access to not only your Internet connection, but also your LAN. I have multiple computers and put files in shared folders so I can access them from different machines.

I recently got a Nintendo DS and decided to set up a wireless network so I could play online with it. I have never previously needed a wireless network in my home, prefering the security of wire-bound communications. Since most of my computers are desktops that hopefully have little mobility, I can just drop a wire and forget about it.
My concern was the same, especially because the DS only supports WEP, meaning I should probably assume my network to be compromised. But then I found a better way to use my current security (NAT routing only ports where I'm expecting communications) to extend the network. Basically, take the existing network, showing only those ports you've opened to the public Internet on a common IP address, and move them back behind a second NAT router (the new wireless router). Set the first NAT router on the second NAT router's DMZ. Set the first NAT router's gateway to the IP address of the second NAT router (as seen by the first NAT router). Now, any wireless clients connecting to the second NAT router/access point will still be able to see the rest of your network, but only through the single IP address of the first NAT router, and only through those ports you would have opened anyway.
Sure, someone can still use your bandwidth, but at least you can add another layer of protection to your sensitive machines.

I am consistently amazed at how many people bitch about this. Get over it. I can't read every article, and I appreciate these recaps. If you don't, fine; just shut the hell up about it. No one's got a gun to your head to force you to read the backslash posts.
The idea is this:
:)
Many people never read what may be some of the best comments because a particular story has gone quite a ways down the page by the time they see it. And some of the "best" comments (obviously there's some subjectivity to it) are ones that may not be as highly moderated as some decent ones which happen to have been made earlier and therefore had more time to be moderated up. (Also, some comments might be less interesting alone, but are catalyzed by the presence of surrounding ones.)
So we try to cherrypick some of the ones which would give a reader who'd glanced at (or even hadn't glanced at) the original story a sense of the reaction it inspired, without needing to dig through quite as many pages of comments.
You know, while I'd rather you enjoyed it, it's also easy to avoid (for any logged-in user) by adjusting preferences. Some people do; for any large-scale information feeds (or even medium-scale, like Slashdot), everyone filters *somehow,* whether by glancing past topics they don't like, or by using the provided filtering tools (including moderation threshold and section exclusion). It's not my intent to annoy you

I happen to like backslash, gives me a change to read some of the comments I missed the first time I read through it.
I'm amazed at the amount of people insisting that an open wireless router is an implicit invitation to join, and the number of people saying "if you are doing no harm, what's the problem?"
I love the idealistic vision of information being free, of internet access being free, etc - but the "hacker ethic" is no excuse for stealing.
Problem 1: Your average person is not very tech savvy, so your average internet router comes unsecured so that it works straight out of the box for your average version. This means that the vast majority of wireless routers are open unintentionally by people who don't read instructions or know anything about security. And why read the instructions if they don't have to? If it works right out of the box, why spend time reading the damn booklet? This means that the majority of unsecured wireless connections are likely that way because people don't know any better, not because they're Just Like You(tm) and want to share.
Problem 2: Even if these people left them open for convenience, sharing, etc - their terms of service with their ISP almost always have a clause saying that service is to be used only be residents of the billing address. By using their connection, whether they want you to or not, you are aiding them in breaking their TOS.
Problem 3: No, seriously, get it through your thick skull - that network isn't open because the guy who owns it reads slashdot and agrees with you. It's open because the guy doesn't know any better. However, his "stupidity" (reality: lack of interest in technology to the degree of yours) does not give you the "right" to steal.
Problem 4: You can say "if it doesn't hurt his bandwidth usage, it's fine", but that becomes a slippery slope. How many people get to borrow Unsuspecting Bob's internet connection then?
Problem 5: If you were to win the argument that people should be free to share their connections with the world, you would kill ISPs as a business. It's tantamount to arguing that it should be perfectly legal for one guy at the top of an apartment building to pay for cable internet, and for every resident of that building to mod a Linksys router and get the whole building on a WDS mesh through one connection. I'm no fan of the cable company, believe me, but doing this is still not fair to business.

Suppose that you redirect all content requests to an illegal download that is not stored on anything that is associated with you. Who then would be legally at fault? You're doing nothing illegal, its your routing equipment, you can do with it what you damn well please. Is the freeloader suddenly guilty of breaking whatever laws the download or its contents violate?

What bugs me about this is how some people spend time writing up bitingly barbed and highly satirical screeds about the monumental stupidity of common users. "Imagine this bozo trying to set up a home network like he was a real sysadmin," they sneer. "And the whole time he doesn't realize that the brand of router he's using has a vulnerability somewhere deep in the firmware. If I'd been him, I'd have spent more money and more time, but instead this poor sap gets to deal with what his ignorance has unleashed...." and so on, ad nauseam.
The reason it annoys me is because, when these people are caught piggybacking onto their next-door neighbor's wireless, they then post that "this whole debate is silly, anyway, because the airwaves are free to everybody, and it's unfair to expect someone not to take advantage of such an unexpected bounty, and anyway the neighbor wasn't using that much of it in the first place, and he had it coming for not securing his network...."
But then again, I guess that's different.

You don't want anyone using your wireless network, yet you want to leave it open? I have the perfect solution for you! Enclose your property in a Faraday Cage, and be done with it. Quit griping, quit saying "If this, if that, balh, blah, blah," and DO SOMETHING. Either drop some serious money on having your connection and network set up how you want it and secured how you want it, or don't complain and gripe when someone else accesses your shit. - PERIOD.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
the bottom line is that the router invites people to connect. That is what it does, that's it's purpose that is why it was designed.
As for his retard analogy, that was just in poor taste; however as soon as the owner of the property came over and told the other people to leave then they would be obligated to do so.

I live in Austin. There are hundreds of businesses here with free WiFi. The city has free WiFi blanketing downtown. This isn't really a trespass issue. How exactly do you know which networks are free to use without using encryption as a clue? If anything the issue of trespass is only an issue because WiFi is public in much the same way as a large green space and includes no way to provide a "No Trespassing" sign.
We are consumers buying products that are pre-configured as a "house party connection". Why don't they come disabled, so the user HAS to go into the config, and apply his personal approval to the routers setup.
So, if it's enabled at all, you know some liability/judgement was applied.

Btw, pro "open access" folks would say that ISP's got their monopolies on providing net access via fraud (direct or indirect) etc. and therefore it's moral to not abide by their TOS.
Some would say it should be allowed that people can share their connection with others if they choose. "This is the electronic equivalent of allowing someone to browse the net on my PC at home. Who's biz is it where they are? What's next auto makers restricting who a person can lend my car to?"
Others wish there was a legal allowed wifi name/key etc. that basically means the owner is saying "here's a "secure" wifi for others to authenticate with and use".
I'm not taking a position
6. If you're in a non-poor neighborhood, there are going to be several wireless nets in range of any given spot. Even if Bob Niceguy decides to share his bandwidth and tells his friends it's okay, they might not know which access point is his, and just link up to any random place. ...and if you're living right next to (for example) a coffee shop, you could get a dozen random freeloaders on at any given time who all think it's okay, since the "free wireless" sign is right there for all to see.

I've tackled this problem at my house by setting up a captive portal and Radius-based MAC authentication. Basically, the captive portal tells them they aren't registered, then they register with their name and how long they want access for. It'll automatically grant them access, and it will email me right away. If I have no idea who it is, I can log in and disable their access to the Internet and prevent them from getting an IP address from my DHCP server, all from a convenient web interface I wrote. I also have a packet filter in place that disables people if they try to use any form of P2P, unless specifically allowed. This way I can leave the access points totally open, and if someone misbehaves, I simply hit the disable button, and they're completely offline one minute later.

So if the connection is open, that implies that the OWNER of the connection doesn't mind that you connect.
Just like advertising you are having a garages sale implies you are inviting people over to look through your stuff. Of course barriers are set up so you don't wander into lother areas. If not a physical barrier, then certianl; a social barrier.
No such social berriers exist with a computer, so you need a physical barries, like asking for log in.
Now if someone goes around your barrier, then it is 'wrong'.

WTF is with all these property analogies?

Doesn't anyone remember that copyright infringement != theft?
:(){
The parent anonymous coward had an excellent point -- the FCC rules under which your wireless access point operates include a clause that you (the owner of the access point) must accept any interference, even interference that causes undesired operation. To my mind, that includes interference that causes child-porn to be downloaded. (After all, that certainly counts as "undesired operation" of the router for most people).
In short, owner/operator beware -- whatever EM radiation hits your router, it's your problem. If you don't intend your network to be shared, you must take active measures to prevent that.
The more serious and disturbing outcome of this story is in that it presents a case for how wardrivers can have their passwords and personal information stolen through a clever phishing attack using a proxy.
What's preventing a guy from parking his van outside a Starbucks in a well to do neighborhood and having his his SSID say "Starbucks Free Wirless" and wait for people to connect and log all their actions through a proxy server.

We have a (desktop) computer on the far side of the house, so I set up a wireless link to it. Unfortuately, that link sometimes associates with the neighbor's (open) base station.
It would be nice if I could figure how how to instruct windows not to join any networks but my own, but I haven't seen an obvious way to do this under XP. Any suggestions appreciated!
If you could guarantee you were only using bandwith that would otherwise go unused. However, in the router case, connecting to the network results in the owner having less "water" to use on his own lawn.

I.e., the network is "open" in the 802.11 sense, but isn't "open" in the sense that he wants people to be able to happily surf normally using his connection, or in the sense that you can expect your traffic through the network to be unmolested at any protocol level. Think of it, if you will, as a form of encryption. Yes, you can choose to view the act of not securing a network at the 802.11 level as an invitation to use the network as you please without any obligation on your part either to compensate the person providing the network or to provide a network others can use. You can also choose to view the act of not locking a bicycle as an invitation to use it as you please without any obligation to return it when you're done, compensate the person providing the bicycle, or provide a bicycle that others can use, but, if you do, in neither case would I take your moral views on that subject very seriously, and I suspect most other people - including, perhaps, even fans of free networks or bicycle-sharing programs - would do so, as moral views of that sort leave some people free of moral constraints on the issue in question.)
Electroschock's speaking of "P2P" in this context was also a bit off; he said "The net should be a net and wireless technology is great for the creation of a real P2P internet." "P" in "P2P" stands for "peer"; unless your neighbors are letting you use their wireless network, what's going on isn't peer-to-peer, it's somebody deciding that they're entitled to your bandwidth but they don't have to provide any bandwidth of their own.
In an ISP-less world of free networks, I think it'd be inappropriate to muck with the network access of people whose packets happen to be traversing your network if it's part of a free (inter)network. That's not a world people use ISPs to route their packets to the rest of the Intarweb, and in which some people use other people's ISP connections to route their packets to the rest of the Intarweb, however, and that's the world the prankster is speaking of.
I want to try my hand... Let say that the bandwidth is like a hose. You rent one piece and you buy another, which are your connection to the internet, and your personal router. You take this hose and hook it up to a public waterline (the internet). You then leave the other end out on the street. I don't think their is a court in country that would convict you for taking a drink from that hose. I don't think that there are even many people that would say it was even rude to take a drink from that hose.
Now, if you put a sign up that said. "Please don't drink from my hose. It is for private use only.", SOME people might consider it rude to drink from it, but I doubt that you would find a court that would convict over it.
If you put a lock on the end of that hose, and someone came along and picked that lock to drink from your hose, you probably could find a court that would convict, and most people would see a problem with that.
If someone found out that if they blew three times into the hose, it would turn a nozzel, and start drawing water out of your personal water tank that is used to supply your house, and they proceded to drain your tank, or harm it in any way, everyone would see that as a problem, and most assuradly a court would convict.
Of course while the court would convict, and everyone would agree that that person was wrong in what they did, you would also get lambasted over how much of an idiot you were for not putting a lock on the end of a hose that is both connect to your personal water tank and has an end out on the street where anyone can access it.
We'd all like to see that "convenient web interface".

Don't worry, you won't shock me, I've written
You hit the nail on the head. I think people too often overlook their OWN RESPONSIBILITY when they turn on their WIFI.
A slightly off thought I wanted to get out is that people often try to take your approach to unsecured servers. They figure that if the server is insecure and they get into then, as long as they don't harm anything, they are fully justified. There is a big difference between receiving/using transmissions that FEDERAL LAW ALLOWS US TO and purposefully (often forcibly) getting into someone else's server. Sorry for the analogy but, it is the same difference between picking up your neighbor's signal and entering their house (uninvited) to plug in an ethernet cable into their router.
Faith is a willingness to accept something w/o complete proof and to act on it. Reason allows you to correct that faith.
Have I already lost?
As I mentioned yesterday (but apparantly wasn't cool enough to get included in the back slash), it is entirely within the realm of possibility that the neighbor in question just didn't realize they were using someone else's wireless connection. They very likely could have gone to best buy, bought a wireless 'kit' hooked up the WAP, installed their wireless card, which happily connected to the first wireless network it detected, the unsecured wireless connection next door. I know that even though I have the wireless card in my laptop set to automatically connect to "known" connections first, I have found myself accidentally connected to my neighbors wireless, with the only indication given to me was that my signal strength was WAY less than it should be. If I hadn't noticed that, there's no telling how long I would have been using my neighbors wireless.
IANAL... But I play one on
There are those who make the argument that the signal goes onto their property and, therefore, they can use it. As I understand it, if the neighbor's fruit tree drops fruit in your yard, it's yours. In fact, if the branches of the fruit tree are over your property, you can grab the fruit off the part of the tree that crosses onto your property. So there's some reasonable basis for that.
However, I would argue the right goes both ways. You have every right to do whatever you want with the packets I am throwing into your yard. I, in turn, have every right to do what I want with the packets you throw back into my yard. If I want to ignore them, accept them, or fiddle with them before sending them through, that's fine. After all, once those packets entered my property, they became mine to do with as I wish, right? Just like the packets I sent onto your property were yours. Turn about is fair play.
Personally, I thought the idea was great. I'd've been far crueler, though, and changed out every picture with goatse.cx or tubgirl. Which brings up an entertaining question...
Suppose I redirect every web request to a website with pornographic pictures. Suppose the neighbor's kids try to go to disney.com and, instead, get smutsite.com. Can I be arrested for distributing pornography to minors?
A better analogy, I think: If you have a cordless house phone, connected to your home line, on the footpath/sidewalk outside your house (I suppose it's chained to your fence or something as well). You sometimes use it there, and when people pass by they sometimes use it. The phone has the capacity to be locked to a certain password before it can be used, but you have chosen not to activate this because you are a good samaritan. In this scenario, someone has been coming along and calling china, parts of europe, and new zealand on the phone, and you don't like that -- so rather than putting a password on the phone so noone can use it, the homeowner has decided all the international calls are going to be rerouted to 1-800-KITTENS, ensuring both security and hilarity! It's the same as putting a password on the phone, but funnier because the person who's been abusing the priviledge is placed in a very confusing scenario. Lighten up, nerds!
When walking around in Brooklyn one will often come across a box of books in front a residence. It's generally assumed that these are free for the taking. Sometimes it will be a nice sunny summer afternoon and there will be just one book laying in front of the building.
Most routers use the 192.168.0.*, 192.168.1.*, 192.168.2.*, or 10.0.0.* ranges by default. It isn't hard to set a static IP with the gateway and DNS (most routers proxy DNS) set to 192.168.0.1 or whatever. Even if you're not granted a DHCP lease, you can still get access pretty easily sometimes.

I like slashdot a lot, but I like it less every time I see a backslash article. Even the name sounds like an unimaginative rehash of "slashback".
I HATE IT
I HAT?E IIT I HATE IT.
I'm not being a troll, I'm voicing my heartfelt opinion that this feature/section is an abomination and it makes my blood boil. AAHHH.
It must take less time to just pull another story out of the mail bag than to compile this bullshit, so why bother?
Honestly, ENOUGH!
Also, I know "If I don't like it, I don't have to read it", but I don't even notice which section a story is in half the time. I just read
the summary. Reading the section name first for each one just to avoid this section is a big waste of my time that I should be
doing something productive at work. After two sentences I'm like "Hmm... why am I reading a poorly written, poorly analyzed
summary of some obviously inconsequential, illinformed discussion? AH! BACKSLASH!" It's the Goatse of slashdot.org, really.
<strike></rant></strike> I'M STILL MAD.
As a practicing dumpster diver, this is a topic well familiar to me. Fact is, playing little juvenile mind-games with someone who is probably just using your network connection to check their e-mail is no better than deliberately snapping a load of DVDs before discarding them, or kniving up boxes of food. It's the kind of childishness by which whenever another kid wants to borrow one of your toys, it proves itself the one that you were 'just about to play with'. An unsecure connection is no different than a Wireless Dumpster. Because by not employing so much as a password, you have openly shown a disregard for its 'theft' tantamount to discardation.
Once encrypted or passworded, though, your wireless morsels are shelved all snug indoors, and to use them is inarguably theft. But as long as your actions keep screaming 'Free internet!', I will remorselessly pick from your trash every time.
Case closed.
Perhaps life really is full of possibilities.
Though slightly off topic from image inversion I'll put in my 2 us cents.
As a HAM radio operator I use an "embedded" PC running Xastir in my vehicle to track my location, the location of other HAM operators, send brief text messages and for the reception of weather alerts. I find it VERY useful if I can locate an open access point which further allows me to download live weather radar images, check on forecasts, etc. While I realize the "theft" of their service is considered illegal by most I hope it would make some aware that if they own a wap, and the weather is severe but you're brave enough to leave your equipment on you might consider removing security from it, especially if you see a vehicle with lots of antennas roaming the neighborhood.
Now, please don't confuse the black excursion with loads of antennas for a HAM radio operator. That is likely the NSA or RIAA/MPAA looking for goodies. The HAM guy will be in a beat up 80's model vehicle and likely be short, fat, and pale, much like your typical WoW player, except older and more intelligent. (Just Kidding!!)
Anyhow, there are both positive and negative aspects to open WAPs, the best anyone can do is educate people about the consequences and once that happens, I guess us HAMs will have to go knocking on doors.

Well, actually that's not too far off...
My last traffic ticket was in 1978 for 'five over' on the freeway...

From my livingroom right now, my laptop can see 6 WiFi signals strong and stable enough to connect to, plus mine (which is locked down by passwords and MAC addresses).
Of those six 'other' bases, I only know where one is - my upstairs neighbor. The WiFi nets in this apartment complex make for a pretty thick RF soup...
Of those six 'other' bases, only two are set up as other than "wide open" to all comers.

Theft of services implies that there is some kind of contract for payment before services are rendered, yes? That might fly if the person advertised selling access to their WiFi. Hmmm...I wonder what the TOS for their ISP says about that sort of thing...
Perhaps you mean denying the person the use of their own bandwidth? Hardly a problem if you aren't torrenting or doing anything else stupid, so I doubt it would have any meaningful impact on the person's intertubes.
Maybe in some jurisdictions you could get away with "unauthorized access to a network" but if the WiFi is wide open without any form of encryption I think defining authorized access becomes awkward.

['[S]ome of the "best" comments (obviously there's some subjectivity to it) are ones that may not be as highly moderated as some decent ones which happen to have been made earlier and therefore had more time to be moderated up.']
:)
"That sounds a lot like "Moderation is broken"."
Well, I guess the way I'd put it is more like "Moderation is imperfect." That's one reason it's constantly being tweaked; it's certainly broken compared to Utopia! But until time can be manipulated like play-doh — or cookie dough, or any kind of dough — older (earlier) comments are always going to have been, just by definition, available longer for moderation to take place. Moderation is helpful, but will never be the one true path to enlightenment
Another way of saying it: moderation lets Slashdot function as an extended conversation, not just a shouting match; that's a seemingly low goal to shoot for, but it's a trickier thing to achieve than it sounds, and calls for a lot of juggling. I am very glad that there are clever, thoughtful coders who stew over the details. (And if there's a specific bug you think could be fixed in the moderation system or other parts of the code that runs Slashdot, they take requests.)

I found the ballistic vegitable analogy funny, if very flawed. It reminds me of a Trailer Park Boys scene:
TV Engineer: Get those dishes off that roof
Ricky: What's the problem? It's free TV
TV Engineer: It's not free!
Ricky: Look, you're the ones beaming your TV signals into my trailer park without my permission from space. Do you own space? No, NASA does
Roll on the replies about a) two-way data transfer compared to one-way broadcasting/receiving, b) free-content advocation that TV IS free and c) either comedy-memorising, or bored-googling, people correcting my quotation
This is rather insightful IMHO.
(no joke)
Arguing with an engineer is like wrestling a pig in mud. Soon, you realize the pig is dirty, and he likes it.
Although I may presume that your network connects sanely to the internet, you are not obligated to give me what I expect unless I have some sort of (explicit or implied) contract with you.
If you decide to provide fuzzy pictures where I expect normal ones, that's my problem ... I only have the right to intercept your radio waves. You have the right to broadcast whatever you want in response to my own transmissions.
YOu only hav problems if you decide to spuriously broadcast kiddy porn or other illegal/harmful content in response to my signals. Just because I expect something doesn't obligate you to provide it unless I'm paying for the privelege. If I'm leaching, off of you, you can give me whatever you want.
Now. someone like Starbucks which is providing signal to encourage customers would be a different case... They're trading their signal for my business, which (arguably) produces an implied contract. It's a different case than my "unsuspecting" neighbour.
Sometimes boldness is in fashion. Sometimes only the brave will be bold.
Reader "Sloppy"'s comment reminded me of a piece of software called "sloppy". It is a proxy you can use that throttles a connection to make it look like you are using dial-up speeds. I've set it up for QA departments to test websites. :)
He could use it to violate net neutrality and make two-tiered net access!
Unfortunately, the demand to be "hip" means that individual web pages require N bandwidth to download, which is also increasing along an exponential curve. This Slashdot page was 194kb (text portion only) when I hit "reply". That would have been an insanely large download 10 years ago. CSS is helping to keep the size of web pages under control, but most of the gains are being lost to flash, etc.
It's a classic example of the stupidity vs ignorance debate.
The guy could be an actuary or a brain surgeon, and be just as "stupid" about wireless networks. Did you know that a Mark II Hoofengaffer can't be used on someone with a frontal lobe aneurism? Does that make you stupid? I doubt the surgeon thinks so. He might think that a surgical resident who doesn't know this is stupid, but would see your average network administrator as merely be ignorant. It's all about what you are required and qualified to know.
Simply not knowing about something doesn't constitute one as stupid, merely ignorant.
remember to loot and pillage before you burn!
Fair enough :)
I sometimes think I should change the sort order on comments the next time I get mod points, to try and even it out a bit - but when I get them I never remember. Might be nice if I could set that to happen automagically, though if I'm viewing a thread upside-down I should probably have the "Redundant" option taken away too, for safety's sake...
While I don't agree that using open wireless networks is unethical or, heaven forbid, "stealing", I would never use one for something that would affect the network owner, whether it's illegal or just bandwidth-intensive. BUT, if I move into a new apartment and don't have internet connectivity yet, is it unethical for me to pop on to a neighbor's open network for a minute to check my e-mail?
I've got a bigger question: Does anyone care?
I mean really, outside of this discussion, which as gone further into Bad Analogy Land than anything I've seen on Slashdot recently, nobody seems to give a crap. This is as far from a major public issue than anything I can think of.
Regular folks don't sit around moralizing about whether they should or shouldn't use that anonymous "Linksys" entry that pops up in the list of available wireless networks to check their email -- they just do it, if it's available and they need to use it. If you're racked with guilt every time you do it, don't do it. And if the idea of other people using your AP bugs you, put a password on it. Either way, it's a simple solution. But I really don't think it's a qualm that many people are losing sleep over in either direction.
Even if it is, technically, immoral on some level, it's so far down the list of Bad Things that a person could and probably does do in an average day, anyone who's bitching at others about doing it better be nothing less than a paragon of human existance and morality, or else they're a bloody fucking hypocrite. Seriously, I can't think of anyone that I know, who lives such a virtuous life that they should really be worrying about the morality or lack thereof, of the publicly-available/unsecured AP they might use once in a while.
Talk about a tempest in a teapot.

Thanks for the screenshots. If you strip out anything that might compromise your employer's security, you can GPL it and get other people to clean and polish it up for you! I'd certainly be interested in helping out (well, when I get back from vacation anyway).
