Slashback: Snapshots, Amends, Bazaarity
Microsoft is just as secure as the competition, says Microsoft. Jon_E writes: "According to this article Microsoft is responding to the Gartner Report which recommends that enterprises drop IIS by claiming unfair targeting due to their popularity."
Whether because of better-trained or more vigilant administrators, or some other factors, the Apache servers running many web sites certainly haven't seen the devastating outages in the past month (Code Red, Nimda) as certain large IIS installations have.
If animated, this might make a really good Saturday cartoon. cconnell writes "Last September, slashdot published my critique of Eric Raymond's essay The Cathedral and the Bazaar. There was a lively (and sometimes scorching) discussion that followed. Here is Eric's reply to my critique, which Slashdot readers might enjoy. And here is my reply to Eric."
This was not faked in the same studio as the "lunar landings." mrsmalkav writes "Deep Space 1 has passed by Comet Borrelly within 1400 miles and took some very pretty pictures of the comet's core, all while collecting lots of data about said comet. NASA's press release discusses some of the details and findings of the flyby.
This is actually really impressive given that there was very little hope for this mission. From the Mission Logs on DS1's site, '[T]o be honest, DS1's visit with the comet simply is unlikely to work as well as we hope. Many mission logs have described the difficulty of keeping this aged and wounded bird aloft, and the encounter with Borrelly will present Deep Space 1 with the greatest challenge yet in its historic trek through the solar system.'"
Saint Aardvark writes "Space.com has an article about the images taken by DS-1, and they're stunning." And eldurbarn points to the NASA Images of comet Borrelly online at JPL.

This is simple physics, boys and girls.
First things first, you need a spacecraft as light as possible. Anything not needed goes away. Basically, you're left with the instrumentation, the navigation, the cameras, solar panels, batteries, and a couple of sizeable tanks of xenon.
Yes. Xenon. The heaviest non-radioactive noble gas.
Now, xenon is normally inert like other noble gases. I mean, there are no natural compounds containing any noble gas because they have no natural need to enhance their electron shell configuration.
However, xenon is pretty large (as atoms go) and, given enough juice (courtesy our light and ability to live, the sun, hence the solar panels), you can ionize xenon. You can strip off an electron or two and it's useful (For example, the compound XeF6, xenon hexafloride. What it's good for? Dunno. Still doesn't change the fact it exists.) More importantly, it's charged and can be directed.
Then, it's a simple matter of a small aperture (which can be directed), a positively-charged grid, and the xenon leaves in the direction opposite the spacecraft goes.
Don't expect this to power any spacefighters, however. At full power, the force this produces will barely move a piece of paper in front of it. The beauty of ion engine, though, is that because in space, inertia isn't hampered except by collision or a gravity field, this little bit gets larger as time increases. It's not much force, but given time it gets zooming.
I used to be someone else. Now I'm someone better.

Worms dont happen to Mac web servers running WebStar.
.exe because macintoshes do not have file suffixes. The mac OS (9,x and older) uses a four byte file type designator that the user never sees and cannot be set carelessly.
EVER.
Thats why no reports of ANY exploit has ever been published regarding the secure Mac OS. !
consult bugtraq if you doubt this.
This Gartner report is a sham unless it really discusses techical issues regarding the macs securuity as a web server.
C Language alone is not the sole reason but the types of STRINGs used in ANSI C libraries certainly adds risk.
Worms dont happen to Macs because Mac programmers rarely have buffer overrun problems because mac apps typically NEVER use null terminated strings and intead use "pascal" style strings that have a bounds of 255 and a marker in the front.
Additionally mac programmers tend to know that there is no false sense of security because all code is running at supervisor level so programs, like Webstar, are careful not to do foolish things.
Mac programs and executables NEVER can run merely from a data file named with a suffix such as
A further reason macs are more secure than unix (hundreds of documented exploits) and Win NT (almost as many exploits documented over the years), is because the mac does not have a command line shell and has no path to hijack. No command line and a modern type of interprogram communication prevent the silly weaknesses in other OSs.
Yet another reason the Mac is secure is vecause a mac program (either 68k or PowerPC) needs TWO files to execute and not one file. The second file is called the resource fork and it is genreally an invisible file kept tightly associated with a file. classic internet apps do not create or allow creation of these resource forks as side effects of merely storing data files. Macs are very secure from infiltration by dynamic creation of apps by rouge products on a server
Another reason macs have NEVER been broken into running the WebStar server is because the mighty Mac OS Webstar server, (which typically costs over 400 dollars unfortunately), avoids ever executing cgi code files from directories where they ought not to be. A clever set of directory and folder control prevent the webserver from being hijacked unlike earlier versions of apache.
The US army switched to Webstar webservers on macs when MS NT webservers kept getting hacked.
There are thousands of major webstar servers out there. I think many are colocated at reprahduce.com cages.
And mac NEVER get hacked. EVER. and NEVER have, even with public challenges and reward money.
Sure, there may be some defects that might get discoverred one day, and surely any mac not runnning mac os such as ppcLinux, or MAc OS X (freeBSD derivitive) are hackable.
But face it. Macs have NEVER been hacked and that is because of modern and sound design principles.
Myself and other mac programmers I know have NEVER shipped a product containing a single null terminated C string, and do lots of paranoid error checking as well.
Unix is hackable not because of open source, not because of popularity (both of which help) but because of all the things I mentioned here.
But I agree about the other OS's sucking. parts of the older Mac OS itself is written using pascal strings, in fact the original ROMs were written using only pascal compilers and some assembly, and no C. But string overruns alone are not the ONLY reasons mac servers have never been hacked, (command line, dual fork, no extensions, etc etc).
Wake up and quite being bigoted. "Never" is a good enough abosolute ajective for most logical people to draw up reasoned conclusions from.
Could we, in fact, turn a Disney DVD into a terrorist tool? Has it already been done? Should we be encouraging Congress to ban the CSS encryption scheme because it could have been used in such a way? Interesting questions, no?
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Code Red and Nimda did not attempt to hack commercial sites. They relied on large numbers of (poorly |un-)secured servers managed by sleeping administrators. Judging by a sample of the attacks that came my way, I'd say 80% of the machines were running servers that the admin didn't even know about.
And given the growing number of machines now equipped with an unnecessary webserver, matters are set to get worse.
At least all the admins I was able to contact (with one exception) stated that they were now considering a UNIX-based solution for public webservers!
Actually, the they switched everything over to .99 and .95 with the invention of the cash register, the idea being to force the cashier to open up the cash box to retrieve change, which makes it much harder for them to pocket the cash for themselves without anyone noticing.
"Mind, as manifested by the capacity to make choices, is to some extent present in every electron." -Freeman Dyson
Uh, most people (on cablemodems/dsl) that got hit with nimda are running a pirated copy of NT server. You see, legal home users would most likely be running 98/ME or NT workstation, since it's cheaper and they wouldn't get any benifits from nt server. But the warez kiddies are all running nt server, since they didn't pay for it. And they go through a full install, since they might as well have the whole thing on their 'puter (for bragging rights)...
This is taken out of context - the quote refers specifically to the Hotmail hole that allowed the reading of a specific user's mail. The quote has nothing to do with IIS as the hole is due to the poor design of the CGI backend. In other words, the Hotmail hole would have existed irrespective of the underlying web server.

Okay, it's time to debunk the M$ admins are lazy myth a bit..
:-P Perhaps if I had a nice farm of 600 identical boxes, I'd be a perfect admin. This is life, folks. Get on with it without making the comments -- without understanding the other side of the fence.
Here's my work environment -- the products that I'm supposed to install, after I've chosen the hardware for 700+ desktops, and maintain, after writing policies and ops documentation.
Exchange (10) Servers, IIS (7) Servers, MS-SQL 6.5 and 7 (5) servers, Metaframe/NFuse (4) servers, RAS, VPN, 45 NT servers for general ops of all this stuff, a couple of Debian boxes for internal DNS, FreeBSD running MRTG, Nessus, etc, perform 2nd level support for 8 clueless admins and 6 semi-knowledgable ones. Additionally, let's not forget the "uhh, how do I do a word merge", boss ranting about multicasting (for which I am going to modify configs on 12 cisco Routers and godonlyknows how many switches), write policy and operational documentation for all of this. Manage the "network consultants" than run DNS, e-Trust and FW-1, provide support and knowledgable comment towards a $2mil software app development process in terms of "net and O/S", deploy 2000 server *sigh* next month and ensure that everyone makes a backup occasionally. (play nice with audit, 20 mangers and two other organizations [1 that owns us, 1 that we own]).
If *ANY* of you suckers handle all that daily, and still have time to mess with patches on a regular basis, I'd love to see you in action. This seems to be quite a common scenario for a lot of mid/small size companies, in my experience.
I'd love to live in your dream world. People wonder why I'm an alcoholic.
I did realize about three months before codered that we were a screaming hole for IIS exploits. Do I have time to cull through 30+ patches and tinker with which are appropriate to apply? Nope. Result: Nimda runs rampant still this week because I've been stuck in innane meetings all day.
Now: Suppose your boss is used to having a mini-vax, and asked for CPU usage reports by dep't and individual last week. Do you see the uphill battle? We're young. Management in a small/midsize company isn't likely to even understand what they have running, less what should be paid attention to technically. Politics, Politics, Politics all day long. Yay! Well, I guess of the rest of the world got messed, it's okay that we did too.
Have fun admin'n your two Apache boxes. Good Night.
No troll indended, it's just a rant.
S.
I have been thinking about this as well as one of the places I do contract work for is getting pounded daily with Nimda and Code Red I/II attacks as well. Since the box is running Linux, the attacks don't matter but I have been wondering if there is some way that a sysadmin could take advantage of these requests to stop the attacking system.
Various people have mentioned writing a white hat virus that would shut down the attacker and all that - but in reality that just puts you in the same boat as someone attacking their system - and its therefore illegal.But if someone's computer makes an http request for a file from my server, am I responsible if what they get is not what they might expect to get?
What if I was to create a file consisting of nothing but the letter X that was, say, 1Gb in size, and leave it on my linux webserver with a name like "root.exe"? It wouldn't take all that many requests for the attacking system to run out of HD space. Granted service on my server might suck for a bit, but eventually if enough linux admins did this the target systems would simply shutdown for lack of swap space or HD space or whathaveyou.
Or perhaps I tell Apache to treat .exe files as PHP files and process them accordingly. Then I create a PHP script that sends prints nothing but Xs or random numbers in a long string back to the requesting server (with the execution time limit for PHP turned off). It would be like 5 lines of code total.
After all, its my server, so presumeably I put the file there for my own purposes, indicated in robots.txt that I dont want it indexed etc. If some other system makes a request for that file which I have in no way indicated is present on my system, isn't there fault/problem if the file is too big, or causes problems at their end?
I am sure the clever folks at /. could think of other things that could be done in this manner.
Just food for thought, and I would love to see some suggestions...

Now that Windows XP is here does that make Windows NT and Windows 2000 a legacy product?
And when you're typing a lot, having to switch from the keyboard to the mouse to activate a fuction tends to break your concentration more than if you can use the keyboard instead, as well as just being a pain in the arse.
I often find it faster to use the Alt + letter key combination to open a pulldown menu, and then either pressing a letter key or using the arrows to navigate to the desired function. Keyboard shortcuts are even faster, of course.
Or that double-clicking "My Computer" opens a single-pane window without any directory tree ...
That's why I never double-click it. Either I press Win+E which opens My Documents with a directory tree, or I right-click some folder and choose 'Explore'.
I also hate the fact that the default settings hide file extensions and don't display hidden files.
This sig under construction. Please check back later.
Yeah, I also learned Win-E from that boss :) Alternatively, you can go into Folder Options and edit the preferences for File/Folder so that "Explore" is set as default, instead of "Open" -- that way, double-clicking defaults to a directory tree.
You hit the nail on the head with file-extensions. That example beats the hell out of my off-the-cuff offerings any day. I can understand it for Win9x, because your average luser is gonna have a cow when he renames a file and it kicks the bucket because he didn't add an extension, but for WinNT/2k, it's an appallingly ill-conceived idea.
A word can paint a thousand pictures
As I went from desk to desk here applying patches to our various IE versions, I began to fantasize about what this job would be like if the clients had a different operating system, one which I could start a remote shell on. It would be great if I could use one of the several scripting languages I know to write a script which would run from my machine and patch all of the clients. It would be great if I could trust the patch to run from a logon script. Maybe I will learn Visual Basic some day. I still don't think that will get me there, though, because I have no idea what many of the patches I apply are actually doing. I keep seeing security advisories on Microsoft's support site that say you can: a. Change the following three registry entries or b. Apply this 3 meg patch.
HTF can those be equivalent actions? What exactly am I turning on or off with these cryptic registry keys?
But life with Microsoft is not so easy, is it? They keep sending you patches that require you to physically sit at each machine and click your way through dialog boxes, and you don't have time for that.
Where your Apache admin, who has fewer machines to patch and fewer patches to apply, can write a PERL script to do the job for him, you have to sit at each IIS box, open the control panel for each site, and click your way through the changes. Wouldn't it be great if you could SSH in and apply patches or make configuration changes from home while you watch the ball game? Of course it would.
I feel your pain, because I am dealing with it every day. The hardest decision I ever made here was to sit down with my boss, put my reputation (and job) on the line, and get permission to bring in some free technology on a trial basis. After some testing and configuration, I have replaced three NT boxes with Linux. Samba and the smb_auth libraries have made it possible to replace many NT services completely transparently. The main difference is I no longer have to come in on the weekends for "maintenance reboots" or just to make sure everything is working. My current hurdle is figuring out how to replace Exchange in a way that won't irritate my users and/or bosses. Every NT box I pull the plug on reduces my workload. What are you doing about yours?
I am not trying to be combative, but you did mention that your boss has asked you for things that used to be easy to get from his old VAX cluster. Have you explained to him the limitations imposed by the decision to move from VMS or Unix (free or otherwise) to NT? What is NT giving you guys that other systems do not? Make sure your evalutation of NT includes an accurate picture of the increased administration effort it requires.
You sound like you are pretty high in the food chain over there-- politely ask for the tools you need to make your job easier. The push for better technology has got to come from our end-- management will not do it for us. As Linux and FreeBSD gain more market share, it forces Microsoft to evolve. Believe me, they have the resources. They aren't writing cheesy hacks because they can't do any better. They are writing chessy hacks because it pays a lot more than sweating the details does. Show them you won't settle for that and we can all go back to the good old days of sysadmins who had time for the occasional game of DOOM.
The "live" checking does not autofix it, but if you right click on it, it does give suggestions that will be put in if you select it. That's what makes the F7 key so stupid. Autofix actually is a hazard if you regularly use double caps eg "JSmith said ...". Tab is bound to something that most people find absolutely irritating. I know I have to fix their docs up.
Most of my typing is done straight in markup. That is, when I type this in bold, I go {control-B}this{control-B} or {b}this{/b}. Amipro had a clever idea of putting styles onto the function keys: so if I want a header, I press F7, and if I want a body, this is F2. The table is stored in the template.
With control-c, v, and x, the easy way to remember these is that x is sissors (cut), v is glue pen tip, and c is copy. That might help.
Spell checking a document, like printing it, is a separate activity, and not something you want activated on a wrong key stroke. Going Alt-T-S, especially if you watch the menus as you do it, is not a big ask, especially if the machine does a lot of paging as it does it.
As far as your data files go, I have found a way around this is to store them in one tree, and then create an icon with the command line "explorer.exe /n,/e,/root=d:\path,folder" does wonders for file management. You can change the icon view to "List", and arange by date to get the latest to the end. Whichever way, it's better than "Large icon". Also, the back space backs up the tree. Also counter intuitive, but consistant.
