  1. Client-side 802.11 converter on 802.11b Network Scanning In London And Amsterdam · · Score: 1

    While we're waiting for the site to become available again, I have a serious question that I hope someone can answer..

    has anyone seen a device that will convert a single PC to wireless that absolutely cannot otherwise be converted? I have a small mainframe at home that's really an S/390 chip on a Microchannel card (IBM all the way, baby :) and its in my downstairs office. It will soon have a microchannel ethernet card, but obviously there's no way in hell I could convert that puppy to wireless.

    I'm looking for an access point-sized device that will just be a client side relay for one or more PCs connected to it. Has anyone heard of such a thing? Thanks..

    I have the same *exact* AP as you. If you had bought the version that has just the single internal port and the parallel printer support, you would have gotten the "MAC accept list" instead of the "MAC reject list" we got stuck with. I use Orinoco Silver cards with it under Linux and Win2k.

    Here's something important to look out for. Because I've been getting my network "broadband ready", I run my Linksys behind an autodialing Linux firewall with a 56k modem. I run extremely tight rules on the firewall, too, and just the other day I logged some packets from my network behind my Linksys hitting my oustide firewall with the **protected network** IP network address!

    My setup is 56k ppp -> Linux (192.168.2) --xover--> Linksys WAN port --> hub port (192.168.1 w/DHCP) --> 24 port hub

    I should *NEVER* see 192.168.1 packets going OUT of the Linksys and hitting the eth0 on my outside firewall, but sure enough.. I logged a few the other day.. they were destined for junkbuster and squid. I'm glad I have the firewall logging anomalies like that or I would never have known.

    Luckily the outside firewall stopped the malformed packets from getting out to the net. And no I don't care that much about it on a ppp link, but the cable modem is coming and I don't want my internal network structure revealed on the Internet side.

    I'm recovering at home from summertime surgery and asked last week to be allowed to return to work on Monday the 10th. They haven't processed my paperwork yet, so I was still at home on Tuesday when this hit. All day Tuesday my condo was like the Circuit City "soccer fan" ad, I had the living room tv, the downstairs office tv, the bedroom tv, and the upstairs office tv (tv card) all tuned to CNN so as I backed out of one room, I could snap turn my head and look at another tv in the next room!

    That lasted until Tuesday night, when I finally setup my station in front of the big living room tv. I never tuned off of CNN from Tuesday morning until Wednesday afternoon just to watch the local news for a local spin on it. Sure enough there were about four or five victims from my tiny little town (Lower Makefield, PA).. including the captain of flight 93 that crashed near Pittsburgh.

    I've always been such a news junkie though, that for a couple of years many members of my family would call me for little known facts about stories, local or otherwise. But with this, I truly became frustrated with my dialup access. It was bad enough that the news sites were slashdotted, but to not know if the slowness would have been at least a little more bearable with broadband really killed it for me. I've really been here more than any other site. /. is so freaking awesome, its beyond words. There are some real kooks here, but the functionality is just stunning.

    Does anyone here still browse the VBI data from CNN? Are they still sending any? Did they send cool stuff like photo galleries? My tv card is running on NT server at this time, so there are no VBI drivers for NT from Hauppauge AFAIK.

  6. Suck it in and do it.. on How Do I Sell Telecommuting to My Employer? · · Score: 2, Interesting

    A little over 10 years ago when I was 19, I used to daydream about working at home. I read a book who's title I can't recall, but it's subtitle was "everything you need to know about working and living under the same roof". That was a great book. It had all kinds of tips, including how to approach management, how to discipline yourself, and how to setup your work environment. The author (authors? husband and wife I think..) even gave anecdotes like the one about the guy who would walk out to his backyard every morning, open and shut his car door to start his day, and repeat the process at night to end his day.

    The first time I worked at home I needed to write some perl code to make a Linux box telnet to an OS/2 console and manage the network from a command line. I had a good junior admin whom I trusted, and I explained to the director that I would get the my work done much better if I took an old OS/2 server home and worked there instead.

    Also right from the book, I promised that if I did leave the house during the day, I would always have my pager, and I would never be more than 60 minutes from the office. That either kept me at or very close to home.. no wandering around all day. I also promised that I would come right in to the office on a "home day" without any argument should I be asked.

    One night, a server in another building crashed and my jr admin was on it. We spoke by phone for a few hours and I finally decided to go in. When I told the director I was coming in, she said, "oh thank God. I was hoping you would." I said to her very sternly, "we have an arrangement here, and I promised to come in as soon as you asked. I thought [he] could handle it with my instruction, but if you wanted me here, all you had to do was say, 'please come in' and I would have jumped in the car right away." She appreciated that, and we went out for drinks. My work-at-home project was very successful, and when the jr admin quit, we replaced him with my perl scripts, which they appreciated very much :)

    Fast forward 2 years to Dec '00. As an IBM consultant, I am 'hired' to work on projects, either internal or external. I was about to be let go for the 1st quarter, but I felt we were leaving the customer with inferior procedures. I told my project manager what they needed (an automated NT server build process) and what I needed in order to put it together (a server and 3 months at home). They accepted my proposal, and I spent the wicked Philadelphia winter warm at home.

    As far as distractions go, I absolutely had to tell my wife the first time I worked at home, "honey, when I go in this room and close the door, it's just like I'm in New York City. You can't keep walking in here and sitting down to chat with me." At first she argued saying "but I don't know when you're not going to be here everyday anymore." I replied, "if you don't let me work, it'll be sooner than later."

    If you don't have scheduled times to meet with or speak to people, its absolute bliss. They basically told me, "see you in 3 months". I worked whenever I felt productive, even 1am on Sunday nights. I worked with my brain's clock, not my wall clock. I could take my wife (or myself) to the doctor, go shopping if I needed people contact, and most importantly work whenever I was productive. I know I had it extremely lucky, but I've had extremely good luck working at home.

    I'm glad I had hints about how to go about "being the first one" in the office to try it out, and I'm glad I've known how to work at home before joining IBM where they practically force you to get used to not having any handholding! God damn I love my job.

  7. roll your own GnuPG on Net Taps Without Warrants? · · Score: 1

    I asked my shell account sysadmins to upgrade the system level gnupg from 1.0.1 to 1.0.6 a couple of weeks ago.. they've been moving slowly, and when this happened I gave my shell account my own upgrade. If you have a non-root shell account and the sysadmins are not offering or updating GnuPG you can build your own.

    Download and unpack the code in your home directory. It will create a new directory gnupg-1.0.6. CD into that directory and run

    ./configure --prefix=/your/home/directory

    and then run 'make' and 'make install'. The install will create a gnupg directory off your home directory. Update your ~/.bash_profile and add ~/gnupg/bin to your PATH.

    Next you can google for incorporating GnuPG with pine. It basically involves symlinking gpg to "gpgsign" and "gpgencrypt". Then configure pine to detect incoming gpg-handled email and to offer processing your outbound email just prior to delivery.

    I'm with you on carnivore, though. I think using stego will set off flags because it *will* be detected instantly. Stego is a nice idea, but the popular stuff is not ready for primetime. As I've said before, at best it'll let you widen your distribution channel to include virtually every usenet newsgroup. You can stego binaries in binaries, but you can also stego text in text. By uuencoding parts of binaries or ascii armoring gpg'd parts you can literally stego anything into anything. Doesn't mean the spooks won't be able to detect your efforts. It just means you can spread your stuff out over a *much* wider area.

When the US and soviet Union finally had enough weaponry so as to assure the planet would not be left for anyone in th event of war, peace arrived as the only solution. Tremendous amounts of fear led us towards peace.

    Think back to that theoretical 7 eleven outside Phoenix. The criminal would never think he could pull off a robbery of a store full of gun carrying customers. I never suggested a huge shootout in the shop with half the customers dead. I only suggested the would-be criminal turning around and walking out when he saw all the guns on the other patrons' hips.

It's the next move in the war on Americans. Hijack planes full of Americans and plow them into buildings chock full of more Americans.

    I think at this point those discussions are few and far between because Breaking News events keep peppering the regular shows. Things like the House and Senate being evacuated.. the Empire State Building being evacuated, the eight arrests at LaGuardia and JFK, the arrests on the Carnival Cruise, the FBI raids in Boston, Florida, and now Seaside Heights, NJ.

    In the Tampa comment, I indicated that I haven't commited a crime that would warrant the face cameras to start setting off alarms at the police HQ. And I certainly don't have a history of shoplifting and have nothing to worry about in Borders.

    But when it comes to securing email and transactions, I want all the privacy I can get my grubby little hands on. 90% of my email never leaves the box my close circle of friends use, and we are required to ssh in. No, my Mom doesn't encrypt her email to me, but I would love to see AOL incorporate GnuPG into their product. Imagine their addressbook having a field for the public key, and a checkbox for "always encrypt for this recipient". Even if they water it down by reusing the login password as the gpg password, at least it'll be encrypted in transit.

    I'm closing this without deciding whether or not I would support AOL including strong encryption with key escrow to the feds. If you want true, escrow-free encryption, get a real ISP. Do we really want to make it easy for 20 million people to immediately start encrypting email in such a way that the feds can't get to it? Is it *really* that bad that instead of just two people being able to read an email, we add a third reader whom we need right now more than ever? I don't know. With all the abuses of power, I don't know.

    I'm telling you, in this era of keyboard loggers and key escrow, if I'm presented with the opportunity to obtain one of the Linux wireless webpads at work, I will get one. A fully self-contained Linux client with touch screen and an optional on-screen keyboard. Strong encryption will make that about the securest thing I could find right about now.
