Firewall on 486 w/8 MB of memory

by Andy Stewart

HI gang, As part of the Lancaster MA project, there is a 486 machine with 8 MB of memory which we would like to make into a firewall. I'm seeking recommendations on how best to do this. Are we memory limited, or can this work, and if so, how? Can we put at least a minimal installation of something on this machine, or are we going to have to explore the single floppy firewall solutions such as the Linux Router project? Finally, is there somebody who would like to volunteer for Saturday 9/29 to explicitly help with solving this problem?

Single disk linux distros

by Track

Hey folks! I have been recently playing with the likes of Freesco and Smoothwall for a router solution based on a single floppy disk. I was wondering if anyone has heard of or used the same sort of setup for a webserver application. I thought I remember seeing something about "WAD" aka Webserver on a Disk. Anyone have any experience with this? TIA! --Track -- Tim Trachimowicz track at trackspace dot com http://www.trackspace.com

startup scripts & pid

by Bill Mills-Curran

I'm installing an ircd variant (ircd-hybrid-7) on a server at work. I didn't find an rpm for this newer version, so one of the people in my group built it. However, there is no startup script, so we'll have to cook one ourselves. I have a question about storing the pid in /var/run. Does one of the common functions in the functions script (/etc/rc.d/init.d/functions) handle storing the pid, or is that something that most daemons have built-in? I've found shell code for killing processes using the pid from /var/run, but nothing for storing the pid. Another question... Is there a decent template for writing our own script? I hate to reinvent the wheel. (I never seem to get it very round.) Any suggestions? Thanks, Bill

I downloaded the 2.4.9 kernel and built myself a new, up to date kernel, which works fine. I can run 'make bzdisk' and it dd's the kernel to the floppy. When I try to boot the floppy, I get loading ...............................................

Re: Laptop recommendations

by Robert L Krawitz

I found an HP Pavilion 5470 for $1500 at Circuit City. It was a return. It's only 1024x768, which is less than I want (although it is a 15" display), but with 256 MB, the price, and the combo CDRW/DVD drive, it looked awfully appealing. I have 14 days to decide whether to keep it (there's no restocking fee, since it was an open box). It has a non-Lucent lusemodem. The processor is an Athlon 4/1GHz, for what little that's worth; it's way, way cheaper than anything similar on Pricewatch. According to http://www.deater.net/john/PavilionN5430.html, it's possible to run Linux on it, albeit it uses a not very well supported Trident chipset, among other things. Is anyone familiar with this laptop?

Re: [Wlug] Unable to obtain an IP

by Mike Frysinger

i thought the fact that my 3com nic [a 3c905] was odd in the fact it was using the module 3c59* until i looked for the driver via google and looked at the doc's on it in the kernel help page ... the module that is called 3c59* supports all of these nics: x "Vortex" (Fast EtherLink 3c590/3c592/3c595/3c597) x "Boomerang" (EtherLink XL 3c900 or 3c905) x "Cyclone" (3c540/3c900/3c905/3c980/3c575/3c656) x "Tornado" (3c905) x "Hurricane" (3c555/3cSOHO) ... the original driver was meant for the 3c59* nic's, but the original coder found that other, similar 3com nic's had no linux support, so he added in a bunch of 3c90* nic's to his module, but retained the original name. thus, keep the 3c59* module and dont change it, when i forced usage of 3c90*, it broke my nic [i.e. it didnt work], but the 3c59* worked fine -mike ----- Original Message ----- From: "Eric Frederick" <efreder1(a)hotmail.com> To: <wlug(a)mail.wlug.org> Sent: Thursday, September 13, 2001 02:55 AM Subject: Re: [Wlug] Unable to obtain an IP > > EF>I reinstalled Redhat 7.1 on my computer at school and I am unable to > > EF>connect to the internet.

However, it is using the 3com59* driver. I tried to switch to the driver to 3com90*, but my computer stopped recognizing the card so I doubt it is a driver problem. (Plus, it was using the same driver last spring.) I also tried pump -i eth0 and it failed. Also, I entered an IP hoping that it would pick something up but that does not work either.

Re: [Wlug] boot images -- safe to delete?

by Ben Dow

Ok, first off, repartitioning isn't really all that bad, at least in my experience... you just get a partition magic 4.0 or higher (for ext2, at least... I doubt even the latest version has support for the more esoteric filesystems... but you probably don't have to worry about that) boot disk, boot off of that, tell it to resize the partition, go out, see a movie with friends, and by the time you get back, hopefully it's done... I haven't tried any of the open-source Linux tools for that, but that doesn't mean they won't work just as well. As for the kernel images, well, I'm a fan of compiling your own kernel so you don't need any of them, but that isn't for everybody, I know, so yes, you can safely delete the uncompressed versions. And unless you have a multiprocessor machine, the smp kernels aren't doing you any good either. If you delete anything referred to in lilo.conf, make sure to re-run lilo (preferably taking that part out or pointing it somewhere else), or else you probably won't be able to boot. Beyond that, I'm not familiar with Redhat and their packaging system to say what kind of stuff you'd be able to safely delete without interfering with the upgrade process... intuitively, I'd say something non-essential that you're sure is going to be replaced anyway (kde and gnome come to mind), but again, don't listen to me; I don't know what I'm talking about.

REMINDER: Meeting, Wed. Sept. 12th

by Andy Stewart

HI everybody, This is a reminder about the upcoming WLUG meeting, to be held this Wednesday, Sept. 12th, at 7 PM in Kinnicutt Hall on the WPI campus. Directions can be found on the WLUG website. I would like to spend part of the meeting discussing a potential group project. I was contacted by Warren Rasmussen, the Director of the Lancaster (MA) Center for the Aging. He would like to convert several of his office computers from Windoze to Linux, with shared printers, network, shared dialup modem, etc. Warren would also like us to entertain the notion of the creation of a few Linux workstations to be used by senior citizens for e-mail and web surfing, again, using Linux. Some training of the seniors would be required. He'd like to see if we can prove that Linux is easy enough for seniors to use. I have invited Warren to the meeting, so we can get more details from him at that time, and then gauge the interest level of the group in participating in this project. Since the WPI school year has just started, I would like to take the opportunity to introduce any WPI Linux Association officers who might be in attendance. I also plan to open the floor for tech support questions aimed at the group membership. I may still have an item or two that I can bring for a raffle. Afterwards, we'll adjourn to the Boynton Restaurant for some pizza and beer, and all are welcome to attend. See ya later, Andy -- Andy Stewart Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org

boot images -- safe to delete?

by Bill Mills-Curran

I tried to upgrade to RedHat 7.1 tonight, and I found that I do not have enough disk space on /. So I have 3 options: 1. Fresh install 2. Repartition 3. Clean up As much as I'd like to repartition, I'm not sure enough of myself to plow into that, although I'd like to hear what tricks there might be that would make it easy (easier?) to do. One thing I've noticed is that I seem to have extra kernels around, but I thought I'd see if there is any reason I need to keep them before I whack them. Here's what I have: ls -l vm* -rwxr-xr-x 1 root root 1621659 Aug 22 2000 vmlinux-2.2.16-22 -rwxr-xr-x 1 root root 1739279 Aug 22 2000 vmlinux-2.2.16-22smp lrwxrwxrwx 1 root root 20 Apr 16 22:51 vmlinuz ->vmlinuz-2.2.16-22smp -rw-r--r-- 1 root root 627379 Aug 22 2000 vmlinuz-2.2.16-22 -rw-r--r-- 1 root root 654459 Aug 22 2000 vmlinuz-2.2.16-22smp My lilo has: cat /etc/lilo.conf boot=/dev/sda map=/boot/map install=/boot/boot.b prompt timeout=50 default=linux message=/boot/message linear image=/boot/vmlinuz-2.2.16-22smp label=linux initrd=/boot/initrd-2.2.16-22smp.img read-only root=/dev/sda1 image=/boot/vmlinuz-2.2.16-22 label=linux-up initrd=/boot/initrd-2.2.16-22.img read-only root=/dev/sda1 So, I can get of the uncompressed kernel images, right? BTW, when considering my options for repartitioning, I do have a DAT drive for backup/restore ops. Thanks, Bill

Re: [Wlug] Anyone played around with Linux on iPaq?

I'm using QT-Palmtop right now on my ipaq. It's pretty nice, There are a few things missing from Qt-Palmtop. My ipaq will not wake up and alert me of appointments, there's not natural hand writing recognizer (like MS's transcriber), only since character recognizer like palm. you can't Turn on/off the backlight by holding down the power button (i found that to be useful). Also there's no real sync utility, so you can't sync with other apps, like kmail for email, etc. Those are some of the problems that i see with linux on the Ipaq as of right now. But people are working on solutions. A big plus for me is that i can access my Ipaq from my linux machine, since i don't have a windows machine i couldn't access it at all before with WinCE. Also if you don't like something in application you can change it and re-compile (handhelds.org has a cross compiler to compile apps for the strong-arm processor). installing linux on the ipaq, can be kind of tense, so if you do decided to install make sure you read the instructions thoroughly first. --brad

Re: [Wlug] RHL 7.1 upgrade: Xterm bizarre, etc

Others came as a distressing surprize: for instance the sendmail upgrade changes default behavior radically in that it is compiled against the tcpwrappers library, so now you need to consider sendmail entries in your hosts.allow and hosts.deny. Actually, that's a great idea, but I sure wish I knew that before hand (rather than bouncing mail for 2 days until I discovered the problem.) That change, among others, is clearly documented in the release notes which you should have read before upgrading. peter> I usually don't run xdm (runlevel 5 default in RedHat) but just do a startx. When I do that everything seems pretty OK until I actually try to *do* something. I click on the Netscape icon in the panel on the bottom of the screen. Nothing. I launch an xterm to try to figure out what's happening (or not, in this case) and it just gets worse: the keys don't seem to be matched up to the correct characters. When I press the 'o' key, I get a 'p' on the screen. When I press 'i', I get 'o'. In general it seems like the whole keyboard is just slid over by 1 key -- but I can't seem to find a key that gives me an return or enter. Check for an erroneous xmodmap or xkb map file. They are usually in /etc/X11/xdm, /etc/X11/xinit, or your home directory (.xmodmap or similar). I would try moving these out of the way first, if they exist, and see if that helps.
