(for example, it might be nice to have a LAN at home with 18.100.x.x, but i'll bet MIT would have something to say to you if you tried to connect that to the 'Net...) for private networks, there are a few generally accepted networks that work out, since they are Officially Unassigned. try something in the 192.168.x.x range. if the LAN and the Dial Up are on the same machine, there might be a routing issue on the local box.

At least nothing turned up on a full grep of the 2.4.9 sources.

lost in kernel

by Brad Noyes

Hi all, Has anyone else had trouble finding an option in the kerel config? I was looking for support for /dev/imon (for libfam), but i just can't find it in the kernel config. The kernel has become huge, and hard to find things in. anyone have an easy way of looking for an option in the kernel, or does anyone where this /dev/imon option is in the kernel? Thanks, --Brad

Unable to obtain an IP

by Eric Frederick

I reinstalled Redhat 7.1 on my computer at school and I am unable to connect to the internet. I have only been using Linux for about 7-8 months and I am still a novice. When I was using Redhat 7.1 last spring, it worked fine. I am using a 3com Etherlink card (the driver is 3c905c-tx in windows) and my computer seems to detect it correctly. 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. Does anyone know what could be done to resolve the problem or at least direct me somewhere. Thanks, Eric

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.

Linux Journal article by Rick Gorton

by Andy Stewart

Hi gang, Check out the August 2001 Linux Journal article on page 22 entitled "Kernel Tuning Gives 40% Gains" by Rick Gorton. The article describes work that was done to the Alpha specific portions of the Linux kernel to optimize its behavior for the 21264 (EV6) Alpha processor. Rick has attended many WLUG meetings in the past. Way to go, Rick! Andy -- Andy Stewart Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org

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
