pcmcia and laptop issue
by Jenny_Hopkins＠toby-churchill.com 15 Feb '02

15 Feb '02

Hello All, just a thanks to all who have helped with my laptop and the pc card not working thing. A brief history for those not at the last meeting: This laptop originally had on RH6.2, the pc card (buffalo) wouldn't work at all. Then I installed debian with a 2.2.18pre21 kernel, and it half worked, but the interrupts kept being dropped and it was very humpty. At the last meeting we installed a new kernel (2.2.4 I think but not having the laptop here I can't check, or was it 2.4 something? I really ought to know these things but life is too short to know *everything*!) but then discovered this particular kernel handles pcmcia differently and it has to be loaded as a separate module. So last night I downloaded pcmcia.cs latest version onto a floppy, copied to laptop, configured and ran make, and hey presto! it works beautifully. Cheers, Jenny.

NVIDIA/ X

> Why would you want to play Q3 anyway? ;-) Rune and Tux Racer, actually! :-P, the driver provided by X is WELL below par (in fact unusable) for openGL games. HOWEVER, I now want it back, at least it damn well worked! :'( > No, the problem is that when they fry the system, you can't debug it. The > cause is that they are needlessly restricted. I get Mark's point, though. It would be a much better idea if NVIDIA left it open for the XFree86/kernel hackers to work on, cos they seem to have a better idea of what they're doing. Sorry to selfishly steer towards my problem. I still have a seriously fscked X configuration (i.e. it don't work), with no NVdriver module anywhere. So... this module- part of X or part of the kernel? Does the kernel load this module, which is provided by X, or vice versa? I think I'm getting confuZed here. Am I gonna have to install a kernel from source whether I like it or not now, to get the module back? OR X? How could I find the headers for my existing kernel, if they're not where they're meant to be, so I can rebuild the NVIDIA kernel patch from source?

Sometimes the answer is so simple you just don't see it! Would this *just* provide fault tolerance (if one card goes down, it gives the next IP)? i.e. not load balance. Or does it alternate which IP it gives out to the client issuing the request?

[...] Ahem, he said the NV driver that came with X, not the POS ones from nvidia.com. As long as AGP isn't disabled, it should work fine. I have an entirely healthy bias against the nvidia.com drivers from past experiences. -- MJR

OK. So I decided to test this.... I used the 'which package to use' program from Nvidia. Backed up XF86Config and XF86Config-4. I downloaded the .rpms, and installed them as root in runlevel 4 (5 starts up X). I got an error with the kernel rpm: modprobe can't find NVdriver. find / | grep NVdriver can't find it either. Where did it go? :'( I rebooted to runlevel 4 again just incase. (5 starts x it's a RH7.2 machine). I run startx . Well, all I can say is... thank fsck for ext3! I fiddled with my XF86Config-4 file and managed to get it so it doesn't lock up, but it exits saying it can't find the NVdriver module still. So I downloaded the source tars. I run a make on the kernel modules. It can't find the headers! I boot into my trusty MDK8.0 system, get online, look up every FAQ I can find and some NVIDIA walkthroughs on linuxnewbie.I need to add (apparently) SYSINCLUDE=/lib/modules/2.4.9-21/build/include Only.... there's no such path. It stops at /lib/modules/2.4.9-21/ and the contents DOES have something called BUILD in it, that is flashing for some reason. I *did* recently update the kernel due to the myriad of security errata, but I made sure I downloaded the kernel-headers package too. erm.... *eep*! >all you have to do when you rebuild the > machine is make sure your new user account has the same UID no. or you can > use the chown command as root to get access back to the files when you > have rebuilt the machine. Of course! root always has a UID of 0! I can CHOWN the files to the new user acct. groovy.

recovery from disaster/rebuilding kernel
by Ricardo Campos 14 Feb '02

14 Feb '02

I am going to attempt to rebuild my kernel (gulp). Now, if I TOTALLY screw it up (likely), I want to know if it is possible for me to preserve my /home partition, and my X configuration: 1. Will the new kernel build impact on my X configuration? I know that my kernel has the NVdriver module installed (the one that came with X 4.1.0), but I'm concerned as to whether if I rebuild the kernel from source, it will require a new installation of X? 2. I have a separate /home partition, on a separate drive (hdb) to where / resides (hda). I did this incase hda fails.However, as I understand it, even if I make a user with the same name and password and mount /home to the old /home partition, I will still not be able to access any of the files due to permissions- am I right? If so, would there be a way to save the user info on floppy/CD whatever so that if I did fsck it all up, I could just start an install from scratch and use those files to get access to the old /home? (an install from scratch being far quicker!) Could I possibly ask any more questions in one e-mail? ;) TIA Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

Multiple NICs
by Ricardo Campos 14 Feb '02

14 Feb '02

OK, I'm wondering if this is possible in Linux: One server, thebeast.mydomain.com , has 2 NICS. 1 has an IP of 10.0.0.1, the other of 10.0.0.2 . It is connected to a switch (which has a few other servers attached), and the switch to the rest of the LAN. It's a pretty critical server, under quite heavy load. Is there any way that a client could connect to thebeast.mydomain.com and sometimes connect to one IP, sometimes to another? I'm looking for fault tolerance as well as load balancing between the network cards. I know that Intel Server adapters do this on NT and Novell. Anyone have any ideas? Would it involve DNS jiiggerypokery? i.e. DNS server sending requests to 1 IP then another. Or maybe a switch that could do it? Ricardo PS please don't say "buy another server and cluster it" or somesuch. an additional NIC is FAR cheaper than another high-end server. -- Get your free email from www.linuxmail.org Powered by Outblaze

RHN users-advice
by Ricardo Campos 12 Feb '02

12 Feb '02

Just a quick question for RedHatNetwork Users- anyone had any probs updating the kernel via rhnsd? I'm usiong the latest version of that... my only outdated packages are the kernel and XFree86.... (Yes, I'm scared it may fsck up, I only have a dial-up!)

What's an RBL? I use Demon as an ISP, and with a paid e-mail account I was only able to use demon's SMTP server, rather than the one I paid for... is this due to relaying? Would this also affect me if I had an MTA on my box at home? Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze
