Linux, dhcp, Resnet, aaargh

Postby Leo Comerford on Tue Dec 02, 2003 1:20 pm

Currently my PC connects fine to Resnet when running Windows XP Home, but not when running Red Hat 9 or Knoppix 3.3 . (Last year I got Red Hat 8 to work with Resnet on another computer.) The same computer has successfully connected to someone else's Ethernet network via dhcp when running Knoppix 3.3 - I didn't need to do anything - so I suspect that some evil quirk of Resnet's dhcp setup is to blame. I've run dhclient under RH9, and indeed it happily starts up and gropes around for a dhcp server but registers no reply.

Does anyone know what to do? There's surely got to be someone out there who's got RH9 working in their room...

Stranger things have happened, I suppose. But I suspect that ITS will neither know nor care (Linux isn't supported, dontchaknow).

I've got RH8 running fine, all I needed to do was tell the ifcfg-eth? to use dhcp rather than static assignment. I run dhclient-3.0p11 without any major issues, outside of a slight delay when it negotiates the IP with the dhcp server.

I do recall the dhcp client in rh9 (dhclient-3.0.26) had issues (I helped a mate set his linux box up) but using dhcpcd (http://fr2.rpmfind.net) from rh 7.2 (the i386 rpm) was fine, even getting past the pause that I get on dhclient (once I had manually run dhcpcd once).

DEVICE=eth[?]
BOOTPROTO=dhcp
ONBOOT=yes

is all I have in my ethconfig file.

hope this helps.

Thanks - following the advice you and a couple of other people gave me, I installed dhcpcd, and it Just Worked. Beware though - versions of dhcpcd prior to 1.3.22-pl2 apparently have a nasty security bug (see

http://www.securitytracker.com/alerts/2 ... 05874.html

). So your friend might want to upgrade. The RPM I used was

dhcpcd-1.3.22pl4-3mdk.i586.rpm

.

Leo.

" versions of dhcpcd prior to 1.3.22-pl2 apparently have a nasty security bug"

Its not surprising, its a pretty old distro now.

I've often been tempted to try mandrake rpms on RH, given their common heratige. Glad you found an answer though :)

A final note, really for the benefit of anyone coming across this later when looking for answers to their own problems:

As of this writing, Fedora Core 1's DHCP client works fine with Resnet out of the box.

I'd never have a win32 box direct on resnet. Your vscan comment confirms all that is wrong with windows. You shouldn't need a scanner, after all, linux does just fine without one.

And at 100 days up (b*stard power dip) I can't complain. Name any windows box that you can fit and forget.

Haha! so funny, good joke there in deliberately picking the worst and most unreliable and inefficient virus scanner, lol :D

Norton is a piece of dog poo.


Never mind the fact that it guzzles system resources when it's running. It's hueristics aren't that good and it is crap basically.

Hey, guess what? Ubuntu 5.10 (Breezy Badger) uses dhclient v. 3.0.2 . And Resnet doesn't work with it. I have yet to confirm that dhcpcd works properly with Resnet, partly because I have yet to get it working properly on Breezy.

If any kind soul has experience of getting Breezy and/or dhclient working with Resnet I'd be grateful to hear about it.

Bollocks. I've only just gone to the trouble of downloading Breezy Badger. Ah well, let's see if we can figure out a fix.

I have dhcpcd working fine on gentoo - all I had to do was emerge it, I didn't have to change any settings or anything, as far as I can remember anyway.

i don't see the issue with just not using dhcp. I mean, it's not like your computer needs to change IPs in the whole time you are on resent.

Anyone questioning how I post on the sinner, my new way of life, will offend my "religion" and as such will be dealt with in manners inclusive but by no means exlusive of death threats, random acts of violence, maiming of the general public not involved in this matter and finally a Jihad from all my fellow religious sinners.

For years we have been oppressed by you post nazis, the time of change is upon us.

ResNet IPs are static, but they change if you either connect to a different socket in the University, or also if you change the MAC you've registered with ITS.

So I guess you're right in not needing DHCP.
