One Machine, Multiple NICs, and a single Newbie

CozyMel · 10-02-2002, 03:50 PM

I'm trying to prove myself at this new job, I've managed web/ftp/dns...the works, but all on MacroSloth. I've been given two Linux servers, both of which had been loaded with RedHat 7.1 about a year ago, not by me. The boss doesn't want to reload...not incredibly sure why...but he's not sure what he's loaded and I have no idea what he was going by.

Anyway, one's an FTP/WEB server that I'm trying to figure out ftpchroot on, the other is an FTP/WEB server that was supposedly up and working months ago, that I'm supposed to figure this out by.

I guess the problem I'm seeing with this second machine is that it had one NIC, up and working "fine as a server." The boss wanted to play with Proxy after that, and loaded another NIC. Now neither of them access any outside world. I'm so completely new at this, I don't even know how to load a driver, and I REALLY DON'T KNOW WHERE TO START TO LOOK AT THIS PROBLEM!!!

Please help if you can!!!

ok, first things first: can you verify if the second nic is running on the proxy wanna-be?

I'm guessing both of these are inside a network, and not your isp's access point? first of all, make sure that the correct default gateway is set for all of the network interfaces.

your dns address should appear in /etc/resolv.conf ex:

nameserver 206.13.28.12
nameserver 206.13.29.12
search localdomain

I don't really know much about using redhat, but i'm just trying to give you some pointers. I think that you might have "linuxconf", but I heard that it's buggy. You should put "webmin" on your system if you can.... I've heard it's a really good web-interface configuration tool.

Good Luck

Do the following on each of your two machines.

O.k.
First do an lspci

This will show you all the devices on your pci bus.
You should see two ethernet adapters.
Please post back what type they are.

Second do an lsmod, this will show which kernel modules are loaded.

third reply with contents of /etc/modules.conf
[could be /etc/module.conf ]

This will show which modules are to be loaded at boot time, and
what they're aliases are.

Fourth reply with output of ifconfig. If you're machine is publicly visible, edit out the ipaddresses from the output before posting.
