I just setup an old box with CentOS 4 and I'm having a very strange problem. The keyboard is functional throughout the startup process of the machine. I get the login prompt and I get just enough time to type in "root" and hit the enter button before the keyboard fails. I've tried a different keyboard but still the same problem. After a few repeated trials I've found that the keyboard will stop functioning after about 5 seconds from when the login prompt appears on the screen.
Does anyone have any ideas on this problem?
Thanks, Eric

How old a system and keyboard are we talking here? Are we talking AT style keyboard, ps/2 keyboard, usb keyboard on an old system (where bios usb handling can cause this sort of confusion) etc. Give us an idea of what we're working with.

Shot in the dark but happened to me in past. If you have setup serial mouse and it is missing / non functional you can get erratic errors on key board

Oh, sorry about that.
The system isn't real old but wasn't made yesterday. The system is using PS/2 connectors. I want to try a USB keyboard but I don't have one, unfortunately.
Out of all the problems I thought I might encounter, this isn't one of them.
Thanks, Eric

Can you ssh into the machine (from an external machine) after the keyboard locks up or is the machine locked?
Are you hooked up to a KVM switch?
Do you have the latest BIOS installed from the Motherboard manufacturer?
Is there a BIOS setting for keyboard that has a USB / PS2 selection?

I just installed CentOS so I haven't been able to setup SSH. No KVM switch and I haven't been able to find anything in the bios that talks about the keyboard. I'll check to see if I have the latest bios installed.

Assuming you opened the port for ssh during install (or disabled the firewall altogether) it'll set itself up for default access. This is so you can configure remote machines and such. All you need is the ip and the root password you configured on install.

I tried to SSH into the box but I was unable to connect. I've also attempted to locate information on the BIOS but I've been unable to locate any information on the company (via Google). I went back and reinstalled the OS just to make sure that the install was good and I have the same problem. I'm kinda at a loss here. I don't think it is the software but I don't know what the problem could be with the keyboard working up until about five seconds after the login prompt pops up on the screen.

When you say the login prompt, are we talking the X login screen, or the mingetty login prompt (i.e. the CLI login presented at runlevel 3 ?).
If it's the X login, try hitting CTRL-ALT-1 to swtich to a non-graphical login.
If you're still stuck and you still think it's the keyboard, you could try booting the machine with neither keyboard nor mouse then reattempt the SSH login from a remote host.
Failing *that* too try booting into rescue mode from a CD and see what happens then.
Once you're in I'd check /var/log/messages (or /mnt/sysimage) for any weirdness.
Will.
