hi all,
Was wondering if anyone is running Centos on a CF card slot. It installed OK , it boots ok, but after a while it is no longer on the network.
After power cycling there is nothing in the /var/log/messages as to a crash etc...
I ran a USB thumb drive 8G on this same PC and it seems to continue to work. Just STICKS out a few inches. Not the best look.
Any pointers on how to find out what it doesnt like? Any pointers on running from a CF card.
I have done the straight 686 install - I do add asterisk to the box.

Hook a serial console to the system to see if there is anything that the console prints out that indicates what caused the failure.
What do you mean by a CF card slot? Is it a USB->CF adapter? If your going the CF route I'd suggest a [P|S]ATA->CF adapter instead of a USB one.

when its 'not on the network', what is the state of the networking layers?
# ifconfig -a # netstat -rnetc ?
When I try do do anything on the console I get no response. network doesnt respond to a ping either.
So I just reboot. thought maybe there would be something in the log file saying why the lock up but there isnt.

It's pretty rare for there to be log entries on the box that point to why it crashed or locked up, at least in my experience, hence the need for a serial console.

Tailing dmesg might show something. Might not either but it's an easy thing to try.

dmesg isn't a file, its a program thats dumping the kernel message buffer. how do you live 'tail' it?

when I do that it lists the usual 10 lines from tail, then exits, -f or not.

I didn't quite mean tailing the dmesg program. What you need to tail (IIRC) is /proc/kmsg.

dmesg|tail you knew that, did you ;-)
Also, you can do tail /var/log/dmesg but the result is the last buffer.

if this CF card slot is emulating a IDE device (that IS what CF cards do on PCMCIA, after all), I'd try disabling IDE DMA and see if that stabilizes it.
