Has anyone heard of anything like this, and if so what did you do?
The machine is a Compaq deskpro SFF, PIII. It is running Mandriva. The IP address is manually assigned, and its not connected to the Net, this is just for internal printing.
You plug the machine in, boot up, and everything is fine. You can reach other addresses, print on a network printer, log into the network printers admin over the web browser (the printer itself, not CUPS on localhost). You can do file transfers from other machines.
You then turn off using the gnome power control. System goes down, screen goes blank. Little light on back of network card goes out. Reboot, and network is unavailable. Do ifup eth0, comes up, however ping doesn't work in either direction and the other machines are not there. Connection refused is the message. The little light is still off.
After much headscratching, shut down, turn off at mains, wait 20 secs, turn back on at mains. Little light comes back on, boot up, everything works....
What obvious thing am I missing? I would expect that it should go off at shutdown, and go on at bootup.
The only other oddity is that Mandriva seems to think there are two network interfaces, one the card which really is in it, and another interface called sit0 or something like this. You can delete this without it affecting the eth0. I don't understand where this is coming from, if it matters, or what to do about it.
Any suggestions gratefully received.
