No reboot needed as root type; service network restart

Not enough information to make a reaonable guess at. But it is not normal for the cable to be disconnected by hand. Could be a faulty network card (bad firmware) or a faulty hub or...........

If the network restart command restores the network connecti then the fault maybe in the firmware for the network card or in the system BIOS (built-in network).

hi Lenard, thanks for your reply,
i disconnect the cable by hand only for testing : i discavred the prob when the switch is powered off then after i power on the switch, the lan card on the server is off.

it is an integrated lan card on an HP proliant 370 G4.

i will try with another PCI lan card ...

thanks again for help.

Sorry but Linux is not Windows and does not poll hardware every few seconds looking for something new or changed. The only way to restart the network interface short of rebooting is to use the command I already provided.

Note: This auto re-starting of the interface for some network interfaces (USB and PCMCIA/CARDBUS come to mind) but not with RedHat ES3. The hardware layers needed (UDEV, USB, HOTPLUG and others) are not backported to the 2.4 kernels that Red Hat supplies.
