[CentOS] DHCP without network access

[Maciej Żenczykowski]

Actually the DHCP client on the box was setup during installation (pretty 
much the default there).  As for the server, that was done by installing 
and enabling the server (via "yum install dhcpd" and "chkconfig ... dhcpd 
on" and "/etc/init.d/dhcpd restart") with a hand edited /etc/dhcpd.conf 
configuration file.

Basically the problem was that I unloaded the kernel module responsible 
for the network interface on the DHCP server and then loaded a different 
once and forgot to restart applicable services (DHCP) that bind direct to 
devices - thus leading to no DHCP on the reloaded network interface for a 
little over quarter of a day (until I restarted the DHCP server). 
Obviously the server issue was an oops on my part, but the question is why 
doesn't the client recover gracefully....

Cheers,
MaZe.

How did you set it up? Gui? Cli? I have CentOS 2.1, but imagine the same
setup. Have tried wired and wireless and have had no connection. Tony
