Description Jonathan Kamens 2012-10-03 07:07:06 EDT
After upgrading this morning to dhclient-4.2.4-1.P2.fc16 and rebooting, dhclient obtained and logged to /var/log/messages an IP address for eth0 but didn't configure the address onto the device. I had to do "ifconfig eth0 <addr> netmask" and then "route add default dev eth0 gw <gateway-from-leases-file>" to get my network up and running. Downgrading to the older dhclient, dhcp-libs and dhcp-client fixes the problem.

I have SELinux enabled, but there's nothing in /var/log/audit/audit.log to suggest an SELinux issue.

Comment 4 Chris C. Chen 2012-10-04 03:48:07 EDT
It looks like /sbin/dhclient hardcoded to execve /usr/sbin/dhclient-script, while the script is actually in /sbin/dhclient-script.  A sym-link to the actual file fixed my fc16.


>Oct  3 04:57:55 localhost dhclient[1152]: execve (/usr/sbin/dhclient-script, ...): No such file or directory
>Oct  3 04:57:55 localhost dhclient[1151]: DHCPREQUEST on eth0 to port 67
