[K12OSN] Help? Programs not Running?

[Jim Kinney]

double check that the bridge device ltspbr0 actually exists (check lsmod -
check ifconfig and /etc/sysconfig/network_scripts/ifcfg-* )
Double check that ip_forwarding is still OK

watch the dhcpd log with tail -f  while things are trying to connect and
see if the server "sees" anything.

double check the firewall allows incoming dhcp requests.

HOWEVER: I'm assuming the clients are regular LTSP clients so they already
get dhcp during their PXE boot phase - thus dhcp IS working.

run back through the /var/log/yum.log and see what was updated.
