I don't understand why on a fresh centos install, i have systematicaly two dhclients running ? Here it is an extract of /var/log/messages where "ifup" appears : [...] Mar 21 11:43:13 ip-dyn152 sysctl: kernel.sysrq = 0 Mar 21 11:43:13 ip-dyn152 sysctl: kernel.core_uses_pid = 1 Mar 21 11:43:13 ip-dyn152 network: Setting network parameters: succeeded Mar 21 11:43:13 ip-dyn152 network: Bringing up loopback interface: succeeded Mar 21 11:43:13 ip-dyn152 ifup: Mar 21 11:43:13 ip-dyn152 ifup: Determining IP information for eth0...
