Maybe you can try removing IPADDR and NETMASK and adding: IPV6INIT=yes IPV6ADDR=::1 The complete documentation for the ifcfg files is in : /usr/share/doc/initscripts-*/sysconfig.txt There is a log of other documentation in this file as well .. I would just search for ifcfg once inside the file. Hope this helps, Barry
