[CentOS] fqdn hostname fails after reboot
Hi, I have several machines running CentOS 6.2 and a strange problem with the hostname of one machine... After every reboot it loses the fqdn hostname. Here is my confguration: ifconfig | grep inet addr inet addr:10.0.0.12 Bcast:10.0.0.255 Mask:255.255.255.0 inet addr:127.0.0.1 Mask:255.0.0.0 /etc/sysconfig/network NETWORKING=yes HOSTNAME=x800.mydomain.local GATEWAY=10.0.0.1 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.12 x800.mydomain.local x800 ... after a reboot: hostname x800.mydomain.local OK hostname -f hostname: Unknown hostNOT OK dnsdomainname dnsdomainname: Unknown host NOT OK If I set the hostname manually: hostname x800.mydomain.local hostname -f x800.mydomain.local OK dnsdomainname mydomain.local OK Everything is okay ... Something I've never experienced before. Does anyone have an idea? thx -- Chris ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
