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 host < NOT 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

Another thing about this, postfix fails on startup:
Feb 9 00:49:57 x800 postfix[1387]: warning: valid_hostname: invalid character 13(decimal): x800.mydomain.local? Feb 9 00:49:57 x800 postfix[1387]: fatal: unable to use my own hostname Feb 9 00:49:59 x800 postfix/sendmail[1471]: warning: valid_hostname: invalid character 13(decimal): x800.mydomain.local? Feb 9 00:49:59 x800 postfix/sendmail[1471]: fatal: unable to use my own hostname
Because some CentOS system file is corrupted?
After setting "hostname x800.mydomain.local" postfix starts normally.
