OK, I am a newbie but not to the point the I can’t change the hostname on a Centos server!
Despite this however I am faced with a situation that yes in fact I cannot change it!
The error (if using webmin) is:
Failed to save DNS configuration : Failed to replace /etc/resolv.conf with /etc/resolv.conf.webmintmp.17474 : Operation not permitted
I then attempted to change the file /etc/sysconfig/network however the system will not allow me (logged in as root):
Inside VI I see this >> “network” E212: Can’t open file for writing
I then have to quit vi as it will not allow me to save.
Permissions of file:
-rw-r–r-- 1 root root 61 Mar 3 2010 network
It appears as if something is blocking every write attempt to the file but I don’t know what!
If I had to guess, I would guess that one or more of those files are marked as “immutable” (which prevents even root from changing them). Or, if you’re using a VPS, it’s possible your provider somehow made them read-only.
What is the output of these 3 commands:
mount
lsattr /etc/resolv.conf
lsattr /etc/sysconfig/network
It’s a dedicated server so I should be able to do everything when logged in root.
Commands:
mount
/dev/hda3 on / type ext3 (rw,usrquota,grpquota)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
/dev/hdc1 on /backup type ext3 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
