i have two machine, both are same version rhel6.4
serverB, installed the server by default hostname, localhost.localdomain
hostname -s
localhost
hostname
localhost.localdomain
can i change the hostname without edit /etc/sysconfig/network
because my serverA, i change the hostname during installation.
/etc/sysconfig/network is showing hostname=localhost.localdomain, but when i type hostname, i
I'm making some large-scale system hostname changes and this got me thinking...
I used hostname NEWHOSTNAME and set a new hostname. Then I restarted, and tried accessing the internet and nothing happened.
I recently began having issues with my Arch box not allowing connections based on hostname. Not sure whats going on I can SSH into the box, view the webserver, ftp, etc assuming I am using the IP address. If I use the hostname, nothing works.I can nslookup from a Windows machine and see the IP is resolved..
I have a virtual server running Debian Squeeze. I can change the hostname by running the hostname new.host.name command or by editing /etc/hostname and then running /etc/init.d/hostname.sh, but after a reboot the hostname will be reset to the preconfigured hostname chosen by the server-hoster.
On CentOS (5.x) I have a VPS that has hostname set to "olddomain.com", at least this is the domain I am getting when typing "hostname" command.
I want to change it to 'localhost.localdomain' because I think it is more generic and reliable.
localhost.localdomain already exists in these files: /etc/sysconfig/network AND /etc/hosts
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain

I tried to change my hostname according to this guide for Debian based system:
I edited /etc/hostname file
run /etc/init.d/hostname start
Though there are errors. Always when I write a sudo command it tells me it can't recognize hostname. After I restarted the system, graphical environment wasn't working, startx command wasn't successful.
Before the switch to systemd, I was able to ssh between my two machines via user@hostname but now I get a "could not resolve hostname" error and have to use the IP address instead.
I've already tried changing the hostname by editing both:
/etc/hostname
/etc/hosts
However when I try to use sudo it doesn't work. I have to restart the computer to make sudo work again.
