Change Linux Hostname

Linux and Unix-Like Linux

Hi Good Day!

I have a fedora 8 installed and I wan't to change its hostname since the default hostname is "localhost.localdomain". I wanna change it to something different. Please some one advice what to do. Do I have to change the entry in "/etc/hosts" or there's other way to do it?

You need to change the hostname in both /etc/hosts and /etc/sysconfig/network.

I had already changed the entry on both location. I still have one more question?

Do I really have to include the domain in the entry?

Please bear with me, I'm still a newbie on linux. BTW, I am using DHCP, will this affect.

I mean I had not included a domain on /etc/hosts. Does this affect my network functionality or my network functionality will fail?

No, the full doman name is not required.

Thanks MacMonster.

Mac...

Why is it when I'm on windows I could not ping using the newly assigned hostname?

I can ping the IP Address. Do I need to assign a static ip for my linux?

You need to add the hostname and IP address either to the hosts file on your Windows system (usually C:\Windows\System32\Drivers\Etc\Hosts) or to your DNS server, if you have one.

u can also set the hostname via sysctl -

 sysctl -w kernel.hostname=hostname_u_want
