Re: How do i change hostname?

[P. Larry Nelson]

Arnav,

Before spending your money, you might just try any number of online
resources.  Google is your friend.

A few sites that come to mind immediately are:
 - The Linux Documentation Project
   (http://tldp.org/guides.html)

 - The Linux System Administrator's Guide from the same site as above.
   (http://tldp.org/LDP/sag/html/index.html)

And since you're running SL6.x, which is really Red Hat Enterprise 6,
Red Hat has a plethora of documentation.  See the following, in particular:
https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/index.html

Re: How do i change hostname?

If you don't want to reboot your computer, then become root and type this:
[arnav@dhcppc1 ~]$ hostname lappy

then exit your terminal and open a new terminal.

The actual file to change your hostname is:
[arnav@dhcppc1 ~]$ vi /etc/sysconfig/network

If you edited file /etc/sysconfig/network, then you need to reboot your
computer.

I'd have just copied and pasted the output of the ls command personally.

I forgot that most people don't kill NetworkManager out of habit; you can stick
