Renaming computer

[Odyssey]

Just installed Ubuntu 8.04 on a new computer with a 160GB hdd and in the setup thought that I had named the compter

U8.04-160GB

but in the terminal window, it shows as

U8

Did the period terminate the name?

I want to rename it and assuming that the above answer is yes, to

U804-160GB

or if the hyphen is also going to cause a problem, then

U804160GB

How does one rename their computer?

[silver]

one way that should work

hostname U804160GB

(as root)

Hyphens/dashes are OK but I don't think you can used dots. sudo gedit /etc/hostnameJust checked and changed mine from P4-Intrepid to P4-810

I opened a terminal and used:

sudo hostname U804160GB

and nothing changed,

then used:

sudo gedit /etc/hostname

which opened a text editor with U8 as text in it, which I changed to U804160GB

and saved it, then opened a terminal window and still U8.

Am I missing something basic? Do I need to restart (shades of Windoze)?

[Odyssey]

Restarting did the trick! Thanks to both of you.

Not the end of the story it seems.

I ran the shell command:

sudo lshw

on the computer that I recently renamed and got the message:

Unable to resolve host.

What's that all about?

Strange - I renamed this P4 Ubuntu 810 system and everything still works fine. You could ask on Ubuntu Forums. All I can think of is to check the Hosts tab in the network settings.

the hostname of the box should typically resolve to an IP address - in /etc/hosts - suprised sudo wants to check that but it might be a security thing I guess

mine has at the top

127.0.0.1 localhost.localdomain localhost
172.25.99.204 computer_name
