Computer Name change

[biggocharley]

I have two machines on my network with the same name. How do I change one of these?

[GeneC]

run this command

Code: Select all

gksudo gedit /etc/hostname

change name, save, exit

[biggocharley]

run this command

Code: Select all

gksudo gedit /etc/hostname

change name, save, exit

Thank you --how simple can it get?

[petersk]

you likely have to change your /etc/hosts file to make sure the localhost has the 'right' name as well. I think there must be something else to change too.

I think the hosts file is changed automatically.

But to make it safe open a terminal and type

Code: Select all

cat /etc/hosts

and post the result here.

I think there is a also a safe(r) way for this, at least for Mint 13 / Mate (I translate the names from german to english):
Goto Control center / Network and select the second tab "General" ("Allgemein")
Click the padlock to unlock the settings (admin's password required)
Change the computer name ("Rechnername") and close the dialog.

Mint automatically updates the above mentioned files /etc/hostname and /etc/hosts for you.

Hope this is more comfortable this way,

run this command

Code: Select all

gksudo gedit /etc/hostname

change name, save, exit

In Linux Mint 19 Cinnamon, when I copy/paste that command, it tells me that "gksudo" does not exist.
Has something about this changed in Mint 19 ?

Thanks.

EDIT 1: Okay...., I replaced gedit with xed and the text editor popped up with the computer name; I changed it and save.
Now, when I open a terminal, my old name remains; however, when I run the /etc/hostname command again, it displays the new name.

EDIT 2: This is a dual-boot machine; can/should Windows and Mint have different names ?

I think in Mint 19 you have to use:

Code: Select all

xed admin:///etc/hostname

if gksudo does not exist.

You mean if something has changed in the over 6 years that this thread has been dead? Good lord, man...

The correct way to change the hostname these days is this:

Code: Select all

hostnamectl set-hostname YOURNEWNAME

Thanks for the current commands to accomplish this.

As for the ancient thread, since the information is no longer relevant, it should be purged from the system so that it would not show up at the top of the list in searches regarding the topic as it only serves to mislead poor misguided souls such as I.

You are welcome. That aside, good luck convincing the volunteer moderators to spend their time verifying 6-year old threads. Just look at the date, that's why it gets printed on every post. Old information can remain relevant, but in particular where system files are involved never use it blindly.
