[Solved] Hostname changes to dhcppc2

[niyumard]

Hi, I've set my hostname as per handbook's guidance:

Code: Select all

cat /etc/hostname
computerpc

but running hostname returns: dhcppc2

When I first boot my computer, my host name is shown correctly but after a while (for example by logging in or entering a wrong password), it just changes to dhcppc2
What should I do?

Welcome to gentoo forum.

You are sure that /etc/hostname is correct location?
In handbook we talk about /etc/conf.d/hostaname.

Oh right,
I'd set that place actually, and today I saw a strange line added to it:

Code: Select all

# Set to the hostname of this machine
hostname="computerpc"
is<80>kbge<80>kb<80>kbcomputerpc^[:wq^M

I removed the other line and will update this message if this changes anything.

Update: removing the line didn't change anything, hostname still returns dhcppc2

I'd guess that your dhcp server is setting it.

Yep, this just reminded me that I'm using connman and ArchWiki has warned about it changing the host name.
Fixed it by the way suggested in ArchWiki's article:

Thank you!
