Linux hostname is always localhost.localdomain

Reported by: Ageless Assigned to: davea
Priority: Major Milestone: Undetermined
Component: Client - Daemon Version:
Keywords: linux hostname Cc:

Description

Both in client_state.xml and on any project we connect to with (at least) a 5.10 client, the computername is always shown as localhost.localdomain, never as the hostname of the computer.

When I open a terminal window and do hostname -a it shows my hostname correctly. Not with BOINC though.

I understand from Rom that BOINC calls a POSIXs api to get the local computer name, but that doesn't seem to work. Can't BOINC just read /etc/hostname ? Or use gethostname (see also gethostname(2) ?

It might help to note which distro.

It does work on my install of Ubuntu Feisty Fawn.

It does not work on fedora 6 & 7. I have been able change the client_state.xml file with something more appropriate and it stays. But neither host has updated to the actual hostname of the hosts in question.

Does seem to work OK on my openSUSE 10.2 64-bit (both KDE and Gnome) using 5.10.8 32-bit Boinc.

I've seen other complaints about the same thing though, so not just a one-off. Something to do with the way 127.0.0.1 has been set up on the PC?

Replying to MikeMarsUK:

I think so. When checking /etc/hosts the first line shows: 127.0.0.1 localhost.localdomain localhost Ruba Ruba.domain.dom

The last part is my computer name, of course. Yet it reads the first part all the time. And I am not so sure if I can just change it there, without breaking my Mepis 6.5.02 (based on Ubuntu, KDE).

Here's mine. It's different to what I expected (this is the first time I've looked at it on a linux system), note that the machine name (linux-rcud.site) is against the machine's local IP (192.168.1.64, I set it up to be static), rather than against localhost. 

mike@linux-rcud:/etc> more hosts

# IP-Address  Full-Qualified-Hostname  Short-Hostname

127.0.0.1       localhost

# special IPv6 addresses

fe00::0         ipv6-localnet

Seems BOINC uses the 1st name in the hosts file. This example should have BOINC report back it's name as COMPUTER

{{{$ cat /etc/hosts 127.0.0.1 COMPUTER localhost computer.mynetwork computer}}}
