 Posted: Fri May 02, 2003 9:33 pm Post subject: Missing Network Name |
 |
|
Somewhere along the way I seem to have misplaced my network name. Upon finishing booting, I am greeted with "This is lucia.(none) (Linux i686 2.4.20-gaming-r3)"
The hostname file contains "lucia.pentagulia.net" and nothing else.
I've compared it to other machines on my network and can find no obvious place the network name should be but isn't.
Anyone know what I am missing?
Thank you! |

| This seems to be the name of the hosts at the time of making the kernel. Rebuilt your kernel if you want the current host name to be shown. |

I have the same problem, it does not seem to affect anything. My machine is running a Samba print server just fine. The only problem is is my domain name is listed as .(none) 
I'm also using gaming-sources kernel.

| And you both have a /etc/hostname containing a FQHN? |

My /etc/hostname has
My /etc/hosts has
| Code: |
127.0.0.1 localhost
192.168.1.101 grev.speakeasy.net grev
|
I never had a problem seeing my domain name till I re-install Gentoo this week.

Maybe this is an issue of the gaming-sources!?!
Is the hostname only incorrect when the kernel boots or is it even later when the system's up and running? |

I have report this to bug.gentoo.org

Try
| Code: | | domainname <yourdomain> |
See the man page of domainname. |

| Note that domainname is only responsible for the NIS/YP-domainname. If you do not run NIS/YP, don't care about what domainname says. All that normally counts is the output of hostname (or hostname -f). |

hostname -f does show
grev.speakeasy.net
So it is probably just a display bug during boot, and has no real effect on the system.

I have a small program lying around here that sets the domainname based on your FQDN, so you could add it to /etc/conf.d/local.start and never worry about your domainname. Just copy+paste the code below and compile it with "gcc -o setdomainname setdomainname.c"
