 Posted: Tue Jan 11, 2005 8:49 pm Post subject: Problems setting my hostname |
 |
|
Hi there, I have some slight problems with this. I followed the guide at https://forums.gentoo.org/viewtopic.php?t=276942.
I get my IP for my server via dhcp. Here is my setup:
I use dyndns for my ip resolution, and the name is mdke.mine.nu
/etc/hosts:
| Code: |
127.0.0.1 euthathios.mdke.mine.nu euthathios localhost |
/etc/hostname:
/etc/domainname:
So everything is as in the guide. I have rebooted.
However I get this error with one of the commands that you specified to check the setup:
| Code: |
matt@eustathios matt $ hostname
eustathios
matt@eustathios matt $ hostname --fqdn
hostname: Unknown host |
Further, Proftpd and tetrix fail to start, the errors being, respectively:
| Code: |
root@eustathios matt # /etc/init.d/tetrix start
* Starting TetriNET Server...
Hostname self-lookup failed. [ !! ] |
| Code: |
root@eustathios matt # /etc/init.d/proftpd start
* Starting proftpd...
- getaddrinfo 'eustathios' error: Name or service not known
- warning: unable to determine IP address of 'eustathios'
- error: no valid servers configured
- Fatal: error processing configuration file '/etc/proftpd/proftpd.conf [ !! ] |
I would appreciate some help with this!! I've never got my hostname/hosts/domainname set up exactly right on this network...
Thanks in advance!! Matt |

Have you created dnsdomainname? |

Hi, thanks for your reply!!
| Code: | root@eustathios matt # cat /etc/dnsdomainname
mdke.mine.nu |
I also sym linked nisdomainname to this, and made sure the service was running and started upon boot.

Having said this, there is obviously something wrong with it, because:
| Code: | matt@eustathios matt $ dnsdomainname
dnsdomainname: Unknown host |
As i mentioned, mdke.mine.nu is the name I use with dyndns to resolve my IP. Does anyone have any suggestions?
Thanks again. M |

here is mine | Code: | # /etc/hosts: This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server. Just add the names, addresses
# and any aliases to this file...
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/hosts,v 1.8 2003/08/04 20:12:25 azarah Exp $
#

192.168.1.97 abbottdavid.localnetwork abbottdavid
# IPV6 versions of localhost and co

fe00::0 ip6-localnet

/etc/hostname and /etc/domainname are deprecieated. Use /etc/conf.d/hostname and /etc/conf.d/domainname.
Note: Using these will not cause the problem, I am just stating that they are deprecieated.

Do you have any references for that? I haven't found any information on it, neither in my files (they don't exist) nor in the documentation.

Stop using /etc/dnsdomainname and use /etc/conf.d/domainname
same with domain, clock and keymaps. |
Took a while to find this but thats where it came from.. surprised you haven't seen the messages.

dnsdomainname is sym linked to hostname on Fedora Core 14.
The use od dnsmasq with the -s option means that the /etc/hosts file
and the /etc/resolv.conf file are both brought into play.
192.168.7.2 mrepo cobbler.localdomain
will fail - WHY? because the usual semantics of DNS are used
IP address followed by FQDN followed by alias(s).
Which means that 192.168.7.2 is the IP address it might find inside /etc/hosts
mrepo is supposed to be the FQDN - but how can it be - really.
The dnsmasq application will not complain about this entry.
The hostname command comes back with the right name iff
the /etc/sysconfig/network entry has the correct name and they
agree that /etc/hosts has the same info - at least for that hostname.
So the dnsdomainname is trying to pull apart mrepo into its
short hostname and dnsdomainname parts. This is not possible
because there is no DOT FQDN available.
What should happen is the entry should be re-ordered to
192.168.7.2 cobbler.localdomain mrepo
Now Cobbler is happy because it has a dnsmasq entry for mrepo
and dnsdomainname is happy because it splits the cobbler.localdomain
(FQDN) up with the DOT syntax as
short hostname: cobbler
dnsdomainname: localdomain
