How to set FQDN in debian?

10.3.1 Hostname

A Debian system sometimes needs to identify itself by name. For this purpose a hostname is maintained by the kernel.

The initscript /etc/init.d/hostname.sh sets the hostname at boot time (using the hostname command) to the name stored in /etc/hostname. This file should contain only the hostname, not a fully qualified domain name.

To print out the current hostname run hostname without an argument.

As stated in the Debian reference, /etc/hostname only contain hostname. How should I go about configuring a FQDN?

Thanks

/etc/hosts is your place. But I must ask what are you setting it for? Your mailserver will have its own config file (/etc/exim/exim.conf for default) as will apache (/etc/apache/httpd.conf) with unique syntax. Here's my /etc/hosts

Code:

[ken:ken](09:26 PM)$ cat /etc/hosts
127.0.0.1       llamakc localhost
xxx.xxx.xxx.xxx llamakc llamakc.org
192.168.0.103   uma
192.168.0.101   polly
128.186.86.136  skoolio
# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

I used xxx.xxx.xxx.xxx b/c I'm on a dynamic IP and it friggin' rotates all the time. I don't actually have that entry in my /etc/hosts though. I included it as an example.

Unless you run your own dns servers you won't need to config it, your FQDN needs to be on your name servers, and your services set up to respond properly.

Do you have a more specific question?

It is because of the following error I get when starting squid:

david:/var/log# squid
FATAL: Could not determine fully qualified hostname. Please set 'visible_hostname'

Squid Cache (Version 2.5.STABLE5): Terminated abnormally.
CPU Usage: 0.010 seconds = 0.000 user + 0.010 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 260
Aborted

Any advice? Thanks

Edit squid's configuration files and specifically the variable it spits out in the logs. Look in /etc.
