Hostname Error

[Mert]

Hello ,

I am having a similar problem also. I checked my hosts file and i dont have anything wrong with the file. Output of /etc/hosts

# 'hosts' file configuration.

127.0.0.1 localhost
::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

Output of /bin/hostname -f :

hostname: Unknown host


but yet again when i use perl ./ispcp-setup i receive the following error

Welcome to ispCP '1.0.0 RC7 OMEGA' Setup Dialog.
This program will set up ispCP OMEGA system on your server.

Next you are asked to enter a "fully qualified hostname" (FQHN).
For more infos read http://en.wikipedia.org/wiki/FQDN.

hostname: Unknown host
ERROR: External command '/bin/hostname -f 1>/tmp/ispcp-setup.hostname' returned '1' status !
