yeah.. i found out..
here's what Rackshack support said i should do.
------------------------
Dear Customer;
ftp is installed. There is an error with the server host name when starting ftp.
Changing the hostname on the server is quite simple.
Use telnet (or ssh if you can) and log in to the system as admin. Then use the "su" command to become root. It will prompt you for the root password.
Command: su -l
Change to the /etc directory.
Command: cd /etc
Edit the hosts file and change the hostname there. It should be listed on a line with your IP address first, the full hostname+domainname second, and the hostname by itself third. The easiest editor to use is called "pico" and it provides on screen help so you know what keys to use to save the file, exit, etc.
Command: pico hosts
After that, change to the /etc/sysconfig directory.
Command: cd sysconfig
Edit the network file to change the hostname there, too.
Command: pico network
The final steps depend on what kind of system you have:
Plesk
Use the hostname command to make the new name active.
Command: hostname your.host.name
Now use the Plesk reconfigurator program to tell Plesk to make the new hostname active in all of the different services, like the Apache web server. The reconfigurator program will ask you a few simple questions. It will ask for the email address of the server administrator, the full
hostname+domainname, the domain name by itself, and which IP address to
use for name-based domains. If you are unsure which IP address to use, then simply hit Enter and the system will use your computers main IP address. Finally, answer yes when you are asked whether or not Plesk should restart.
Command: /usr/local/psa/bin/reconfigurator.sh
