we configure our root server (come from hoster with another hostname) with new hostnmae. We also give it in hostname, HOSTNAME, etc. on suse. So all day, when the dhcp is update a new signal, the server run back to old hostname in all services (we also show it, when we log in via ssh).

So i flush it with hostname XXX.XXXX.XXX and then al working, the message in ftp connections is "FTP is not configuerd for this server". When we give the new hostname, all working fine, some resolutions?
