FTP on SuSE

Ok I give up ... HELP list. I have started ftp and tftp in Yast using Network Services. I have opened port 21 on the firewall and restarted the firewall. All LAN IPs are listed in the FW_TRUSTED_NETS line of SuSEfirewall2. What is left? I can still NOT connect via ftp from any host on the LAN. john
