FW: FTP and harden_suse

Hi @ll, I'm trying to install a new box for FTP. I did the harden_suse-script and installed a ftpd ( I tried wu.ftpd, proftpd and in.ftpd) and have the following problem: I can connect via ftp from antother box and execute commands like pwd,cd... but commands like ls, get, put yields to 500 Illegal PORT command ftp: bind: Address already in use If I connect from the box itself to the box via ftp everything works fine. Does harden_suse change some settings "deeper" in the system to prevent ftp connections. regards Guido
