Hello, I been trying to configure SuSefirewall2 and pure-ftpd to work together. When I have the firewall off I can ftp to the server and everything works as plan. When I activate SuSefirewall2 I can ftp in and authenticate but when I do any commands, say for example cd or ls, it says: Remote system type is UNIX. Using binary mode to transfer files. ftp> ls 229 Extended Passive mode OK (|||11162| At this point it freezes and I have to do a ctrl+c to exit the activity. Any thoughts on why this is happening. Thanks ahead of time. -- Bob Barish B.M.T Solutions http://www.bmtsolutions.com 4:10pm up 1 day, 1:14, 5 users, load average: 0.00, 0.01, 0.02

It's happening because in passive mode you need to open up high ports on the server. In the firewall config file set FW_ALLOW_INCOMING_HIGHPORTS_TCP to "yes" regards Anders -- `When I use a word,' Humpty Dumpty said in rather a scornful tone, `it means just what I choose it to mean -- neither more nor less.'

Thank you very much for the help guys. I manually went in and change the config file in /etc/sysconfig/SuSEfirewall2. I put FW_ALLOW_INCOMING_HIGHPORTS_TCP ="yes" as Anders suggested and it is working great. I have one question if you do not mind where can I get an explanation or how passive mode works and why it needs the high ports Thanks again! -- Bob Barish B.M.T Solutions http://www.bmtsolutions.com 5:33pm up 1 day, 2:37, 5 users, load average: 0.04, 0.01, 0.00

This site has a brief decription. It also links to the rfc that defines the file transfer protocol. http://slacksite.com/other/ftp.html -- `When I use a word,' Humpty Dumpty said in rather a scornful tone, `it means just what I choose it to mean -- neither more nor less.'
