FTP server hangs on ls, put, get, ...
Greetings. I've got a Zope installation that doesn't seem to want to do FTP. I can open a FTP connection to the server -- the authentication dialog goes okay -- and I can cd and pwd, but if I try to transfer any data (ls, put, get, etc.), the server seems to hang and eventually time out, terminating the connection. I can successfully FTP to other Zope servers. I've restarted Zope. I've tried connecting from several different client machines, and from different FTP client programs, and I get the same behavior each time. So, it seems to be something about that particular server (Zope 2.6.1 on Red Hat Linux 8). Anybody got any insightful advice or suggestions?

Is the server behind a firewall? I've never been able to get ftp working through a firewall. -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's SMELLY HYDROXY MAILMAN! (random hero from isometric.spaceninja.com)

FTP works with two ports: a control port and a data port. Apparently, your firewall blocks the data port. Some old post explains how to set up firewall rules to allow both control and data ports. Please search the mailing list archive. Dieter
