Hi, I'm using Zope 2.8.6 with Python 2.3.5 and have found that when I FTP into zope, I am unable to list the contents of the directory I am in. It seems that logging in is no problem. Could this be a problem with my firewall? Has anyone seen this before? We are using port 8021 rather than the usual port 21. Could this be the issue? Any help is appreciated. Thanks! Dan

Try to FTP in passive mode. FTP usually requires *two* ports to be open 8021 (standard) and one that can't be determined usually (by the end-user). -aj

Yep. But IIRC, passive mode won't help if the firewall is doing NAT. I had the same problem - login seems to work, ls fails. Blame FTP. It just wasn't designed for a world that includes NAT. If you can arrange to use WebDAV instead, that should work fine. -- Paul Winkler http://www.slinkp.com

FTP was designed much earlier before NAT appeared in the world :-)

on suse you can configure the firewall to allow negotiating for the second port. I do not remember the parameter but could look it up if you wish. robert
