[wellylug] Advice on FTP access from Debian.

[Peter Davenport]

I use Debian Woody on machines on a LAN with connection to the outside 
network via a dial up line. This connection is managed by a 
router/firewall/NAT using Freesco.
To update some components, I went to use FTP to an outside server and it 
failed. On closer investigation, my local machine will interact correctly 
with local servers but not with outside ones. It will connect to a remote 
FTP server, get a request for user and password and complete that. I can 
issue 'cd' commands and it will work, but 'ls' and 'get' commands fail 
with messages about 'invalid PORT command'. I had thougth this was to do 
with the data channel not getting through the firewall/NAT, but my son 
said he could use FTP to outside servers using Windows and Dos. This I 
confirmed, so it must be somthing within my Debian machine setup.
It is now embarrassing to be told by my son that his Windows machine will 
do this while Linux will not and so it needs to be fixed. Could anyone 
offer guidance on what to look for?
