Since you said the server doesn't support passive mode and is located
outside of your corporate network, it sounds like a firewall issue.
I would normally suggest checking if there is an FTP proxy you can use.
However, you said the code worked on the Windows machine but not the
SuSE machine.  In that case, it sounds like the SuSE machine has its
own firewall rules installed.  Check iptables (/sbin/iptables -L -n)
to verify.
