Ftp-Data connections are then initiated 'the other way around' then normal.
This can be usefull if the ftp client is inside a firewall, and can't
accept new connections coming from the outside.

In case you're running on Solaris...

        9. Normal ftp clients work, Netscape ftp's fail. So, passive
            mode doesn't work.

            Apparantly ftpd needs write permission on ~ftp/dev/tcp in
            order to operate correctly in passive mode (Solaris).
         
            Fix: 

cd ~ftp/dev      
chgrp ftp tcp 
chmod 775 tcp    
        Thanks to Simon Rakov ([email-masked]) for
            this one.

Exactly the same thing happens with the server version for A/UX found at
