Hello
Depends on which FTP server is/was installed. Check with:
rpm -qa | grep ftp
And post up what you get. Be sure the FTP server is running:
/etc/init.d/FTPSERVER start
Where FTPSERVER is the name of the server installed (which should be revealed from my above command).
1. Depends on what server.
2. useradd or userdrake, or fire up an X session and use a graphical tool.
3. Too many possibilities, but check to see the server is running first.
And, as a side note, how do you know it's not because of Firewall, Mandrake comes with a built in Firewall...
Cool
