[olug] vsftpd Suse 9.0

Sat Apr 3 23:22:51 UTC 2004

You can check to see if your firewall ( or router ) is blocking ftp by 
going to an online scanner like
http://www.grc.com and going to their "Shields Up" scanner page.

If you're running the SuSE Firewall you can go into YaST2 and configure 
it ( under Security and Users ). I didn't see an option for allow ftp 
specifically but you can add that in the field provided at the bottom.
