add port to firewall?

[bentaylor]

I can't connect to my ftp server (vsftpd) and I suspect it's due to firewall issues.

Does anybody know if it's possible to add an allowed port to the firewall via command line (so i can do it via ssh)? I know it's not my router as port 21 is allowed through that and forwarded to my box as it's worked since I've done anything to the router (on a previous install attempt).
When i set it my current installation I added 'TFTP' to the list of allowed things to the firewall but I strongly suspect this hasn't added port 21 which is what vsftpd needs.
My sshd and httpd servers seem to work fine.

So how can I list the ports that my linux firewall is allowing through, and if necessary add 21 to them?

SUSE firewall is managed through YaST. I think you can edit the /etc/sysconfig entries and rerun sysconfig but the easiest thing to do is run yast. It works at command line level through ncurses anyway so even if you don't have X running you can work on it.

OK, cheers - is there a way to turn it off from the command line just to see ifit is that, then i can mess with it in detail if it is?

oh, I turned it off ok...
it STILL only logs in every third try though!
what is this shoddiness all about?
