Help with SuSE Firewall2. Open Firewall for SMTP?
Firewall gurus ... I have been through the docs and I will confess I am looking for a faster solution. Please excuse what looks like a slack waste of bandwidth. I have got much help from this list and usually a point in the correct direction from here is enough. The issue ... I have a new SuSE 9.1 Pro installation. I have not done any configuration with Yast on the Firewall. To the best of my knowledge the Firewall is in place with only ssh access in. This is good. I now want to open my SMTP port 25. The is the only opening I will need at this time. Can some one send me the correct /etc/sysconfig/SuSEfirewall2 entry? What do I need to do after I create the correct entry with respect to restarting the Firewall with the new config? I am fairly sure I know what to do with Postfix after the port is open. All comments welcome. Am I missing anything else? Thank you list friends. john ------------------------------------ John N.

If you haven't done any configuration and you can still ssh in, then the firewall isn't running. The default is to block everything, including ssh
Can some one send me the correct /etc/sysconfig/SuSEfirewall2 entry?
Find the line with FW_SERVICES_EXT_TCP and put FW_SERVICES_EXT_TCP="ssh smtp"
What do I need to do after I create the correct entry with respect to restarting the Firewall with the new config?
rcSuSEfirewall2 start (or restart, on the off chance that it actually is currently running) You can also do all of this from YaST, in the security&users->firewall section. You can't do everything there, but just opening for services is very simple through that
