How to enable synergy 24800 (or some other port) through firewalld
- by ndasusers
After upgrading to Fedora 18, Synergy, the keyboard sharing system was blocked by default. The culprit was firewalld, which happily ignored my previous settings made in the Fedora GUI, backed by iptables.
~]$ ps aux | grep firewall
root 3222 0.0 1.2 22364 12336 ? Ss 18:17 0:00 /usr/bin/python /usr/sbin/firewalld --nofork
david 3783 0.0 0.0 4788 808 pts/0 S+ 20:08 0:00 grep --color=auto firewall
~]$
Ok, so how to get around this?
I did sudo killall firealld for several weeks, but that got annoying every time I rebooted. It was time to look for some clues. There were several one liners, but they did not work for me. They kept spitting out the help text. For example:
~]$ sudo firewall-cmd --zone=internal --add --port=24800/tcp
[sudo] password for auser:
option --add not a unique prefix
Also, posts that clamied this command worked also stated it was temporary, unable to survive a reboot. I ended up adding a file to the config directory to be loaded in on boot.
Would anyone be able to have a look at that and see if I missed something? Though synergy works, when I run the list command, I get no result:
~]$ sudo firewall-cmd --zone=internal --list-services
ipp-client mdns dhcpv6-client ssh samba-client
~]$ sudo firewall-cmd --zone=internal --list-ports
~]$
