Rookie broke firewall
 

I have Fedora 4 loaded.

I added this line to the firewall (Desktop\System Settings\Security Level): 5901:tcp

I closed the firewall and retried VNCing into box. No luck so I restarted linux. Still no luck, I tried to access the firewall again. It opens for 2 seconds and closes.

When I run this: system-config-securitylevel --> at the command prompt, I get this:

Traceback (most recent call last):
File "usr/share/system-config-securitylevel/system-config-securitylevel.py" line 18, in ? app.stand_alone()
File "usr/share/system-config-securitylevel/secruitylevel.py" line 453, in stand_alone self readFile()
File "usr/share/system-config-securitylevel/secruitylevel.py", line 353, in readFile protoname=socket.getservbyport(int(service), protocl)
socket.error: port/proto not found


Any ideas, I cant get VNC to work or edit the firewall

Thanks

That syntax looks ok, so it might be some kind of bug with the firewall GUI. Try using the command line instead:

Open a new terminal
Become root with su -
Enter root password when prompted
Enter the following:
iptables -I INPUT -p tcp --dport 5901 -j ACCEPT

Test out your VNC
If it works, then make changes permanent with:
service iptables save
