Firewall in SuSe Linux

How to check if Firewall is running or not?
Ans: You have to check if the Firewall service is running or not.

# /sbin/rcSuSEfirewall2 status
Checking the status of SuSEfirewall2 running

It is tellling you that Firewall is running. Firewall blocks telnet/ssh/scp by default.
You can stop firewall by following command

# /sbin/rcSuSEfirewall2 stop

Now try to telnet/ssh/scp into the server remotely, you should be able to make connection


You can use 'chkconfig' command to check the service startup status after reboot.

# chkconfig --list|grep firewall
SuSEfirewall2_init 0:off 1:off 2:off 3:off 4:off 5:off 6:off
SuSEfirewall2_setup 0:off 1:off 2:off 3:off 4:off 5:off 6:off

In my case, it says that firewall will not start automatically after next reboot as it's has off status in every terminal (1 thru' 5)


If you are not feeling comfortable playing with command line, you can use YAST for the firewall management. 'Firewall' is located in 'Security and Users' option.

Have a good one!
