I am trying to set up a SAP System on SUSE Enterprise, but I'm having trouble connecting to the server. I added multiple ports to the public section of the firewall and with most of them I am able to reach the server through that port.

firewall-cmd --zone=public --add-port=8000/tcp
firewall-cmd --runtime-to-permanent
firewall-cmd --reload

From the outside I am now able to the test the connection to my server, for example from a windows client succesfully via

test-connection -computername [IPADDRESS] -port 8000

But for the port 3200 this doesnt work.

When I use nmap I get the following result:

nmap -p 3200 [IPADDRESS]


3200/tcp  closed  tick-port

I already tried commenting the ports out from /etc/services but the result stays the same.

How can I "open" this port?

    is something listening on port 3200? netstat -putan

  • if you do lsof -ni :3200 is anything running on that port. Can you connect to port 3200 locally

  • netstat -putan is not working for, can't get netstat to run on SUSE.

  • Well in that case, nothing is listening on that port. So that's why you cannot access it from the outside. Start the service which should listen on port 3200 and try again

Found the missing service. When I started it, port was listened to. Thanks for all the help!

    This answer seems to lack information about how the service was identified and started.
