We have an old version of NSClient++ (version 0.3.9 328) on some of our server that reside in our DMZ. I'm working on updating them to version 4.4.23 however as soon as I update them I receive a socket error.

Does the newer version of NSclient use additional ports that the older version didn't use? ie 12489 It doesn't look like the older client uses this port and I know we don't have it open on the firewall.

When using version 0.3.9 328 I selected both check_nt and check_nrpe (I received a socket error if I didn't check both)



When installing 4.4.23 using the same checks it will not work?


I guess I'm looking for verification that the newer client needs port 12489 open on the firewall to work. Did the older versions require this port to work?

Thanks

Both versions can use 12489 however it depends the types of checks you are running.

If you are checking with 100% NRPE commands then you would just need 5666
check_nt is what uses 12489 (check_nt is what is used in all of the checks using the Windows Server wizard.)

Well that will explain why we are having the problem - thanks for verifying for me
