[Xymon] How to restore a check that was previously disabled

Hi,

I am using xymon 4.3.12. I previously had the ports check disabled in the hosts.cfg file using the defaults like:

0.0.0.0 .default. # NOCOLUMNS=ports

I have then subsequently removed this NOCOLUMNS entry for ports and have defined a check for a couple of servers straight from the example in the man page to check for SSH port being open.

The check has not reappeared in the xymon webpage and was wondering if there was anything special I need to do to "reactivate" it so xymon is aware that it should appear again on the webpage?

Thanks

Alex
