I have numerous windows clients that I want to monitor via nagios/nsclient. I've installed the latest nsclient on two win7 x64 and one win2012 r2. Of these one win7 works while the other two machines return
could not complete SSL handshake when a connection is attempted from the nagios machine (libexec/check_nrpe -H hostname -c check_cpu).
What I've tried:
- check passwords - all these systems have identical nsclient.ini files.
- check ports - nmap -P0 client_name returns the same for all (ports 5666 is open)
- run nscp test - non-working systems return
sslv3 alert: unexpected message(win7) or
failed to establish secure connection: no shared cipher(win2012)
I'm stuck trying to figure out what's different between the working and non working windows 7 systems and trying to apply this to a windows 2012 system.
