check_ssmtp (check_tcp) SSL Errors

[Todd Barbera]

Why not use check_smtp instead? I don't think port 25 is an SSL port within
sendmail, although I'm no sendmail expert. I use check_smtp in my
configuration and it works fine.

Hi everyone,

 

I am up to adding our mail servers to our nagios monitoring list and hit a
roadblock with monitoring sendmail.  I have tried using the following
command at the cmdline:

 

./check_ssmtp -w 5 -c 10 -H mail -p 25

 

But I get the following error message:

CRITICAL - Cannot make  SSL connection 29889:error:140770FC:SSL
Routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:475:

 

I can connect to mail from the Nagios monitor via port 25 and I have also
added the host to the sendmail access file.  Apparently I am missing
something, ideas?

 

BTW, we have our mail servers clustered so we need to monitor this port vs.
the actually service since the sendmail service is running on the active
node, thus we cannot use check_nrpe.

 

Thoughts anyone?
