check_ssmtp (check_tcp) SSL Errors

[Todd Barbera]

I have 1.4.1 of the plugins and it was included in the distribution. I
checked the REQUIREMENTS file and didn't see any prereqs for getting it to
compile and install. I do use check_tcp to verify that our Meeting Maker
software is listening on the proper port, so that's probably a valid option.

Todd,

I don't have that plugin in my listing, which I thought was kind of odd but
I guess that check_ssmtp = Secure SMTP.  Further research has found that the
check_ssmtp plugin is the check_tcp plugin yet forces the -S (SSL) check.
Which explains a lot.  I guess I could just use check_tcp unless someone can
tell me where to get check_smtp from, since I thought I downloaded the
latest version of the nagios plugins.

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?
