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.

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. -Mark <div class=MsoNormal align=center style='margin-left:.5in;text-align:center'> <hr size=2 width="100%" align=center> </div> From: Todd Barbera [mailto:todd_barbera@wgbh.org] Sent: Thursday, December 08, 2005 3:10 PM To: 'Mark Pearson'; nagios-users@lists.sourceforge.net Subject: RE: [Nagios-users] check_ssmtp (check_tcp) SSL Errors </div> 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.

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.
