Nagios Support Forum

I am getting the following error:

EMAIL DELIVERY CRITICAL - smtp failed: SMTP SEND CRITICAL - Invalid response for STARTTLS: 500 5.5.1 Unknown or unimplemented command at /usr/local/nagios/libexec/check_smtp_send line 110

i looked at line 110, was not sure what to delete.

Ideas?

Could you please post for us what you have on line 110?

110 $smtp = Net::SMTP::TLS->new($smtp_server, Timeout=>$timeout, Port=>$smtp_port, User=>$username, Password=>$password);
111 }

Still cannot get this to work.

You might be missing some perl libraries.

A yum search pulled up these packages for perl SMTP:


perl-Net-SMPP.noarch : Pure Perl implementation of SMPP 3.4 over TCP
perl-Net-SMTP-Multipart.noarch : SMTP Multipart messages
perl-Net-SMTP-SSL.noarch : SSL support for Net::SMTP
perl-Net-SMTP-TLS.noarch : SMTP client supporting TLS and AUTH
perl-Net-SMTP_auth.noarch : SMTP_AUTH wrapper for Net::SMTP
perl-Net-SNMP.noarch : Net-SNMP Perl module

Not sure which one you might need.

I get the following:

perl-Net-SNMP.noarch 5.2.0-4.el6 @epel
perl-Net-SSLeay.i686 1.35-9.el6 @base

Just for fun lets try installing one supporting TLS, since the error seems to point to a problem with that:
Does that plugin have any hints in the help output as to what perl modules it needs?

Setting up Install Process
Package perl-Net-SMTP-TLS-0.12-1.el6.rf.noarch already installed and latest version
Nothing to do

Are you sure your smtp server uses TLS?

It does not, i put a che k in the. O. That sYs not to use tsl or ssl
