[Nagiosplug-devel] Recent patch to check_smtp.c

[Benjamin Madsen]

Running the recent patch against a Microsoft 2000 Server w/ Exchange SMTP 
agent caused problems with the SMTP_DUMMYCMD check.  Apparently, Exchange's 
SMTP agent looks for a '\r\n' as opposed to just a '\n'.  Since I am 
unfamiliar with how to patch things, could somebody do that?

Also, I'm wondering what implications changing the SMTP_DUMMCMD to 
"MAIL\r\n" would be... Any ideas?

Thanks,

Hi plugin developers,

sendmail will create a syslog entry when a session only issues a quit
command, looking roughly like this:
Jun  9 19:50:44 beaulieu.ixos.de sendmail[26790]: NOQUEUE: mucnm01.ixos.de
[149.
235.38.10] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

This clobbers the syslog of every machine where SMTP is checked and can be
prevented by issuing a command. Thze following patch does just that.
It is a diff against the netsaint-plugins-1.2.9-4 plugins/check_smtp.c file
(which I checked in locally as 1.1).
Apologies if this change was already made in the latest release of the
plugins, I haven't checked.

Have fun,
