Use pfsense notification/SMTP function in sgerror.php (squidguard) - help

Nachtfalke

Hi,

I am not good in php and web technologgies so I asked a colleague to modify parts of the sgerror.php of squidguard to give the user the ability to send me an e-mail with the blocked URL and a comment so that I am able to unblock the URL.

My colleague used sendmail for php but it does not work and we found out that sendmail seems not to be installed/running on pfsense.

Now my idea is to use the SMTP credentials uses unter SYSTEM –> ADVANCED --> NOTIFICATIONS in this sgerror.php file to authenticate on the destination E-Mail server.
Easiest would be probably to "steal" the function from a pfsense file which for example triggers "gateway down" event. Then "just" put this function into the sgerror.php and that's it.

So where to find the function which triggers an E-Mail event for "Gateway down" or something else?
Or did anyone else built a sgerror.php which can already do what I want?

Thank you very much for your feedback!

Hi,

I tried to install sendmail on my pfsense 2.0.3 with freebsd 8.1 from this location:


pkg_add -r http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/amd64/8.1-RELEASE/packages/All/sendmail-8.14.4_2.tbz

It is now ih the list when doing


pkg_info

but I cannot find the confi file like


sendmail.cf

Isn't that the correct way to install an additional package which is not available in the package manager of pfsense?

We don't include a config file for sendmail, you'd have to make one.

But sendmail is way overkill.

Look at what I did for the arpwatch package a couple weeks back. A small php script that gets dropped in where sendmail would go, and lets programs get mail out.

You probably mean this one:
https://github.com/pfsense/pfsense-packages/blob/master/config/sm.php

Unfortunately I am still using pfsense 2.0.3 and not 2.1.

Then get with the times already and upgrade :-)

It's not an unreasonable restriction these days. The function that script calls only exists on 2.1.

Sure it could be done on 2.0.x but it means copying a bunch of code and a lot of extra work.
