Email Notification - OpenVPN Client Connect (Common Name)

mikekoke

Yes of course, I also took the test and received the notification.

You can connect to the VPN and disconnect as well, no errors with syntax or anything? It should work right away (latest OpenVPN version) so I can only suggest some other issue in your configuration.

I would try my original script and config (client-connect /root/notify.sh) and see if that works for you firstly. If it doesn't then there's more amiss than I could tell you.

mikekoke

I can connect to the VPN and everything works correctly, the script I am using is the first one, that of your post.

Armstrong

@mikekoke Can you run that notify script from the terminal verbose and see what happens?

It sounds like there's a problem with notifications, if everything's running but you're not getting an email. As I said it works straight away if you have email notifications on and everything on the latest version.

mikekoke

When I try to run it it exits written: Exception: Zend Extension ./disconnect.sh does not exist

edit: Problem solved. Thanks for your help.

Armstrong

@mikekoke What was the issue?

mikekoke

I had to create the files from the terminal.

i felt free to make some cahnges for a readable output.
the output from disconnect.sh received via e-mail looks now like this.

as far as i'm concerned with this output i don't need the connect.sh cuz as the more users there are
the more e-mails you'll receive.

the source for disconnect.sh is here.

#!/usr/local/bin/php -q
<?php
	require_once("/etc/inc/notices.inc");
	$local_connect_value = " \n user_name: " . getenv('common_name') . " \n vpn_client_ip: " . getenv('ifconfig_pool_remote_ip') ." connected from " . getenv('trusted_ip') . " on " . date('F j, Y, g:i a');
	if ( strrchr (__FILE__ , 'disconnect') ) {
	$local_connect_value .= ", \n duration : " . round(((getenv('time_duration'))/3600),2) . "  hours, or " . round(((getenv('time_duration'))/60),2) . "  minutes, or " . getenv('time_duration') . "  seconds,\n upload from vpn-client (received) : " . round(((getenv('bytes_received'))/1048576),2) . " MB, \n download to vpn-client (send) : " . round(((getenv('bytes_sent'))/1048576),2) ." MB. \n DISCONNECTED.";
	}
	notify_all_remote($local_connect_value);
?>

to reduce the mass on mails i was thinkin to use disconnect.sh with (client specific overrides)

but it was not workin and ended with someting like this:
Options error: option 'client-disconnect' cannot be used in this context

The main reason i wanted to do this, i put my clients in categries like

management (trusted)
sysops (trusted)
employees (trusted ;)
contractors (notification needed)

so that notification will only be sent if (untrusted or notification needed) as i mentioned earlier reduce tons of mails.
but i'll open a topic on this one and edit this post later on.

any hints are welcome

@noplan That definitely looks a lot better format-wise, thanks for the update. PHP isn't my strongest area.

I only have a small number of users so it's OK with me to have the number of emails I do, though for a larger organization it makes sense. I'm afraid I couldn't comment on the use of client overrides, but someone else may be able to provide advice.

noplan

i'm so happy that you came up with a version i can play on.
and look its workin. pretty fine.

mybe a nice project.
so a weekly report of VPN-clients "timesheets" could be generated

but maybe all things niceToHave on a firewall ;)

writtin this post
i am thinking to write the informations vom disconnect.sh into a txt file and send it via cron to
another machine doing the formating and generating a sweet pdf. (this could be fun i think )

Hi guys, sorry if I reopen this discussion;

I have configured the pfsense notifications and by sending the smtp test, the e-mail will arrive safely.
I created the notify.sh file and placed it under root
I ran the command: chmod + x /root/notify.sh to make it executable
I also ran the ls -al notify.sh command and the result is this:
but I don't receive any email when I connect remotely, nothing at all :(
The notify.sh file contains this:

I tried to manually start the notify.sh file with the ./notify.sh command under root, but nothing happens ...
at this point I would like to check the notification logs and together with you understand the problem. Do you know where the notification logs are located?

mikekoke

Create the notify.sh file from the pfsense gui with Diagnostics -> Edit File or from the terminal, I had the same error, I had created the file on windows and moved it to pfsense through winscp but it didn't work.

vettalex

@mikekoke Hello and thank you first.
After some time I managed to create the file and compile it, but despite this, it still doesn't go.
I did this procedure: notify.sh diagnostics.JPG
Compiled like this and saved:
notify.sh diagnostics intern.JPG
After that I sent the command chmod +x /root/notify.sh from ssh (putty), since I don't know how to send it from diagnostics-command prompt.
Where am I wrong?

Did you definitely add the client-connect /root/notify.sh part to the configuration of OpenVPN?

vettalex

@Armstrong Yes, in OpenVPN - Server - Edit Server:

@vettalex OK, I just tested by running my own notify.sh (which is different now to the one you're using) and that sends me an empty email. That suggests you have a problem with the notification and probably some kind of syntax error.

I would maybe try to run php -l notify.sh or lint the raw php to see if there are any syntax errors. I would generally suggest coding the script yourself from scratch (not copying and pasting) to avoid random errors. Lint first, then rebuild and test again. If the code checks out you have a notification issue.

Equally I would test with one of the newer notify.sh scripts deeper into the thread.

Hey folks
What I don't get and what's pretty frustrating
Readin this from top to bottom gives you a step by step howto for dummies to achieve a pretty professional solution for the request the only f#@&* thing u have to do is read and think

I don't get it
NP

vettalex

@Armstrong Just done, the result I think is, no syntax errors:
no error.JPG

@Armstrong Maybe there we are .... I am finding these errors .. even if they do not correspond to the sending time of the notify.sh scirpt (how can I check the correct date and time of pfsense?).
The strange thing is that the SMTP test during the configuration of the notification, is successful:

Everything ok, it was a google problem ... I don't know what problem it was. I used another email and everything works. Thanks a lot to all guys
