Email notification if have connection OpenVPN

karanik

Hello,
~~Is it possible the pfSense OpenVPN server sent me email on every connection?~~ Is pfSense able to send mail on every OpenVPN successful connection ?

There is not currently a hook for e-mail notification there. It could be added without too much effort, at least a manual hacky way. A proper setup with a GUI option and so on would be a bit more complex.

Have a look at the OpenVPN auth script in /var/etc/

Can i have example?

[2.2.4-RELEASE][admin@pfsense]/root: ls /var/etc/
apinger.conf                inetd.conf                  openvpn                     resolv.conf
cert.pem                    l2tp-vpn                    openvpn-csc                 resolvconf.conf
filterdns.conf              lighty-webConfigurator.conf radvd.conf                  squid.passwd
hosts                       ntpd.conf                   relayd.conf                 syslog.conf

I forgot things got shifted around, it's now at /etc/inc/openvpn.auth-user.php

Hi,
I don't know if you already find it, but it was my same request.
To do that I just modify the connect and disconnect script on openvpn on pfsense 2.2.4

/usr/local/sbin/openvpn.attributes.sh

and add the line on connect and disconnect:

/bin/echo "Connexion de ${common_name} date" | /usr/local/bin/php /usr/local/bin/mail.php -s"Connexion de ${common_name} date"

Best regards,

Just to let you all know that if sending email fail ( because can't deliver email - mail server offline… ) the vpn connection will fail ( after established ) and clients will not be able to connect ever... I had to debug this problem today...

if [ "$script_type" = "client-connect" ]; then
        if [ -f /tmp/$common_name ]; then
                /bin/cat /tmp/$common_name > $1
                /bin/rm /tmp/$common_name
