Openvpn pam authetication - two process created

[sunilmh]

Hi,

I am running openvpn server by enabling pam authetication for the login functaionlity.
Following statement added in my server.conf file

plugin /usr/local/src/openvpn-2.1.4/plugin/auth-pam/openvpn-auth-pam.so login

When i check my process list it shows two openvpn processes, as shown below,

root 14461 0.0 0.0 5400 432 pts/1 S 11:07 0:00 /usr/local/sbin/openvpn --daemon --writepid /var/run/openvpn/server.pid --config /usr/local/src/openvpn-2.1.4/sample-config-files/server.conf --cd /usr/local/src/openvpn-2.1.4/sample-config-files
root 14467 0.0 0.2 5784 1292 ? Ss 11:07 0:00 /usr/local/sbin/openvpn --daemon --writepid /var/run/openvpn/server.pid --config /usr/local/src/openvpn-2.1.4/sample-config-files/server.conf --cd /usr/local/src/openvpn-2.1.4/sample-config-files

Can anyone help me out in understanding why it creates two processes when I enable pam authetication plugin.

Thanks,
Sunil

openvpn plugins are run in a separate process (by design). This is one of the main reasons why plugins are often faster compared to a scripting (non plugin) setup.
