Hi!

This is my second try to get comments for my WTMP support for OpenVPN 2.1.

Description:

  If compiled in and activated in the configuration, OpenVPN will put a
  wtmp entry into the logfile for each connection include the username,
  it's VPN ip, the real IP the client connected from and the times the
  session was opened and closed.

  It is possible to let multiple instances of OpenVPN on the same host
  use the same wtmp file.

  You will be able to distinguish between vpn servers in a commonly use
  file by specifying different "server ids" (two digit integer value),
  which will be used in the wtmp line string.
 
  This provides an OpenVPN admin with a simple database of all connections
  to his VPN servers and the ability to easily track down when, who was
  logged in and from where.


One thing which is not perfect is that, the uid/gid for the wtmp file
are looked up manually in wtmp_init() as context->c0 struct is not yet
available.
Maybe wtmp_init() could be called a bit later at a usefull place to
avoid this doulbe lookup.

I would very much like to get the WTMP logging support included in
OpenVPN 2.1 as it will help people to get an overview about the usage
of their VPNs and prepares abuse-people with relevant information if
problems occur.

Some time ago, this feature was requested, btw.

Ciao
Max
