[pptp-devel] PPTP terminate-from support

[Hrvoje C. <hrv...@gm...>]

Hi everyone,

I'd like to try and submit a patch for a feature I needed and had to
implement myself, so my reasoning was to try and help someone else and
the project as well.

TL;DR - I wasn't able to connect to some Cisco gear, the admin kept
mentioning he set terminate-from to something he provided and I need
to set my hostname. I had no idea what he was on about, but decided to
investigate.

Cisco gear apparently can assign users to different VPDN groups using
terminate-from option. This references to the hostname field in the
PPTP control header that is hardcoded to "local" in Linux PPTP client.
This option merely provides user the means to specify the client
hostname that's going to be reported to the server. If nothing is
provided, it defaults to local and there is no change in behavior.
Other PPTP stacks can do this apparently (MikroTik routers for
example) so I thought it would be cool if Linux could as well :)

I would like to thank everyone for the hard work in maintaining this
alive. Apparently legacy systems are pretty much all around us and
having software that works is a great thing.

Cheers!

Hrvoje
