Update ppp with ubuntu patch - traxtopel - 11th Nov, 2013 08:47 PM
How do I request that the current ppp package gets updated with an additional ubuntu patch.
Current ppp package when used in conjunction with a pptp vpn connection fails.
When compiled with the following patch, it works perfectly.

@traxtopel
until this patch gets into upstream (if ever), providing custom ppp package would mean taking care of each upstream (debian/raspbian) update and recompiling (maybe even updating the patch itself).
wouldn't be better to just document this here / github for XBian with an proposed solution to put "ppp_generic" into /etc/modules for those using pptp vpn setup?
thanks for posting this anyhow.
