Re: PPTP VPN plugin resurrected from the dead (Ubuntu Packages)

[Luís Miguel dos Reis Oliveira e Silva <luis silva axiomasoft pt>]

Hi Alexander,

I'm one of the users of your packages and first of all let me thank you for the good work!

yet, I noticed some problems with pptp plugin. Some of the options are not re-read correctly from the configuration. Let me explain: for example, when selecting one specific option for MPPE (either 128 or 40 bit), if I open the configuration again, the MPPE selection box is empty... This is just one example, but all problems I detected seem to be related to MPPE...

One potential problem is that when you get one vpn system connection with the same name of a physical ethernet system connection, they overwrite each other...

Also, I didn't manage to get a connection working...

Here goes the log excerpt from one attempt...
