It has nothing to do with -accel-pptp plugin [1]. - -This plugin adds support for upstream kernel PPTP implementation in pppd daemon. -Only PNS (client) part of PPTP is implemented, as we don't use Android devices -in PAC mode. - -In general case, the execution flow for VPN startup on Android devices is: - 1. Run PPTP client (mtpd) - 2. mtpd obtains remote Call ID on OCRP (Outgoing-Call-Reply) packet - 3. mtpd creates PPTP socket - 4. mtpd runs pppd, passing PPTP socket as to pppopptp-android (as parameter) - 5. pppd dlopen() pppopptp-android plugin (because it received corresponding - arguments from mtpd) - -Main task of this plugin is to obtain PPTP socket FD from mtpd and pass it -back to pppd when .connect() callback is executed. - -All control packets are handled in mtpd. PPP packets (like LCP) are handled in -pppd. Data packets are handled by kernel PPTP driver. - -[1] http://accel-pptp.sourceforge.net/ |
