It works as follows. + +When a connection occurs, pptpd launches pppd with two additional +options. The first option directs pppd to load the pptpd-logwtmp.so +plugin. The second option is the IP address of the client. + + "plugin /usr/lib/pptpd/pptpd-logwtmp.so" + "pptpd-original-ip 10.0.0.1" + +The plugin defines the pptpd-original-ip option so that pppd will +accept it. + +If the plugin fails to load, pppd will fail in the usual manner. Such +a failure will usually be related to a missing file in /usr/lib/pptpd. + +The plugin asks pppd to notify it when IP comes up or goes down. + +When IP comes up, the plugin's ip_up() function executes, calling +logwtmp() to mark the user as logged in. Once this has happened, +commands like "who" will show the user. The tty will be set to the +PPP interface name. + +When IP goes down, the plugin's ip_down() function executes, removing +the entry from wtmp. Note that a "kill -9" on the pppd will result in +a user appearing to remain logged in. Don't use "kill -9", use an +ordinary kill. + +If pppd debug mode is enabled, the plugin announces it's version when +loaded, and reports the parameters it is handing over to the logwtmp +call. See the plugins/pptpd-logwtmp.c source. + +-- |
