In the pptpconfig GUI we must define a handler for SIGINT before starting pppd, because if we don't the SIGINT we send to pppd comes back to us because of "kill(0,sig)". Why is this? popen is used to activate pppd, so that output from pppd is redirected to GUI. -- James Cameron http://quozl.netrek.org/ HP Open Source, Volunteer http://opensource.hp.com/ PPTP Client Project, Release Engineer http://pptpclient.sourceforge.net/ -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
