Fair enough. Next time I'll read your mind. This time, I'll just point out that you didn't mention wvdial in your posting. > With pon/poff it's all ok. i don't have to > be in group dialout nor have g+w permission on /dev/ttyS1.

Why should your being entitled to run wvdial for PPP mean that you should have write-access to all the serial ports? > If it has g+w, wvdial is working ok.

Killing pppd with SIGTERM seems to restore the port permission, whereas there are/have been bugs in pppd where exiting in some other manner (e.g. PAP failure) has not restored them. If wvdial used -SIGKILL for example, it would be difficult for pppd to do anything about it. A workaround may be a sudo'd script that checks whether pppd is running and restores the permission if it isn't. I'd be very unhappy if pppd didn't g-w the serial port it uses. Oh, and BTW, Debian has to be built for people who *do* care, so advice that compromises security is not to be welcomed here and must certainly be flagged in case it catches out other people who would then be exposed. > PS. Don't CC me. I got everything twice. Then why have you set Mail-Followup-To: to yourself as well as Debian?
