How to detect auto dialers

[chamalsl]

Hi,

What are the possible ways to detect auto dialers ,which make calls without users consent, in linux.

Is it possible to disable dialing phone numbers completely in linux.

Thanks.

I don't know how you came to ask this question but the auto dialer problem was something of the past millennium and for a completely different OS. If you think "dialer" as in "old school dial-up connection" then modem hardware, pppd and chat binaries all need to exist (OK, the latter can be introduced) and pppd is by default not installed setuid root IIRC. As far as detection goes
- a (deleted?) process will be connected to the TTY the modem is on,
- that process might have a (deleted?) caller script somewhere,
- the modem could be interrogated for the connection details,
- dmesg might show clues
and I probably forgot a few things.
