Re: [gentoo-user] wvdial: dialup for users

[Alan E. Davis]

Followup:

Oh, it work, ok...  until I rebooted.  Then it didn't work for ordinary
(non-super users) to #wvdial anymore.

Apparently, using udev and sysfs, etc., the devices are made on boot.
Funny, that I had to run MAKEDEV to make the higher numbered nodes, like
/dev/ttyS14, where my modem resides.  (The modem is not at this place on one
of the other systems I was playing around with---Knoppix, I think).

I am now going to learn udev.  I want to anyway: I like the way Ubuntu jumps
into action when a flash drive or a printer is plugged in, and so do my
GNU/Linux doubting friends :-).

So far, it looks like rules for creating the device nodes include
permissions components.

I will get there eventually.  Does anyone know, right off hand, though, how
to produce a rule to set up /dev/ttyS14 (/dev/tts/14 in the new
nomenclature) with permissions to allow dialup by anyone in group dialout?
It works to just do the following after booting:
      # chmod o+rw /dev/tts
      # chmod 0+rw /dev/tts/14

Is this a security issue?

Thanks for the advices so far.
