Right - so the initial step would be to "disable" it to see what
process complains. If it's "pppd" that's causing problems, then that's
what you'll see in the logs; if it's "rxvt", then that's what'll be
reported.

No - that would be "chmod -w <filename>".

Then I can only wish you the best of luck in troubleshooting your
problems. I've never been good at running with both my feet tied in a
