Ahh... you're the guy who copied the whole system without preserving
the permissions. "pppd" is supposed to be suid root. Does it run OK if
you're logged in as root? If so, you can fix it by running, as root
"chmod +s /usr/sbin/pppd".

It depends. If you're running both as root, it shouldn't matter. It could
be that a process exited abnormally at some time, leaving an advisory lock
on /dev/tty00. (pppd checks -- cu is too stupid to care.) In that case,
you can delete the device file and remake it, or just reboot.
