+Q: I get a message saying something like "ioctl(TIOCSETD): Operation
+not permitted". How do I fix this?
+
+A: This is because pppd is not running as root. If you have not
+installed pppd setuid-root, you will have to be root to run it. If
+you have installed pppd setuid-root and you still get this message, it
+is probably because your shell is using some other copy of pppd than
+the installed one - for example, if you are in the pppd directory
+where you've just built pppd and your $PATH has . before /usr/sbin (or
+wherever pppd gets installed).
