+
+Q: How do you supply a password to connect with ssh within a perl script
+using the Net::SSH module?
+
+A: You don't.  Use RSA or DSA keys.  See the ssh-keygen(1) manpage.
+
+Q: My script is "leaking" ssh processes.
+
+A: See L<perlfaq8/"How do I avoid zombies on a Unix system">, L<IPC::Open2>,
+L<IPC::Open3> and L<perlfunc/waitpid>.
