+
+Q: How do you supply a password to connect with ssh within a perl script
+using the Net::SSH module?
+
+A: You don't (at least not with this module). Use RSA or DSA keys. See the
+ quick help in the next section and the ssh-keygen(1) manpage.
+
+A #2: See L<Net::SCP::Expect> instead.
+
+Q: My script is "leaking" scp processes.
+
+A: See L<perlfaq8/"How do I avoid zombies on a Unix system">, L<IPC::Open2>,
+L<IPC::Open3> and L<perlfunc/waitpid>.

+
+=item 1 Generate keys
+
+Type:
+
+ ssh-keygen -t rsa
+
+And do not enter a passphrase unless you wanted to be prompted for
+one during file copying.
+
+Here is what you will see:
+
+ $ ssh-keygen -t rsa
+ Generating public/private rsa key pair.
+ Enter file in which to save the key (/home/User/.ssh/id_rsa):
+ Enter passphrase (empty for no passphrase):
+
+ Enter same passphrase again:
+
+ Your identification has been saved in /home/User/.ssh/id_rsa.
+ Your public key has been saved in /home/User/.ssh/id_rsa.pub.
+ The key fingerprint is:
+ 5a:cd:2b:0a:cd:d9:15:85:26:79:40:0c:55:2a:f4:23 User@JEFF-CPU

+=item 2 Copy public to machines you want to upload to
+
+C<id_rsa.pub> is your public key. Copy it to C<~/.ssh> on target machine.
+
+Put a copy of the public key file on each machine you want to log into.
+Name the copy C<authorized_keys> (some implementations name this file
+C<authorized_keys2>)
+
+Then type:
+
+ chmod 600 authorized_keys
+
+Then make sure your home dir on the remote machine is not group or
+world writeable.
