- Fix mkdir error message and extraneous warning, patch from Ofer Nave
<onave@bizrate.com>, thanks!
+ - Remove quit from the SYNOPSIS, and add a no-op quit method anyway,
+ for the sake of being an easier Net::FTP replacement. Thanks to
+ Zak Zebrowski <zakzebrowski@yahoo.com>, tvilliers at Lastminute.com,
+ Joe Smith <joe@inwap.com> and others for the pointer.
+ Closes: CPAN #14803
+ - Fix unused "interactive" option in new method. Huh. Thanks to
+ John L. Utz III <utz@singingfish.com>.
+ - Document need to log into boxes once first.
+ - Add links to the more current stuff on CPAN.
+ - Patch to prevent an active CHLD reaper from picking up our ssh
+ process from from peterspeltz@yahoo.com. Closes: CPAN#19189
+ - Documentation patch about ssh-keygen from terrence brannon
+ <tbone@directsynergy.com>

=head1 FREQUENTLY ASKED QUESTIONS
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.
+A: You don't (at least not with this module). Use RSA or DSA keys. See the

+
+A #2: See L<Net::SCP::Expect> instead.
-Q: My script is "leaking" ssh processes.

+=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.

=head1 AUTHORS
+Could really use a maintainer with enough time to at least review and apply
+patches. Or the module should just be deprecated in favor of Net::SFTP::Expect
+or Net::SFTP::Foreign and made into a simple compatiblity wrapper.

-It's probably better just to use SSH1 or OpenSSH <http://www.openssh.com/>
+It's probably better just to use OpenSSH <http://www.openssh.com/> which is
+the de-facto standard these days anyway.
The Net::FTP-style OO stuff is kinda lame. And incomplete.
+iscp doesnt expect you to be logging into the box that you are copying to
+for the first time. so it's completely clueless about how to handle the
+whole 'add this file to known hosts' message so it just hangs after the
+user hits y. (Thanks to John L. Utz III). To avoid this, SSH to the box
+once first.
