This is Net::SSH::Perl. It contains implementations of
both the SSH1 and SSH2 protocols.

PREREQUISITES

Protocol 1

    * Math::GMP (1.04 or greater)
    * String::CRC32 (1.2 or greater)
    * Digest::MD5
    * IO::Socket

Protocol 2

    * Crypt::DSA (0.03 or greater)
    * Crypt::DH (0.01 or greater)
    * Math::Pari (2.001804 or greater)
    * MIME::Base64
    * Digest::MD5
    * Digest::SHA1
    * Digest::HMAC_MD5
    * Digest::HMAC_SHA1
    * Convert::PEM (0.05 or greater)
    * IO::Socket

It also optionally requires Digest::BubbleBabble for
generating bubble babble fingerprints, and Crypt::RSA
(1.37 or greater) if you want to use RSA key files in SSH2.

Note that RSA key files in SSH1 do not require Crypt::RSA.

INSTALLATION

Net::SSH::Perl installation is relatively straightforward. If
your CPAN shell is set up, you should just be able to do

    % perl -MCPAN -e 'install Net::SSH::Perl'

If you don't like that, you can download the distribution; the
latest version on CPAN can be found at

	http://search.cpan.org/dist/Net-SSH-Perl/

Download it, unpack it, then build it as per the usual:

    % perl Makefile.PL
    % make && make test

Then install it:

    % make install

If you have problems, read on.

The only slightly complicated bit in the installation is
that you'll need to install Crypt:: modules depending on
which ciphers you wish to use. Much work has gone into
making this simple; you should be asked a question about
which ciphers you'll use, and the modules should be
downloaded and installed automatically.

If it doesn't work, or if you don't like this option, you'll
need to do the installations manually. In which case you'll
need to install the prerequisites listed above for your
chosen protocol, plus any additional Crypt:: modules you
wish to use.

SAMPLES/TUTORIALS

Take a look at the scripts in eg/ for help and examples of
using Net::SSH::Perl.

* eg/cmd.pl is just a simple example of some of the
functionality in the module;

# eg/pssh is an ssh-like client for running commands on
remote servers and connecting to a shell on remote servers;

* eg/pscp is a very simple scp-like script;

* eg/pssh-keygen is, as you might guess, an implementation of
ssh-keygen in Perl, using the Net::SSH::Perl key libraries.
It contains almost all of the functionality in the OpenSSH
version of ssh-keygen.

* eg/remoteinteract.pl is an example of using register_handler
to interact with a remote (interactive) command.

Both pssh and pscp support a subset of the command line options
that the actual tools support; obviously, only those options
supported by Net::SSH::Perl are supported by the two scripts.
