NAME

Net::OpenSSH::Compat::SSH2 - Net::OpenSSH adapter for Net::SSH2 API compatibility

SYNOPSIS

use Net::OpenSSH::Compat::SSH2 qw(:supplant);

use Net::SSH2;

my $ssh2 = Net::SSH2->new;
$ssh2->connect('host');
$ssh2->auth_publickey("jsmith",
                      "/home/jsmith/.ssh/id_dsa.pub",
                      "/home/jsmith/.ssh/id_dsa");
my $c = $ssh2->channel;
$c->exec("ls");
print while <$c>;

$c->close;
print "exit status: ", $c->exit_status, "\n";

DESCRIPTION

This module implements Net::SSH2 API on top of Net::OpenSSH.

After the module is loaded as...

use Net::OpenSSH::Compat::SSH2 qw(:supplant);

it will supplant the Net::SSH2 module as if it was installed on the machine and use Net::OpenSSH under the hood to handle SSH operations.

Most programs using Net::SSH2 should continue to work without any change.

Setting defaults

The hash %Net::OpenSSH::Compat::SSH2::DEFAULTS can be used to set default values for Net::OpenSSH and other modules called under the hood and otherwise not accessible through the Net::SSH2 API.

The entries currently supported are:

connection => [ %opts ]

Extra options passed to Net::OpenSSH::new constructor.

Example:

$Net::OpenSSH::Compat::SSH2::DEFAULTS{connection} =
  [ ssh_path => "/opt/SSH/bin/ssh" ];

channel => [ %opts ]

Extra options passed to Net::OpenSSH::open_ex method.

sftp => [ %opts ]

Extra options passed to Net::SFTP::Foreign::new constructor.

$Net::OpenSSH::Compat::SSH2::DEFAULTS{connection} =
  [ read_ahead => 128 * 1024, queue_size => 20 ];

BUGS AND SUPPORT

This is a work in progress.

Besides that, there are some functionality of Net::SSH2 that can not be emulated with Net::OpenSSH. Fortunately, the missing bits are rarely used so probably you may not need them at all.

Specifically, the return values from the $ssh2->method($ATTR) are not real but faked ones. auth_list return value is also faked.

Anyway, if your Net::SSH2 script fails, fill a bug report at the CPAN RT bugtracker (https://rt.cpan.org/Ticket/Create.html?Queue=Net-OpenSSH-Compat) or just send me an e-mail with the details.

Include at least:

1 - The full source of the script

2 - A description of what happens in your machine

3 - What you thing it should be happening

4 - What happens when you use the real Net::SSH2

5 - The version and name of your operating system

6 - The version of the OpenSSH ssh client installed on your machine (ssh -V)

7 - The Perl version (perl -V)

8 - The versions of the Perl packages Net::OpenSSH, IO::Pty and this Net::OpenSSH::Compat.
