NAME

Net::SSH::Mechanize::Session - manage a running ssh process.

SYNOPSIS

This class represents a sunning ssh process. It is a subclass of AnyEvent::Subprocess::Running, with methods to manage the authentication and other interaction with the sub-process.

Typically you will not create one directly, but obtain one via Net::SSH::Mechanize::Session->login, or Net::SSH::Mechanize->session

You might invoke methods directly, or via Net::SSH::Mechanize instance's methods which delegate to the instance's session attribute (which is an instance of this class).

   use Net::SSH::Mechanize;

   my $mech = Net::SSH::Mechanize->new(hostname => 'somewhere');

   my $session = $mech->session;
   # ...

CLASS METHODS

$obj = $class->new(%params)

Creates a new instance. Not intended for public use. Use Net::SSH::Mechanize->session instead.

INSTANCE ATTRIBUTES

$params = $obj->connection_params

This is a read-only accessor for the connection_params instance passed to the constructor by Net::SSH::Mechanize.

$obj->login_timeout($integer) =head2 $integer = $obj->login_timeout

This is a read-write accessor to the log-in timeout parameter passed to the constructor.

If you plan to modify it, do so before ->login or ->login_async has been invoked or it will not have any effect on anything.

INSTANCE METHODS

Note, all of these will throw an exception if used before ->login or before ->login_async has successfully completed, except of course ->login and ->login_async themselves. These latter methods do nothing after the first invocation.

$session = $obj->login

This method logs into the remote host using the defined connection parameters, and returns a Net::SSH::Mechanize::Session instance on success, or throws an exception on failure.

It is safe to use in AnyEvent applications or Coro co-routines, because the implementation is asynchronous and will not block the whole process.

$condvar = $obj->login_async

This is an asynchronous method used to implement the synchronous ->login method. It returns an AnyEvent::CondVar instance immediately, which can be used to wait for completion, or register a callback to be notified when the log-in has completed.

$obj->logout

Logs out of the remote host by issuing an "exit" command.

$condvar = $obj->capture_async($command)

The returns a condvar immediately, which can be used to wait for successful completion (or otherwise) of the command(s) defined by $command.

$result = $obj->capture($command)

This invokes the command(s) defined by $command on the remote host, and returns the result.

$condvar = $obj->sudo_capture_async($command)

The returns a condvar immediately, which can be used to wait for successful completion (or otherwise) in a sudo'ed sub-shell of the command(s) defined by $command.

A password is required in connection_params for this to authenticate with sudo.

$result = $obj->sudo_capture($command)

This invokes the command(s) defined by $command in a sudo'ed sub-shell on the remote host, and returns the result.
