=head1 NAME

App::assh - A wrapper around autossh.

=head1 VERSION

version 1.1.2

=head1 SYNOPSIS

A wrapper around autossh.

=for Pod::Coverage ports_config_file  ssh_config_file

=head1 MOTIVATION

`autossh` is a nifty little ssh-keepalive-connection-holder.

Passing in the ports for the keepalive can be clumsy though: `assh` helps you to avoid that.

=head1 USAGE

     assh
     assh HOSTNAME

=head1 REQUIREMENTS

First, you will need a file `~E<sol>.sshE<sol>config`. It looks something like this:

     Host foo
     HostName bar.example.com
     User baz

With this, you can already leverage standard `ssh` connections:

     ssh foo

... instead of

     ssh baz@bar.example.com

Next, generate a file `~E<sol>.autossh_rc` with the following format:

     foo 12345

... with the first entry on the line representing your `Host` in `~E<sol>.sshE<sol>config` and the second item on the line being the port over which to keep the autossh connection alive.

Now you can permanently connect using:

     assh foo

... with the connection kept alive across network switches and computer shutdowns.
