Poor's man configuration management.

This software is a wrapper around ssh.

Things it does:

• Connects to machines.
• Resolves hostnames (right domain or hostname).
• Does authentication (right user, password or ssh key).
• Inserts commands into your bash history / bash profile.
• Future connections use the same SSH master process.
• (optionally) Execute a script on the host.
• (optionally) Loops over each matching host.

Requirements

Perl modules you'll need:

• Net::OpenSSH
• Expect (if using su)
• List::MoreUtils
• Net::Server::Multiplex
• IO::Stty

Sample config

GLOBAL,prefix,.domain.lan,0,myuser,environment

web01

This roughly translates to:

ssh [email protected]

You need to set up an ssh key or password to log in as "myuser".

If "myuser" is not root, the script uses the configured command ("su_command" by default) and the configured class (Supass by default) to get root.

The sample backend just returns a string but you can write a more complex one.

Multiple hosts

If you want to connect to several hosts consecutively you can use:

./s '/^serv/' host123

And the script will loop over serv1, serv2, ..., and host123.

Scripts

You can also write a script, place it under "scripts/" ("scripts_dir"), and run it on several hosts.

This command just list the hosts:

./s -n -s script1 '/^host\d+/'

When sure you can do:

./s -s script1 '/^host\d+/'
