Simple program to connect to servers from a list.

This is a simple program to load servers from a file, list them, then allow you to login, SSH mount, etc.

Features provided by a terse command line syntax:

• Login using a terminal instance on the command line via SSH.
• Invoke an xterm on a configured host.
• Mount and unmount a SSH Fuse directory.
• Invoke a Emacs session via SSH.
• Print environment in a bash export format for scripting.
• Output a bourne shell script that does what the script would do for a particular environment (per -n option).

Other commands are easily configurable in cli.py.

Obtaining

The easist way to install the command line program is via the pip installer:

pip install zensols.hostcon

Binaries are also available on pypi.

Usage

First, create a configuration file. Examples used by the test cases are given here. Below is a simple example that declares an SSH host jove on the (default) port 22 with SSH Fuse mount options convenient for a MacOS client.

[default]
host_name=jove
ssh_port=22
ssh_switches=-X -Y
mount_options=reconnect,sshfs_sync,no_readahead,sync_read,cache=no,noreadahead,noubc,noappledouble,noapplexattr

Save this example to ~/.hostconrc or anywhere else specified in environment variable HOSTCONRC. Now we can get include this as environment:

$ hostcon env
export DOMAIN=None
export HOST_NAME=jove
export SSH_PORT=22
export USER_NAME=someuser

Start an XTerm on the host:

$ hostcon
invoking ssh -X -Y -f -p 22 someuser@jove /usr/bin/xterm

See the test cases for more examples of how to configure and alias host information.

Help

The usage is given with -h:

$ hostcon -h
Usage: hostcon <list|...> [options]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -s, --short           short output for list
  -w NUMBER, --whine=NUMBER
                        add verbosity to logging
  -n HOST_NAME, --hostname=HOST_NAME
                        the host to connect to
  -d, --dryrun          dry run to not actually connect, but act like it
