ssht

SSH client wrapper for easily connecting to hosts

This wrapper for the well known ssh client makes it possible to connect to the right server with just typing a part of the host name. The external sources are queried using the search term and those matching the string will be presented as an option.

Current supported sources:

• JSON file
• MySQL database
• JSON API endpoint
• Custom parser class

Installation

Install ssht using pip:

pip3 install ssht

or if you want the latest version:

pip3 install https://github.com/hkraal/ssht/archive/master.zip

Usage

ssht [-h] name [-4] [-6]

positional arguments:
  name        name of the host to connect to

optional arguments:
  -h, --help  show this help message and exit
  -4          connect using ipv4 (skip dns if ipv4 address is defined)
  -6          connect using ipv6 (skip dns of ipv6 address is defined)

Example of a connection

$ ssht host01
1) root@host01.exmaple.com
2) host01.exmaple.com
Connect to: 1
Connecting to "host01.example.com"
root@host01:~$

Configuration

Create ssht folder in home directory

mkdir ~/.ssht

Configure sources in ~/.ssht:

Define servers in JSON format:

{
	"hosts": [
	  {
		"port": "2222",
		"hostname": "host01.example.com",
		"ipv4": "192.168.0.2",
		"user": "root"
	  },
	  {
		"port": "2222",
		"hostname": "host01.example.com",
		"ipv4": "192.168.0.2",
	  }
	]
}

Define servers in MySQL:

{
  "config": {
    "host": "localhost",
    "user": "username",
    "password": "passeword",
    "database": "infra"
  },
  "query": "SELECT hostname, port, ipv4, ipv6, user FROM servers"
}

Define JSON API endpoint:

{
	"config": {
		"url": "http://ssht-api.dev",
		"headers": {
			"Authentication": "bla:huk"
		}
	}
}

Define custom class:

1. Create a Python package containing your class

from ssht.plugins import Parser, Host


class ExampleParser(Parser):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self._files = self.get_files('.custom')

    def search(self, needle):
        return [
            Host(hostname='host01.example.com', ipv4='192.168.0.2'),
        ]

2. Enable your class in ~/.ssht/config.json

{
    "parsers":
    [
        "ssht.plugins.JsonParser",
        "ssht_provider.ExampleParser"
    ]
}
