Why this project?

Using an OSx (or Linux) environment, when you need to manage lot of servers it could be difficult to remember all the hostnames or ip addresses.
On the Windows system I used to use mRemote, but I didn't find anything similar on OSx/Linux.
That's the idea to create a simple CLI program allowing to store all the connection information using tags (like mRemote does).

How to install the project

It's a NodeJS project and actually it is not available on the npm repository. So, the better way is downloading sources from github and install globally from sources:

git clone https://github.com/mmornati/ssh2-keeper.git
cd ssk-keeper
npm install -g .

Installation Image

The ssh2-keeper is now available as sk command on your system.


After the global installation the configuration folder is into the global node modules installation folder.
You can check which one is on your system using:

npm root -g

Node Modules Folder

On my system for example, the global folder is /usr/local/lib/node_modules which means, after the ssh2-keeper installation, the configuration folder will be /usr/local/lib/node_modules/ssh2-keeper/config.
Inside this latest one you will find a default.json file and you must configure the database folder.

  "db_path": "/Users/mmornati/ssh2-keeper",
  "server_collection": "servers",
  "tag_collection": "tags",
  "default_username": "mmornati",
  "show_ssh_command": true


If you globally installed the module, using sk --help allow you to retrieve the script documentation.

sk --help
Successfully connected to : ./db
USAGE: node sk [OPTION1] [OPTION2]... arg1 arg2...
The following options are supported:
  -v, --verbose       	Show verbose log
  -t, --tag           	Tag(s) to allow you to find server (multiple)
  -h, --hostname      	Hostname of your server
  -a, --admin_server  	If you need to connect to an Admin server to reach your target. Ex: ssh -tt pi@ ssh -tt pi2@
  -i, --ip            	Server IP address.
  -u, --username      	Username to connect to your server. If empty the one in configuration file be used
  -o, --operation     	One of ADD, SEARCH or DELETE

Add a new server

sk -o add -h server35.mornati.net -i -t jenkins -t slave -t slave04 -t integration

This will add a server (if the hostname it is not already present with the same hostname) with the provided parameters and tags.


With a line like the previous one we've seen, you can also update server parameters:

sk -o add -h server35.mornati.net -i

In this way, for example, if the server was already present into database, you will update the IP address. All others information already present into database will be kept.
In the same way you can add a new tag to the server

sk -o add -h server35.mornati.net -t mypersonalserver

will add a new tag to the server (if not already present).

Update Tags

The most used function will surely be the search one. You can search a server using the hostname, which will provide you the list of data known about the server:

sk -o search -h server20.mornati.net
Successfully connected to : ./db
{ hostname: 'server20.mornati.net',
  ip: '',
  tags: [ 'www', 'front', 'front02', 'preprod', 'france' ],
  _id: '15404e5a1b134cb289ffae0cc89968ca' }
Added to clipboard

Search by Hostname

Or you can search using tags: it will return you the intersection between all provided tags.

sk -o search -t prod -t front -t italy
Successfully connected to : ./db
ssh mmornati@server1.mornati.net
ssh mmornati@server2.mornati.net

It will return you all the 'front' and 'prod' servers for 'italy' (servers must have the 3 tags to be into the list).
When the list gives you a single result, the ssh command will be directly in your clipboard: with a simple CTRL+V you can use it! :)

Search improved

As I said before, this one is the most used function, I created an 'undocumented' function allowing you to search in this way:

sk search prod front01 italy
Successfully connected to : ./db
ssh mmornati@server1.mornati.net
Added to clipboard

So, without providing the option name. In this case:

  • the first argument is the operation (SEARCH, ADD)
  • if it is SEARCH from the second arguments all others will be consider as tags
  • if it is ADD the second argument is the hostname and all others are tags

Search Prod Italy

Search by Steps


To initialize my work environment database I used 'spreadsheet' (yes, it is amazing, but it was quick!).


I just copied hostnames and IPs I had on another document, and then, using the spreadsheet's CONCATENATE function I was able to generate the list of 'ADD' commands.

Server with proxy

If you are using an admin server between you PC and the target server (for example on the configuration environment) you can store this information into the database (admin_server) and the ssh command sent by the ssh2-keeper will be ready to use.

sk search preprod france front02
Successfully connected to : ./db
ssh -tt mmornati@adm01.mornati.net ssh -tt mmornati@server20.mornati.net
Added to clipboard

Next Steps

  • Better management of Users (per server and tag)
  • Add support to ssh_key per server and tags
  • What you need to improve it :)
