Organizing ssh keys of users

• create a file <username> inside directory called keys and add any number of keys there. A user can have multiple ssh keys.
• Eg: create a file keys/jake and add any number of keys in the that file. All these keys will be treated as Jake's key

Organizing server list

• Create a file called servers.js which should export an array of objects
• Each object can have the following properties
  • host: hostname or IP addreess
  • name: A name to indentify the server.
  • port: Port number ( Optional. default 22 )
  • user: ssh user ( Optional : default: devuser )

Eg

module.exports = [
    {
      name: 'app1Dev',
      host: '8.8.8.8',
    },
    {
      name: 'app1Staging',
      host: '8.8.8.9',
    },
];

Adding removing ssh keys

CLI interface

1. list currently loaded server names and usernames

npx ssh-access-manager -a

2. list status of all servers.

npx ssh-access-manager -l

3. grant access to username 'jake' on server called 'devserver'

npx ssh-access-manager -n devserver -g jake

4. set access of server 'devserver' to user 'jake' only

npx ssh-access-manager -n devserver -s jake

5. revoke access to username 'jake' on server called 'devserver'

npx ssh-access-manager -n devserver -r jake

5. Dump curret Access-Control-List ( ACL ) for servers. ( Ie, simply dump output of -l command as json )

npx ssh-access-manager -l -j

6. Update server access from acl.js file.

npx ssh-access-manager -U

We can create a acl.js file by simply dumping current state in all the servers.

npx ssh-access-manager -l -j >> acl.json

API usage

var server = new Server( [ 'devuser@8.8.8.8', 1122 ] );

// list the usernames in the server
server.listAccess(); // -> Promise( Array<String> )

server.grantAccess( 'hari' ); // -> Promise( Array<String> )

server.revokeAccess( 'hari' ); // -> Promise( Array<String> )

server.setAccess( 'hari' ); // -> Promise( Array<String> )
