KHM - Known Hosts Manager

KHM allows you to synchronize the known_hosts file across multiple hosts. This application manages SSH keys and flows, either as a server or client. In server mode, it stores keys and flows in a PostgreSQL database. In client mode, it sends keys to the server and can update the known_hosts file with keys from the server.

Features

• Synchronize known_hosts file across multiple hosts.
• Manage SSH keys and flows in a PostgreSQL database.
• Operate in both server and client modes.
• Automatically update known_hosts file with keys from the server.

Usage

Server Mode

To run the application in server mode, use the following command:

khm --server --ip 127.0.0.1 --port 8080 --db-host 127.0.0.1 --db-name khm --db-user admin --db-password <SECRET> --flows work,home

Client Mode

To run the application in client mode, use the following command:

khm --host http://khm.example.com:8080/<FLOW_NAME>/ --known-hosts ~/.ssh/known_hosts --in-place
