SSHMon is a program designed to manage and monitor ssh connections. It has been tested on Linux and OSX with SSH ≥ 6.7.

SSHMon builds on top of the SSH "Control Master" feature, that facilitates port forwarding setup.

• SSHMon Features (e.g. SSH host definition and connection) are exposed through the GUI. As a consequence, extreme care should be taken to make sure it is only reachable by you. Use at your own risk.
• SSHMon is still at an early stage of development, as a result some things might not work and we might introduce some breaking changes... Any feedback will be greatly appreciated!

• Nice GUI
• SSH port/socket forwarding management
• Configuration with YAML file
• Automatic start and retry of connection and port forwarding
• HTTP forwarding

Download the latest release of SSHMon for your system and unpack it. Run the sshmon binary:

./sshmon

Then you can access the web GUI at https://localhost:8377.

Go and have a look at the Tutorial to set up your first host!

yarn
yarn build
yarn start

You can set up SSH connections through the GUI or with a configuration file.

By default, SSHMon will create a config file located at ~/.sshmon/config.yml. You also may specify your own configuration file on the command line.

Head over to the Configuration page for more details.

Logging is handled by the bunyan library. A bunyan process is launched along with SSHMon and writes logs to stderr.

By default, if stderr is a TTY, the logs are pretty-printed, else they are written in a JSON format. You may use the BUNYAN_OPTS environment variable to choose which args are passed to the bunyan process, e.g.:

BUNYAN_OPTS='-l debug' ./sshmon

Docker and docker-compose are required.

You may run the test suite with:

yarn test

• So far, only public/private key authentication is supported.
• Before trying to connect to a host through SSHMon, make sure you can connect to it with SSH on the command line.

SSHMon was developped thanks to the following projects (this list is not exhaustive!):

• TypeScript
• React
• Redux
• Bulma
• Bulmaswatch
• Socket.IO
• Bunyan
• pkg

• Allow to change GUI address
• Offer multiple GUI themes
• Allow custom global SSH config options
• Use BatchMode for ProxyJump SSH hosts
