sshapp

sshapp allows you to run an application when a user uses ssh to connect to your server.

The default port is 2222 you can change the port by using sshapp --port 2245 --cmd "app-to-execute"

Running with SystemD

If you want to run sshapp with systemd, you can create a unit like so:

/etc/systemd/system/myapp.service:

[Unit]
Description=My App
After=network.target

[Service]
Type=simple
User=myapp
Group=myapp
WorkingDirectory=/home/myapp/bin/
ExecStart=/home/myapp/bin/sshapp --port 2222 --cmd "app-to-execute"
Restart=on-failure

[Install]
WantedBy=multi-user.target

To make the service run via SystemD

# need to run this every time you change the unit file
sudo systemctl daemon-reload

# start/restart/stop/etc:
sudo systemctl start myapp

# to load the sshapp server when the server boots/reboots
sudo systemctl enable myapp
