-As an example, the other day I installed [Grafana](TK){target="_blank" rel="noreferrer"} on a Linux server in the cloud. To quickly view the web UI on my local machine I can use `ssh` with the `-L` option to forward a local port to the Grafana port (default: 3000) on my server
-```
-ssh -L 3000:server:3000 server
-```
-
-Navigating to localhost:3000 in my browser gives me access to Grafana. This is great except I have to leave a terminal open for the `ssh` session. Adding the `-N` option tells `ssh` not to run a remote command, if you try this the connection will open but you won't get a prompt on the server. Also adding the `-f` option puts `ssh` into the background, freeing up the terminal
-```
-ssh -NfL 3000:server:3000 server
-```
-
-In order to close the connection you will have to find the PID then kill it. Not very eloquent. My preference is to use the `ControlMaster` option in my ~/.ssh/config, something that I use for sharing `ssh` connections (see my [ssh-aring is caring](20220116-ssh-aring_is_caring.html){target="_blank" rel="noreferrer"} post).
-
-By adding the `ControlMaster` and `ControlPath` options into ~/.ssh/config allows `ssh` to manage these connections. You can use the `-O` option to pass control commands (`ctl_cmds`)
-```
-ssh -O check server
-Master running (pid=1511266)
-```
-
-You can also look in the path specified by `ControlPath` to see the sockets. Closing the background connection is now clean and tidy
-```
-ssh -O exit server
-```
-
-For port forwarding connections that I use regularly I add the options into ~/.ssh/config, making my life easier. For the example above I would add
-```
-Host server
- HostName server
- LocalForward 3000 server:3000
- ForkAfterAuthentication yes
- SessionType none
-```
-
-Now I can incant
-```
-ssh server
-```
-
-This opens the connection and puts it into the background allowing me to continue with my local terminal session and view Grafana on my remote server.
