-## NAME
-podman\-system\-connection - Record ssh destination for remote podman service
-
-## SYNOPSIS
-**podman system connection** [*options*] [*ssh destination*]
-
-## DESCRIPTION
-Record ssh destination for remote podman service(s). The ssh destination is given as one of:
- - [user@]hostname[:port]
- - ssh://[user@]hostname[:port]
-
-The user will be prompted for the remote ssh login password or key file pass phrase as required. `ssh-agent` is supported if it is running.
-
-## OPTIONS
-
-**-p**, **--port**=*port*
-
-Port for ssh destination. The default value is `22`.
-
-**--socket-path**=*path*
-
-Path to podman service unix domain socket on the ssh destination host
-
-## EXAMPLE
-```
-$ podman system connection podman.fubar.com
-
-$ podman system connection --identity ~/.ssh/dev_rsa ssh://root@server.fubar.com:2222
-
-```
