Connect to a remote server:

mosh {{username}}@{{remote_host}}

Connect to a remote server with a specific identity (private key):

mosh --ssh="ssh -i {{path/to/key_file}}" {{username}}@{{remote_host}}

Connect to a remote server using a specific port:

mosh --ssh="ssh -p {{2222}}" {{username}}@{{remote_host}}

Run a command on a remote server:

mosh {{remote_host}} -- {{command -with -flags}}

Select Mosh UDP port (useful when remote_host is behind a NAT):

mosh -p {{124}} {{username}}@{{remote_host}}

mosh --server={{path/to/mosh-server}} {{remote_host}}
