The tunnel will automatically close when not in use, remaining open for a minimum of timeout seconds for an initial connection. This creates a tunnel redirecting `localhost:lport` to `remoteip:rport`, as seen from `server`. keyfile and password may be specified, but ssh config is checked for defaults. Parameters ---------- lport : int local port for connecting to the tunnel from this machine. rport : int port on the remote machine to connect to. server : str The ssh server to connect to. The full ssh server string will be parsed. user@server:port remoteip : str [Default: 127.0.0.1] The remote ip, specifying the destination of the tunnel. Default is localhost, which means that the tunnel would redirect localhost:lport on this machine to localhost:rport on the *server*. keyfile : str; path to private key file This specifies a key to be used in ssh login, default None. Regular default ssh keys will be used without specifying this argument. password : str; Your ssh password to the ssh server. Note that if this is left None, you will be prompted for it if passwordless key based login is unavailable. timeout : int [default: 60] The time (in seconds) after which no activity will result in the tunnel closing. This prevents orphaned tunnels from running forever.

This should only be used when shell ssh is unavailable (e.g. Windows). This creates a tunnel redirecting `localhost:lport` to `remoteip:rport`, as seen from `server`. If you are familiar with ssh tunnels, this creates the tunnel: ssh server -L localhost:lport:remoteip:rport keyfile and password may be specified, but ssh config is checked for defaults. Parameters ---------- lport : int local port for connecting to the tunnel from this machine. rport : int port on the remote machine to connect to. server : str The ssh server to connect to. The full ssh server string will be parsed. user@server:port remoteip : str [Default: 127.0.0.1] The remote ip, specifying the destination of the tunnel. Default is localhost, which means that the tunnel would redirect localhost:lport on this machine to localhost:rport on the *server*. keyfile : str; path to private key file This specifies a key to be used in ssh login, default None. Regular default ssh keys will be used without specifying this argument. password : str; Your ssh password to the ssh server. Note that if this is left None, you will be prompted for it if passwordless key based login is unavailable. timeout : int [default: 60] The time (in seconds) after which no activity will result in the tunnel closing.
