plink - PuTTY link, command line network connection tool
plink [options] [user@]host [command]
plink is a network connection tool supporting several protocols.
The command-line options supported by plink are: -V Show version information and exit. -pgpfp Display the fingerprints of the PuTTY PGP Master Keys and exit, to aid in verifying new files released by the PuTTY team. -v Show verbose messages. -load session Load settings from saved session. -ssh Force use of SSH protocol (default). -telnet Force use of Telnet protocol. -rlogin Force use of rlogin protocol. -raw Force raw mode. -serial Force serial mode. -proxycmd command Instead of making a TCP connection, use command as a proxy; network traffic will be redirected to the standard input and output of command. command must be a single word, so is likely to need quoting by the shell. The special strings %host and %port in command will be replaced by the hostname and port number you want to connect to; to get a literal % sign, enter %%. Backslash escapes are also supported, such as sequences like \n being replaced by a literal newline; to get a literal backslash, enter \\. (Further escaping may be required by the shell.) (See the main PuTTY manual for full details of the supported %- and backslash- delimited tokens, although most of them are probably not very useful in this context.) -P port Connect to port port. -l user Set remote username to user. -m path Read remote command(s) from local file path. -batch Disable interactive prompts. -pw password Set remote password to password. CAUTION: this will likely make the password visible to other users of the local machine (via commands such as `w'). -L [srcaddr:]srcport:desthost:destport Set up a local port forwarding: listen on srcport (or srcaddr:srcport if specified), and forward any connections over the SSH connection to the destination address desthost:destport. Only works in SSH. -R [srcaddr:]srcport:desthost:destport Set up a remote port forwarding: ask the SSH server to listen on srcport (or srcaddr:srcport if specified), and to forward any connections back over the SSH connection where the client will pass them on to the destination address desthost:destport. Only works in SSH. -D [srcaddr:]srcport Set up dynamic port forwarding. The client listens on srcport (or srcaddr:srcport if specified), and implements a SOCKS server. So you can point SOCKS-aware applications at this port and they will automatically use the SSH connection to tunnel all their connections. Only works in SSH. -X Enable X11 forwarding. -x Disable X11 forwarding (default). -A Enable agent forwarding. -a Disable agent forwarding (default). -t Enable pty allocation (default if a command is NOT specified). -T Disable pty allocation (default if a command is specified). -1 Force use of SSH protocol version 1. -2 Force use of SSH protocol version 2. -4, -6 Force use of IPv4 or IPv6 for network connections. -C Enable SSH compression. -i keyfile Private key file for user authentication. For SSH-2 keys, this key file must be in PuTTY's PPK format, not OpenSSH's format or anyone else's. If you are using an authentication agent, you can also specify a public key here (in RFC 4716 or OpenSSH format), to identify which of the agent's keys to use. -noagent Don't try to use an authentication agent for local authentication. (This doesn't affect agent forwarding.) -agent Allow use of an authentication agent. (This option is only necessary to override a setting in a saved session.) -hostkey key Specify an acceptable host public key. This option may be specified multiple times; each key can be either a fingerprint (99:aa:bb:...) or a base64-encoded blob in OpenSSH's one-line format. Specifying this option overrides automated host key management; only the key(s) specified on the command-line will be accepted (unless a saved session also overrides host keys, in which case those will be added to), and the host key cache will not be written. -s Remote command is SSH subsystem (SSH-2 only). -N Don't start a remote command or shell at all (SSH-2 only). -nc host:port Make a remote network connection from the server instead of starting a shell or command. -sercfg configuration-string Specify the configuration parameters for the serial port, in -serial mode. configuration-string should be a comma-separated list of configuration parameters as follows: · Any single digit from 5 to 9 sets the number of data bits. · `1', `1.5' or `2' sets the number of stop bits. · Any other numeric string is interpreted as a baud rate. · A single lower-case letter specifies the parity: `n' for none, `o' for odd, `e' for even, `m' for mark and `s' for space. · A single upper-case letter specifies the flow control: `N' for none, `X' for XON/XOFF, `R' for RTS/CTS and `D' for DSR/DTR. -sshlog logfile -sshrawlog logfile For SSH connections, these options make plink log protocol details to a file. (Some of these may be sensitive, although by default an effort is made to suppress obvious passwords.) -sshlog logs decoded SSH packets and other events (those that -v would print). -sshrawlog additionally logs the raw encrypted packet data. -shareexists Instead of making a new connection, test for the presence of an existing connection that can be shared. The desired session can be specified in any of the usual ways. Returns immediately with a zero exit status if a suitable `upstream' exists, nonzero otherwise.
For more information on plink, it's probably best to go and look at the manual on the PuTTY web page: https://www.chiark.greenend.org.uk/~sgtatham/putty/
This man page isn't terribly complete. See the above web link for better documentation.
