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).

Force use of Telnet protocol.

Force use of rlogin protocol.

-raw Force raw mode.

Force serial mode.

-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.

-C Enable SSH compression.

-i path
Private key file for user authentication.

-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).

-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.


For more information on plink, it's probably best to go and look at the manual on the
