NAME
plink - PuTTY link, command line network connection tool
SYNOPSIS
plink [options] [user@]host [command]
DESCRIPTION
plink is a network connection tool supporting several protocols.
OPTIONS
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.
