14 \S{plink-manpage-description} DESCRIPTION
16 \cw{plink} is a network connection tool supporting several protocols.
18 \S{plink-manpage-options} OPTIONS
20 The command-line options supported by \cw{plink} are:
24 \dd Show version information and exit.
28 \dd Display the fingerprints of the PuTTY PGP Master Keys and exit,
29 to aid in verifying new files released by the PuTTY team.
33 \dd Show verbose messages.
35 \dt \cw{-load} \e{session}
37 \dd Load settings from saved session.
41 \dd Force use of SSH protocol (default).
45 \dd Force use of Telnet protocol.
49 \dd Force use of rlogin protocol.
57 \dd Force serial mode.
61 \dd Connect to port \e{port}.
65 \dd Set remote username to \e{user}.
69 \dd Read remote command(s) from local file \e{path}.
73 \dd Disable interactive prompts.
75 \dt \cw{-pw} \e{password}
77 \dd Set remote password to \e{password}. \e{CAUTION:} this will likely
78 make the password visible to other users of the local machine (via
79 commands such as \q{\c{w}}).
81 \dt \cw{\-L} \cw{[}\e{srcaddr}\cw{:]}\e{srcport}\cw{:}\e{desthost}\cw{:}\e{destport}
83 \dd Set up a local port forwarding: listen on \e{srcport} (or
84 \e{srcaddr}:\e{srcport} if specified), and forward any connections
85 over the SSH connection to the destination address
86 \e{desthost}:\e{destport}. Only works in SSH.
88 \dt \cw{\-R} \cw{[}\e{srcaddr}\cw{:]}\e{srcport}\cw{:}\e{desthost}\cw{:}\e{destport}
90 \dd Set up a remote port forwarding: ask the SSH server to listen on
91 \e{srcport} (or \e{srcaddr}:\e{srcport} if specified), and to
92 forward any connections back over the SSH connection where the
93 client will pass them on to the destination address
94 \e{desthost}:\e{destport}. Only works in SSH.
96 \dt \cw{\-D} [\e{srcaddr}:]\e{srcport}
98 \dd Set up dynamic port forwarding. The client listens on
99 \e{srcport} (or \e{srcaddr}:\e{srcport} if specified), and
100 implements a SOCKS server. So you can point SOCKS-aware applications
101 at this port and they will automatically use the SSH connection to
102 tunnel all their connections. Only works in SSH.
106 \dd Enable X11 forwarding.
110 \dd Disable X11 forwarding (default).
114 \dd Enable agent forwarding.
118 \dd Disable agent forwarding (default).
122 \dd Enable pty allocation (default if a command is NOT specified).
126 \dd Disable pty allocation (default if a command is specified).
130 \dd Force use of SSH protocol version 1.
134 \dd Force use of SSH protocol version 2.
138 \dd Force use of IPv4 or IPv6 for network connections.
142 \dd Enable SSH compression.
144 \dt \cw{-i} \e{keyfile}
146 \dd Private key file for user authentication. For SSH-2 keys, this key
147 file must be in PuTTY's PPK format, not OpenSSH's format or anyone
150 \lcont{ If you are using an authentication agent, you can also specify
151 a \e{public} key here (in RFC 4716 or OpenSSH format), to identify
152 which of the agent's keys to use. }
156 \dd Don't try to use an authentication agent for local authentication.
157 (This doesn't affect agent forwarding.)
161 \dd Allow use of an authentication agent. (This option is only necessary
162 to override a setting in a saved session.)
164 \dt \cw{\-hostkey} \e{key}
166 \dd Specify an acceptable host public key. This option may be specified
167 multiple times; each key can be either a fingerprint (\cw{99:aa:bb:...}) or
168 a base64-encoded blob in OpenSSH's one-line format.
170 \lcont{ Specifying this option overrides automated host key
171 management; \e{only} the key(s) specified on the command-line will be
172 accepted (unless a saved session also overrides host keys, in which
173 case those will be added to), and the host key cache will not be
178 \dd Remote command is SSH subsystem (SSH-2 only).
182 \dd Don't start a remote command or shell at all (SSH-2 only).
184 \dt \cw{\-nc} \e{host}:\e{port}
186 \dd Make a remote network connection from the server instead of
187 starting a shell or command.
189 \dt \cw{\-sercfg} \e{configuration-string}
191 \dd Specify the configuration parameters for the serial port, in
192 \cw{-serial} mode. \e{configuration-string} should be a
193 comma-separated list of configuration parameters as follows:
197 \b Any single digit from 5 to 9 sets the number of data bits.
199 \b \cq{1}, \cq{1.5} or \cq{2} sets the number of stop bits.
201 \b Any other numeric string is interpreted as a baud rate.
203 \b A single lower-case letter specifies the parity: \cq{n} for none,
204 \cq{o} for odd, \cq{e} for even, \cq{m} for mark and \cq{s} for space.
206 \b A single upper-case letter specifies the flow control: \cq{N} for
207 none, \cq{X} for XON/XOFF, \cq{R} for RTS/CTS and \cq{D} for
212 \dt \cw{\-sshlog} \e{logfile}
214 \dt \cw{\-sshrawlog} \e{logfile}
216 \dd For SSH connections, these options make \cw{plink} log protocol
217 details to a file. (Some of these may be sensitive, although by default
218 an effort is made to suppress obvious passwords.)
221 \cw{\-sshlog} logs decoded SSH packets and other events (those that
222 \cw{\-v} would print). \cw{\-sshrawlog} additionally logs the raw
223 encrypted packet data.
226 \dt \cw{\-shareexists}
228 \dd Instead of making a new connection, test for the presence of an
229 existing connection that can be shared. The desired session can be
230 specified in any of the usual ways.
233 Returns immediately with a zero exit status if a suitable \q{upstream}
234 exists, nonzero otherwise.
