SYNOPSISputty [ options ] [ host ]
DESCRIPTIONputty is a graphical SSH, Telnet and Rlogin client for X. It is a
direct port of the Windows SSH client of the same name.
OPTIONS
The command-line options supported by putty are:
--display display-name
Specify the X display on which to open putty. (Note this option
has a double minus sign, even though none of the others do. This
is because this option is supplied automatically by GTK. Sorry.)
-fn font-name
Specify the font to use for normal text displayed in the termi‐
nal.
-fb font-name
Specify the font to use for bold text displayed in the terminal.
If the BoldAsColour resource is set to 1 (the default), bold
text will be displayed in different colours instead of a differ‐
ent font, so this option will be ignored. If BoldAsColour is set
to 0 or 2 and you do not specify a bold font, putty will over‐
print the normal font to make it look bolder.
-fw font-name
Specify the font to use for double-width characters (typically
Chinese, Japanese and Korean text) displayed in the terminal.
-fwb font-name
Specify the font to use for bold double-width characters (typi‐
cally Chinese, Japanese and Korean text). Like -fb, this will be
ignored unless the BoldAsColour resource is set to 0 or 2.
-geometry geometry
Specify the size of the terminal, in rows and columns of text.
See X(7) for more information on the syntax of geometry specifi‐
cations.
-sl lines
Specify the number of lines of scrollback to save off the top of
the terminal.
-fg colour
Specify the foreground colour to use for normal text.
-bg colour
Specify the background colour to use for normal text.
-bfg colour
Specify the foreground colour to use for bold text, if the
BoldAsColour resource is set to 1 (the default) or 2.
-bbg colour
Specify the foreground colour to use for bold reverse-video
text, if the BoldAsColour resource is set to 1 (the default) or
2. (This colour is best thought of as the bold version of the
background colour; so it only appears when text is displayed in
the background colour.)
-cfg colour
Specify the foreground colour to use for text covered by the
cursor.
-cbg colour
Specify the background colour to use for text covered by the
cursor. In other words, this is the main colour of the cursor.
-title title
Specify the initial title of the terminal window. (This can be
changed under control of the server.)
-sb- or +sb
Tells putty not to display a scroll bar.
-sb Tells putty to display a scroll bar: this is the opposite of
-sb-. This is the default option: you will probably only need to
specify it explicitly if you have changed the default using the
ScrollBar resource.
-log filename
This option makes putty log all the terminal output to a file as
well as displaying it in the terminal.
-cs charset
This option specifies the character set in which putty should
assume the session is operating. This character set will be used
to interpret all the data received from the session, and all
input you type or paste into putty will be converted into this
character set before being sent to the session.
Any character set name which is valid in a MIME header (and sup‐
ported by putty) should be valid here (examples are
`ISO-8859-1', `windows-1252' or `UTF-8'). Also, any character
encoding which is valid in an X logical font description should
be valid (`ibm-cp437', for example).
putty's default behaviour is to use the same character encoding
as its primary font. If you supply a Unicode (iso10646-1) font,
it will default to the UTF-8 character set.
Character set names are case-insensitive.
-nethack
Tells putty to enable NetHack keypad mode, in which the numeric
keypad generates the NetHack hjklyubn direction keys. This
enables you to play NetHack with the numeric keypad without hav‐
ing to use the NetHack number_pad option (which requires you to
press `n' before any repeat count). So you can move with the
numeric keypad, and enter repeat counts with the normal number
keys.
-help, --help
Display a message summarizing the available options.
-pgpfp Display the fingerprints of the PuTTY PGP Master Keys, to aid in
verifying new files released by the PuTTY team.
-load session
Load a saved session by name. This allows you to run a saved
session straight from the command line without having to go
through the configuration box first.
-ssh, -telnet, -rlogin, -raw, -serial
Select the protocol putty will use to make the connection.
-l username
Specify the username to use when logging in to the server.
-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.
-P port
Specify the port to connect to the server on.
-A, -a Enable (-A) or disable (-a) SSH agent forwarding. Currently this
only works with OpenSSH and SSH-1.
-X, -x Enable (-X) or disable (-x) X11 forwarding.
-T, -t Enable (-t) or disable (-T) the allocation of a pseudo-terminal
at the server end.
-C Enable zlib-style compression on the connection.
-1, -2 Select SSH protocol version 1 or 2.
-i keyfile
Specify a private key file to use for user authentication. For
SSH-2 keys, this key file must be in PuTTY's format, not
OpenSSH's or anyone else's.
-hostkey key
Specify an acceptable host public key. This option may be speci‐
fied 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.
-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.
SAVED SESSIONS
Saved sessions are stored in a .putty/sessions subdirectory in your
home directory.
