\C{config} Configuring PuTTY
very specialist purposes; although in Plink (see \k{plink}) it is
the usual way of working.
+\S{config-ssh-noshell} \q{Don't start a shell or command at all}
+
+\cfg{winhelp-topic}{ssh.noshell}
+
+If you tick this box, PuTTY will not attempt to run a shell or
+command after connecting to the remote server. You might want to use
+this option if you are only using the SSH connection for port
+forwarding, and your user account on the server does not have the
+ability to run a shell.
+
+This feature is only available in SSH protocol version 2 (since the
+version 1 protocol assumes you will always want to run a shell).
+
+This feature can also be enabled using the \c{-N} command-line
+option; see \k{using-cmdline-noshell}.
+
+If you use this feature in Plink, you will not be able to terminate
+the Plink process by any graceful means; the only way to kill it
+will be by pressing Control-C or sending a kill signal from another
+program.

\S{config-ssh-comp} \q{Enable compression}
\cfg{winhelp-topic}{ssh.compress}
a local X display on your PC.
To enable X11 forwarding, check the \q{Enable X11 forwarding} box.
-If your X display is not the primary display on your local machine
-(which it almost certainly will be unless you have deliberately
-arranged otherwise), you need to enter its location in the \q{X
-display location} box.
+If your X display is somewhere unusual, you will need to enter its
+location in the \q{X display location} box; if this is left blank,
+PuTTY try to find a sensible default in the environment, or use the
+primary local display (\c{:0}) if that fails.
See \k{using-x-forwarding} for more information about X11
forwarding.
