A Plink invocation of the form 'plink -shareexists <session>' tests for a currently live connection-sharing upstream for the session in question. <session> can be any syntax you'd use with Plink to make the actual connection (a host/port number, a bare saved session name, -load, whatever). I envisage this being useful for things like adaptive proxying - e.g. if you want to connect to host A which you can't route to directly, and you might already have a connection to either of hosts B or C which are viable proxies, then you could write a proxy shell script which checks whether you already have an upstream for B or C and goes via whichever one is currently active. Testing for the upstream's existence has to be done by actually connecting to its socket, because on Unix the mere existence of a Unix-domain socket file doesn't guarantee that there's a process listening to it. So we make a test connection, and then immediately disconnect; hence, that shows up in the upstream's event log. |

PuTTY README
============
This is the README file for the PuTTY installer distribution. If
you're reading this, you've probably just run our installer and
installed PuTTY on your system.
What should I do next?
----------------------
If you want to use PuTTY to connect to other computers, or use PSFTP
to transfer files, you should just be able to run them from the
Start menu.
If you want to use the command-line-only file transfer utility PSCP,
you will probably want to put the PuTTY installation directory on
your PATH. On Windows 7 and similar versions, you can do this at
Control Panel > System and Security > System > Advanced system
settings > Environment Variables.
Some versions of Windows will refuse to run HTML Help files (.CHM)
if they are installed on a network drive. If you have installed
PuTTY on a network drive, you might want to check that the help file
works properly. If not, see http://support.microsoft.com/kb/896054
for information on how to solve this problem.
What do I do if it doesn't work?
--------------------------------
The PuTTY home web site is
http://www.chiark.greenend.org.uk/~sgtatham/putty/
Here you will find our list of known bugs and pending feature
requests. If your problem is not listed in there, or in the FAQ, or
in the manuals, read the Feedback page to find out how to report
bugs to us. PLEASE read the Feedback page carefully: it is there to
save you time as well as us. Do not send us one-line bug reports
telling us `it doesn't work'.
