+\S{faq-savedsettings}{Question} Does PuTTY support storing settings,

present time. If anyone told you we had an EPOC port, or an iPaq port,
or any other port of PuTTY, they were mistaken. We don't.
+There are some third-party ports to various platforms, mentioned
+on the Links page of our website.

\S{faq-unix}{Question} Is there a port to Unix?
As of 0.54, there are Unix ports of most of the traditional PuTTY
clearly be a useful thing, so in the long term I hope it can be
brought up to release quality.
+There's also a third-party port at

\S{faq-win31}{Question} Is there a port to Windows 3.1?
PuTTY is a 32-bit application from the ground up, so it won't run on
There is a port to the Mac OS in progress. It's just about usable, but
has an awful lot of gaps and rough edges that will need cleaning up

+A separate port to Mac OS X is also underway.

-\S{faq-rekey}{Question} My PuTTY sessions close after an hour and
-tell me \q{Server failed host key check}.
-
-This is a bug in all versions of PuTTY up to and including 0.51. SSH
-v2 servers from \cw{ssh.com} will require the key exchange to be
-repeated one hour after the start of the connection, and PuTTY will
-get this wrong.
-
-Upgrade to version 0.52 or better and the problem should go away.
-
\S{faq-outofmem}{Question} After trying to establish an SSH 2
connection, PuTTY says \q{Out of memory} and dies.
In version 0.54, the behaviour has changed - changes to these
settings take effect immediately.
-\S{faq-altgr}{Question} I can't type characters that require the
-AltGr key.
-
-In PuTTY version 0.51, the AltGr key was broken. Upgrade to version
-0.52 or better.

\S{faq-idleout}{Question} My PuTTY sessions unexpectedly close after
they are idle for a while.
way we did - by being good enough at what you do that people will
link to you simply because they like you.
+In particular, we aren't interested in trading links for money (see
+above), and we \e{certainly} aren't interested in trading links for
+other links (since we have no advertising on our web site, our
+Google ranking is not even directly worth anything to us). If we
+don't want to link to you for free, then we probably won't want to
+link to you at all.
+
If you have software based on PuTTY, or specifically designed to
interoperate with PuTTY, or in some other way of genuine interest to
PuTTY users, then we will probably be happy to add a link to you on
Having said all that, if you still really \e{want} to give us money,
we won't argue :-) The easiest way for us to accept donations is if
-you go to \W{http://www.e-gold.com}\cw{www.e-gold.com}, and deposit
-your donation in account number 174769. Then send us e-mail to let
-us know you've done so (otherwise we might not notice for months!).
-Alternatively, if e-gold isn't convenient for you, you can donate to
-\cw{<anakin@pobox.com>} using PayPal
-(\W{http://www.paypal.com/}\cw{www.paypal.com}).
+you send money to \cw{<anakin@pobox.com>} using PayPal
+(\W{http://www.paypal.com/}\cw{www.paypal.com}). Alternatively, if
+you don't trust PayPal, you could donate through e-gold
+(\W{http://www.e-gold.com}\cw{www.e-gold.com}): deposit your
+donation in account number 174769, then send us e-mail to let us
+know you've done so (otherwise we might not notice for months!).
Small donations (tens of dollars or tens of euros) will probably be
spent on beer or curry, which helps motivate our volunteer team to
something worthwhile, ask us first. If you don't like these terms,
feel perfectly free not to donate. We don't mind.
+\S{faq-permission}{Question} Can I have permission to put PuTTY on a
+cover disk / distribute it with other software / etc?
+
+Yes. You need not bother asking us explicitly for permission. You
+already have permission. Redistribution of the unmodified PuTTY
+binary in this way is entirely permitted by our licence, and you are
+welcome to do it as much as you like.
+
+If you are distributing PuTTY within your own organisation, or for
+use with your own product, then we recommend (but do not insist)
+that you offer your own first-line technical support, to answer
+questions directly relating to the interaction of PuTTY with your
+particular environment. If your users mail us directly, we won't be
+able to give them very much help about things specific to your own
+setup.
