From time to time a file called "PUTTY.RND" mysteriously appears in my
personal folder and the time stamp always coincides with time stamps of
entries (changes) in my Mozilla/Firefox app data. Can anyone explain
what kind of file this is and whether it is actually connected with
Firefox? At least deleting this file doesn't cause any troubles as far
as I see.
Thanks

In article <_eSdncyx_qyRhT3X...@mozilla.org>,

AFAIK it's generated by the pseudo-random number generator which the
open-source telnet application PuTTY uses for encryption keys. Is PuTTY
set to be your default telnet client perhaps?

Thank you for your reply. But the links you offer (which I also found on
the Web) don't really lead me anywhere. "PUTTY.RND" (no entries in the
registry point to it) seems to be a pretty isolated file (unsuspicious
to Avast, Spybot and Spyware Terminator) which only seems to be linked
to files & folders in my Mozilla/Firefox app data.
Is there any known interdependence between Firefox and "PUTTY.RND"?

The links should have give you a hint that some applications on your
machine use putty as a component. Mozilla is not one of those
applications. Maybe some extensions. Delete the file then start Firefox
in safe mode to see if it recreates.

I am certainly no expert on this but it would seem to me that from the
description of PUTTY.RND, it is only generated by running puTTY
software. As you have run virus/malware scanners on that particular file
and it has been given a clean bill of health, my gut reaction would be
to assume (for now) it's not a bogus file and therefore has been
generated by putty software.

PuTTY is a client program for the SSH, Telnet and Rlogin network
protocols.These protocols are all used to run a remote session on a
computer, over a network.

Is puTTY installed on your system?
Have you been using/experimenting with SSH, tunneling, proxies etc as
per this following minor example:

http://72.167.30.61/unix/edu/putty-ssh-tunnel-firefox-socks-proxy/4-test-firefox-socks-proxy-putty-ssh-tunnel.shtml

Any other apps that would be utilizing puTTY, and that you have used in
congunction with Firefox, installed on your system?

As previously stated, I am certainly no expert on this sofware, but
these are the kinds of questions/scenario's I would be considering if
trying to troubleshoot this kind of "problem". :-)

Thank you (and LU Wei in the preceding mail) for your really helpful
suggestions which gave me the decisive hint: this putty.rnd file was
created whenever I experimented with the firefox version of UltraSurf.
So "this kind of 'problem'" has found a satisfactory answer. :-)

Good to hear, rebro....thanks for the update! Never heard of Ultrasurf
before so your mention of it is greatly appreciated. :-)

In fact my first guess is Ultrasurf, for I use it too. Are you from
China mainland? If not, Please don't waste the valuable bandwidth of the
network that help us bypass the censorship of government. You really
don't need encrypted proxy in USA. If you are concerned about anonymity,
try Tor. Ultrasurf is not intended to protect your anonymity -- anyway
your data is on their server -- its target is to help chinese people
surfing internet freely regardless of the Great Firewall.

Guys,

Thank you for this thread. I was having the same concern about a
PUTTY.RND file showing up on my system, but I'm now content after
finding this discussion via Google.

Thanks very much,
T.

A lot of Canadian and American students use UltraSurf to get past the blocker systems at school.

Well, putty.rnd is actually used for SSH+ connections (great for kiddies to dodge school internet blocking software). However, there may be a chance of something using it for malware, so be wary.
