Well, you could help convince yourself one way or the other by uninstalling ZoneAlarm for the purposes of testing and try the failing scenario again. -- Larry Hall http://www.rfk.com RFK Partners, Inc.

Re: SSH X11 forwarding issues (with verbose data)
Hi Jack. ssh -Y ended up with me doing the following: $ /usr/X11R6/bin/xauth list 127.0.0.1:0.0 /usr/X11R6/bin/xauth: creating new authority file /home/phil/.Xauthority Nothing happened on the other xterm window, so I went looking for /home/phil/.Xauthority - it didn't exist! (yes, I typed ls -a) :) So I tried ssh -X ... and ended up with me doing the following: $ /usr/X11R6/bin/xauth -f /tmp/ssh-Q7ut6XsxFY/xauthfile generate 127.0.0.1:0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 /usr/X11R6/bin/xauth: creating new authority file /tmp/ssh-Q7ut6XsxFY/xauthfile now a file called "xauthfile" was created in that directory, and its contents were: 0MIT-MAGIC-COOKIE-1&<12 character long pseudorandom string> But still, no movement on the xterm window. Here's the oddity: Why could I just start the Cygwin/X server and run putty for windows with X11 forwarding and it'll work just fine? Why would X-Win32 with its built-in StarnetSSH client work just fine completely on its own?
