It seems that Firefox is rejecting the connection before it even gets to the destination web server. I am trying this now with my virtual server at isbd.uk. I am setting up the ssh proxy from my desktop machine as follows:- ssh -fTnN -D 1080 chris@xxxxxxx I configure Firefox to use the proxy and when I try and connect I get the security failure. However there is no connection at all that reaches the apache2 web server at isbd.uk, thus Firefox is rejecting the connection because of something it doesn't like in the ssh tunnel. Is it possible that it's somehow checking if there's a certificate for my desktop machine that's running the ssh proxy command? Is there any way to debug what's going on between Firefox and the ssh tunnel? Adding -vvv to the ssh proxy command tells me very little except that there's lots of activity! :-) -- Chris Green _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
