PuTTY uses a different command line syntax and case is important: http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter3.html#using-gen eral-opts Mark Lavi Senior Web Producer sgi 46600 Landing Parkway Fremont, CA 94538 (510) 933-5234 direct mlavi@xxxxxxx www.sgi.com -----Original Message----- From: listbounce@xxxxxxxxxxxxxxxxx [mailto:listbounce@xxxxxxxxxxxxxxxxx] On Behalf Of Al Grant Sent: Monday, December 27, 2010 2:04 AM To: secureshell@xxxxxxxxxxxxxxxxx Subject: Putty; Win7; IE8 Hi All, I REALLY hope someone here can help me. I have been trying to setup a SSH tunnel so that when I surf the net on my laptop I can SSH into my Ubuntu box at home and go through that for web page traffic. Now I tried to connect to Ubuntu@home from laptop running Win7 with: putty -ssh my.dyndns.org -l username -P 443 -D 8080 -v and the connection establishes just fine, but when I surf to whatsmyip.org I get a different WAN IP to my Ubuntu WAN IP. Weird, so after a lot or trying different things (IE7, Chrome etc) I rebooted that same laptop into Ubuntu as well and issued the exact same command but not using putty ssh my.dyndns.org -l username -P 443 -D 8080 -v Now it works like a charm, so I am thinking its something specific to Win7 or Putty. But I am at the limit of my trouble shooting. Can someone please help. Apparently there are some logs I can attach but not sure if server side or client? Also I am thinking tcpdump might help but I don't know enough about it to use it. Any and all help gratefully accepted! TIA -AL
