i am trying to set up a ssh connection on one of my computers and am trying it over the lan so i can make sure it works, but it doesn't
i'm setting it up for windows as shown  here , http://www.buzzsurf.com/surfatwork/#config_ssh
i get an error saying "the server unexpectly closed the netwok connection"
(the firewall is closed on the server computer)
does anyone happen to know y?

I read the tutorial you are following and it sounds more or less correct (it's a lot of info to swear for every little bit of it, but I am familiar with SSH and tunneling and nothing I read there raised any red flags). 

If you are testing this on your LAN behind a router, and are trying to connect to your public IP address (such as shown by whatismyip.com), this may fail due to a limitation of many routers -- even though it would work just fine if you were connecting from outside.  Try to connect to the internal IP address of the computer hosting the sshd server instead, or ask someone else to test it for you.

yeah i have to computers on the network, 192.168.1.2 running sshd on (edit i changed the port to  443 as the tutorial and it still doesn't work)
port 443 i have putty running on 192.168.1.3 connecting to port 443 and i get connection refused
help plz
