 ====== ssh over proxy ======
+=== With Putty on Windows (Linux Destination) ===
+To connect behind a proxy/firewall etc, from Windows (Source) to a Linux Host (Destination):
+First install Openssh on the linux destination computer, and run it on port 443.
+Then get the [[http://proxytunnel.sourceforge.net/|Proxytunnel]] Windows binary and run the following command in cmd:
+(switch PROXY_HOST_OR_IP:PROXY_PORT with your proxy's hostname or ip and port, and DESTINATION with destination ip.)
+----
+''proxytunnel.exe -a 1337 -p PROXY_HOST_OR_IP:PROXY_PORT -d DESTINATION:443''
+Then simply run putty and connect to localhost on port 1337. You should get a login prompt.
+If for whatever reason it fails, you may have a more restrictive proxy that requires SSL traffic on that port.
+To get around that, simple use [[http://www.stunnel.org/|stunnel]] to wrap ssh's TCP connection with SSL:
+On the Linux box (as root):
+----
+''stunnel -f -D 7 -d 443 -r 127.0.0.1:22 -p server.pem -N sshd -O 1:TCP_NODELAY=1 -O r:TCP_NODELAY=1''
+and then on the Windows Box, get stunnel binary and edit the stunnel.conf file:
+----
+''
+client = yes
+[ssh]
+accept  = 995
+connect = 127.0.0.1:1337''
+Then start stunnel and connect using putty to localhost on port 995.
+What should happen is that stunnel, will connect to proxytunnel on localhost:1337
+which will connect to the proxy which will connect to the destination, and get you a shell. At least, it worked for me 8-)
