![]() Prox圜ommand /usr/bin/corkscrew 3128 %h %p Define an alias like this in your ~/.ssh/config, where is the proxy you use for HTTPS to outside (replace by the proper host name and port): Host myserver If you need to set a web proxy in your web browser, tell ssh to go through the proxy. ![]() If that works, define an alias in your ~/.ssh/config: Host myserver If you don't need to set a web proxy in your web browser, then you can try connecting directly: ssh -p 443 ![]() If it is, you'll need to find another port that the firewall lets you use or to find another ssh server (see forwarding below). Note that this assumes that the ssh server is not also an HTTPS server. In addition to the Port 22 that should already be there. You can configure the port in /etc/ssh/sshd_config: add a line Port 443 If you have control over the server, make it listen on port 443 in addition to 22 (the normal ssh port). (It is possible to distinguish HTTPS and SSH, so this won't work if the firewall is sophisticated enough.) But port 443, which is normally the HTTPS port, often works, because SSH and HTTPS look a lot like each other to filtering software, so your SSH session will look like an HTTPS session. Port 80 is unlikely to work, because most places that have firewalls analyse the traffic on that port and block anything that isn't HTTP. If the firewall lets you, you can run ssh to any port, but that requires the ssh server to be listening on that port. In short, it might just be safer to talk to them. If they've got a reason for blocking ssh, it's likely they'll view any extreme attempts to circumvent it fairly negatively. You need to do something and they're stopping you. ![]() You might just want to have a word with your network admins. This should skirt around the firewall problem completely because it all happens on Port 80 but it will require you to be running Apache and set up a number of things:Ī VPN might be an option but if ssh is locked out, I'd expect that to be excluded too. Your bzr path would then look something like: bzr+ssh://host:80/path/Īnother method is to use WebDav. You'll need to edit /etc/ssh/sshd_config and change Port to 80. Warning If you have something else running on port 80 (on the server) this will not work and will likely mean you completely lose SSH access to the server! If you have control over the server, and still want to try it, you can change the sshd port to port 80. If anything is not clear, just leave a comment.A good corporate firewall will inspect traffic regardless of port so changing port just might not work. Now all we need to do to visit the website on Server B would be to enter the following URL in your browser: Were you to use (for example) port 80 it might produce unwanted results such as your local apache (if you have one) being unreachable. See that we used port 8081 as local port? We did that to prevent collisions with services on our local machine. Ssh tunnel 80 full#To complete this exercise I will show you the full command with which we could satisfy the requirement in our opening example: You might notice the use of a double -t argument in our command this is not an error but is actually required in order to create the connection (without it your system might complain that it is unable to acquire a TTY explaining the details of this would go beyond this blog posting)
