How do I tunnel and browse the server webpage on my laptop?

  • 772

I run a web app in one of my lab servers, and I have already setup X11 Forwarding on those machines. Other lab members can tunnel through SSH, and browse that web app on their local browser at home.

I can't. Last time I checked with them, there is almost nothing I need to do.

When I type 192.168.1.113/webapp I get nothing.

Any tips?

THanks.

I ended up using the second method :)

ssh -L 8080:<server-ip-address>:80 <username>@<remote-addr> -N
ssh tunnel remote

    There are two ways you can do this with SSH.

    Tunnel Everything with a SOCKS proxy

    Log in to the remote machine using the following command:

    ssh -D 8080 remote-host

    Now go to your browser's proxy settings, and configure it to use a SOCKS proxy with host name 127.0.0.1 and port 8080 (or whatever port you passed to the -D option). Now all pages you load in your web browser will be tunnelled through the SSH connection. You should now be able to access the private web page in the same way you would from the remote host.

    Once you are done, set your browser's proxy settings back to normal.

    One down side of this method is that all other traffic in the web browser will also be going through the SSH connection. On the upside, you can access the remote servers with their real host names, and can easily access multiple private sites.

    Tunnel a single port.

    The alternative method is to use SSH to forward a single port:

    ssh -L 8080:server-hostname:80 remote-host

    Now if you point your web browser at http://localhost:8080/, you should see the contents of http://server-hostname/ as it would appear from the remote host.

    The benefit of this method is that it leaves the rest of the browser traffic alone. The downside is that some links might not work if the remote site uses absolute URL references. If the site mostly uses relative URL references, then this method should be sufficient.

    For both of these solutions, there is nothing special about the port 8080. You can use any free local port number you want, as long as you remember to use the same one in the ssh invocation and in the web browser.
