[TAG] Question on how to block a ssh host from being used as a Socks proxy

[Suramya Tomar]

Hey Everyone,
  I have been using a SOCKs proxy via SSH (using port tunneling [1]) to 
browse the net from unsecure locations and it works great.

  However I have noticed that when I connect to certain hosts I am 
unable to use the connection as a SOCKS proxy and I was wondering how 
these hosts were configured to do this. It seems like a good feature to 
have on servers that I configure. Are there any disadvantages to this 
setup that I am missing?

  I have tried looking for a solution online but I guess I am not asking 
the right questions because I didn't find anything useful. So any 
idea's/suggestions on what/where to look?

Thanks in advance.

[1] To set up a SOCKS proxy using SSH from a windows system follow these 
steps:

Open PuTTY. You should be greeted with a configuration screen. First, 
you will enter the hostname or IP address of the SSH server. Type in a 
name for your connection settings in the box below ?Saved Sessions?, and 
click the Save button.

Now you need to look at the tree of options to the left; expand the SSH 
tree, and select ?Tunnels?. Enter 4567 (or any port number above 1024) 
in the Source Port area, and click the Dynamic radio button to select 
it. Leave the Destination field blank, and click ?Add?.

Now go back to the Session tree (very top of the left section), and save 
again. You will be prompted to enter a username, which is the username 
of your shell account. Type that in, hit enter, and then type in your 
password when it prompts you.

In your browser change the proxy setting to localhost and the port you 
used earlier and you can browse the net safely.
