A ssh tunnel for Firefox to a remote computer is good security measure. Especially when connecting via an untrusted network like a wifi hotspot or other public networks. The tunnel encrypts and sends the data to your remote machine then it is sent over the web to your destination. This tutorial assumes you have an account on a remote machine you can ssh into. This is a pretty easy set up.

Now all you need to do is login your remote computer that you have access to with SSH then issue this 1 command

ssh -D 9999 -C me@ipaddress.com

The -D switch - Specifies a local “dynamic” application-level port forwarding. We are also adding the -C switch for compression.

Next we need to put the settings into Firefox.

Firefox> Edit> Preferences> Advanced tab> Network tab> Settings button.

Select Manual proxy configuration

SOCKS Host: localhost Port: 9999

SOCKS v5

No Proxy for: localhost, 127.0.0.1

Note: Sometimes localhost can cause a problem. If your settings are right and it still is not working replace localhost with 127.0.0.1.

When you try to login using ssh some users might find asking for ssh password is slow here is the solution how to fix this problem.

Solution 1

Edit the /etc/ssh/ssh_config file using the following command

sudo vi /etc/ssh/ssh_config

Commentout the following lines

GSSAPIAuthentication yes
GSSAPIDelegateCredentials no

save the file and exit

Solution 2

If you got to System>Administration>Network

Now you should see similar to following screen here click the "General" tab

You need to Uncheck the option that says "Scan for available services and advertise . . ." and close

Now you can try to login using ssh you should see it will prompt for password immediately
