ssh -D 8080 user@really.cool.server

So basically you just go into your browser and select socks v5 proxy at port 8080. You can also do some the other way but you can look that up. You might want to also check your sshd.conf for session timeout options. My Macbook times out after a few minutes of no keyboard entry. Making a ssh key file is nice too then you don't have to use a passwd.
