Two Linux notes
SSH Tunnel for web traffic
ssh -D 9998 -C firstname.lastname@example.org
Where "myserver.com" is a server you operate with SSH setup. Now you need to configure your browser to use the tunnel. In OS X you can go to Network -> Advanced -> Proxies -> Check SOCKS and input
localhost:9998 or whatever port you used. Directly from Chrome you can also select Preferences -> Under The Hood -> Change Proxy Settings... -> and it will go directly to your OS X Network/Proxies tab.
Compare your IP address at any of the check IP sites, I like canihazip.com. It should be the IP of your SSH server and not your coffee shop/hotel/wherever you are connected.
Visualize your running processes
I just learned this command today, it gives you a visual tree like look at your processes running. I don't have very many processes running on my VPS so this is a quick way I can check which SSHD process I just ran this command from so I can kill a different SSHD process. Probably not the most efficient way to do that but it works! :)
