I spent a little bit of time trying to find an answer to this today but I was unsuccessful. I’m hoping one of you will have the secret for me. Situation: I’ve configured my .ssh/config file with profile and port information for the many servers I connect to on a regular basis. Problem: One of… Read More »
At work we maintain over a hundred machines, most of which are regularly accessed via SSH by our developers. Due to the number of machines and the number of tasks that need completed, we found that many of the developers would often forget they were logged into a server and leave an idle SSH session… Read More »
I have been tunneling all of my web traffic over an encrypted SSH connection for some time now. Considering the fact that I travel a lot, I’m very regularly on untrusted, insecure networks. I prefer to secure those connections (web, IM, email, etc) by creating an encrypted SSH connection and pushing the traffic through it.… Read More »

As far as I understand these are interchangable in their features, its just another more flexible way for you to connect to a remote… Read More »
You might remember a recent tutorial I did on securing VNC via SSH with the -via option of vncviewer. Today I started looking into it more with one of my students and we wanted to make the -via option use compression. By default it just creates a basic tunnel with SSH and doesn’t let you… Read More »
I was discussing VNC this afternoon with some students and the question came up on how to secure VNC. As you may have noticed most network protocols do not have much for built in security. Many rely on other programs for their network security needs, such as ssh. This is also the case with VNC.… Read More »
