Avoiding SSH timeouts

I use SSH a lot, and it is a pain when my session times out. This often happens when I step away from the task at hand for a couple minutes. Most of the time, this task is editing a file in vim, and I end up having to restore the file, delete the swap file, etc. Not fun.

My solution for a while was to use screen. This way, I reconnect and continue where I stopped. Better, but the timeouts are still annoying as my terminal becomes unresponsive and I have to close it and reconnect on a new one.

So I decided it was time to solve this. Turns out a simple Google Search found the solution on this blog, and it is dead simple:

Edit your ~/.ssh/config file and add a line containing ServerAliveInterval 60. This sends a keep-alive packet every 60 seconds, which is more than enough to keep your connection from timing out.

Painless, right? Now go and configure your machine, too!


More comfortable reading on the computer screen

Reading PDFs and long texts on the screen has always been something that bothered me and most people I know. It’s just not comfortable! Well, today a colleague of mine showed me something that feels like a solution so good that I wonder why it took me so long to actually stumble upon it.

Multiple terminals in a single SSH session

When I sit to work, I am using linux terminals 95% of the time. And I tend to use lots of them. One for vim, another for compiling and testing, another for checking whatever files the program outputs, and so on… If you’re a multiple windows/tabs kind of guy (or gal, why not?) like me, you know what I am talking about!

Ctrl + Shift + N is my favorite shortcut ever on gnome-terminal, but when I am not physically on the machine but working via SSH, it is not nearly as fun. In fact, it is annoying as hell as it opens a new local terminal, and I have to log in again, go to the path I am interested in, and only then being able to do whatever I want to do (which, sometimes, is pretty quick and I end up closing the terminal, just to regret next time I need it again). Thankfully, I found a nice way to solve this!
