+Making life easy over flaky links
+=================================
+
+I tend to work over VPN, which we know can be flaky at times, Since I
+work on server, I spend a lot of time ssh'ed into hosts. I was getting
+tired of the lost time having to restart what I was working on every
+time the VPN dropped (which could be as much as every 15 minutes on a
+bad day). While I already used screen to handle the lack of terminals
+(Alas, I am forced to use a Windows laptop to VPN in with), I thought
+there could be an easier way to do this.
+
+The way I tend to work is that I ssh into a jump server, fire up screen,
+then ssh into the hosts I need to work on, and fire up screen on those
+hosts.
+
+Now, this is nice, but it can get a bit tiring to do it all over again.
+So, I found a tool called [autossh](https://www.harding.motd.ca/autossh/)
+which will automatically restart your ssh session if it drops for any
+reason but a graceful disconnect. (Well, there are others, but this is
+basically it). Combine this with your ssh-agent, and you can re-attach
+with easy. I also use [keychain](https://www.funtoo.org/Keychain) to help
+manage my ssh-agent when I log in.
+
+Now that the connection will come back, I need a way to re-attach to my
+screen session, or if there is not one, to start one for me. To do\
+that, I have this is my .bashrc file:
+
+    test -x $STY && screen -xR
+
+This will check to make sure that we are not already inside a screen
+session on the local host (*test -x \$STY*), and if we are not, then
+either attach to an existing screen session or start a new one (*screen
+-xR*)
+
+I have define this function in my .bashrc to spawn a new ssh connection
+in a separate screen window:
+
+    function ss ()
+    {
+      screen -t $1 ssh $*
+    }
+
+Easy stuff
