it just works

I was just called by a customer that I was supporting some time ago. They were desperate because the on-premises document server was not responding from Internet.

I figured out that it was because they have a new public IP, so I SSHed to the server to check the dynamic dns script. As I wanted to use vim instead of vi, I tried to install it with “yum”, but it was not installed… “apt-get” the same….
Finally, I realized that it was a RED HAT 5.3 !! it was working there for years! without maintenance
