It seemed like it was going to be a short simple set of tasks this evening. All I was going to do was reconfigure the Ethernet card on the server. I wanted to change it from DHCP to Static and then add the new IP address to the hosts files on the clients on the network.
First, I had to do a little research on where to update the IP address. OK, simple enough. All I have to do is modify the interfaces configuration file located at /etc/network. I also found that the hosts file was located at /etc on the server so I might as well modify it as well.
Second, I had to open the interfaces file. Hmmm. In command line Linux I don't know the best editor to use. Thinking back I seem to remember using vi or emacs. I first tried vi. No luck. In fact, all I could do was destroy the file. I don't seem to remember the commands. So next I try emacs. Once again the commands are beyond me.
Obviously, tomorrow I will have to brush up on the editors in Ubuntu so that I can modify these files. I will also have to update the network map in add the new server once I set the IP address to a static address.
