For this project we had to put OpenBSD on desktops in the classroom. First we went and got the installer file from the openBSD website and loaded it onto a floppy disk. Then we set up all 8 desktops under the desk and hooked them up through a switch so that we could use 1 monitor and 1 keyboard for them all. Then we had to change some HDDs because a few were bad. Then we had to change a battery on one of the motherboards that runs the bios and then we had to add some RAM to a few desktops as well. When all was done we put the floppy in each computer and loaded the openBSD BIOS into the computer. We named all the computers versions of derp, setup IP addresses for each and allowed each of us to ssh into the computer when on the network. we had to make each of the computers numbers off by 1 for the ip addresses.
Web Ring Adventure
In class we decided to do a small project, similar to the web adventure project we did in UNUIX/LINUX. First, we made a basic html and an image made into a URL which pointed to the ip address of the next person. One would point to another and another and so on until the last person pointed back to the original. We used “a href” with a url to an image from the web and then the ip address embedded within that “a href” to the next person.
Class Time Script
We have been working on a script in class to be able to grab a users time logged into Lab46 and sort it. We are sorting it between time in class and time outside of class. We want to see how much time a user spends outside of class rather than in class. We also are sorting by the time that class starts and the time that class finishes so that it is not calculated into the time spent online and we can get a more accurate reading. (Lots of math.. lots..of..math).
Grub and Debian We installed Debian over top of OpenBSD today. After doing so we then set partitions for Debian, and OpenBSD to be installed on the same machine. Still having issues with getting Grub to recognize both OS and getting to choose one.
