I had something unusual happen and thought I should mention it, see if it was worth reporting to someone.
I was going to arping something the other day and found it wasn't installed. So I used sudo apt-get install arping. It went through fine, I was arpinging happily. I shut down for the night, and then this morning, I couldn't connect to the internet.
I do some searching around and get eth0 added to me /etc/network/interfaces correctly, and I'm back online, but I can't see the network manager to connect to a wireless network; not a big deal since I have a dock here, but I might want to go on the move.
So, I start looking around forums and in the process of following some of those guides, I find NetworkManager is not installed!
I get it installed and everything managed properly again. My system is working as intended. But now I'm curious what happened, so I start looking at some of the logs in /var/log. Then I find this in /var/log/apt
peatheri@philip:/var/log/apt$ cat history.log | grep network-manager -B 4

Why is installing arping removing network-manager? Is this a bug in the package, the repository, sunspots?? I was concerned so I figured I'd post it, and maybe if someone else has this issue, they'll see an answer.
