Before I get into the detail of my weekend there are two things that I need to be sure to write about. They both have to deal with two small problems I had when using my linux box a couple times. One has to do with eth0 not starting up on boot and the other was a problem with the cdrom drive refusing to open.

Eth0 not starting on boot

Well for a few weeks now I have been having this problem, It probably happened the last time my cable internet went down and didnt come back up. I went in and changed something on my network settings to get my network connection back up but never changed it back. Not really sure what it was, and I really didn't notice the problem till I tried to run Nmap recently. It kept telling me that I had to specify my source address because it could not find it. I found it interesting since I have DHCP running and I should have had one.
After the ifconfig indeed showed me that there was no IP specified for eth0 I had to try to resolve that. Since I use redhat I went into "neat" and saw that my network device was eth0:1 instead of eth0. To get my network connection working on startup again I copied the ifcfg-eth0:1 into ifcfg-eth0. When I did this it showed eth0 as a selection for one of the network devices. I deactivated eth0:1 and activated eth0, did a restart, and it came up on boot this time. I also did an ifconfig and saw that I also had an IP address. I think this also caused me some network congestion problems, but that had to do with my gateways. On to the next problem...

Cdrom drive will not open

This was a very interesting problem since at the time I thought I had no programs running and I wasn't currently doing anything to the drive. Every time I tried to unmount the drive though it gave me the "device is busy" error. So I had to figure out what in the world was going on, so I did a google search for possible solutions to my problem. I found that in LSOF, I did /usr/sbin/lsof /mnt/cdrom and it showed me a process that still had a hold of the cdrom drive. After I killed the process I was able to unmount the drive finally.
