Re: ITT: Biggest blunders of 2012 (so far!!).
Must have been something between eating minestrone despite my legume allergy (two hours in the hospital for me yesterday) and typing "ipconfig et0 down" in the third overtime hour of a total of six extra hours in the lab. I really thought I was inside Vim, when I actually hammered that in Bash. I spent 20mins climbing around in the server room hooking up a nullmodem cable to that computer and the next server I could find and 2 hours and 40 minutes fixing the old DOS database I broke in the process. The women in the lab don't know I broke it, I'm now some sort of a hero. You know? Like a fireman burning down a house to keep his job. Don't code when you're tired.
One good result: All the servers in the server room are now connected via RS232 to a single... let's say terminal server in the closest sense of the word. I used four PCI cards with 4 USB slots each and for each USB port a single adapter with two serial connectors. I managed to connect all the Linux servers with that terminal server, which can be reached via SSH, XDMCP, NX and VNC, so all the severs can be recovered by already open minicom sessions (wrapped in a big tmux sessions) if something like that ever happens again. It might be overkill, but I felt like it was the most sane thing to do.
