How do you guys document your networking environment?
I am the sole admin of a small system, and it just seems bad practice
for the sole repository of all that info to be my head. For one, my
head is notoriously unreliable for that sort of thing. Also, it can't
be backed up.
Right now I have a small setup with a firewall, an ltsp server, five
clients, a wireless connection, and a stand-alone workstation. More to
come later (printers, more services, etc).
I'm planning to fire up an svn server to use as a repo for all the /etc
directories on all the machines. I also have a text file with
descriptions of every technical detail I could think to put in it:
equipment specs, models, location, function, wireless encryption keys,
power feeds (i.e., ups or not), ip addresses, services, etc.
I intend to draw a network map tonight, and I'm going to print that and
the text file out and keep them in the network closet, maybe hanging on
the wall. I'm also thinking that I will write the root passwords down
on a piece of paper, seal it in an envelope, and put it in the network
closet. That might seem like a bad idea, but if they can get in the
network closet, they can already pwn the system. A sealed envelope
would provide for an easy way to get the info should something happen to
me, and would provide a pretty decent indication that the info had been
accessed. Kind of an "In case of emergency, break glass" approach.
Is there a better way to store all this info? Maybe some software
(FLOSS only please) has been written to deal with this already? What do
you guys do?
