Hello all!
I'm relatively new to FreeBSD but I'm enjoying it so far.
I have FreeBSD 9.0 installed as a VirtualBox guest, and I plan on
cloning it repeatedly to set up a fake network for me to toy with (e.g.
setting up clusters of replicated databases, web server pools, etc).
Here's the list of things I need to change on each new clone, am I
missing anything obvious? Or are there any gotchas to what I'm trying?
1) I have to change the hostname in rc.conf
2) I have to change the IP address in rc.conf (I'm using static IPs)
2a) I saw (on the internet) some people having problems because
VirtualBox generates a new MAC address for cloned "machines", which
somehow screws up the naming of the network interfaces (e.g. they get
renumbered, thereby ignoring any configuration you have set up). Now I
can't find it anymore, at least not for FreeBSD. Some Linux forums have
info about "/etc/udev/rules.d/70-persistent-net.rules" which doesn't
exist in FreeBSD as far as I can tell. Is this a concern? I don't seem
to be having a problem but TBH I'd rather understand what is going on
than just be lucky.
3) Create new SSH keys
3a) For host keys, I can delete the existing ones in /etc/ssh/ and
reboot, is there a better way?
3b) Should I bother changing the SSH keys for any users I have? It
is basically one user (I use to log in with) which will be the same
across the board anyway.
Thanks for any insight!
