For the auto-routing between 3 routers, an easier fix is just to compile twice,
without disabling anything. This was tested with auto-routing and auto-gen
IP/MAC both enabled.

SSH works. You need to start sshd on the server. The command is
/usr/sbin/sshd (you need the full path).
I've created the topology in parts 2 and 3 in GINI and it works fine.
You may need to fiddle around with saving the file and toggling route
computation, but in the end I've made it work. Are you getting all
the "nexthop address not found" errors when compiling? That's what I
got before, but randomly toggling the ip/mac and route generation
fixed it. Maybe something we should fix in the next version...
For traceroute, I believe the issue is with the router. Maybe the
professor can confirm this.
Also, is the password for the filesystem, just4now, documented
anywhere? Should I send an e-mail to everyone in the class?
Otherwise, they can't really use SSH.
