To support inand control (on vigil2) you probably have to bring up of0
and give it an IP address.
e.g.
ifconfig of0 10.0.0.5
let us know if that doesn't work.

I have tried this:
nox
|
end1 --- vigil1 --- vigil2 --- end2
I ran "secchan nl:0 tcp:10.0.2.2:975" on vigil1, ran "secchan nl:0" on
vigil2. At the beginning neither end1 nor end2 could ping each other.
After 45 seconds, I got the error message on vigil2:
fail_open|WARN|Could not connect to controller for 45 seconds, failing
open. But right from then on, end1 and end2 could ping each other.
Is this the right behavior? If not, what are the things I have done
wrong?
Thanks again for your help,

Following on this thread, in this 2 switches 2 hosts setup, are
there two separate connections from both vigil1 and vigil2 to the
host machine (by s1_SLIRP and s2_SLIRP)? Also, does this mean that we
need to use secchan to connect to the nox_core on the host machine,
from both vigil1 and vigil2?
Then, what if I only setup one secure channel between vigil1 and the
host nox using secchan? Will vigil1 and vigil2 form a spanning tree,
and vigil1 will forward control messages for vigil2? I am a little
confused here.
Thank you so much,

The number of VMs and their connectivity are specified in the
vms.conf file. As an example, here is a file with four VMs total,
two acting as switches (vigil1 & vigil2) and two acting as regular
machines (end1 and end2), one connected to each switch. To add more
VMs, just add new names to the VMS line. The "SWITCHES" provide the
connectivity for the VMs connected to them using the *_NETS lines as
a regular (non-openflow) switch would.

Hi All,
I did the virtual test environment setup using NOX with 1
controller, 1 switch and 2 virtual QEMU machines as suggested in
the wiki.
I want to build upwards from this configuration and have more nodes
and switches under the purview of the NOX controller.
Could you please suggest what would be the best way to emulate more
complicated (close to real life networks) using the NOX controller.
Thanks a lot!
Regards,
Surabhi
