surresh...
Sorry I haven't had time yet. my wife is the head of a non-profit that
helps poor children learn to read and they have a major fund raiser
tomorrow nite.
As usual I was asked to donate my time to put together the powerpoint
slides, the projector etc <g>
I'll try sometime next week.
I did though send info about KaanalNet to a researcher at UC Berkley and to
a friend of mine at Canonical that is working on SDN.
They both seemed interested and planned on taking a look also. The wiki
will help alot of people get started as it fills in with info over time.

Hi Brian,
Did you have chance to test with some topology?
Thanks

FYI... I'm trying to get some visibility for your project on the LXC
sub-reddit:
https://www.reddit.com/r/LXC/comments/3l77xg/kaanalnet_network_emulator_for_traditional_sdn/
The LXC sub-reddit is fairly new so not alot of traffic/awareness yet but
it will grow in numbers.

Hi Brian,
I acknowledge the issue. The issue was "tcpdump" optional package
installation failed in the lxc template, that was the reason.
I just fixed and updated the kaanalnet package(version - 0.1.0).
Now installation works without error. I just tried, and attached the logs
for your reference.
you need to install the kaanalnet again.

Hi Brian,
1. Are you running the installation as Root User?
2. Also can you paste the output of "lxc-ls --fancy" command.
Thanks

Ok... I've tried this now on 3 machines. All are ubuntu 14.04 servers
and I followed the instructions
I used the instructions found here:

On all three the install errors out (see partial text below)

Hi Brian,
I dont have immediate plan. But definitely i will bring in, once all the
planned features are completed,
Also i do have plan to bring Docker as well.
Please raise the questions, i am happy to answer.
Thanks

Are there any plans to take advantage of LXD
<https://github.com/lxc/lxd/blob/master/specs/rest-api.md> in KaanalNet
in the future also?
Unprivileged & Privilieged LXC container use ?
Sorry for all the questions.

Hi Brian,
Yes. I agree with you. Thats the main reason to develop this.
KaanalNet also supports the traditional networking topology with self
configured router(Quagga stack runs).
I am started revamping the Wiki Page with more SDN use cases ,
traditional network topology use cases, mixed networks etc.
Please keep a eye on this.
https://github.com/sureshkvl/kaanalnet/wiki
kaanalnet.org
The only limitation is ,
KaanalNet supports only UBUNTU 14.04 + OS.. (Note: I havent tested on
other Linux variants, it may or may not work).
thanks

That will be awesome thanks.
Besides myself I'd seen a lot of people request full LXC containers in
mininet over the past couple years. Not being
a programmer there wasn't much I could do until someone who is a coder
added the full LXC capability though.
It would have been great for that to happen and then be able to utilize
that with Maxinet <https://github.com/MaxiNet/MaxiNet>, ODL etc
I'll get KaanalNet installed and start playing with it to see what all is
different from mininet.

Hi Brian,
Mininet uses the network namespaces. KaanalNet uses the LXC.
Yes, kaanalNet utilizes the lxc-create,start,stop,clone etc to create a
nodes.
When you create a topology, the node is created a UBUNTU LXC container,
which can be accessible via SSH.
Yes. you can install any application as you want.
Thanks

On the KaanalNet wiki page it says:
*KaanalNet uses the Linux Containers (LXC), openvswitch, linux bridge and
ping,iperf(traffic utilities). KaanalNet is tested with OpenDayLight and
POX SDN controller.*
I'm just trying to clarify what "*uses the Linux Containers (LXC)*"
means. Mininet uses the LXC terminology also but does NOT use the
linuxcontainers.org
API for LXC <https://linuxcontainers.org/lxc/introduction/>.
Mininet uses only a "lightweight" linux container and not an LXC container
where you have a full OS running in the LXC container & sharing the kernel
of the host machine.
It would be great if KaanalNet really used the lxc-create, lxc-start,
lxc-stop, lxc-clone etc command set/API so it would be possible to install
an actual application into the KaanalNet network host/nodes.
Thanks for any clarification.
Brian
