Hi Brian,
Great. Its ready to use.KaanalNet works based on REST API.You can use any REST
API client. (personally i prefer Google CHROME POSTMAN )
Please read in the below order,
1)
The workflow is explained here with simple example.
https://github.com/sureshkvl/kaanalnet/wiki/Workflow2)
REST API Details are available in the below link, (it gives overview of all the
available REST APIs with
example)https://github.com/sureshkvl/kaanalnet/wiki/RestAPI
3)SDN Topology examples are available in the below
link,https://github.com/sureshkvl/kaanalnet/wiki/Sdnexample
4)Traditional network examples are available in the below
linkhttps://github.com/sureshkvl/kaanalnet/wiki/Traditionalexample
5) To design your own topology,you need to understand the "Topology
Schema".https://github.com/sureshkvl/kaanalnet/wiki/Schema
Thanks
Suresh.

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.https://github.com/sureshkvl/kaanalnet/wiki/Troubleshooting
Thankssuresh.

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

clues what I might look at to get this to install okay?thanksBrian
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.
Thankssuresh

Are there any plans to take advantage of LXD 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, 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.
Thankssuresh.

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.
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
