[Ndn-interest] [Mini-NDN] Mininet: connection refused

[Ashlesh Gawande (agawande)]

The mn --nat option attaches the nat to s1 (See: s1 ifconfig)


If you try s1 ping google.com that should work.


If you want h1 to reach google, I think this will help:

Can also study the nat example:

https://github.com/mininet/mininet/blob/master/examples/natnet.py


For routes to reach non-neighbors I don't remember how to set it up but you can try to use "route" or "ip route" command to add static routes to non neighbors.

Can also look into switches: https://github.com/mininet/openflow-tutorial/wiki/Router-Exercise

(Mini-NDN conf parser does handle switches if you want to insert them, but I have not tested it).

You will have to experiment with this as I don't know the exact steps for the setup. I will try to find them.


Can you describe the topology, where do you want to put the Http server?

Dears,
thank you for the interest. I have still some questions unsolved.

1- The sentence:
> You will have to experiment how to integrate NAT with Mini-NDN.
Does it mean that this feature is not available now? I have no idea
how to integrate miniNDN with nat. In mininet I see --nat option, but
here it does not work.

2- However, also writing mn --nat , the command h1 ping google.fr fails.

3- The sentence:
> If you run some form of IP routing (eg RIP or OSPF) then you can
> ping non-neighbors.
Can you explain me how can I perform it?

4- (Final): My purpose is putting a little http server in the ndn
network. To do it,I am confused about what can I do.

Thank you,
Matteo
