[Mini-NDN] Where does mini start the nfd?

[Ashlesh Gawande (agawande)]

I am not sure how you would run two instances without Mini-NDN.


client.conf tells programs (NLSR etc.) how to connect to NFD i.e. which sock file/transport to use.


I think you can export different $HOME in two different terminals and then put two different client files in there and then run NFD.

Thanks! An important question.

I would like to avoid mini and run two nfd different istances in two
different process.
I noticed that it is not possible use nfd-start, then I do the following:

Process 1:
nfd --config nfd.conf

Process 2:
nfd --config nfd2.conf

Where "diff nfd.conf nfd2.conf" is:
90c90
<     path /var/run/nfd.sock ; Unix stream listener path
---
>     path /var/run/nfd2.sock ; Unix stream listener path
97c97
<     port 6363 ; TCP listener port number
---
>     port 6364 ; TCP listener port number
106c106
<     port 6363 ; UDP unicast port number
---
>     port 6364 ; UDP unicast port number
179c179
<     port 9696 ; WebSocket listener port number
---
>     port 9697 ; WebSocket listener port number


I noticed that it is not enough. I had a look on the code that you
passed me in the previous answer. I notice that client.conf file has a
role. How can I reach my goal?
Thanks a lot.
