[Mini-NDN] NLSR Configuration File

Sat Apr 8 17:49:11 PDT 2017

There is no configuration option regarding the PIT in NFD's configuration file.

If you want some information about the PIT you would have to add logging messages to the PIT class in NFD and compile and install it again.

1) Where to add PIT logging in NFD:

https://github.com/named-data/NFD/blob/master/daemon/table/pit.cpp

2) How to add it (from NFD developer guide: https://named-data.net/wp-content/uploads/2016/10/ndn-0021-7-nfd-developer-guide.pdf):

To enable NFD logging in a new module, very few actions are required from the developer:
• include core/logger.hpp header file
• declare logging module using NFD_LOG_INIT() macros
• use NFD_LOG_(statement to log) in the source code
So something like this can be added in pit.cpp:

NFD_LOG_INIT("Pit");

3) How to turn it on in Mini-NDN:

In /usr/local/etc/ndn/nfd.conf (if this is not present, then /usr/local/etc/ndn/nfd.conf.sample) add:

Pit DEBUG

here: https://github.com/named-data/NFD/blob/master/nfd.conf.sample.in#L29

Then check the logs in /tmp/<node-name>/<node-name>.log

Dear all,

I am very grateful for your help.

I have another question.

I intend to emulate a interest flooding attack scenario. I've been looking at the NFD settings (/tmp/<node-name>/node-name.conf) and found no configuration regarding the size of the PIT table. If I can not see this, I kindly ask you to help me.

Best regards.

For some reason this message got discarded by the mailing list. Did you get a Welcome message from Mini-NDN mailing list stating you can post (I don't remember if you have to confirm your subscription)?

To modify NLSR conf file, look at the methods here:
https://github.com/named-data/mini-ndn/blob/master/ndn/nlsr.py#L166

Now if you want to change the LSA refresh time:
<https://github.com/named-data/NLSR/blob/master/nlsr.conf#L22>https://github.com/named-data/NLSR/blob/master/nlsr.conf#L12

You can add this:
general += " lsa-refresh-time 1080\n"
before line 187:
https://github.com/named-data/mini-ndn/blob/master/ndn/nlsr.py#L187
Note that \n is important.

If you want to change parameters in any other sections go that section method and add them in a similar way.
Once you have made the changes you would have to re-install Mini-NDN.
This would make the change in nlsr.conf of all the nodes.

In /tmp/<nodename>, if you make the changes there they would be overwritten by Mini-NDN.

Subject: NLSR Configuration File

Dear all,

I am beginner in using Mini-NDN emulator and have encountered problem in
configuration of NLSR.

I know that Mini-NDN creates for me NFD and NLSR configuration files for each node, and they are located in the /tmp/<node-name> directory. However, I need to modify some NLSR configuration parameters and I'm not sure exactly where I can do this. I tried to edit the configuration file created in the /tmp directory, without success. I tried using the GUI to make modifications like site name or max-faces-per-prefix but none of that worked.

If anyone could help me with my problem I would be immensely grateful.

Best regards,
