What about adding w permission to the user and r permission to group and other?

Hi Prof Wang,

Ok.. it was: -r-------- 1 anilj1 anilj1 1643 Apr 26 12:35 %JAmVmylSjFZutfeCI1dUvGgM+kOffJmUp3kLgktBVQ=.pri

After added READ permissions to all, it is now throwing following errorr.

1431666355.351034 INFO: [RemoteRegistrator] Load remote_register section in rib section
1431666355.351254 INFO: [RemoteRegistrator] Load remote_register section in rib section

1431666355.370436 FATAL: [NFD] Error in setting interest filter (/localhost/nfd/rib): Unauthorized command

Ideally, I am trying to run the 'nfd' in debug mode, either from Eclipse or from command line gdb, to do a step wise execution. I want to understand certain part of the code. Any pointers for this case will help.

What are the permissions of the .ndn directory and the files in it?

Hi,

I am attempting to run 'nfd' from compiled binary. However, I am running into a following problem. (see the last line).

I also tried after changing the grp and owner of the /home/anilj1/.ndn to 'root' but yet it did not help. Is something missing here?

One thing I am not sure when the .ndn folder is created? Is it created first time by the nfd process after it is started? What if I remove this folder before I start nfd locally?

Also is it possible to run nfd from a local user and not with sudo proviledges?
