Hi Ishita,<br>
<br>
Sorry for the late reply! I was on vacation last week.<br>
<br>
3. I started the ndnfs on server: ./build/ndnfs -d /users/idasgupt/dataset<br>
> /tmp/ndnfs4.<br>
<br>
In ndnfs-port argument list, the second directory is the mount path, and<br>
the first is the actual path.<br>
So in order for your file to be processed by ndnfs-port (fuse hooks<br>
executed), please put it in "/tmp/ndnfs4" instead of<br>
/users/idasgupt/dataset.<br>
<br>
Please let me know if this helps!<br>
<br>
Thanks,<br>
Zhehao<br>
