Question of the libnfs-python

[wang larry]

Greetings, 

I am pretty new to the libnfs, and investigating on if it is possible to use this tool for the NFS server stress testing, I have limited NFS clients(say, less than 5) but I want to simulate around 1000 nfs clients, is it possible to do it by using libnfs-python?

BR, 
Larry

Also, just found the tool dbench could do the same, however, I tried the steps following the steps here but did not work, below is my testing steps:

1, start the tshark: tshark -i eth0 -s 0 -w nfs.cap host 10.53.175.197

2, [root@VM_248_193_centos ~]# tshark -v
TShark 1.10.14 (Git Rev Unknown from unknown)
