NFS shell that provides user level access to an NFS server, over UDP or TCP, supports source routing and "secure" (privileged port) mounts. It's a useful tool to manually check (or show) security problems after a security scanner has detected them.
Originally released by Leendert van Doorn, updated to support NFSv3 by Michael Brown
This takes a bit of work to compile in modern systems
You can search for the existing header files on your system
locate readline.h
locate rpc.h
if you have them, you can simply update the Makefile
Otherwise, ask apt
sudo apt-get update
sudo apt-get install apt-file -y
sudo apt-file update
apt-file search readline/readline.h
apt-file search readline/readline.h
apt-file search rpc/rpc.h
sudo apt-get install libtirpc-dev
sudo apt-get install libreadline-dev
After fixing the Makefile
make clean
make
./nfsshell
