How to set up NFS between the car and your laptop

This guide explains how to set up NFS between the car and your computer for easy transfer of the video and sensor streams to your laptop.

After setup, one has to mount the exported directory each time to use it.

###Server setup (your laptop)

• Install the NFS server and client

apt-get install nfs-kernel-server nfs-common

• Create the directory you wish to export and give the mounting computer all permissions (maybe not ideal, but if using 755, you have to run proxy as root)

mkdir /home/nfs_carolocup

chown nobody:nogroup /home/nfs_carolocup

chmod 777 /home/nfs_carolocup

• Add the following line (it is ONE LINE) to the list of exported directories at etc/exports. This gives mounting access to your specified folder using both WiFi and Ethernet cable.

/home/nfs_carolocup 192.168.137.0/255.255.255.0(rw,async,no_subtree_check,no_root_squash) 192.168.0.0/255.255.255.0(rw,async,no_subtree_check,no_root_squash)

• After modifying etc/exports, restart the server

/etc/init.d/nfs-kernel-server restart

Tip: See the directories that can be remotely mounted by

exportfs

###Client setup (the car)

• Install the NFS client

apt-get install nfs-common

• Create a directory where the exported directory can be mounted

mkdir /opt/msv/bin/2013/DIT-168/project-template/recs

• Give permissions, so that if the directory is not mounted, one does not need to run proxy as root

chmod 777 /opt/msv/bin/2013/DIT-168/project-template/recs

• Mount the directory, be sure that the directory used for mounting (recs) is empty in the car. X = 137 if cable or 0 if WiFi, Y is your device

mount 192.168.X.Y:/home/nfs_carolocup /opt/msv/bin/2013/DIT-168/project-template/recs

• Unmount by

umount /opt/msv/bin/2013/DIT-168/project-template/recs

Tip: Check your mounted devices by

mount
