Protocol error in vagrant synced_folder

If you have “protocol error” when writing something in vagrant synced folder from inside vagrant guest vm change the permission of the synced folder in the host os to be readable by the guest. Naive (not recommended for security) to set 777 permission the synced directory.

For synced folder, I have following line in Vagrantfile

 config.vm.synced_folder  “/vagrant/precise32”, “/download”

 

Now run the following command to get rid of protocol error:

chmod 777/vagrant/precise32
