Solved NFS Mount Port Mapper Failure

[ThePieMonster]

I am trying to mount a NFS share that is on my CentOS machine but I am receiving the following error.

This is from the BSD machine

mount 10.19.2.12:/var/nfs /mnt/centnfs/
[tcp] 10.19.2.12:/var/nfs: RPCPROG_NFS: RPC: Port mapper failure - RPC: Timed out

Timeouts usually indicate a firewall, CentOS 6 and higher has it enabled by default. Note that the exports file on FreeBSD uses a different syntax. The one you have isn't going to work. It's also not necessary for NFS clients, it's only used with the NFS server.

Yes on the CentOS machine I had to run
systemctl stop firewalld
systemctl disable firewalld

Also the /etc/exports file on the BSD machine became
/var/nfs -maproot=root 10.19.2.12 10.19.1.12

I was able to successfully mount via the below command
mount -t nfs 10.19.2.12:/var/nfs /mnt/centnfs/

Thanks for the assistance.
