Aqui estão os passos que tomei até agora:
server01 # apt-get install nfs-kernel-server
server01 # mkdir /home/acoder/Public
server01 # vi /etc/fstab
Encontrei algumas informações úteis quando "grepped":

Aqui está a saída de showmount -e 1.2.3.4 no cliente:
Export list for 1.2.3.4:
/export/public 192.168.1.0/24
/export 192.168.1.0/24
Acho que também tenho acesso negado ao tentar montar o compartilhamento nfs no próprio servidor:
\# mount -t nfs -o proto=tcp,port=2049 localhost:/export/public/ /mnt/server01public/
mount.nfs: access denied by server while mounting localhost:/export/public/

Export list for server01:
/export/public 192.168.1.0/24
/export 192.168.1.0/24
Agora para o cliente:
client01 # mkdir /mnt/server01public
client01 # mount -t nfs -o proto=tcp,port=2049 1.2.3.4:/public/ /mnt/server01public/
mount.nfs: access denied by server while mounting 1.2.3.4:/public/
Eu desliguei o firewall do servidor (ele está na minha rede doméstica local) e ainda recebo o mesmo erro.
0 O que estou perdendo?

Resolvido.
Editou / etc / exports e adicionou o IP específico da máquina cliente:
# added the following lines
/export 1.2.3.0/24(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)
/export/public 1.2.3.0/24(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
Emitido exportfs -a e conseguiu montar a partir do cliente.
