** On the Server ** This documents takes you through setting nfs shares on a fedora family OS. The core packages that need to be present are =autofs, nfs-utils=

sudo dnf install autofs nfs-utils

Create the directories to share. In this case two folders under the share directory

mkdir -p /shares/share{1,2}

To tell nfs-server, what folders to share we edit the ==/etc/exports== with the following lines:

/shares     *(rw,no_root_squash)

For more examples on how to edit ==/etc/exports== consult the man page at man exports and navigate to the bottom of the page.

systemctl start nfs-server
systemctl enable nfs-server

Allow external programs access by changing the firewall(nftables). Rpcbind, mountd, nfs are related services that need access.

for i in rpc-bind mountd nfs; do firewall-cmd --permanent --add-service $i; done;
firewall-cmd --reload
firewall-cmd --list-services        # confirm changes 

On the Client Make sure the required packages are installed as seen above. Use ==showmount== to verify the shared folders.

showmount -e ip_address_server/hostname   # verify /etc/hosts in case of issues

Tell autofs the shared folders to mount and the location of their config file.

# in /etc/auto.master
/shares     /etc/auto.shares        # replaces shares with any file/name

Tell autofs how to mount /shares in /etc/auto.shares

*   -rw     hostname:/shares/&

Mounts all folders exported thanks to the wildcard character. The ampersand matches any subdirectory in the ==/shares==

Start the autofs service

systemctl start autofs
systemctl enable autofs

Confirm folder gets mounted when you navigate to it cd /shares/
