Definition of NFS Shares
<!– /wp:heading –>
NFS shares allow a client to access files and directories on a remote NFS server as if they were stored locally. An NFS share can be mounted on a client system, allowing it to read and write files on the remote system.
<!– wp:heading {“level”:3} –>
Pros and Cons of NFS Shares
<!– /wp:heading –>
NFS shares are simple to set up and use, making them a great choice for small to medium-sized networks. One of the primary benefits of NFS shares is that they allow for seamless file sharing between Linux systems. However, NFS shares lack built-in encryption and authentication, making them less secure than other file sharing protocols.
<!– wp:heading {“level”:3} –>
NFS Versions Supported by Linux
<!– /wp:heading –>
Linux supports several versions of NFS, including NFSv2, NFSv3, NFSv4, and NFSv4.1. However, NFSv4.2, the latest version, is not yet supported by Linux. NFSv4 is the most secure version of NFS, as it includes features such as strong authentication and encryption. However, NFSv4 is more complex to set up and use than earlier versions of NFS.

Checking Network Connectivity
<!– /wp:heading –>
Before mounting an NFS share, you need to ensure that there is network connectivity between the client and server. You can check network connectivity using the ping command.
If you cannot ping the NFS server from the client system, check your network configuration and troubleshoot any issues.
<!– wp:heading {“level”:3} –>
Configuring Firewall Rules
<!– /wp:heading –>
By default, NFS traffic is blocked by most Linux firewalls. You need to configure firewall rules to allow NFS traffic through the firewall.
The commands to allow NFS traffic through the firewall vary depending on your Linux distribution. For example, on Ubuntu or Debian, you can allow NFS traffic using the following command:
<!– wp:code –>
sudo ufw allow from [client IP address] to any port nfs
<!– /wp:code –>
On Fedora or CentOS, you can allow NFS traffic using the following command:
<!– wp:code –>
sudo firewall-cmd --add-service=nfs --permanent
sudo firewall-cmd --reload
<!– /wp:code –>

At a small digital marketing agency, the team often collaborates on large files for clients. They were using a cloud-based file sharing system, but found that it was slow and not always reliable. They needed a better solution that would allow them to work on files in real-time.
After researching various options, they decided to use NFS shares to store and share their files. They set up an NFS server on a dedicated machine and installed the NFS client package on all of their Linux machines. They configured firewall rules to allow NFS traffic through the firewall and verified network connectivity between the client and server.
To mount the NFS shares, they used the mount command with the appropriate options. They also edited the fstab file to automate the NFS share mount on Linux boot. This made it easy for the team to access the shared files without having to manually mount the shares each time they booted their machines.
Since using NFS shares, the team has noticed a significant improvement in file access speed and reliability. They are also able to work on files in real-time without having to wait for files to upload and download from a cloud-based system. The team is pleased with their decision to use NFS shares and plans to continue using them in the future.
