What Is NFS?
NFS stands for Network File System and it is used to share files & directories across all systems in the network.
File systems present in the server can be mounted locally on remote host machines. (Client-Server Architecture)
Server Side NFS Configuration Client Side NFS Configuration
1 Install NFS with all its dependencies
2
Configure the /etc/exports file with
directory path and who to share it with
3 Start nfs service and rpcbind service

What Is Squid?
Now let’s understand what is Squid and how administrators can
make use of Squid to improve network bandwidth.

• Squid caches web requests & when another host make a similar request, the response time reduces.
• This results in improved bandwidth for the entire network.
• Squid implements ACL for blocking certain websites/ webpages & improves security by filtering traffic.
What Is Squid?
Squid is a web proxy server which primarily supports HTTP, HTTPS, FTP requests and a few other protocols.
