Windows and Linux are different operating system but both can talk to each other using TCP/IP networking and special software program such as Samba. Samba is used for sharing files and printers with Linux and vise versa. Following list summaries the application name which you can use to access Your Linux server/system from Windows system.

WAN Protocols
HDLC, PPP, and Frame-Relay
What is HDLC?
HDLC stands for High-Level Data Link Control protocol. Like the two other WAN protocols mentioned in this article, HDLC is a Layer 2 protocol . HDLC is a simple protocol used to connect point to point serial devices. For example, you have point to point leased line connecting two locations, in two different cities. HDLC would be the protocol with the least amount of configuration required to connect these two locations. HDLC would be running over the WAN, between the two locations. Each router would be de-encapsulating HDLC and turning dropping it off on the LAN. Continue reading
Configuring Network Address Translation
When you configure NAT, it is sometimes difficult to know where to begin, especially if you are new to NAT. These steps guide you to define what you want NAT to do and how to configure it: Continue reading
Classful vs Classless Addressing
All IP addresses are composed of two parts :
Network (or prefix)
Host (or Node)
Originally, all IP addresses were classful – they belonged to Class A, B, C or D. Class D is for Multicast and is rarely used. Class E is reserved and is not currently used.
The fixed boundaries of classful addressing greatly limited the flexibility and number of addresses that can be assigned. Therefore, these boundaries were made to be fluid, and instead of Classes, the Network address was allowed to take any number of bits in the 32-bit address space. They call this the “prefix” and it is denoted with a slash ( / ) followed by the length in bits. For example, a Class C address has 24 bits for the network address, which in the classless world would be called a /24 address.
