The hardware part consists of an Ethernet card in case of LAN or a modem in internet. It just requires a module in a standard manner, connecting the card The kernel code for TCP/IP is written in such a way that it is very simple to "slide in" drivers for many kind of real (or virtual) communication channels without bothering too much about the functioning of the network and transport layer code. It is possible to divide the networking code into parts - one which implements the actual protocols (the /usr/linux/net/ipv4ĭirectory) and the other which implements device driver various network hardware.(/usr/src/linux/drivers/net ). Internally Linux kernel implements the TCP/IP protocol stack. One could also see Linux as one of the most 'safest and secure' Networking Operating system presently available in the market. It is apparent that support for networking is inherent to the Linux kernel. The document intends only to show some essential points As a note, the driver development was done in CĪnd as a module, so I assume its readers to be significantly exposed to C and l This article will help the reader to understand and develop a network driverįor an ethernet card in Linux.
