This information is stored in various files in the /etc/sysconfig directory. Specifically, the tabs enable you to do the following:ĭevices-Lets you add a new network interface, specify the IP address of the interface, and activate the interface. You can configure various aspects of your network through the four tabs that appear along the top of the dialog box. This command shows the network-device names, as well as statistics on the number of packets sent and received for a specific device.įigure 6-6: Configuring a TCP/IP Network with the Red Hat Network Configuration Tool. If you want to see the names of installed network devices on your system, try the following command: cat /proc/net/dev Chapter 13 covers this subject in detail. PPP is popular in dial-up networks, in which you use a modem to dial in to an Internet host (typically, a system at your work or your ISP) and establish a connection to the Internet. In fact, the whole point of the loopback device is to allow network applications to work, as long as the communicating processes are on the same system.

SLIP is not used much anymore it has been superseded by PPP. Red hat linux ppp configuration serial#If you use a second serial port for SLIP, it gets the device name sl1. SLIP is used for establishing a point-to-point link to a TCP/IP network. Sl0-The first serial port configured for Serial Line Internet Protocol (SLIP) networking. If you have more serial ports configured for PPP networking, they are assigned device names ppp1, ppp2, and so on. ![]() Ppp0-The first serial port configured for a point-to-point link to another computer, using Point-to-Point Protocol (PPP). If you have more Ethernet cards, they get device names eth1, eth2, and so on. This device is used for efficient handling of network packets sent from your system to itself (when, for example, an X client communicates with the X server on the same system).Įth0-The first Ethernet card or 802.11b wireless network card. Following are the common network-device names in Linux: The networking devices, however, have names defined internally in the kernel no files for these devices exist in the /dev directory. For most devices, Linux uses files in the /dev directory. ![]()
