Common uses for ifconfig include setting the IP address and subnet mask of a network interface and disabling or enabling an interface. [1] At boot time, many Unix-like operating systems initialize their network interfaces with shell scripts that call ifconfig. As an interactive tool, system administrators routinely use the utility to display ...
In Linux distributions based on 2.2.x Linux kernels, the ifconfig and route commands are operated together to connect a computer to a network, and to define routes between computer networks. Distributions based on later kernels have deprecated ifconfig and route, replacing them with iproute2. Route for Linux was originally written by Fred N ...
For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9] Like most Unix-based operating systems, Mac OS X also uses ifconfig for more direct control over network interfaces, such as configuring static IP addresses. The Ifconfig command in Linux ...
TCP/IP defines the addresses 192.168.4.0 (network ID address) and 192.168.4.255 (broadcast IP address). The office's hosts send packets to addresses within this range directly, by resolving the destination IP address into a MAC address with the Address Resolution Protocol (ARP) sequence and then encapsulates the IP packet into a MAC frame ...
The IP address of a public server is also important, similar in global uniqueness to a postal address or telephone number. Both IP address and port number must be correctly known by all hosts wishing to successfully communicate. Private IP addresses as described in RFC 1918 are usable only on private networks not directly connected to the internet.
After instantiating a new socket, the server binds the socket to an address. For a Unix domain socket, the address is a /path/filename.. Because the socket address may be either a /path/filename or an IP_address:Port_number, the socket application programming interface requires the address to first be set into a structure.
IP aliasing is associating more than one IP address to a network interface. With this, one node on a network can have multiple connections to a network, each serving a different purpose. According to the Linux Kernel documentation, [1] IP-aliases are an obsolete way to manage multiple IP-addresses/masks per interface.
iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.
