Last checked against version &net-tools-contversion;. arp, dnsdomainname (link to hostname), domainname (link to hostname), hostname, ifconfig, nameif, netstat, nisdomainname (link to hostname), plipconfig, rarp, route, slattach and ypdomainname (link to hostname) arp is used to manipulate the kernel's ARP cache, usually to add or delete an entry, or to dump the ARP cache. dnsdomainname shows the system's DNS domain name. domainname shows or sets the system's NIS/YP domain name. hostname prints or sets the name of the current host system. The ifconfig command is the general command used to configure network interfaces. nameif names network interfaces based on MAC addresses. netstat is a multi-purpose tool used to print the network connections, routing tables, interface statistics, masquerade connections and multicast memberships. nisdomainname shows or sets system's NIS/YP domain name. plipconfig is used to fine-tune the PLIP device parameters, hopefully making it faster. Akin to the arp program, the rarp program manipulates the system's RARP table. route is the general utility which is used to manipulate the IP routing table. slattach attaches a network interface to a serial line, i.e.. puts a normal terminal line into one of several "network" modes. ypdomainname shows or sets the system's NIS/YP domain name.
