UNIX management commands are available for system managers experienced in managing a UNIX network subsystem. The following table introduces these commands. Command Description arp Controls and displays ARP tables for the specified host. ifconfig Configures or displays network interface parameters, redefines an address for a particular interface, or sets options such as an alias list, broadcast address, or access filter. netstat Displays network statistics of sockets, data link counter aliases, network interfaces, and a host's routing table. nfsstat Displays statistical information about the network file system (NFS) and remote procedural call (RPC) interfaces in the kernel. It can also be used to reinitialize this information. ripquery Requests all routes known by a RIP gateway by sending a RIP request or a POLL command. route Allows you to manipulate the routing table manually. Normally, a system routing table management component, such as GATED or ROUTED, will tend to this task. sysconfig Manages and displays the network attributes in the kernel subsystem configuration. sysconfigdb Manages and displays network attributes in the subsystem configuration table (TCPIP$ETC:SYSCONFIGTAB.DAT). traceroute Displays the route that packets take to a network host. whois Displays user, host, and organization names in the Network Information Center (NIC) database. For more information, see the help available at the TCPIP> prompt. For example, to display ifconfig flags and parameters, enter the following: TCPIP> HELP ifconfig
