hostname | Display workstation host name. This command is available under UNIX System Services. |
ifconfig | Display all TCP/IP network configuration values. This is useful when determining whether or not an IP interface is active. (Linux operating systems only) |
ipconfig | Display all TCP/IP network configuration values. This is useful when determining whether or not an IP interface is active. (All operating systems except Linux) |
netstat | Display protocol statistics and TCP/IP network connections. This is used for obtaining information about your own IP interfaces, for example, listing IP addresses and TCP/IP routing tables used on your workstation. This command is available under UNIX System Services. |
nslookup | Display information on Domain Name System (DNS) name servers. This command is available under UNIX System Services. |
ping | Verify connection to a remote computer or computers. The equivalent command for IPv6 is ping6. This command is available under UNIX System Services. |
tracert | Trace TCP/IP path to a requested destination. This is useful for determining whether a problem exists with an intermediate node or not. The equivalent command for IPv6 is tracert6. (Windows operating systems only) |
traceroute | Trace TCP/IP path to a requested destination. This is useful for determining whether a problem exists with an intermediate node or not. (All operating systems except Windows) |
