VMS IP Commands
As the system administrator ("SYSTEM"), one can use and maintain TCP/IP services in various ways. The below are all CLI commands, with DCL. (Note: Exclamation marks, i.e. "!", denote comments.)
To display the current configuration, the most rapid way would be by invoking the following command: $ SHOW NETWORK
With the following, detailed information is shown for the TCP/IP configuration(s) in particular:
$ SHOW NETWORK /FULL "TCP/IP"
(For one thing, it'll also list active ports in use.)
One of the most common and probably the easiest ways of setting up TCP/IP networking, is with the following utility: $ @SYS$SYSROOT:[SYSMGR]TCPIP$CONFIG.COM
Or, via the UNIX-like command: $ TCPIP
So, for example: $ TCPIP IFCONFIG (...) ! whatever ! desired ! options & ! values
$ TCPIP PING 192.168.1.1 ! just as an ! example
$ TCPIP TRACEROUTE howtonetworks.net ! idem ditto
$ TCPIP NETSTAT -A
VMS IP Commands
All the ethernet adapters should typically be listed as EW* devices, which can be found by typing:
$ SHOW DEVICES EW
With advanced descriptions, add the /FULL qualifier, like so: $ SHOW DEVICES /FULL EW
For just one device, say EWA0: $ SHOW DEVICE /FULL EWA0
Alternatively, this also works: $ TCPIP SHOW INTERFACES /FULL $ TCPIP IFCONFIG -A
