Listing all Running NonStop TCP/IP Processes
STATS, STATUS, and VERSION commands all return useful configuration and/or
operation data, as follows:

The NAMES command displays all the names currently configured for a specific
object type (SUBNET, ROUTE, or WINDOW).

The INFO SUBNET command displays the subnet name, the name of the SLSA
line, the subnet’s Internet address, the subnet type, and the subnet mask.

The INFO ROUTE command displays the route name, the name of the associated
subnet, the Internet addresses of the destination and the gateway, and the route
type.

The Hint on page 1-7 explains how to use SCF to access information about the
LIFs in the SLSA subsystem.
These commands and responses are explained in detail in Section 4, SCF Reference
.
Listing all Running NonStop TCP/IP Processes
Since there is no NAMES PROCESS command, to obtain a list of all running NonStop
TCP/IP processes, enter one of the following commands at the SCF prompt:
-> LISTDEV TYPE 48
or
-> LISTDEV TCPIP
This command provide the following response display:
Socket Programmatic Interface
The socket interface, provided as part of the NonStop TCP/IP software, uses Guardian
file-system procedures for interprocess communication and provides socket library
routines. Application processes request the NonStop TCP/IP software to create a
socket when needed; the application specifies the type of service desired. Applications
can request TCP, UDP, and raw sockets for use with IP. The NonStop TCP/IP software
returns a socket number that the application uses to refer to the new socket. The
application then (optionally) binds the socket to a specific local address and port, and
sends or receives data on the socket. When the transfer of data is complete, the
application can (optionally) shut down the socket and destroy (close) it.
The socket library routines are based on the socket programmatic interface primitives
in the 4.3BSD release of the UNIX operating system. However, the socket library
routines include extensions to adapt the Berkeley socket interface to Guardian
operating-system features such as nowait I/O.
