The SOCKET statement defines an IP address and port combination that is being used for TCP/IP over NJE at some node in the network, including the local node. You need to define the following two types of SOCKETs:

• Sockets defined for the local node (for example, specifying NODE=ownnode) that are used by NETSRV devices to listen for incoming NJE connections
• Sockets defined for other nodes, which will be used on a $SN command to initiate a connection between this node and a specific IP address and port at another node.

You can specify the IP address (IPADDR=) in many different formats. You can specify an explicit IPv4 address in dotted-decimal format (for example, 9.57.1.33); you can specify and explicit IPv6 address in hex=colon format (for example 1234::5678), or you can use a symbolic name (for example, pok.ibm.com). You can specify the port (PORT=) as any number in the range of 1-32767; typically you can use the default. You can use the SECURE= parameter to define whether SSL/TLS is to be used. When SECURE=NO is used (no SSL or TLS), the default PORT= value is the value associated with the VMNET protocol, typically 175. When SECURE=YES is specified, the default is the value associated with the NJE-SSL protocol, typically 2252. If you have not defined any sockets in your init deck, you can use the $ADD SOCKET(xxxxxxxx) command to create them.
