Purpose:<\/h3>\n<\/div>\n
\n
\n

Receive TCP\/IP messages from remote networks and set specified CyFlex events based on the message content.\u00a0<\/p>\n<\/dd>\n<\/dl>\n

Enter:<\/h3>\n

ev_tcp_receive<\/strong> \u00a0[subnetMask] [–log ]\u00a0<\/p>\n

ev_tcp_receive can be started by typing the program name, or optionally by typing the program name plus subnet mask. This option allows ev_tcp_receive to filter client notes from which it can receive sent event.<\/p>\n

The subnet mask follows the usual format for IP version4. A system error will occur in the execution if the value of the IP in any of the octets is more than the permitted 255 or is invalid.<\/p>\n

Where:<\/h3>\n
\n
\n\n\n\n<\/colgroup>\n\n\n\n
subnetMask<\/td>\nOptional. Specify a string representing the subnet mask (e.g., “198.201.0.0”) for filtering client IP addresses.\u00a0<\/td>\n<\/tr>\n
–log<\/td>\nOptional. Specify this option to enable logging to a timestamped file in \/data\/errors\/.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/dd>\n<\/dl>\n

Example:<\/h3>\n
\n
\n

For a host within a network with IP address 198.201.78.5, the subnet mask typed at the prompt can be any of the following:<\/p>\n

198.0.0.0 —-> This allows all client nodes having 198 in the first octet
\n198.201.0.0 —-> This allows only clients with IP addresses matching the first two octets
\n198.201.78.0 —-> Allows only clients with IP addresses matching the first three octets<\/p>\n

The program can then be launched by typing any of the following kinds of option:<\/p>\n

ev_tcp_receive<\/strong> \/\/for default execution only
\nev_tcp_receive<\/strong> 198.201.0.0
\nev_tcp_receive<\/strong> 198.201.78.0<\/p>\n<\/dd>\n<\/dl>\n

Notes:<\/h3>\n
\n
\n

The program runs indefinitely and should be executed in the background. Invalid subnet masks will result in errors and prevent socket creation.<\/p>\n<\/dd>\n<\/dl>\n
