ServiceIPAddress Option
The ServiceIPAddress option defines a single IP address on which NIFSOCK will listen
for incoming connections. Setting this option overrides the default behavior of
accepting connections on all IP addresses.
The IP address must contain a single, literal IPv4 or IPv6 address or a single
hostname. When a hostname is used, the hostname must be resolvable by the
getaddrinfo() TCP/IP library function to a SINGLE IP address. If the hostname cannot
be resolved, the NIFSOCK will not start. If the hostname resolves to multiple
addresses, connections will work intermittently.
On startup, NIFSOCK attempts to access the address specified by ServiceIPAddress.
If there is a problem accessing the specified address, a critical error is logged to the
Piccolo log file and NIFSOCK does not start. If no problem is detected with accessing
the specified address, a message indicating which address is being used for input is
logged to the Piccolo log file at log level CLOG_TCP (128).
In addition to a log entry, the successful activation of ServiceIPAddress can be verified
using the PIPECP STATUS NIFS command. The word “only” is added to the IP
address for each NIF that is monitoring a single incoming connection. The following
sample output shows two NIFSOCK instances, one of which is constrained by
ServiceIPAddress:
C:\rsc\bin>pipecp status nifs
NIF name Type Process Pri Links Address
-------- ---- ------- --- ----- --------
nifnormal TCP/IP 6c4 10 0 10.1.23.4, 10.5.67.8 (port 5000)
nifsipopt TCP/IP 6fc 10 0 10.1.23.4 only (port 5001)
The same service port can be used with different ServiceIPAddress values with no
interaction between the different ServiceIPAddress environments, provided the
operating system and installed TCP/IP networking software allow it.
