Customizing the Protocols, Services, and Programs (IP and Telco CIP Only)
Applications that use CIP rely on several other configuration files on the host:
• The PROTOCOL file, to identify all available protocols (TCP, UDP, and so on)
• The SERVICES file, to identify all available port-level services (FTP, SMTP, and so on)
• The PORTCONF file, to list the ports monitored by the LISTNER and to identify, for each port,
the program the LISTNER invokes to service requests
PROTOCOL File
The PROTOCOLfile contains the names of the protocols currently supported by the CIP software,
as well as some not currently supported. Applications use the PROTOCOL file to get protocol names
and Internet protocol numbers. When an application calls the functions getprotobyname or
getprotobynumber, the PROTOCOL file provides this information. You do not need to alter this
file.
Each entry has this format:
protocol_name protocol_number PROTOCOL_NAME
Where protocol_name is the protocol name in lowercase, protocol_number is the well-known
Internet protocol number and PROTOCOL_NAME is the protocol name in uppercase. (Because the
functions getprotobyname and getprotobynumber are case sensitive, both uppercase and
lowercase representations of the protocol names are included in the PROTOCOL file.)
Sample PROTOCOL File: SMPLPROT
The site update tape (SUT) comes with a sample PROTOCOL file that is installed into
$SYSTEM.ZTCPIP. The name of this file is SMPLPROT and the contents are shown in the display:
#
# @(#)protocols 1.1 Tandem
#
# Internet (IP) protocols
# This file is never consulted when the yellow pages are running
#
ip 0 IP # internet protocol, pseudo protocol number
icmp 1 ICMP # internet control message protocol
ggp 3 GGP # gateway-gateway protocol
tcp 6 TCP # transmission control protocol
pup 12 PUP # PARC universal packet protocol
udp 17 UDP # user datagram protocol
ipv6 41 IP # internet protocol for v6
icmpv6 58 ICMP # internet control message protocol for v6
Precede comment lines with a pound sign (#).
NOTE: You must add an entry for SCTP to use that protocol. To use SCTP, add this line:
sctp 132 SCTP # stream control transmission protocol
SERVICES File
The SERVICES file contains the Internet port level services that are available with the CIP software.
Applications use the SERVICES file to get the service port numbers and service names. When the
