nictable(ADM) 19 June 1992 nictable(ADM) Name nictable - process NIC database into channel/domain tables Syntax /usr/mmdf/table/nictable -[ CDT ] [ -d domain ] [ -s service ] [ -t transport ] Description nictable is the tool responsible for taking the hosts.txt table supplied by the SRI Network Information Center and creating domain and channel tables. Options to nictable are as follows: -C The -C option causes the program to generate a channel table on the standard output. -D The -D option causes nictable to create a domain table. It should be combined with the -d option (below), which identi- fies the domain table to be built. -T The -T option creates a ``top'' or ``rootdomain'' table. No trailing domain spec is removed from the LHS entry. -d domain The -d domain option specifies that only hosts in domain should be output. An exception to this is when -d is combined with -T. In this case, all entries will be output except for those in the domain specified with -T. The intention is that you grab all of one domain with -D, and then grab everybody else with -T. -s service The -s service option specifies that only hosts that are listed as supporting service should be output. -t transport The -t transport option is like -s except that it states that only hosts supporting the transport protocol specified should be considered. Typical usage involves two or three invocations: nictable -C < /etc/hosts.txt > smtpchannel nictable -D -d ARPA < /etc/hosts.txt > arpadomain (and optionally) nictable -T -d ARPA < /etc/hosts.txt > rootdomain Value added nictable is an extension of AT&T System V provided by The Santa Cruz Operation, Inc.
