NS(8) System Manager's Manual NS(8) NAME ns - name server database SYNOPSIS /usr/ipc/mgrs/ns [ -m server ] [ -d ] DESCRIPTION Ns maintains a database of naming information, accessed by qns(7) and other programs. It should be run once from rc(8). The database is accessed through local service ns, or service server if option -m was specified. The file contains instructions for building the database. These in- structions are lines of one of the following forms: #uusys file Read the named uucp Systems file. For entries using caller add a database entry containing system telephone-number,tel uucp,svc For entries using caller or add an entry containing system datakit-address,dk uucp,svc For any other entry, add system uucp,svc #inhost file For each line in the named 4BSD-style internet hosts file, add a database entry of the form ip-address,in hostname host-domain-name,dom #innet file For each line in the named 4BSD-style internet net- works file, add a database entry of the form ip-net-address,in netname #include file Interpret the contents of file in the same format as ns.db. In all cases, file may be followed by a list of value,attribute pairs to be included with any database entries caused by that file. If the filename doesn't begin with it is prefixed with /usr/ipc/lib. Blank lines and lines beginning with followed by a space or tab are ig- nored. Any other lines are taken as literal database entries: a collection of value,attribute pairs separated by spaces. Each line is a single en- try. The database is ephemeral; it is rebuilt whenever ns starts, when re- quested by qns reset, or when ns notices that ns.db or one of the files named therein has changed. Rebuilding can take several minutes, espe- cially on a busy machine. During a rebuild, the server appears active but does not answer requests; calls will block until the rebuild fin- ishes. Ns leaves remarks in file There are more remarks if the -d option was used. FILES SEE ALSO ipc(3), qns(7) NS(8)
