       serialports - name to serial port database

       serialports NIS or NIS+ maps

       The  serialports database maps a name to a server name and TCP port number that represents
       the serial port connected to the specified terminal server host. The database is typically
       used to map host names to their consoles, but may also be used to provide access to print-
       ers, modems, and the like. The mapping is used when the service is  being  provided  by	a
       network	based  terminal  concentrator. For each name a single line should be present with
       the following information:

	 host-name concentrator-hostname tcp-port-number

       Items are separated by any number of blanks or TAB characters. A pound  sign  (#)indicates
       the  beginning of a comment. Characters between the pound sign and the end of the line are
       not interpreted by routines that search the file.

       This information is used by the cconsole or cssh command  to  establish	connection  to	a
       group  of consoles of a cluster of network hosts. The names that are used in this database
       must be host names, as used in the /etc/inet/hosts database.

       To support Secure Shell connections to node consoles through the cssh command, specify  in
       the  /etc/serialports file the name of the console-access device and the Secure Shell port
       number for each node. If you use the default Secure Shell configuration	on  the  console-
       access device, specify port number 22.

       For  E10000  nodes, the entries are different. This is because E10000 uses netcon for con-
       sole purposes, which operates over a network and executes on the SSP. The following is the
       generic format for the entry.

	 hostname SSPname 23

       The  database  is available from either the NIS or NIS+ maps or a local file. Lookup order
       is specified by the serialports entry in the /etc/nsswitch.conf file, if  present.  If  no
       search order is specified, the default order is nis files.

       Example 1 A Sample /etc/serialports File

       The following is an example /etc/serialports file:

	 # Network host to port database

	 #  NFS server cluster
	 mercury	planets-tc     5001
	 venus		planets-tc     5002

	 # E10000 server cluster
	 cashews	 nuts-ssp-1 23
	 pecans 	 nuts-ssp-2 23

       Example 2 A Sample /etc/nsswitch.conf File Entry

       The following is a typical /etc/nsswitch.conf entry:

	 serialports: nis files
