MKHPATH(8) Local MKHPATH(8)NAMEmkhpath - produce path data from an /etc/hosts file
SYNOPSIS
/usr/lib/smail/mkhpath [ -n netname ] [ -c cost ] [ -g gateway ] [ -d ]
[ - | filename ]
DESCRIPTION
Mkhpath takes as input a hosts file, in the format of the 4.3BSD file
/etc/hosts, and creates path data suitable for use by a smail(8)
pathalias router (see smail(5) for information on routers). The output
is also suitable for merging in with the output of pathalias(8), and
can be made suitable as input to pathalias.
The hostnames localhost and loghost are ignored, as are any domain
names (names containing dot characters).
This command is useful for sending information about a network's con‐
nectivity to hosts that are not on that network. As a general rule,
the smail gethostbyname router driver precludes the need for this tool.
OPTIONS
The following options are recognized by mkhpath:
-n netname
Generate output which is suitable as input to pathalias(8) as a
description of an interconnected network named netname connect‐
ing together all hosts named in the hosts file.
-c cost
Set the cost for the network gateway to cost. This may be any
valid pathalias cost expression and is only useful with the -n
option.
-g gateway
Set the gateway for all of the hosts in the hosts file to gate‐
way. This can be used either with or without the -n option. If
neither -g nor -n are used, then the local host is assumed to
connect to all of the hosts directly.
-d Only use lines that contain a domain name (i.e., a name contain‐
ing one or more dots) as one of the names for a host. Such
domain names are not used themselves, but lines that do not con‐
tain any domain names are ignored.
If a filename argument is used, then the host information is read from
this file. If an argument of - is specified instead, then the standard
input is used. Otherwise the file /etc/hosts is used to obtain host
information.
