Configuring and Administering the BIND Name Service
Updating Network-Related Files
Updating Network-Related Files
After you configure your system to use BIND, the following
network-related configuration files require fully-qualified domain names
for all hosts outside your local domain:
/etc/hosts.equiv
$HOME/.rhosts
/var/adm/inetd.sec
$HOME/.netrc
To Update /etc/hosts.equiv and $HOME/.rhosts
Flat or string-type host names that are not hosts in the local domain
must be converted to fully qualified domain names in the
/etc/hosts.equiv file and in all $HOME/.rhosts files.
The shell script convert_rhosts, found in /usr/examples/bind,
accepts input conforming to the syntax in hosts.equiv and converts it to
fully qualified domain names. Instructions for using this utility are in
the comments at the beginning of the script itself.
To Update /var/adm/inetd.sec and $HOME/.netrc
Flat or string-type host names that are not hosts in the local domain
must be converted to fully qualified domain names in the
/var/adm/inetd.sec file and in all $HOME/.netrc files. No automated
utility exists for performing this task, so you must do it manually.
To Update /etc/hosts
To provide an alternate means of lookup if the name server is down, you
should maintain a minimal /etc/hosts file. It should contain the host
names and the internet addresses of the hosts in your local domain.
