YaST uses the command modify_resolvconf check to find out whether resolv
.conf has been modified and subsequently warns the user that changes will be lost
after restoring the file. Apart from this, YaST does not rely on modify_resolvconf,
which means that the impact of changing resolv.conf through YaST is the same
as that of any manual change. In both cases, changes have a permanent effect. Modifi-
cations requested by the mentioned services are only temporary.
/etc/hosts
In this file, shown in
signed to hostnames. If no name server is implemented, all hosts to which an IP connec-
tion will be set up must be listed here. For each host, enter a line consisting of the IP
address, the fully qualified hostname, and the hostname into the file. The IP address
must be at the beginning of the line and the entries separated by blanks and tabs.
Comments are always preceded by the # sign.
Example 30.6 /etc/hosts
127.0.0.1 localhost
192.168.0.20 sun.example.com sun
192.168.0.1 earth.example.com earth
/etc/networks
Here, network names are converted to network addresses. The format is similar to that
of the hosts file, except the network names precede the addresses. See
"/etc/networks"
Example 30.7 /etc/networks
loopback 127.0.0.0
localnet 192.168.0.0
/etc/host.conf
Name resolution—the translation of host and network names via the resolver library—is
controlled by this file. This file is only used for programs linked to libc4 or libc5. For
