Description-en: nss module providing fallback resolution for the current hostname
This package contains a plugin for the Name Service Switch, providing host
name resolution for the locally configured system hostname as returned by
gethostname(2). It returns all locally configured public IP addresses or -- if
none are configured, the IPv4 address 127.0.1.1 (which is on the local
loopback) and the IPv6 address ::1 (which is the local host).
.
A lot of software relies on that the local host name is resolvable. This
package provides an alternative to the fragile and error-prone manual editing
of /etc/hosts.
.
Installing this package automatically adds myhostname to /etc/nsswitch.conf.
