Software Requirements

For example:

Most newer operating systems configure the IPv6 loopback interface, by default. To

determine if the IPv6 loopback interface is configured on the host, use operating system

tools such as ifconfig on UNIX and ipconfig on Windows. On UNIX systems, the device

name of the loopback interface is usually lo or lo0.

NetWorker does not support temporary or link-local IPv6 addresses.

The client backup fails when the IPv6 address for the client is not:

◆

Stored in DNS or in the hosts file.

◆

Added to the client resource.

When the operating system configures the IPv6 loopback interface, ensure that:

◆

The hosts file on each NetWorker host has an entry that associates the IPv6 loopback

interface (::1) with the localhost. Add the IPv6 loopback interface entry before the

IPv4 loopback entry (127.0.0.1 localhost)

For example:

::1 localhost

127.0.0.1 localhost.localdomain localhost

◆

The IPv6 loopback entry must remain in the hosts file when the host is operating in a

pure IPv4, pure IPv6, or dual stack configuration.
