nsrexecd - NetWorker client execution service
is used by NetWorker servers to perform automatic operations on NetWorker
It is currently used by
to start saves and storage node functions on NetWorker
When storage node functions are in use,
commands on the host, and responds to polling requests from the server.
for additional detail on storage nodes.
service is normally started at boot time on each NetWorker client machine.
Since NetWorker servers are usually expected to be clients of themselves,
runs on all NetWorker servers as well.
service exports an RPC-based service to remotely execute NetWorker operations.
All requests must be authenticated, and can optionally be restricted to
specific NetWorker servers.
requests (for example,
and storage node requests are allowed.
When command execution is requested,
first verifies that the request is authenticated, and that it comes from
a valid NetWorker server;
the NetWorker server running on the localhost is always considered
valid, independent from the options supplied to

It then executes the specified command from the NetWorker binary directory.
This directory is normally determined by the location of the
executable, but can be specified on the command line.
As part of the NetWorker server authentication, the server's network
address is mapped to a name. The name is then reverse-mapped to a
network address. The server is authenticated if and only if
the original network address matches the reverse-mapped address.
flag skips the address comparison thereby allowing workarounds
to misconfigured or misfeatured naming systems.
This option should be used with care since it may allow the
NetWorker client to send its data to an unauthorized machine.

If a NetWorker server has multiple network interfaces,
it is often best to list the hostname corresponding to each network interface,
to avoid failed saves.
