msgcache - Cache client messages for later pickup by hobbitfetch
msgcache implements a Hobbit message cache. It is intended for use with
clients which cannot deliver their data to the Hobbit server in the
normal way. Instead of having the client tools connect to the Hobbit
server, msgcache runs locally and the client tools then deliver their
data to the msgcache daemon. The msgcache daemon is then polled
regularly by the hobbitfetch(8) utility, which collects the client
messages stored by msgcache and forwards them to the Hobbit server.
NOTE: When using msgcache, the BBDISP setting for the clients should be
BBDISP=127.0.0.1 instead of pointing at the real Hobbit server.
Clients delivering their data to msgcache instead of the real Hobbit
server will in general not notice this. Specifically, the client
configuration data provided by the Hobbit server when a client delivers
its data is forwarded through the hobbitfetch / msgcache chain, so the
normal centralized client configuration works.
However, other commands which rely on clients communicating directly
with the Hobbit server will not work. This includes the config and
query commands which clients may use to fetch configuration files and
query the Hobbit server for a current status.
The download command also does not work with msgcache. This means that
the automatic client update facility will not work for clients
communicating via msgcache.
Defines the IP-address and portnumber where msgcache listens for
incoming connections. By default, msgcache listens for
connections on all network interfaces, port 1984.
Restricts which servers are allowed to pick up the cached
messages. By default anyone can contact the msgcache utility
and request all of the cached messages. This option allows only
the listed servers to request the cached messages.
Defines how long cached messages are kept. If the message has
not been picked up with N seconds after being delivered to
msgcache, it is silently discarded. Default: N=600 seconds (10
Run as a daemon, i.e. msgcache will detach from the terminal and

is started by hobbitlaunch(8) which is the normal way of running
