NAME amservice - run an amanda service on a client

SYNOPSIS amservice hostname auth service [-f input_file] [-o configoption]...

DESCRIPTION Amservice execute an Amanda service on a client. It can be used without amanda server configuration (amanda.conf and disklist). It can be used to check communication between a server and a client. Amservice reads stdin to capture the REQ packet to send to the client.

See the amanda(8) man page for more details about Amanda.

OPTIONS hostname The hostname of the client.

auth The auth to use, one of: bsd, bsdudp, bsdtcp, ssh, rsh or krb5. The client must be configured with this auth.

service The amanda service to execute on the client. One of noop, selfcheck or sendsize.

-f input_file Use the file input_file instead of stdin to read the REQ packet from.

-o configoption See the "CONFIGURATION OVERRIDE" section in amanda(8).

EXAMPLE The noop service is easy to execute because it does not require a REQ packet: amservice hostname bsdtcp noop < /dev/

The example executes the noop service on the client using bsdtcp auth. This is useful for debugging connection problems. It print an OPTIONS line upon success.

It is more difficult to execute the selfcheck or sendsize service, as these require a valid REQ packet. If you have already uccessfully run amanda, you can find valid REQ packets in the amandad.*.debug files.

EXIT CODE The exit code of amservice is one of: 0 = success 1 = error executing amandad on the client.

As amservice doesn´t parse the REP packet, it can only detect failures in executing amandad on the client. amservice can exit with value 0 even if the user is not authorized to execute the service. An error message will be printed.
