NAME

pduclient - program to automate power control of a device

SYNOPSIS

pduclient --daemon daemonhostname --hostname pduhostname --port pduportnumber
--command pducommand

pduclient [{-h | --help}]

DESCRIPTION

This manual page documents briefly the pduclient command.

pduclient is the frontend for lavapdu to issue commands to a Power Distribution Unit
(PDU). Commands include on, off and reboot.

A particular device will be connected to a particular port on a PDU. The lavapdu-runner is
able to control multiple PDUs, specified by hostname. pduclient connects to the
lavapdu-listen daemon which stores the command until the lavapdu-runner daemon is able to
connect to the specified PDU and execute the command on the specified port.

Typically, pduclient will be used from the device configuration file of a LAVA instance,
using lava-dispatcher.

REVERSE LOOKUPS

pduclient needs the hostname of the calling machine to match a DNS reverse lookup. This
means that not only does hostname -f need to resolve to an IP address but that IP address
must resolve to that hostname:

$ dig myhostname.domain
...
192.168.0.56
...

$ dig -x 192.168.0.56
...
myhostname.domain
...

If the second call does not work, you will need to fix the local DNS resolution before
pduclient will operate. Error messages will look something like:
