NAME

       ipmiutil_discover - discover IPMI LAN-enabled nodes

SYNOPSIS

       idiscover [-abegisx]

DESCRIPTION

       idiscover  is  a program that uses IPMI LAN commands to discover any nodes on the LAN that
       are available, by probing the RMCP port (623.)  on those nodes.  This  utility  uses  IPMI
       LAN, so no IPMI drivers are needed.  There are three methods that can be used:
       -a   = broadcast RMCP ping method (default)
       -g   = GetChannelAuthCap command method
       else = specific RMCP ping method

       A  beginning  IP  address  can be specified with -b for broadcast and specific methods. An
       ending IP can be specified for non-broadcast methods.

OPTIONS

       Command line options are described below.

       -a     All nodes, use the broadcast ping method.  This is the default if  no  options  are
              specified.   This will detect the first enabled ethernet interface, and defaults to
              the broadcast address x.x.x.255 (where x.x.x.x is IP address) unless -b is used  to
              specify otherwise.

       -b <ip>
              Beginning  IP  address, required, unless using broadcast with defaults.  This could
              be a specific IP address, or a broadcast address, ending in 255, if  the  broadcast
              method (-a) is used.

       -e <ip>
              Endign  IP  address  of  the range.  Not used for broadcast method.  If this is not
              specified, a range of one IP address matching the beginning IP is assumed.

       -g     Use the GetChannelAuthenticationCapabilities command method over IPMI  LAN  instead
              of the RMCP ping.  Not compatible with broadcast.  This may be useful if the vendor
              BMC does not support RMCP ping for some reason.

       -i eth0
              The interface name to use when sending the probes.  The default is  to  detect  the
              first enabled ethernet interface (e.g. eth0).

       -m     shows  MAC  address.  Uses the broadcast ping method, but uses a raw socket so that
              the MAC  address  can  be  displayed.  This  detects  the  first  enabled  ethernet
              interface, and defaults to the broadcast address 255.255.255.255 like -a.  Using -m
              with raw sockets requires root privilege.

       -r N   Repeat the ping N times to each node.  Default is to send 1 ping per node.

       -x     Causes extra debug messages to be displayed.

EXAMPLES

           idiscover -a -b 192.168.1.255
       Sends a broadcast RMCP ping to discover IPMI LAN nodes on the specified subnet.

           idiscover -b 192.168.1.100 -e 192.168.1.254
       Sends RMCP pings to a range of IP addresses.

           idiscover -g -b 192.168.1.100 -e 192.168.1.254
       Sends GetChannelAuthCap commands to a range of IP addresses.
