We plan on testing ldm on a diskless machine > with a small queue to see how fast it can go. The ldm checks to see if a portmapper is running on the local system. It does this by calling clntcp_create() on the local system, attempting to create a connection to the portmapper. Apparently, on your system your're not running a portmapper and the timeout for the clnttcp_create() function is about seven minutes. That timeout is ridiculous. It might be settable, somehow. Consult with your system administrator and/or complain bitterly to the OS vendor. > Thanks, > Jeff > ------------------------------------------------------------------------------ > Jeff Masters (address@hidden) ( ) > Chief Meteorologist /\ Home of the ( ) > The Weather Underground, Inc. /\ / \ /\ /\ ( ) > 300 N.
