NAME

landump −  dump IBM Token-Ring Personal Computer Adapter

SYNOPSIS

/etc/landump [ −d ] interface

DESCRIPTION

Landump is used to freeze the IBM token ring adapter and dump the contents of the adapter’s internal storage for diagnostic purposes. 

The interface parameter is a string of the form “name unit”, for example, “lan0”.  If no options are specified, the adapter is frozen and dumped.  If the -d option is specified, landump runs as a daemon, waiting until a dump is required due to an event internal to the adapter, for instance, adapter hardware failure.  When such an event occurs, landump is notified by the adapter driver and the adapter is frozen and the dump occurs at that time.  The daemon then waits for the next event. 

The contents of the dump are written to a file named interfacecore, for example, “lan0core”, in the current directory. 

DIAGNOSTICS

Messages indicating the specified interface does not exist, or the user is not privileged. 

SEE ALSO

lan(4), rc(8)

BUGS

When run as a daemon, landump doesn’t place itself in the background.  It must be explicitly placed in the background.
