DKLOAD(1M) DKLOAD(1M)
E-29 CommKit Host Interface, Release 4.0
NAME
dkload – load test the host interface and check for errors
SYNOPSIS
dkload destination.dkload [–s size] [–n iterations] [-l logfile]
DESCRIPTION
dkload is a program used to test whether the host interface to an AT&T data switch is operative and may be
used to load test the interface. dkload sets up a virtual circuit between two data switch hosts and then sends
and receives fixed sized data messages over the circuit. dkload must be run as root.
dkload may call any host in a data switch network that has the service dkload defined in its srvtab(4). The
host is specified by the destination on the command line [see dkhosts(4)].
The following flags are recognized by dkload:
–s size The message size that will be read and written. The default is 512 and the
maximum size is 10240. A blank must separate the flag from the size.
–n iterations The number of iterations that dkload should run. The default is zero and is
interpreted as a request to run infinitely. A blank must separate the flag from
the iterations.
–l logfile File where timing information and error messages are logged. The default
logfile is /tmp/dkloadlog.
When running dkload between two data switch hosts, the path specified for
logfile must exist on both hosts. The path on the local machine is relative to
the current directory, while the path on the remote machine is relative to the
root directory (/). A logfile will be opened on each host, and each dkload
process will write to the logfile on the host on which it is executing.
When the local and remote host are the same, one logfile will be opened, and
the dkload processes on both sides of the virtual circuit will write to the one
file.
The default logfile will be used on the remote host if the remote dkload
cannot open the requested file for writing.
Multiple Interfaces
If multiple interface boards are installed on the originating host dkload will use the default processing to
select the interface for the out-going call. See dkdial(3X) and authorize(1M) for more information.
