NAME

ntx_ping − send ICMP ECHO_REQUEST packets to network hosts

SYNOPSIS

ntx_ping [ −d device ] [ −t timeout ] host

DESCRIPTION

Ntx_ping interfaces with the downloaded  MVME339 Diagnostic Application to send an ICMP ECHO_REQUEST datagram to host expecting an ECHO_RESPONSE datagram in return.  The datagrams are 64 bytes in length.  If host responds within  timeout seconds, ntx_ping will print "host is alive"; otherwise it will print "no answer from host."
 
Host may be specified by name or by Internet dot notation. 

OPTIONS

−dSet the MVME339 raw device file name.  This option will override the default MVME339 device name of /dev/xedt/mvme338_c0. 

−tThe time to wait in seconds for the host to respond.  The default value is 20 seconds.

WARNINGS

You can only kill the program with a "kill [−signal] process_id" command.  Do not use "kill −9" since the diagnostic channel will not be properly closed.
