L2PING(8)		  BSD System Manager's Manual		     L2PING(8)

NAME
     l2ping — send L2CAP ECHO_REQUEST to remote devices

SYNOPSIS
     l2ping [-fhn] -a remote [-c count] [-i delay] [-S source] [-s size]

DESCRIPTION
     The l2ping utility uses L2CAP ECHO_REQUEST datagram to elicit an L2CAP
     ECHO_RESPONSE datagram from a remote device.

     The options are as follows:

     -a remote
	     Specify the remote device to ping.	 The remote device can be
	     specified by either its BD_ADDR or name.  If name was specified
	     then the l2ping utility will attempt to resolve the name via
	     bt_gethostbyname(3).

     -c count
	     Number of packets to send.	 If this option is not specified,
	     l2ping will operate until interrupted.

     -f	     “Flood” ping, i.e., no delay between packets.

     -h	     Display usage message and exit.

     -i wait
	     Wait wait seconds between sending each packet.  The default is to
	     wait for one second between each packet.  This option is ignored
	     if -f has been specified.

     -n	     Numeric output only.  No attempt will be made to look up symbolic
	     names for host addresses.

     -S source
	     Specify the local device which should be used to send L2CAP
	     ECHO_REQUEST datagrams.  The local device can be specified by
	     either its BD_ADDR or name.  If name was specified then the
	     l2ping utility will attempt to resolve the name via
	     bt_gethostbyname(3).

     -s size
	     Specify the number of payload bytes to be sent.  The default size
	     is 44 bytes.  It is calculated as minimum L2CAP MTU (48 bytes)
	     minus the size of the L2CAP signalling command header (4 bytes).
	     The maximum size is 65531 bytes.  Is is calculated as maximum
	     L2CAP MTU (65535 bytes) minus four bytes of payload reserved for
	     l2ping internal use.  Use this option with caution.  Some imple‐
	     mentations may not like large sizes and may hang or even crash.

EXIT STATUS
     The l2ping utility exits 0 on success, and >0 if an error occurs.

BUGS
     Could collect more statistic.  Could check for duplicated, corrupted and
     lost packets.
