NAME    [Toc]    [Back]

     l2ping -- send L2CAP ECHO_REQUEST to remote devices

SYNOPSIS    [Toc]    [Back]

     l2ping [-fh] -a BD_ADDR [-c count] [-i delay] [-S BD_ADDR] [-s size]

DESCRIPTION    [Toc]    [Back]

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

     The options are as follows:

     -a BD_ADDR
	     Address of remote device to ping.	Example: -a 00:01:02:03:04:05.

     -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.

     -S BD_ADDR
	     Send L2CAP ECHO_REQUEST from local device that has BD_ADDR.
	     Example: -S 00:05:04:03:02:01.

     -s size
	     Specify the number of payload bytes to be sent.  The default is
	     64.  The maximum size is 65531.  Use this option with caution.
	     Some implementations may not like large sizes and may hang or
	     even crash.

BUGS    [Toc]    [Back]

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

DIAGNOSTICS    [Toc]    [Back]

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