Solaris Jedi: A quick way to check UDP ports on Solaris
Ever need a quick way to check what UDP connections are active on your Solaris server? I recently had to validate a scanner's report that we had an unnecessary service running on UDP port 177. Unfortunately, Solaris does not yet ship with lsof as a standard tool, so it requires the use of netstat(1M).

jack.udp

JACK.UDP(1)															       JACK.UDP(1)

NAME

       jack.udp - JACK UDP Transport Client

SYNOPSIS

       jack.udp [options] send|recv

OPTIONS

       -b : Set the ring buffer size in frames (default=4096). -c : Set the client name (default=jack.udp-PID). -n : Set the number of channels,
       and therefore the number of JACK ports (default=2). -p : Set the port number (default=57160). -r : The remote host name, for use in send
       mode (default="127.0.0.1").

DESCRIPTION

       jack.udp is a UDP audio transport mechansim for JACK. The send mode reads signals from a set of JACK input ports and sends UDP packets to
       the indicated port at the indicated host at a rate determined by the local JACK daemon. The recv mode reads incoming packets at the indi-
       cated port and writes the incoming data to a set of JACK output ports at a rate that is determined by the local JACK daemon.

       This transport mechanism is unreliable. Both send and recv clients will report buffer overflow and underflow occurences, and recv clients
       will report dropped and out-of-order packets, and shutdown on channel mismatch packets. In practice this mechanism can be made highly reli-
       able over local networks.

       jack.udp implements no connection logic, use jack.plumbing(1) instead.

EXAMPLE

	   192.0.0.1:~$ jack.udp -r 192.0.0.2 send
	   192.0.0.2:~$ jack.udp recv
