please advice

Thank you

# snoop -r -s 1600 "port 500"
should give you communication b/w server and client. Then you analyse the sequence for communication taking place. If you running client and server on same machine then you need to provide extra option " -d lo0 ". Additionally you can write that output to a file using one more option " -o snoop500.pcap " and then use "Ethereal" tool to further analyse commuication

tcpconnect

TCPCONNECT(1)						      General Commands Manual						     TCPCONNECT(1)

NAME

       tcpconnect - general TCP/IP client

SYNOPSIS

       tcpconnect [-irv] [-l localaddr] host port

DESCRIPTION

       tcpconnect  creates  a TCP/IP connection to a server running on the machine host, listening to port port.  It then reads standard input and
       sends to the remote server, and data received from the server is printed to standard output.  When end-of-file is reached on both  standard
       input and the TCP/IP connection, tcpconnect terminates.

OPTIONS

       -i     Terminate at end-of-file on standard input; don't wait for the server to close the connection.

       -r     Terminate when the remote server closes the connection; don't wait for end-of-file on standard input.

       -v     Verbose mode.  Prints a message to standard error when the connection has been established.

       -l addr:port
	      Bind  the local end-point of the connection to IP address addr, TCP port port.  Either the IP address or the port, but not both, may
	      be left out, meaning that the operating system gets to choose that part by itself.

SEE ALSO

       tcplisten(1), telnet(1), tcpbug(1).

BUGS

       The names of the options are not yet finalized, and may change at a future release.
