libnetdude 0.11 (Default branch)
libnetdude is the packet manipulation backend ofthe Netdude trace file editing framework. Itallows you to perform trace file manipulations ata much higher level of abstraction than codewritten directly for the pcap interface. It alsosupports plugins (dynamically loaded libraries)that can essentially do whatever the programmerdesires. When developers write their packetmanipulation code as libnetdude plugins, thisinstantly allows other developers to use theirtools. It provides data types and APIs for themost common situations when dealing with libpcaptrace files: trace files of arbitrary size,packets, network protocols, packet iterators, andpacket filters, just to name a few. License: BSD License (revised)Changes:
This release adds support for VLAN-tagged packets. It fixes a small number of bugs in the handling of unused space in packets.Image

trpt

trpt(8) 						      System Manager's Manual							   trpt(8)

NAME

       trpt - Transliterates protocol trace

SYNOPSIS

       trpt [-afjst] [-p address]

FLAGS

       Print  the values of the source and destination addresses for each packet recorded, in addition to the normal output.  Follows the trace as
       it occurs, waiting briefly for additional records each time the end of the log is reached.  Lists the protocol control block addresses  for
       which  trace  records  exist.   Shows only trace records associated with the protocol control block specified in hexadecimal by the address
       variable.

	      You must include a space between the -p flag and the address variable when you specify this flag.  Prints a detailed description	of
	      the  packet-sequencing  information, in addition to the normal output.  Prints the values for all timers at each point in the trace,
	      in addition to the normal output.

DESCRIPTION

       The trpt command, used for debugging sockets, queries the buffer of Transmission Control Protocol  (TCP)  trace	records.   The	TCP  trace
       record  buffer is created when a socket is marked for debugging with the setsockopt(2) subroutine.  The trpt command queries the buffer and
       then prints a description of the trace records.

       When you specify no options, the trpt command prints all the trace records found in the system and groups them according  to  their  TCP/IP
       connection Protocol Control Block (PCB).

       If you are debugging a system file other than the default, the system argument can be used to replace the default.

       Before  you  can use the trpt command, you must do the following: Isolate the problem and mark for debugging the socket or sockets involved
       in the connection.  Find the address of the protocol control blocks associated with these sockets by using the netstat -aA command.   Then,
       you  can  run  the  trpt  command, using the -p flag to supply the associated protocol control block addresses. You can specify multiple -p
       address flags with a single trpt command.

       The -f flag can be used to follow the trace log once it is located.  The -j flag can be used to check for the presence of trace records for
       the socket in question.

       If the system image does not contain the proper symbols to find the trace buffer, the trpt command cannot succeed.
