Netdude(1)                 OpenBSD Reference Manual                 Netdude(1)



NAME
       Netdude - graphical tcpdump trace file displayer and editor

SYNOPSIS
       netdude [options] [files]

VERSION
       This manpage is describing the Netdude 0.4 series.

DESCRIPTION
       Netdude is the NETwork DUmp data Displayer and Editor. It is a GUI-
       based tool that allows you to make detailed changes to packets in
       tcpdump tracefiles. You can inspect and modify value of every field
       protocol headers of supported protocols, all other data can be modified
       using a hex editor. Protocol support is supplied through protocol
       plugins, see details below to find out how to obtain a list of the
       currently installed protocols. Netdude is readily extendable through
       feature plugins that can contain essentially arbitrary functionality,
       use other libraries, etc. The packet manipulation functionality is
       separated into a backend library, libnetdude.  Consider writing a
       libnetdude application directly, in case dealing with a GUI is too
       cumbersome for your needs.

       For each trace currently being edited, Netdude constantly communicates
       with a tcpdump process to update the familiar tcpdump output that
       corresponds to the trace. This also means that any changes made to your
       local version of tcpdump are reflected in Netdude.

       With the introduction of the 0.4 series, Netdude is now able to handle
       arbitrarily large files. To do this, only a relatively small number of
       packets is loaded into memory at any one time. A lot of effort has gone
       into adding trace navigation support (ie jumps to arbitrary offsets and
       timestamps -- this is mostly handled through the pcapnav library),
       besides a buffering mechanism that can swap in/out trace parts that
       have been modified.

       Netdude offers the following command line options, some of which are
       intended to provide installation directories for configure scripts etc:

OPTIONS
       --debug, -d
            prints out debugging information (only available if debugging
            support was compiled in)

       --ludicrous-debug, -dd
            more debugging output. This reports debugging output for Netdude
            and libnetdude.

       --ridiculous-debug, -ddd
            and even more. Reports debugging output for Netdude, libnetdude,
            and libpcapnav.

       --prefix
            prints out the installation prefix of this Netdude.

       --plugin-dir
            prints out the directory in which feature plugins are installed

       --include-dir
            prints out the directory in which plugin authors can find
            Netdude's .h files

       --proto-dir
            prints out the directory in which protocol plugins are installed

       --plugins
            prints out the names and version of all currently installed
            libnetdude and Netdude protocols

       -h, --help, -h
            displays this help output

       --version
            prints out the version info --version-maj prints out the major
            version number (0.3, 0.4 etc)
