The dissector plugin model allows a dissector to be plugged into any dissector table; this means that there already needs to be a dissector that registers that table. Currently, the BOOTP dissector doesn't register any such table, so, as I said, there is currently no mechanism to do what you want to do. You would have to change the BOOTP dissector in order to do that; that would require you to get the Wireshark source, change it, compile it, and distribute that modified version of Wireshark, along with the plugin. Wireshark 1.2 has a limited ability to support custom DHCP options without changing the code. There is a "Custom BootP/DHCP Options" preference, which takes a string of the form 176,MyOption,string;242,NewOption,ipv4 i.e., a semicolon-separated list of options, where each option is a comma-separated list with: option number - a value between 1 and 254 option name - the name for the option option type: string, for an option that's a character string; ipv4, for an option that's an IPv4 address; bytes, for an option that's an opaque blob of bytes. If your option is more complicated than that, this feature cannot support it. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
