libpcap-ruby

[William Morgan]

Hi all,

I'm having some troubles with libpcap-ruby. The web pages and
documentation don't seem to have been updated since 2001. Is anyone
actively maintaining this?

Thanks,

I've seen this recommended (no update since 2000 but it could just
be that it's stable?):

http://raa.ruby-lang.org/project/pcap/
http://www.goto.info.waseda.ac.jp/~fukusima/ruby/pcap-e.html

(English doc.)


Sorry if it's of no help to you,

It depend what you call stable

read carefully this message [ruby-talk:62437] if you use it (the
modification to make to pcap is evident).

Excerpts (reformatted) from ts's mail of 21 Aug 2004 (EDT):

read carefully this message [ruby-talk:62437] if you use it (the
modification to make to pcap is evident).

I don't think this is the issue I'm experiencing. I'm building an
interface for choosing among wireless networks and it seems like
libpcap-ruby hasn't been updated to deal with 802.11b packets.

E.g. using the included tcpdump.rb script, I get the following message:

/tcpdump.rb:25:in `each_packet': Unknown data-link type (119) (Pcap:capError)

For the time being, I'm running the real tcpdump binary as a child
process through IO.popen() and parsing the output, but that's not an
ideal solution for a number of reasons.

(For libpcap-ruby, it seems like the datalinks[] array in packet.c needs
to be updated, but I'm not enough of a networking guy to know what to
do, or if that's really sufficient.)
