hey,
I've read anansi's email on this. but i'm having different problems.
when I run 'ruby extconf.rb', it says "ruby headers not found". What does this mean?
Also, do I need to download the original libnet files, and ruby-libnet is just a port?
thanks,
ari

It means the ruby header files are missing 
You need to be specific on exactly what platform you're trying to do this
on.
For example, if you're on Debian or Ubuntu, then you'll need to install the
package "ruby1.8-dev" to get these header files.

could you get it to work to send a SYN packet?
could you test this script:
#!/usr/bin/env ruby
require 'libnet'
$VERBOSE = true
l = Libnet.new
10.times do
l.build_tcp(31337, 80, rand(2 ** 3), 0, Libnet::TH_SYN, 0, 0, 0, Libnet::LIBNET_TCP_H, nil, 0, nil)
l.auto_build_ipv4(Libnet::LIBNET_TCP_H + Libnet::LIBNET_IPV4_H, Libnet::IPPROTO_TCP, "192.168.0.2")
l.auto_build_ethernet(l.hex_aton("00:11:11:94:D4:F5"), Libnet::ETHERTYPE_IP)
ret = l.write
l.clear_packet
puts l.geterror if ret < 0
end
sent,error,written = l.stats
puts ""
puts "Sent: #{sent}"
puts "Error: #{error}"
puts "Bytes Written: #{written}"
# end of file
because it is always segfaulting ruby on my machine

I know multiple people have asked you to drop this signature. I'm adding my voice to the list.
This signature is around 20 lines and you really should try to keep them under 4. This means that one of your messages probably contains as much fluff as actual content.
The real issue is that you waist the bandwidth of thousands of readers every time you send a message to this list. That's just bad manners.
Please, trim the signature.

Sorry about that.
I'm using Mac OS 10.4. Ruby is already installed, so I'm HOPING that the dev files are already installed. However, I keep getting that message. What's going on? Anyone else ever have this problem?
thanks,

I can't require the libnet file. I tried downloading and installing that (like a normal source program), but i couldn't require it. Maybe I installed it incorrectly?
I then attempted downloading ruby-libnet, but I am missing the header files for ruby.

Perhaps you could have a smaller (and slightly less chatoic) spider

For me the real issue is that it is extremely irritating to look at
and scroll past. Maybe if people don't respond to anansi until he
shows that he can be polite to others on this list and get rid of the
stupid spider, he'll get the picture.

A waist is a terrible thing to mind 
Please, trim the signature.
Or replace it with a line of ruby that generates the same characters.

Also, for the missing header files on Mac OS X, I did a locate command, and found the file.
It was in my ruby folder, but once again, I CAN'T access it apparently.
Save me

English is like a pseudo-random number generator - there are a bajillion rules to it, but nobody cares.
Actually, a linefeed character doesn't use up any more bandwidth than
any other character. Thus, the whole "more than 4 lines = wasted
bandwidth" idea is rather arbitrary. A 300-character signature wastes
no more bandwidth if 20 of those characters are linefeeds than if only
3 of them are. If he simply deletes most of the space characters that
are being used to center the spider, thus shifting the spider over to
the left edge, his signature would be using fewer characters than a
signature consisting of 4 full 80-character lines.
Also, I note that you felt the need to quote the entire "waste of
bandwidth" in your reply.

Before the inevitable "how do I do that discussion", let's hope he can just
use this
require'base64';require'zlib';puts Zlib::Inflate.inflate(Base64.decode64

Or not..

True. I think the commodity being wasted isn't really net bandwidth,
though, but rather screen real estate (pixel bandwidth), which can be
a little annoying. I have an old development system that I frequently
use to check my mail on. It has a crappy monitor. Can I scroll
through the fluff? Of course. But I like having as much info on the
screen at one time. Besides, the same artwork on "every" post gets
tiresome. Maybe if it was ruby code that depicted something new every
time

. . . minus the claws. I played around with adding some, but failed.
