How to analysis a packet?

Ruby
1

Hello all, I need to send SNMP packets and check whether SNMP-Response
packets
are received. I was looking at rubyforger, which seems to allow me to
do this quite easily. However, rubyforger is dependent on ruby pcap
and
ruby pcap doesnt seem to install on windows(ruby-pcap-0.6.tar). Has
anybody successfully
done so or has a suggestion ?
Thanks-

As far as I know , you can find pcap for windows at www.winpcap.org .
You should try to install that , and then try to install ruby-pcap .

PacketFu just got up-revved yesterday for Windows goodness, and it
should easily be able to look for a SNMP response for you. Something
like…

irb -r packetfu-shell.rb
cap = Capture.new(:iface => ‘whatever your interface name is’)
cap.show_live(:filter => ‘port 161’)

…ought to get you started.
