How can i make my own assemble/disassemble network packets in perl and would that be raw socket. I know there a tool like netpacket out there but i want to make my own tools.
Within a few minutes of this post, "whiteghost" on Freenode #perl asked:
<whiteghost> How would i assemble/disassemble network packets in perl?
The writing style is very similar (historically in both cases), so I can't say for certain that this is the same person, but I'd bet a month's rent on it. The thing is, from this other IRC comment he made:
<whiteghost> i ry to thng of a tool i can make for exploit bugs in win
+dows but can't think of one right now.
we've all pretty much written him off as a "cracker-wannabe".
So, do what you wish in response to this post, but know that there's a growing group of folks that won't help him.
update: I have strong reason to believe that packet is the same person as well, based on timing of messages here, in email, and on IRC.

What problem are you actually trying to solve (why do you want to deal with network packets this way)? (I'm asking because this looks like a XY Problem.) What have you tried already?

Use unpack and getsockopt. Read kernel manpages like getsockopt(2), socket(7), ip(7), raw(7), tcp(7), udp(7) and internet RFCs like RFC 793.

Use Net::RawIP to send packets.
Use Net::Pcap to get the replies.
Use NetPacket::* to disassemble the replies.
Read up on the perldoc of each.
