Hello all:
I know netwox and nemesis are very good network packet injection
utilities. I can use them to create an ip packet with fragment information
easily, for example:
netwox 39 -l "127.0.0.1" -m "127.0.0.1" -e 1111 -j 225 -h -i 0 -q
"1100110011001100"
and output is:
IP___________________________________.

| length | checksum |
|______0x0010=16__|____0xB8A9=47273__|
11 00 11 00 11 00 11 00 # ........
with '-h' and '-i' option, I can specify this is an ip fragment and it's
offset is 0, but when I want to create an ipv6 packet with fragment
information, I meet some trouble. It seems that no matter netwox or nemesis,
it can not create this kind of ipv6 packet.
Do you know how to create ipv6 packet with fragment information? Can you
help me?
