Hi Guy Harris ,
armed with what you've learned from that book about the
format of Ethernet headers and IP headers,
look at the first 14 bytes of
data in the packet (you'll now know how that
produces the display
Thanks for the above
suggestion especially the book.
But I'm already
aware of the IP packet format , but some how I'm not able to map the values to
the different header fields .
000000 00 e0 1e a7
05 6f 00 10
000008 5a a0 b9 12 08 00 46 00
000010 03 68 00 00 00 00 0a
2e
000018 ee 33 0f 19 08 7f 0f 19
000020 03 80 94 04 00 00 10 01
000028
16 a2 0a 00 03 50 00 0c
000030 01 01 0f 19 03 80 11 01
Please correct me if
I'm wrong , but as per my understanding , if I have a file "test" with the
above values as content then the below command will generate an IP packet using
these values and add some dummy ethernet header values to
it.
Command
: text2pcap test test123.pcap
So could you please
tell me which values from above would correspond to IP header portions like
:
1) version
2)IHL
3)TOS
4)Total
length
5)Identification
......... etc .
Thanks once again
for your response , hope to get some further inputs again .
Note : This is
related to the mail titled "text2pcap help
needed " .
Regards
,
