Hi Everybody

below is the o/p from tcpdump

06:31:23.417329  In IP (tos 0x0, ttl  64, id 0, offset 0, flags [none], proto: 
TCP (6), length: 46, optlength: 4 ( TS{[bad ptr 0]TSONLY} )) 1.1.1.2.30583 > 
10.1.1.1.23: . 0:2(2) win 0

06:31:23.417358 Out IP (tos 0x0, ttl 255, id 41672, offset 0, flags [DF], proto: 
ICMP (1), length: 60) 10.1.1.1 > 1.1.1.2: ICMP parameter problem - octet 22, 
length 40
        IP (tos 0x0, ttl  64, id 0, offset 0, flags [none], proto: TCP (6), 
length: 46, optlength: 4 ( TS{[bad ptr 0]TSONLY} )) 1.1.1.2.30583 > 10.1.1.1.23: 
[|tcp]


I am trying to generate a IP Option packet(using IXIA) with Time Stamp Set but i 
am getting this  error[optlength: 4 ( TS{[bad ptr 0]TSONLY} ))]  what the error 
suggest i am missing anything from the packet. The packet is getting counted as 
bad ip option.

Kindly suggest.
