Hello,

Obvious question, since this is the Wireshark Users forum, not the TCPDump forum: What does Wireshark tell you when loading this capture?

Thanks,
Jaap

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.
