thank you for the response Kevin and Bakul, but neither tcptrace nor ethereal/wireshark is what I'm looking for. As I said, the application I was using was drawing single IP packet header similar to what is presented in RFC791 - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |Version| IHL |Type of Service| Total Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Identification |Flags| Fragment Offset | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Time to Live | Protocol | Header Checksum | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Source Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Destination Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Options | Padding | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ But a) graphically with colors, b) with actual packet/header data from the captured IP packet. Actual result looked similar to this picture - https://www.ibm.com/support/knowledgecenter/en/ssw_aix_71/com.ibm.aix.networkcomm/figures/comma35.jpg thank you 3des On 02.11.2017 02:38, Kevin Oberman wrote: > On Wed, Nov 1, 2017 at 2:46 PM, DES <3des@inx.su <mailto:3des@inx.su>> > wrote: > > Hello FreeBSD-Net, > > does anybody remember, around year 2004, there was a software > application available (either as port, or package).
