15.02.2014, 18:44, "Daniel H. Bahr" <dhbahr () gmail com>:Hello everyone, I'm in need of accessing the tsval value of the options field in the tcp header... i've been checking the tcp.h and did not find anything that helped me. Does any body know how to do it?Greetings. TCP options are a particular case of TLV class of encodings. This most likely implies that TCP options are opaque to libpcap. To access one or more TCP options it is necessary to have some code like that in tcpdump, print-tcp.c around line 500. -- Denis Ovsienko _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
