Hi Martin, Yes, there is a bug on man (forget to update after last update... https://code.wireshark.org/review/2658 ) You can open a bug or push directly on fix. Cheers On Mon, Mar 27, 2017 at 9:46 AM, Martin Sehnoutka <msehnout () redhat com> wrote:
Hello, I'm investigating why Wireshark is dropping packets when capturing over loopback and I think the man page is wrong with the default snaplen. It says that the default size is 65535, but if I'm not mistaken the default size is set in capture_opts.c which leads to WTAP_MAX_PACKET_SIZE in wiretap/wtap.h and the value is 262144. $ grep snaplen capture_opts.c capture_opts->default_options.has_snaplen = FALSE; capture_opts->default_options.snaplen = WTAP_MAX_PACKET_SIZE; $ grep WTAP_MAX_PACKET_SIZE wiretap/wtap.h #define WTAP_MAX_PACKET_SIZE 262144 When running wireshark it indeed seems like the default value is 262144 (it drops the same amount of packets, as it does without specifying any snaplen). Should I fill in a bug report? Regards, -- Martin Sehnoutka | Associate Software Engineer PGP: 5FD64AF5 UTC+1 (CET) RED HAT | TRIED. TESTED.
