Unless somebody comes up with a good reason *NOT* to make "-e" cause "-x" and "-X" to dump the link-layer header,Actually, I can think of a reason why we might not want to to it - it might break scripts that parse the result of "tcpdump -e -x" *and* that expect the hex dump not to include the link-layer header. The "link-layer header isn't dumped" is documented going back at least as far as tcpdump 3.4: -x Print each packet (minus its link level header) in ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ hex. The smaller of the entire packet or snaplen bytes will be printed. so perhaps we should add a new command-line flag to handle that (or, along the lines of "-t" vs. "-tt" and "-v" vs. "-vv", have "-xx" and "-XX" cause the link-layer header to be printed).
excellent point, imo, and an elegant solution. -- |-----< "CODE WARRIOR" >-----| codewarrior () daemon org * "ah! i see you have the internet twofsonet () graffiti com (Andrew Brown) that goes *ping*!" werdna () squooshy com * "information is power -- share the wealth." - This is the TCPDUMP workers list.
