Hello, I would like to request a new link-layer header type value: LINKTYPE_DEV_KMSG_LINUX DLT_DEV_KMSG_LINUX and LINKTYPE_KLOG_LINUX DLT_KLOG_LINUX Linux Kernel Message can be captured on Linux by /dev/kmsg and klogctl. Kernel logs can be useful for analysis Linux and network(etc.) behaviour. Test patch for libpcap for /dev/kmsg is prepared, so you can test it: https://github.com/MichalLabedzki/libpcap/commit/c671673753bba413fe3fc839425162d682289bec (works kernel >= 3.5 and /dev/kmsg, patch need some fixes to check that) Capture format specification is available at: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/Documentation/ABI/testing/dev-kmsg Linux logs can be dissected by Wireshark to improve readability/filtering. There is also klogctl (http://linux.die.net/man/3/klogctl) and /proc/kmsg - but there is different format. So another Linktype can be add.
