Add PCAP_IF_NO_INJECT and PCAP_IF_NO_CAPTURE to the list of known device flags. In show_devices_and_exit() do not print a shorthand number for and in find_interface_by_number() do not count no-capture devices. Update description of the "-D" flag in the man page. $ tcpdump -D 1.enp3s0 [Up, Running, Connected] 2.any (Pseudo-device that captures on all interfaces) [Up, Running, NoInject] 3.lo [Up, Running, Loopback] 4.dag0 (alias for dag0:0) [NoInject] 5.dag0:0 (Rx stream 0) [NoInject] dag0:1 (Tx stream 1) [NoCapture] 6.dag16 (alias for dag16:0) [NoInject] 7.dag16:0 (Rx stream 0) [NoInject] 8.dag17 (alias for dag17:0) [NoInject] 9.dag17:0 (Rx stream 0) [NoInject] 10.nflog (Linux netfilter log (NFLOG) interface) [NoInject] 11.nfqueue (Linux netfilter queue (NFQUEUE) interface) [NoInject]
