On Digital Unix 4.0E, this works fine for me with tcpdump 3.4/libpcap 0.4. By default interfaces are not set to capture traffic "sent/received by the kernel-resident protocol software [for example, IP, ARP, DECnet, LAT] on this host" (from pfconfig manpage). Are you sure to have set "copy-all" mode of your loopback interface via the pfconfig +copyall lo0 command ? Simon - This is the TCPDUMP workers list.
