I am trying to use tcpdump on a TRU64 4.0F with netRAIN interface, but whitout luck.
ifconfig -a when tcpdump is started on any interface, shows the relevant
interfaceoption is set to PROMISC,COPYALL
tcpdump -i lo0 works fine
tcpdump -i nr0
tcpdump: Using kernel BPF filter
tcpdump: listening on nr0
then nothing happens
tcpdump -i tu0 returns nothing
tcpdump: WARNING: tu0: no IPV4 address assigned
tcpdump: Using kernel BPF filter
tcpdump: listening on tu0
Then nothing happens
tcpdump -i tu1
tcpdump: WARNING: tu1: no IPV4 address assigned
tcpdump: Using kernel BPF filter
tcpdump: listening on nr0
shows NetRAIN test packet.
ifconfig -a shows that the active interface is tu0
tcpdump is version 3.6
Since I am able to catch packets on the local interface and to some extent on tu1, I
think tracing does work, only not on the active interface.
Good ideas is most welcome
Regards,
Bjarne Blichfeldt
