What version of HP-UX is this?
What happens if you type the interface name in the "ifconfig" command,
e.g. "ifconfig rfi0" or "ifconfig eth0"?
Do those interfaces show up in the output of the "lanscan" command?
The only interfaces libpcap can use on HP-UX - and, thus, the only
interfaces that programs using libpcap, such as tcpdump and Ethereal,
can use on HP-UX - are those that
1) use DLPI to connect to the networking stack;
2) use the DLPI provider that can be accessed through
"/dev/dlpi";
3) can have the PPA for the DLPI provider found by searching the
list returned by a DL_HP_PPA_REQ DLPI request.
You would have to ask HP whether that is true of any of the interfaces
on which you want to capture.
