As far as I know, now that Itania are no longer being manufactured and shipped, and given that HPE haven't, as far as I 
know, shown any sign of plans to port HP-UX to x86-64, the future is something like "no more HP-UX, just the ability to 
run HP-UX Itanium binaries on x86-64 Linux with binary-to-binary translation and either HP-UX system call emulation or 
HP-UX shared library call emulation".

I can't find much to indicate the details of the strategy, except that it involves "Linux containers" in some fashion; 
if one of those particular "Linux containers" won't run native Linux/x86-64 applications and emulated HP-UX/Itanium 
apps in parallel, maybe there'd be some demand for the HP-UX tcpdump running in a container; otherwise, running a Linux 
tcpdump using Linux libpcap would probably be the future.
