The Software Porting And Archive Centre for HP-UX, at http://hpux.csc.liv.ac.uk/ (and with mirrors in various countries, listed on the Centre's home page) has ported versions, in both source and binary form, for Ethereal, as well as for the "libpcap", GLib, GTK+, "zlib", and CMU SNMP libraries that it uses. The changes they've made appear largely to be compile option changes; if you've downloaded the source to the latest version of Ethereal (the version on the Centre's site may not necessarily be the latest version), it should be able to compile, perhaps with those changes. They appear to have used HP-UX's "cc" compiler, with the options "-Ae -O"; there's a comment "Add -Dhpux_9 if building under 9.X". It may also build with GCC. If you want to use Ethereal to capture packets, you will have to install "libpcap"; the INSTALL file for "libpcap" has several comments about HP-UX, which you should read if you're going to install and use "libpcap" on HP-UX.

You may need to reference the card's DLPI device directly. We were having trouble getting Ethereal to capture on an HP-UX 10.20 machine here. I found an article on Deja News that says: "To access a particular interface, you would say "tcpdump -i /dev/dlpiN" where N is the PPA of the interface you wish to use. You get the PPA by looking at the output of lanscan. On 10.20, it is the same value as the NMID. On 11.X, it is the Card Instance number." This didn't help in our case, but it might in yours. The full article is at http://x34.deja.com/[ST_rn=ps]/getdoc.xp?AN=549366486 . Another article by the same author mentions that experimental versions of libpcap and tcpdump are available at ftp://ftp.cup.hp.com/dist/networking/tools/ . The article itself is at http://x34.deja.com/[ST_rn=ps]/getdoc.xp?AN=558665378 . The first of those articles also says: BTW, before you have to make a follow-up post, you will find that unless you have the latest lan common/DLPI/driver patches installed, you will _not_ see the system's own outbound traffic. It appears that a consequence of the fact that HP-UX's DLPI doesn't work like Solaris's, in that, on Solaris, to get at the device "hme0", say, "libpcap" has to open "/dev/hme" and then tell it to use the 0th interface, whilst on HP-UX you have to go through "/dev/dlpi", you won't get a list of interfaces in the dialog box for "Capture:Start" - you'll have to do through the aforementioned song and dance to find the PPA of the interface you want to use, and supply the "dlpiN" name by hand (I think you can omit the "/dev/" in both tcpdump and Ethereal). Here is a patch to "pcap-dlpi.c" in libpcap that, at least on HP-UX 11.X, allows the name of the network interface, rather than the "dlpiN" name, to be specified to tcpdump and Ethereal. It has not been tried on HP-UX 10.20; it fixes one bug that could have caused the code in vanilla libpcap not to correctly find the PPA for an interface on HP-UX 10.20, but HP-UX 10.20's DLPI doesn't supply, in the data returned by a DL_HP_PPA_REQ request, network interface names, so, on systems without the network interface names in that data, the code continues to check the major device number. On HP-UX 11.00, the patch allows a network interface to be specified by name as an argument to tcpdump, rather than requiring that you specify a "dlpiN" name (and it should work equally well with Ethereal). If you try this code on HP-UX 10.20, and it doesn't let you specify the interface by name, please send mail to ethereal-dev@zing.org, so that we know that it didn't work - we'll probably send you debugging patches in the hopes of being able to make it work on 10.20 as well. Here's the patch (to vanilla libpcap 0.4; it patches "configure", "aclocal.m4", and "configure.in", to make the configure script check whether your version of HP-UX supplies the interface names in the reply to a DL_HP_PPA_REQ request, and "pcap-dlpi.c"): *** ../libpcap-0.4/configure Sat Jul 25 12:41:51 1998 --- configure Fri Jan 14 00:40:04 2000 *************** *** 1702,1709 **** fi echo $ac_n "checking if unaligned accesses fail""... $ac_c" 1>&6 !
