9 The Software Porting And Archive Centre for HP-UX, at
11 http://hpux.csc.liv.ac.uk/
13 (and with mirrors in various countries, listed on the Centre's home
14 page) has ported versions, in both source and binary form, for Ethereal,
15 as well as for the "libpcap", GLib, GTK+, "zlib", and CMU SNMP libraries
18 The changes they've made appear largely to be compile option changes; if
19 you've downloaded the source to the latest version of Ethereal (the
20 version on the Centre's site may not necessarily be the latest version),
21 it should be able to compile, perhaps with those changes.
23 They appear to have used HP-UX's "cc" compiler, with the options "-Ae
24 -O"; there's a comment "Add -Dhpux_9 if building under 9.X". It may
29 nettl is used on HP-UX to trace various streams based subsystems. Ethereal
30 can read nettl files containing IP frames (NS_LS_IP subsystem) and LAPB
31 frames (SX25L2 subsystem).
32 It has been tested with files generated on HP-UX 9.04 and 10.20.
34 Use the following commands to generate a trace (cf. nettl(1M)):
36 # IP capture. 0x30000000 means PDU in and PDU out :
37 nettl -tn 0x30000000 -e NS_LS_IP -f tracefile
38 # X25 capture. You must specify an interface :
39 nettl -tn 0x30000000 -e SX25l2 -d /dev/x25_0 -f tracefile
40 # stop capture. subsystem is NS_LS_IP or SX25L2 :
41 nettl -tf -e subsystem
43 3 - "libpcap" on HP-UX
45 If you want to use Ethereal to capture packets, you will have to install
46 "libpcap"; the INSTALL file for "libpcap" has several comments about
47 HP-UX, which you should read if you're going to install and use

71 You may need to reference the card's DLPI device directly. We were having
72 trouble getting Ethereal to capture on an HP-UX 10.20 machine here. I
73 found an article on Deja News that says:
75 "To access a particular interface, you would say "tcpdump -i /dev/dlpiN"
76 where N is the PPA of the interface you wish to use. You get the PPA by
77 looking at the output of lanscan. On 10.20, it is the same value as the
78 NMID. On 11.X, it is the Card Instance number."
80 This didn't help in our case, but it might in yours. The full article is
81 at http://x34.deja.com/[ST_rn=ps]/getdoc.xp?AN=549366486 .
83 Another article by the same author mentions that experimental versions of
84 libpcap and tcpdump are available at
85 ftp://ftp.cup.hp.com/dist/networking/tools/ . The article itself is at
86 http://x34.deja.com/[ST_rn=ps]/getdoc.xp?AN=558665378 .
88 The first of those articles also says:
90 BTW, before you have to make a follow-up post, you will find that
91 unless you have the latest lan common/DLPI/driver patches installed,
92 you will _not_ see the system's own outbound traffic.
94 It appears that a consequence of the fact that HP-UX's DLPI doesn't work
95 like Solaris's, in that, on Solaris, to get at the device "hme0", say,
96 "libpcap" has to open "/dev/hme" and then tell it to use the 0th
97 interface, whilst on HP-UX you have to go through "/dev/dlpi", you won't
98 get a list of interfaces in the dialog box for "Capture:Start" - you'll
99 have to do through the aforementioned song and dance to find the PPA of
100 the interface you want to use, and supply the "dlpiN" name by hand (I
101 think you can omit the "/dev/" in both tcpdump and Ethereal).
103 Here is a patch to "pcap-dlpi.c" in libpcap that, at least on HP-UX
104 11.X, allows the name of the network interface, rather than the "dlpiN"
105 name, to be specified to tcpdump and Ethereal. It has not been tried on
106 HP-UX 10.20; it fixes one bug that could have caused the code in vanilla
107 libpcap not to correctly find the PPA for an interface on HP-UX 10.20,
108 but HP-UX 10.20's DLPI doesn't supply, in the data returned by a
109 DL_HP_PPA_REQ request, network interface names, so, on systems without
110 the network interface names in that data, the code continues to check
111 the major device number.
113 On HP-UX 11.00, the patch allows a network interface to be specified by
114 name as an argument to tcpdump, rather than requiring that you specify a
115 "dlpiN" name (and it should work equally well with Ethereal).
117 If you try this code on HP-UX 10.20, and it doesn't let you specify the
118 interface by name, please send mail to ethereal-dev@zing.org, so that we
119 know that it didn't work - we'll probably send you debugging patches in
120 the hopes of being able to make it work on 10.20 as well.
122 Here's the patch (to vanilla libpcap 0.4; it patches "configure",
123 "aclocal.m4", and "configure.in", to make the configure script check
124 whether your version of HP-UX supplies the interface names in the reply
125 to a DL_HP_PPA_REQ request, and "pcap-dlpi.c"):
