1 - Building ethereal
The Software Porting And Archive Centre for HP-UX, at
- http://hpux.csc.liv.ac.uk/
+ http://hpux.connect.org.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.
+(with mirrors in various countries, listed on the Centre's home page;
+you may want to choose a mirror closer to you) has ported versions, in
+both source and binary form, for Ethereal, as well as for the libpcap,
+GLib, GTK+, and zlib 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
-O"; there's a comment "Add -Dhpux_9 if building under 9.X". It may
also build with GCC.
+They currently have libpcap 0.6.2; libpcap 0.6.2, and later versions,
+include changes to properly open network devices when given the name
+reported by the lanscan and ifconfig commands - earlier versions didn't
+do this correctly. Therefore, we strongly suggest you use libpcap 0.6.2
+or later, not libpcap 0.5.2.
+
2 - Building GTK+/GLib with HP's C compiler
By default, HP's C compiler doesn't support "long long int" to provide
3 - nettl support
nettl is used on HP-UX to trace various streams based subsystems. Ethereal
-can read nettl files containing IP frames (NS_LS_IP subsystem) and LAPB
-frames (SX25L2 subsystem).
-It has been tested with files generated on HP-UX 9.04 and 10.20.
+can read nettl files containing raw IP frames (NS_LS_IP, NS_LS_TCP,
+NS_LS_UDP, NS_LS_ICMP subsystems), all ethernet/tokenring/fddi driver
+level frames (such as BTLAN, BASE100, GELAN, IGELAN subsystems) and LAPB
+frames (SX25L2 subsystem). Use "ioscan -kfClan" to see the driver
+names and compare that to /etc/nettlgen.conf to find the nettl subsystem
+name for your particular release.
+
+It has been tested with files generated on HP-UX 9.04, 10.20, and 11.x.
Use the following commands to generate a trace (cf. nettl(1M)):
-# IP capture. 0x30000000 means PDU in and PDU out :
-nettl -tn 0x30000000 -e NS_LS_IP -f tracefile
+# IP capture:
+nettl -tn pduin pduout -e NS_LS_IP -f tracefile
+# Driver level capture. Replace btlan with the name of your interface:
+nettl -tn pduin pduout -e btlan -f tracefile
# X25 capture. You must specify an interface :
-nettl -tn 0x30000000 -e SX25l2 -d /dev/x25_0 -f tracefile
-# stop capture. subsystem is NS_LS_IP or SX25L2 :
+nettl -tn pduin pduout -e SX25l2 -d /dev/x25_0 -f tracefile
+# stop capture. subsystem is NS_LS_IP, btlan, SX25L2 :
nettl -tf -e subsystem
-One may be able to specify "-tn pduin pduout" rather than
-"-tn 0x30000000"; the nettl man page for HP-UX 10.30 implies that it
-should work.
+You may have to use "-tn 0x30000000" instead of "-tn pduin pduout"
+on old versions of 10.20 and 9.04.
-4 - "libpcap" on HP-UX
+4 - libpcap on HP-UX
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.
+libpcap; binary distributions are, as noted above, available from the
+Software Porting And Archive Centre for HP-UX, as well as source code.
+
+Versions of libpcap prior to 0.6 didn't handle HP-UX as well as 0.6 and
+later versions do. You should install the latest version.
+
+The source code is also available from the official home of libpcap and
+tcpdump, at
+
+ http://www.tcpdump.org/
+
+if you want a version later than the version available from the Software
+Porting And Archive Centre; however, the versions available from
+tcpdump.org might not, for example, include support for building libpcap
+as a shared library.
+
+5 - HP-UX patches to fix packet capture problems
Note that packet-capture programs such as Ethereal/Tethereal or tcpdump
may, on HP-UX, not be able to see packets sent from the machine on which
-they're running. Some articles on Deja.com discussing this are:
+they're running. Make sure you have a recent "LAN Cummulative/DLPI" patch
+installed.
+
+Some articles on groups.google.com discussing this are:
- http://www.deja.com/[ST_rn=ps]/getdoc.xp?AN=558092266
+ http://groups.google.com/groups?selm=82ld3v%2480i%241%40mamenchi.zrz.TU-Berlin.DE

which says:
PHNE_19826, PHNE_20008, PHNE_20735 on the C200 and now I can see the
outbound traffic too. Thanks again.
+(although those patches may not be the ones to install - there may be
+later patches).
+
+And another message to tcpdump-workers@tcpdump.org, from Rick Jones:

+ To: tcpdump-workers@tcpdump.org
+ Subject: Re: [tcpdump-workers] I Can't Capture the Outbound Traffic
+
+ ...
+
+ http://itrc.hp.com/ would be one place to start in a search for the most
+ up-to-date patches for DLPI and the lan driver(s) used on your system (I
+ cannot guess because 9000/800 is too generic - one hs to use the "model"
+ command these days and/or an ioscan command (see manpage) to guess what
+ the drivers (btlan[3456], gelan, etc) might be involved in addition to
+ DLPI.
+
+ Another option is to upgrade to 11i as outbound promiscuous mode support
+ is there in the base OS, no patches required.
+
Another posting:

+ http://groups.google.com/groups?selm=7d6gvn%24b3%241%40ocean.cup.hp.com
indicates that you need to install the optional STREAMS product to do
captures on HP-UX 9.x:
(as per other messages cited here, the ability to see the system's own
outbound traffic did happen).

- 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.
+Rick Jones reports that HP-UX 11i needs no patches for outbound
+promiscuous mode support.
An additional note, from Jost Martin, for HP-UX 10.20:
/sbin/rc2.d/S350hack_ip_stack pointing to this script.
Now all this is done on every reboot.
+According to Rick Jones, the global promiscuous switch also has to be
+turned on for HP-UX 11.00, but not for 11i - and, in fact, the switch
+doesn't even exist on 11i.
+
Here's the "hack_ip_stack" script:

-
-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.
-
-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. (It appeared
-to work in some tests done on HP-UX 10.20 systems.)
-
-Here's the patch (to vanilla libpcap 0.4; it patches "aclocal.m4",
-"configure", 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 patches "pcap-dlpi.c"):
