3 - "libpcap" on HP-UX

1 - Building ethereal

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.

2 - 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.

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
# 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 -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.

3 - "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.

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:

   Two things:
   1. You do need a late "LAN products cumulative patch" (e.g.  PHNE_18173
  for   s700/10.20).
   2. You must use
echo 'lanc_outbound_promisc_flag/W1' | /usr/bin/adb -w /stand/vmunix /dev/kmem
     You can insert this e.g. into /sbin/init.d/lan

  What you are seeing is expected, un-patched, behaviour for an HP-UX
  system.  On 11.00, you need to install the latest lancommon/DLPI
  patches, and then the latest driver patch for the interface(s) in use. 
  At that point, a miracle happens and you should start seeing outbound
  traffic.

[That article also mentions the patch that appears below.]

  Thanks a lot.  I have this problem on several machines running HPUX
  10.20 and 11.00.  The machines where patched up before y2k so did not
  know what to think.  Anyway I have now installed PHNE_19766,
  PHNE_19826, PHNE_20008, PHNE_20735 on the C200 and now I can see the
  outbound traffic too.  Thanks again.

Another posting:

        http://www.deja.com/[ST_rn=ps]/getdoc.xp?AN=457744130

indicates that you need to install the optional STREAMS product to do
captures on HP-UX 9.x:

  I'm reasonably confident that any port of tcpdump to 9.X would require
  the (then optional) STREAMS product.  This would bring DLPI, which is
  what one uses to access interfaces in promiscuous mode.
  
  I'm not sure that HP even sells the 9.X STREAMS product any longer,
  since HP-UX 9.X is off the pricelist (well, maybe 9.10 for the old 68K
  devices). 
  
  Your best bet is to be up on 10.20 or better if that is at all
  possible.  If your hardware is supported by it, I'd go with HP-UX 11. 
  If you want to see the system's own outbound traffic, you'll never get
  that functionality on 9.X, but it might happen at some point for 10.20
  and 11.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.

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"):
