$Id: README.hpux,v 1.12 2000/04/29 08:38:35 guy Exp $ Contents: 1 - Building ethereal 2 - Building GTK+/GLib with HP's C compiler 3 - nettl support 4 - "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 - Building GTK+/GLib with HP's C compiler By default, HP's C compiler doesn't support "long long int" to provide 64-bit integral data types on 32-bit platforms; the "-Ae" flag must be supplied to enable extensions such as that. Ethereal's "configure" script automatically includes that flag if it detects that the native compiler is being used on HP-UX; however, the configure scripts for GTK+ and GLib don't do so, which means that 64-bit integer support won't be enabled. This may prevent some parts of Ethereal from compiling; in order to get 64-bit integer support in GTK+/GLib, edit all the Makefiles for GTK+ and GLib, as generated by the GTK+ and GLib "configure" scripts, to add "-Ae" to all "CFLAGS = " definitions found in those Makefiles. (If a Makefile lacks a "CFLAGS = " definition, there's no need to add a definition that includes "-Ae".) 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. 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. 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. 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.

Search/Read the archives ?-) 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.] and http://www.deja.com/[ST_rn=ps]/getdoc.xp?AN=586494200 which says: Newsgroups: comp.sys.hp.hpux Subject: Re: tcpdump only shows incoming packets Date: 02/16/2000 From: Harald Skotnes Rick Jones wrote: ... > What you are seeing is expected, un-patched, behaviour for an HP-UX > system.

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: Newsgroups: comp.sys.hp.hpux Subject: Re: tcpdump HP/UX 9.x Date: 03/22/1999 From: Rick Jones Dave Barr (barr@cis.ohio-state.edu) wrote: : Has anyone ported tcpdump (or something similar) to 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. rick jones (as per other messages cited here, the ability to see the system's own outbound traffic did happen). Another note, from a mail message to the "ethereal-users" list: Date: Wed, 22 Dec 1999 09:05:47 -0600 (EST) From: Gerald Combs To: Lothar Seitter cc: ethereal-users@zing.org Subject: Re: [ethereal-users] permission problem with capturing On Wed, 22 Dec 1999, Lothar Seitter wrote: > running 'ethereal' under HP-UX 11 with root permission and > /dev/lan0 set to 777, I always get the message: > "There are no network interfaces that can be opened. > Please to make sure you have sufficient permission to > capture packets." > > I start ethereal with 'etheral -i lan0' and lan0 is definitely > the lan interface. > > What am I missing??? 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. An additional note, from Jost Martin, for HP-UX 10.20: Q: How do I get ethereral on HPUX to capture the _outgoing_ packets of an interface A: You need to get PHNE_20892,PHNE_20725 and PHCO_10947 (or newer, this is as of 4.4.00) and its dependencies. Then you can enable the feature as descibed below: Patch Name: PHNE_20892 Patch Description: s700 10.20 PCI 100Base-T cumulative patch To trace the outbound packets, please do the following to turn on a global promiscuous switch before running the promiscuous applications like snoop or tcpdump: adb -w /stand/vmunix /dev/mem lanc_outbound_promisc_flag/W 1 (adb will echo the result showing that the flag has been changed) $quit (Thanks for this part to HP-support, Ratingen) The attached hack does this and some security-related stuff (thanks to hildeb@www.stahl.bau.tu-bs.de (Ralf Hildebrandt) who posted the security-part some time ago) <> (Don't switch IP-forwarding off, if you need it !) Install the hack as /sbin/init.d/hacl_ip_stack (adjust permissions !) and make a sequencing-symlink /sbin/rc2.d/S350hack_ip_stack pointing to this script. Now all this is done on every reboot. Here's the "hack_ip_stack" script: -----------------------------------Cut Here------------------------------------- #!/sbin/sh # # nettune: hack kernel parms for safety OKAY=0 ERROR=-1 # /usr/contrib/bin fuer nettune auf Pfad PATH=/sbin:/usr/sbin:/usr/bin:/usr/contrib/bin export PATH ########## # main # ########## case $1 in start_msg) print "Tune IP-Stack for security" exit $OKAY ;; stop_msg) print "This action is not applicable" exit $OKAY ;; stop) exit $OKAY ;; start) ;; # fall through *) print "USAGE: $0 {start_msg | stop_msg | start | stop}" >&2 exit $ERROR ;; esac ########### # start # ########### # # tcp-Sequence-Numbers nicht mehr inkrementieren sondern random # Syn-Flood-Protection an # ip_forwarding aus # Source-Routing aus # Ausgehende Packets an ethereal/tcpdump etc. /usr/contrib/bin/nettune -s tcp_random_seq 2 || exit $ERROR /usr/contrib/bin/nettune -s hp_syn_protect 1 || exit $ERROR /usr/contrib/bin/nettune -s ip_forwarding 0 || exit $ERROR echo 'ip_block_source_routed/W1' | /usr/bin/adb -w /stand/vmunix /dev/kmem || exit $ERROR echo 'lanc_outbound_promisc_flag/W 1' | adb -w /stand/vmunix /dev/mem || exit $ERROR exit $OKAY -----------------------------------Cut Here------------------------------------- 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"): diff -c ../libpcap-0.4/aclocal.m4 ./aclocal.m4 *** ../libpcap-0.4/aclocal.m4 Fri Jun 12 03:45:15 1998 --- ./aclocal.m4 Tue Jan 4 21:02:13 2000 *************** *** 415,420 **** --- 415,454 ---- fi]) dnl + dnl Checks to see if the dl_hp_ppa_info_t struct has the HP-UX 11.00 + dnl dl_module_id_1 member + dnl + dnl usage: + dnl + dnl AC_LBL_HP_PPA_INFO_T_DL_MODULE_ID_1 + dnl + dnl results: + dnl + dnl HAVE_HP_PPA_INFO_T_DL_MODULE_ID_1 (defined) + dnl + dnl NOTE: any compile failure means we conclude that it doesn't have + dnl that member, so if we don't have DLPI, don't have a + dnl header, or have one that doesn't declare a dl_hp_ppa_info_t type, + dnl we conclude it doesn't have that member (which is OK, as either we + dnl won't be using code that would use that member, or we wouldn't + dnl compile in any case). + dnl + AC_DEFUN(AC_LBL_HP_PPA_INFO_T_DL_MODULE_ID_1, + [AC_MSG_CHECKING(if dl_hp_ppa_info_t struct has dl_module_id_1 member) + AC_CACHE_VAL(ac_cv_lbl_dl_hp_ppa_info_t_has_dl_module_id_1, + AC_TRY_COMPILE([ + # include + # include + # include ], + [u_int i = sizeof(((dl_hp_ppa_info_t *)0)->dl_module_id_1)], + ac_cv_lbl_dl_hp_ppa_info_t_has_dl_module_id_1=yes, + ac_cv_lbl_dl_hp_ppa_info_t_has_dl_module_id_1=no)) + AC_MSG_RESULT($ac_cv_lbl_dl_hp_ppa_info_t_has_dl_module_id_1) + if test $ac_cv_lbl_dl_hp_ppa_info_t_has_dl_module_id_1 = yes ; then + AC_DEFINE(HAVE_HP_PPA_INFO_T_DL_MODULE_ID_1) + fi]) + + dnl dnl Checks to see if -R is used dnl dnl usage: Common subdirectories: ../libpcap-0.4/bpf and ./bpf diff -c ../libpcap-0.4/configure ./configure *** ../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 !
