* From Lionel Ains:Guy Harris2003-06-301-69/+138
| | | | | | | | | | | | | | | | | | | | | | don't assume that a dissector handle has a protocol associated with it (there's none for the "OSI network layer" dissector, for example, as that dissector hands off to one of several protocols based on the NLPID); rename a few functions to have names that better explain what they do; have separate functions to show all the layer types (dissector tables) and to show all the protocols supported for a layer type, and have both of them take, as an argument, the standard I/O stream to which they should write; improve the parser for the "-d" option to give more information on errors; fix up some comments. svn path=/trunk/; revision=7949
* Ringbuffer rework.Laurent Deniel2003-06-221-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | Almost completely rewritten in order to: - be able to use a unlimited number of ringbuffer files 0 specified with -b argument or in the GUI, means that the number of file is unlimited. else the maximum number of ring buffer files is arbitrarily set to 1024. - close the current file and open (truncating it) the next file at switch - set the final file name once open (or reopen) - avoid the deletion of files that could not be truncated (can't arise now) and do not erase empty files The idea behind that is to remove the limitation of the maximum # of ringbuffer files being less than the maximum # of open fd per process and to be able to reduce the amount of virtual memory usage (having only one file open at most) or the amount of file system usage (by truncating the files at switch and not the capture stop, and by closing them which makes possible their move or deletion after a switch). svn path=/trunk/; revision=7912

* From Lionel Ains: "-d" flag for decode-as support in Tethereal.Guy Harris2003-06-051-12/+277
| | | | | | | | | | | | | | | | Add a new routine to iterate through all dissector tables, calling a routine for each table, to support having the "-d" code list all dissector tables. Get rid of "dissector_handle_get_dissector_name()"; it was put in there for "-d", but turns out not to be necessary for that. Clean up the usage message a bit (using the convention, adhered to by at least some UNIX utilities, of listing all the flags with no arguments in a single lump, and then listing the ones with arguments individually, and also putting "-v" and "-h" in a separate lump, as Ethereal does). svn path=/trunk/; revision=7788

* Implement a ring buffer switch duration:Laurent Deniel2003-05-151-5/+79
| | | | | | | | | | | | | | | | | | | when the new "Rotate capture file every n second(s)" checkbox or the -b <# of file>[:<duration>] argument are used, [t]ethereal will skip to the next ring buffer file if the specified duration has elapsed (even if the specified capture size is not reached). This is useful when you want to have separate capture files per hour or day for instance. I let the autostop filesize parameter mandatory (i.e. the "rotate capture file after n kilobytes") but this could be no longer strictly necessary when that new feature is used ... Another point: it might be interesting to really truncate the file at the switch and not the closure ... According to user comments and my own real case tests, I might plan to enhance this point and others (still ring buffer related) in the future. svn path=/trunk/; revision=7678
* A correct programming practice is to save errno and restore its valueLaurent Deniel2003-05-141-1/+3
| | | | | | | | | | | | | | | | | | | | in all signal handlers that could modify it (i.e. by calling system calls or worst standard C library functions). Else the following code for instance is buggy if a signal arises between the tests: if (system_call() == -1) { if (errno == Exxx) { ... } else { ... } } And MANY (open source or not) programs are broken that way ... svn path=/trunk/; revision=7664
* Add support for asynchronous DNS updates using the GNU ADNS library.Gerald Combs2003-05-041-1/+6
| | | | | | | | | | | Support can be enabled at configure time by using "--with-adns=DIR". If support is enabled, async queries happen whenever host name resolution is enabled. Do we need a separate preference for async queries? Currently, only IPv4 reverse queries are supported. I can add IPv4 forward lookup support, but I don't have any way to test IPv6 queries. svn path=/trunk/; revision=7640
* Allow taps to have menu item registration routines; the menu itemGuy Harris2003-04-231-2/+5
| | | | | | | | | | | | | | | | | | | | | registration routines, for taps with menu items (taps that can be run from the "Tools->Statistics" menu), create the menu item for the tap. "make-tapreg-dotc" constructs a "register_all_tap_menus()" function that calls all the tap menu item registration routines it finds, and Ethereal calls that routine after the main window has been constructed (so that the main menu exists, as the menu items are added to it). (Tethereal doesn't call it.) Get rid of the "menu" and "menu_init" arguments to "register_ethereal_tap"; the menu item is registered in the tap's menu item registration routine, not in its main registration routine. Have the RTP GUI tap register its menu item that way, rather than by having it compiled into "gtk/menu.c". (We're not ready yet to have taps whose menu items are under a submenu register themselves in that fashion, as "register_tap_menu_item()" can't yet create submenus.) svn path=/trunk/; revision=7540

* Add the notion of a "fence" to columns. A dissector can set the fenceGuy Harris2003-04-161-2/+2
| | | | | | | | | | to "protect" what's currently in the column, so that attempts to clear the column will only clear stuff after the fence and attempts to overwrite the column will append stuff after the fence. This, for example, allows a dissector to arrange that the Info column contain information for its protocol and for protocols running atop it. svn path=/trunk/; revision=7466

* Clean up the comments a bit.Guy Harris2002-12-311-39/+42
| | | | | | | | | | | | | | | | | | | Use _WIN32 rather than WIN32 throughout (both of them appear to work - I don't know whether one is the "right" one to use and, if one is, which one it is - and they're both used in Ethereal, but let's at least be consistent within a given file). Update the capture device open failure message on Windows not to say Token Ring devices aren't supported - current versions of WinPcap do support it, and the Ethereal message was updated, but the Tethereal one wasn't. Fix up the Tethereal code to match the Ethereal code a bit more, so that we go to "error" on Windows if the capture device open fails, and so that the code actually compiles on Windows. Fix up the indentation while we're at it. svn path=/trunk/; revision=6829
* From rmkml: support for capturing from a pipe in Tethereal.Guy Harris2002-12-291-20/+385
| | | | | | | | | | | | Fix up the documentation of the "-i" flag in the Ethereal man page to note only that "netstat -i" and "ifconfig -a" *might* work, to specifically note that not all UNIXes support the "-a" flag to "ifconfig", and to note that pipe data must be in *standard* libpcap format. Document the support for pipes in the "-i" flag in Tethereal. svn path=/trunk/; revision=6822

| | | | | | | | | | | | | | | | and generate the table of stuff to register from tap source files, so Tethereal doesn't need to know what tap listeners exist. Get rid of "tap-xxx.h" files, as they're now empty. Add "tethereal-tap-register.c" to the .cvsignore file, as it's a new generated file. Update "Makefile.nmake" to generate "tethereal-tap-register.c". Clean up "Makefile.am" and "Makefile.nmake" a bit. svn path=/trunk/; revision=6525

Don't include any of the SNMP headers unless HAVE_SOME_SNMP is defined. Include <net-snmp/config_api.h> if we have Net-SNMP, to declare "read_premib_configs()" and "read_configs()".

* From Wes Hardaker:Guy Harris2002-10-231-7/+17
| | | | | | | | | | | | | | | | | Define HAVE_SOME_SNMP if either HAVE_UCD_SNMP or HAVE_NET_SNMP is defined, and use HAVE_SOME_SNMP, rather than HAVE_UCD_SNMP, in most places when testing whether we have an SNMP library or not. Be more selective when including Net-SNMP header files. Fix up {gtk,gtk2}/main.c to do the same SNMP stuff that tethereal.c does - including the MIB stuff that gtk/main.c was doing but gtk2/main.c wasn't doing. Fix the copyright date in gtk/main.c. svn path=/trunk/; revision=6483

* Link to libsnmp under Win32.Gerald Combs2002-10-091-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | In gtk/main.c and tethereal.c set MIBDIRS to <get_program_path()>\snmp\mibs so that we can drop the MIB files there, instead of the default c:\usr\... path. Add NET_SNMP_DIR to config.nmake and modify Makefile.nmake to adjust CFLAGs, ethereal_LIBS and tethereal_LIBS accordingly. Define HAVE_UCD_SNMP in config.h.win32. I tested this by creating c:\program files\ethereal\snmp\mibs and dropping in the MIB files that come with Net-SNMP. Ethereal resolved system.sysDescr.0 to "iso.3.6.1.2.1.1.1.0" under Windows. Under Linux it resolved to "SNMPv2-MIB::sysDescr.0". Ethereal.nsi still needs to be updated.

If libpcap is missing (whether that's detected at compile time or, as on Windows, at run time), don't call any of the "capture_prefs" routines - the routine to create the capture preferences page wasn't called, so the other routines can try to refer to non-existent widgets and other items and crash. Get rid of the stub routines in "capture_prefs()" used when compiling without libpcap, as they're no longer called. svn path=/trunk/; revision=5888

* SIGINT is, at least as I read some Microsoft documentation, notGuy Harris2002-06-281-6/+44
| | | | | | | | | | | | | | | supported in Win32 applications; use the native Win32 mechanism for catching ^C (and other events that would terminate a program running in a console window). That mechanism (and the signal mechanism in the MSVC++ C run-time) cause the handler to be run in a separate thread, so it can't just do a longjmp. Fortunately, WinPcap's packet-dispatch loop, unlike the libpcap loop on some UNIX platforms, can be interrupted by ^C, so we don't have to do the longjmp there - we can just set "ld.go" to FALSE to terminate the capture loop. svn path=/trunk/; revision=5776
