* From Matthijs Melchior: check whether the ring buffer timeout hasGuy Harris2003-09-251-11/+23
| | | | | | | | | | | expired *before* writing a packet, rather than *after* writing a packet, so that if you get no packets for a sufficiently long period that the timeout expires before you get a new packet, the new packet is in the beginning of a new file (as you might get more packets right after that, and want them to be in the new file, rather than have the first packet at the end of one file and the rest of the packets in another file). svn path=/trunk/; revision=8536

* When saving packets, we have a "Save only marked packets" option; labelGuy Harris2003-09-101-2/+2
| | | | | | | | the option to print only marked packets similarly, rather than as "Suppress unmarked packets" (for consistency, and because the latter isn't unlike a double negative). svn path=/trunk/; revision=8451

Supply for the Linux "any" device the same description that libpcap's "pcap_findalldevs()" returns. svn path=/trunk/; revision=8440
* Support string dissector tables in the Tethereal "decode as" stuff.Guy Harris2003-09-071-11/+34
| | | | | | | | | Make the Ethereal "decode as" stuff not blow up with string dissector tables. Selectors for uint dissector tables are unsigned, not signed. svn path=/trunk/; revision=8408
* From Graham Bloice, with changes from me: list the interface index inGuy Harris2003-09-061-3/+58

* And for Cal,Ronnie Sahlberg2003-09-031-1/+4
| | | | | | | | | | Ethereal presents a column to display culmulative bytes into the capture. A new column type is added : Culmulative Bytes. While PacketLength column type specifies the number of bytes in the current packet, Culmulative Bytes specifies the culmulative number of bytes from the start of the capture. svn path=/trunk/; revision=8359

* 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
* Pull the stuff done in "dissect_packet()" to initialize a column_infoGuy Harris2003-04-161-2/+2

* 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()".

| | | | | | | | | | | | | | | | | 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. A compiled version of the Net-SNMP library can be found at http://www.ethereal.com/distribution/win32/development/ svn path=/trunk/; revision=6385
