2003-09-07Support string dissector tables in the Tethereal "decode as" stuff.Guy Harris1-11/+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
2003-09-06From Graham Bloice, with changes from me: list the interface index inGuy Harris1-3/+58
"-D" output, and support interface indices as arguments to "-i", tcpdump-style. svn path=/trunk/; revision=8402
2003-09-03And for Cal,Ronnie Sahlberg1-1/+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
2003-08-07From Michael Lum: add the ability to have a preferences file containingGuy Harris1-9/+46
a list of disabled protocols, and to save that list from the Edit > Protocols dialog box. Add checks for read errors in "read_prefs()". Clean up white space. svn path=/trunk/; revision=8144
2003-07-25Fix signed/unsigned comparison warnings.Gilbert Ramirez1-4/+6
svn path=/trunk/; revision=8084
2003-06-30From Lionel Ains:Guy Harris1-69/+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
2003-06-22Ringbuffer rework.Laurent Deniel1-8/+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
2003-06-13Make it compile without libpcap.Guy Harris1-2/+10
svn path=/trunk/; revision=7870
2003-06-05From Lionel Ains: "-d" flag for decode-as support in Tethereal.Guy Harris1-12/+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
2003-05-16Squelch some compiler complaints.Guy Harris1-2/+2
svn path=/trunk/; revision=7682
2003-05-15Implement a ring buffer switch duration:Laurent Deniel1-5/+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
2003-05-14A correct programming practice is to save errno and restore its valueLaurent Deniel1-1/+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
2003-05-04Add support for asynchronous DNS updates using the GNU ADNS library.Gerald Combs1-1/+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
2003-04-23Allow taps to have menu item registration routines; the menu itemGuy Harris1-2/+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
2003-04-16Pull the stuff done in "dissect_packet()" to initialize a column_infoGuy Harris1-2/+2
structure into its own routine; rename "col_init()" to "col_setup()", and call the new routine "col_init()". svn path=/trunk/; revision=7467
2003-04-16Add the notion of a "fence" to columns. A dissector can set the fenceGuy Harris1-2/+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
2003-03-12Change the version messages to put the "compiled with" stuff on aGuy Harris1-8/+12
separate line, and to put the "running with" info on a separate line from that, to make the output narrower. svn path=/trunk/; revision=7344
2003-03-08Put the code to get version numbers of various libraries with whichGuy Harris1-70/+2
Ethereal/Tethereal was linked into a common routine, and use that in both Ethereal and Tethereal. Add to that routine code to get OS version information. svn path=/trunk/; revision=7320
2003-01-01Re-word-wrap the "you can't capture on PPP/WAN interfaces on NT"Guy Harris1-3/+3
message, to make the margins more even and to bring the second line under 80 characters. (It's amazing how long Herman Hollerith's legacy has lasted....) svn path=/trunk/; revision=6835

svn path=/trunk/; revision=6833
2002-12-31Clean up the comments a bit.Guy Harris1-39/+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
2002-12-29From rmkml: support for capturing from a pipe in Tethereal.Guy Harris1-20/+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
2002-12-02Don't cast away constness, and fix variable and structure memberGuy Harris1-3/+3
qualifiers as necessary to ensure that we don't have to. "strcmp()", "strcasecmp()", and "memcmp()" don't return booleans; don't test their results as if they did. Use "guint8", not "guchar", for a pointer to (one or more) 8-bit bytes. Update Michael Tuexen's e-mail address. svn path=/trunk/; revision=6726
2002-11-10Add tethereal's tap objects to Makefile.nmake's "clean" target.Gerald Combs1-19/+1

2002-10-31From Ronnie Sahlberg: have a registration interface for tap listeners,Guy Harris1-61/+35
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

2002-10-24Don't include the header file to get the SNMP version unless we'reGuy Harris1-1/+11
building with an SNMP library. If we have Net-SNMP, include <net-snmp/version.h>, not <ucd-snmp/version.h>. 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()". Supply the include directories for Net-SNMP in the Makefile.nmake for GTK 1.2 and GTK 2. svn path=/trunk/; revision=6493
2002-10-23From Wes Hardaker:Guy Harris1-7/+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

2002-10-17From Ronnie Sahlberg: don't have the tap code do a dissection, leaveGuy Harris1-3/+3

2002-10-09Link to libsnmp under Win32.Gerald Combs1-3/+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
2002-09-27Update tethereal to put the filter string in the statistics table for RPC_STAT.Ronnie Sahlberg1-3/+3
Update gtk and gtk2 versions of RPC_STAT to allow a filter string to be specified on both the command line as well as the GUI. Update the documentation for ethereal to reflect this. svn path=/trunk/; revision=6343
2002-09-26Updated RPCSTAT for tethereal. The command now takes a filter string as an ↵Ronnie Sahlberg1-4/+9

One example extension is rpcstat. Try -Z rpc,rtt,100003,3 as argument to tethereal when reading a capture containing NFSv3 packets. tap-rpcstat.[ch] is intended to demonstrate the api and can be used to base other extensions on. svn path=/trunk/; revision=6175

2002-07-17Get rid of some "unused variable" and "unused static function" warnings,Guy Harris1-4/+18
and some compile errors in Tethereal, when compiling without libpcap. 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
2002-07-16From Graeme Hewson:Guy Harris1-74/+131
Allow "-" as the output file name in Wiretap, referring to the standard error. Optimize the capture loop. Fix some of the error-message printing code in Ethereal and Tethereal. Have Wiretap check whether it can seek on a file descriptor, and pass the results of that test to the file-type-specific "open for output" routine. Have the "open for output" routines for files where we need to seek when writing the file return an error if seeks don't work. svn path=/trunk/; revision=5884

2002-06-30From Graeme Hewson:Guy Harris1-13/+43
pass a non-zero count to "pcap_dispatch()" when possible; fix the check after "test_for_fifo()"; if there's a maximum file size, we're definitely saving to a file, so don't bother checking "ld.pdh", as it won't be null; if writing to a FIFO, flush after "pcap_dispatch()" returns, rather than after every packet, so we don't do as many writes to the FIFO. svn path=/trunk/; revision=5805
2002-06-28SIGINT is, at least as I read some Microsoft documentation, notGuy Harris1-6/+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
