2001-11-21Remove the global packet_info called "pi". Dissectors now onlyGilbert Ramirez1-3/+2
access their own "pinfo". A packet_info is stored in epan_dissect_t, which is created for the dissection of a single packet. GUI functions which need to access the packet_info of the currently selected packet used to use "pi"; now they use cfile.edt->pi. cfile's "edt" member is the epan_dissect_t of the currently-selected packet. The functionality of blank_packetinfo() was moved into dissect_packet(), as that's the only place that called blank_packetinfo(), after a spurious call to blank_packetinfo() was removed from packet_list_select_cb(). svn path=/trunk/; revision=4246

2001-11-09Wrap calls to "pcap_datalink()" in a routine that attempts to compensateGuy Harris1-2/+6
for AIX 5.x's non-standard libpcap, where "pcap_datalink()" doesn't return DLT_ values, it returns RFC 1573 ifType values. Put that wrapper, and the routine to get the interface list, in a separate file, for packet-capture utility routines, so not everybody who includes "util.h" needs to include <pcap.h>. Fix up the Wiretap hack for dealing with said incompatibility to use the correct ifType value for Token Ring. svn path=/trunk/; revision=4184
2001-11-04Allow a dissector to register preferences that it no longer supports asGuy Harris1-1/+2
obsolete; we silently ignore attempts to set those in a preferences file, so that we don't spam the user with error messages caused by them having saved preferences in an earlier release that contained those preferences. Make the Diameter and iSCSI dissectors register obsolete preferences. Crash if some code tries to register a preferences module with a name that contains something other than lower-case ASCII letters, numbers, or underscores, or that has already been registered, or if some code tries to register a preference with a name that contains something other than lower-case ASCII letters, numbers, underscores, or periods, or that has already been registered, so that we don't put code like that in a release and have to shovel code into "prefs.c" to fix it up later. (The problem with multiple modules or preferences with the same name should be obvious; the problem with names with blanks, or upper-case letters, or punctuation, is that they're a pain to type on the command line.) svn path=/trunk/; revision=4148
2001-10-26Fix the rest of the signed/unsigned comparison warnings.Gilbert Ramirez1-3/+3
svn path=/trunk/; revision=4088
2001-10-25Handle "pcap_open_live()" succeeding but returning a warning; print theGuy Harris1-9/+20
warning before the capture starts. svn path=/trunk/; revision=4074
2001-10-22Add a routine to get the directory in which personal configuration filesGuy Harris1-2/+3
reside. Use it, rather than concatenating the user's home directory and ".ethereal" in a number of files. Fix up some additional places to use G_DIR_SEPARATOR_S as the pathname separator. svn path=/trunk/; revision=4061
2001-10-04Use longs as file offsets, so that on platforms with 64-bit "long" weGuy Harris1-8/+8
can handle capture files bigger than 2GB. svn path=/trunk/; revision=3993
2001-09-05Close the file to which we're writing before exiting, so that:Guy Harris1-1/+11
buffered data is written out to the file; headers are written if the capture file header depends on the number or sizes of the packets; etc.. svn path=/trunk/; revision=3909
2001-07-27Fix AC_ETHEREAL_PCAP_CHECK so that, if a directory was specified withGuy Harris1-12/+10
"--with-pcap", it adds the "include" subdirectory of that directory to the list of directories to search for include files, rather than adding the directory itself. Check whether libpcap defines "pcap_version", and define HAVE_PCAP_VERSION if it does. Use "pcap_version" iff HAVE_PCAP_VERSION is defined, rather than special-casing MacOS X. Don't #define a string for the WinPcap version; just leave HAVE_PCAP_VERSION undefined on Windows, as WinPcap 2.2beta is out, so we can no longer assume that the Windows version of Ethereal is using WinPcap 2.1. svn path=/trunk/; revision=3792
2001-07-26MacOS support changes, from Michael Tuexen (with some modifications):Guy Harris1-1/+5
replace "--with-plugindir" with "--with-plugins", and have the plugin directory optional - this allows plugins to be disabled; add "--traditional-cpp" on MacOS X/Darwin (Apple's "cc" compiler requires it, for some annoying reason, even though it is, as far as I know, GCC-based, and other GCC's don't require it); on MacOS X, don't use "pcap_version[]", as, for some annoying reason, libpcap on MacOS X doesn't define it. Clean up some whitespace in the help messages for the configure script. Move the AM_CONDITIONAL for SETUID_INSTALL after the point at which "enable_setuid_install" is set, as it tests "enable_setuid_install". svn path=/trunk/; revision=3788
2001-07-17Added a "Suppress Unmarked" option to the print dialog toEd Warnicke1-1/+2
allow you to suppress the printing of unmarked packets. This allows a user to mark the packets they wish to print and print ONLY those packets by suppressing all other unmarked packets. This may seem like a bit of a convoluted way of expressing things, as usually the desired behavior would be to print the marked packets. However, we do NOT print marked packets that are not displayed under the current filter. To be maximally explicite I've expressed this as suppressing unmarked frames. svn path=/trunk/; revision=3736
2001-07-05"open_cap_file()" in Ethereal and Tethereal don't use the FILE_T theyGuy Harris1-3/+5
get from calling "wtap_file()", so get rid of the call and the (otherwise unused) variable to which its result gets assigned. That lets us get rid of "wtap_file()" in Wiretap. It also lets us get rid of the include of "zlib.h" in "file.h"; the #defines of "file_open()", "filed_open()", and "file_close()" are also unnecessary, so we get rid of those as well. However, that means we need to include <zlib.h> in "gtk/main.c" and "tethereal.c", so that the version number of libz is defined and can show up in the version string. svn path=/trunk/; revision=3652
2001-06-08When printing the contents of a raw-data field, don't use the raw dataGuy Harris1-2/+2
of the current frame as the source, use the raw data of the tvbuff that's the data source of that field. svn path=/trunk/; revision=3531
2001-06-08Move the fragment reassembly code into "reassemble.c" andGuy Harris1-1/+14
"reassemble.h", and remove IPv4 dependencies from it. Use it for OSI CLNP segment reassembly as well. svn path=/trunk/; revision=3525
2001-06-05Enable "Match Selected" only if there's a field selected *and* we can doGuy Harris1-3/+2
a "Match Selected" on it - we can't do a "Match Selected" if the field has no value (e.g., FT_NULL) and has a length of 0. If we unselect the current packet, we don't have a protocol tree, so we don't have a currently selected field - clear the "Match Selected" menu item and the display in the status line of information about the currently selected field. Move the low-level statusbar manipulation into "gtk/main.c", in routines whose API doesn't expose anything GTK+-ish. "close_cap_file()" calls one of those routines to clear out the status bar, so it doesn't need to take a pointer to the statusbar widget as an argument. "clear_tree_and_hex_views()" is purely a display-manipulating routine; move it to "gtk/proto_draw.c". Extract from "tree_view_unselect_row_cb()" an "unselect_field()" routine to do all the work that needs to be done if the currently selected protocol tree row is unselected, and call it if the currently selected packet list row is unselected (if it's unselected, there *is* no protocol tree, so no row can be selected), as well as from "tree_view_unselect_row_cb()". Before pushing a new field-description message onto the statusbar, pop the old one off. Get rid of an unused variable (set, but not used). svn path=/trunk/; revision=3513
2001-05-31Support for "-N" flag enabling selected forms of name resolution, fromGuy Harris1-12/+23
Joerg Meyer. Support for saving to the preferences file the settings for all types of name resolution. Do a case-insensitive check for "true" and "false" in Boolean preference settings. svn path=/trunk/; revision=3489
2001-04-20In ANSI C (and in pre-ANSI UNIX implementations), if you return fromGuy Harris1-3/+2
"main()", the program exits, and exits with an exit status equal to the return value of "main()", so "return 0;" is sufficient at the end of "main()". svn path=/trunk/; revision=3350
2001-04-20Add a "return 0;" at the end of main() to pacify MSVC 5 (and probablyGilbert Ramirez1-1/+2
other compilers, too.) svn path=/trunk/; revision=3347
2001-04-18Check the validity of numbers specified in command-line options.Guy Harris1-3/+29
svn path=/trunk/; revision=3326
2001-04-15There's no "enable name resolution in captures" preference in Ethereal,Guy Harris1-2/+2
and never was - there's only an Ethereal-wide "enable name resolution" preference. Name it just "name_resolve". Replace all tests of "g_resolving_actif" with tests of "prefs.name_resolv", and replace all code that sets "g_resolving_actif" with code that sets "prefs.name_resolv", so that the setting of "prefs.name_resolv" actually affects whether names are resolved or not. svn path=/trunk/; revision=3300
2001-04-11The Software Porting And Archive Centre for HP-UX now has libpcap 0.6.2Guy Harris1-12/+9
binaries, so users only need to make sure they have that version installed in order to have Ethereal (and tcpdump, and snort, and so on) accept "lanN"-style names (i.e., names of the sort reported by lanscan and handled by ifconfig), rather than "dlpiN". Get rid of the patches to update libpcap, get rid of the discussion in "README.hpux" of patching libpcap and just say "get 0.6.2", and make the notes on HP-UX kernel patches to fix problems with capturing outgoing packets a separate item in the list of items in "README.hpux". Also update the error messages Ethereal and Tethereal display if they can't open a device and the error is "can't find PPA for XXX" to say "get 0.6.2" rather than "patch libpcap and recompile. svn path=/trunk/; revision=3288
2001-04-07Don't hand "fdata" to "clear_fdata()" if you haven't filled it in.Guy Harris1-2/+3
svn path=/trunk/; revision=3266
2001-04-05Win32 build fix, show "0.5.2 (WinPcap 2.1)" as the libpcap versionGilbert Ramirez1-2/+2
for Win32, and show a slightly more informative (i.e., geared to the user) help message when trying to capture without having WinPcap installed. svn path=/trunk/; revision=3261
2001-04-03Try to load WinPcap only on Windows.Guy Harris1-1/+3
svn path=/trunk/; revision=3251
2001-04-03Now that WinPcap is a DLL, I can load it at run-time rather than load-time.Gilbert Ramirez1-1/+16
That means that I no longer need to distribute capture and non-capture versions of Ethereal for Win32; one version (compiled with WinPcap headers) can run on systems with or without WinPcap. For systems that don't have WinPcap, instead of disabling the Capture menu, Capture|Start brings up a dialogue informing the user that wpcap.dll was not loadable, and gives a URL to the WinPcap home page. svn path=/trunk/; revision=3249
2001-04-02Added two new arguments to epan_init() and proto_init() toEd Warnicke1-2/+3
allow the passing of register_all_protocols() and register_all_protocol_handoffs() through epan_init() to proto_init(). This allows the removal of the compile time dependence of proto.c on register.h. Modified dftest.c, tethereal.c, and gtk/main.c to use the new style epan_init() and depend on register.h. svn path=/trunk/; revision=3237
2001-03-27Make "comp_info_str" static in Ethereal - there's no need for it outsideGuy Harris1-21/+32
"gtk/main.c" in Ethereal. Add the GLib version to it in Ethereal, and put in the GLib version rather than the GTK+ version in Tethereal (which isn't linked with GTK+...). Make it a GString; this makes the code to construct it slightly less ugly, especially now that we're putting the GLib version in. Fix the code for the "-D" flag in Tethereal to compile in a no-libpcap version (in a no-libpcap version, it just says that this version of Tethereal wasn't compiled with capture support). svn path=/trunk/; revision=3196
2001-03-27Give Tethereal a "-D" flag, inspired by WinPcap's "-D" flag, whichGuy Harris1-3/+25
prints a list of all network interfaces it found on which it can capture (the same list as the one that shows up in the "Interface" combo box in Ethereal's "Capture Preferences" dialog). svn path=/trunk/; revision=3194
2001-03-24Clear "fdata->data_src" when initializing a "frame_data" structure.Guy Harris1-1/+15
When we're done with a "frame_data" structure, free all data attached to it. svn path=/trunk/; revision=3182
2001-03-23Added named data sources printing support, written by Guy HarrisJeff Foster1-3/+2
svn path=/trunk/; revision=3167
2001-02-18In the MSVC++ 6.0 C library, "line-buffered" doesn't mean what one mightGuy Harris1-3/+38
expect - it means "same as fully-buffered". This means that the "-l" flag is a no-op on Windows. Instead of setting line-buffered mode with "setvbuf()", set a flag and, if that flag is set, flush the standard output after the information for ever packet is printed; this isn't "line-buffered", either, but, as the reason for doing line-buffering is to allow the output of Tethereal to be piped to a program and to have that program see the output for a packet as soon as the packet is seen and dissected, it should be just as good as line-buffered. svn path=/trunk/; revision=3047
2001-02-11Report failures of "pcap_stats()", as tcpdump does.Guy Harris1-8/+21
Print the "Capturing on <interface>" message, the running count of packets captured, and error messages to the standard error in Tethereal, so that you can pipe the output of a live capture that's printing packets to a program or script without that script having to worry about parsing stuff other than dissected packet summaries or details (tcpdump does the same). svn path=/trunk/; revision=3017
2001-02-11In Ethereal, attempt to get the packet statistics from libpcap whenGuy Harris1-3/+12
capturing; if we succeed, display the packet drops count as the "Drops" value in the status line and as the "Dropped packets" statistics in the summary dialog box, otherwise don't display it at all. In Tethereal, attempt to get the packet statistics from libpcap when capturing; if we succeed, and if there were any dropped packets, print out the count of dropped packets when the capture finishes. svn path=/trunk/; revision=3016
2001-02-10Check for errors when writing a capture file.Guy Harris1-12/+81
Report errors when writing or closing a capture file. Clean up some I/O error messages. svn path=/trunk/; revision=3011
2001-02-01Create a more modular type system for the FT_* types. Put themGilbert Ramirez1-5/+5
into epan/ftypes. Re-write display filter routines using Lemon parser instead of yacc. Besides using a different tool, the new grammar is much simpler, while the display filter engine itself is more powerful and more easily extended. Add dftest executable, to test display filter "bytecode" generation. Add option to "configure" to build dftest or randpkt, both of which are not built by default. Implement Ed Warnicke's ideas about dranges in the new display filter and ftype code. Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree, while FT_PROTOCOL is used for protocols. This was necessary for being able to make byte slices (ranges) out of protocols, like "frame[0:3]" Win32 Makefile.nmake's will be added tonight. svn path=/trunk/; revision=2967
2001-01-29There's no need for a member of a "capture_file" structure holding aGuy Harris1-1/+3
compiled capture filter program, so remove it, and remove the include of <pcap.h> from "file.h"; instead, have local "struct bpf_program" structures where needed, and have those files that need stuff from <pcap.h> include it. This cleans stuff up a bit, and should eliminate a pile of compile warnings with Visual C++ due to <pcap.h> and some GTK+/GLib header file (or files they include) both defining "inline". svn path=/trunk/; revision=2955

svn path=/trunk/; revision=2821
2000-12-03Pull the code to set the fields in the "cfile.cinfo" structure into aGuy Harris1-8/+2
common routine to initialize a "column_info()" structure, shared by Ethereal and Tethereal. svn path=/trunk/; revision=2739

2000-11-20Initialize winsock as we do in Ethereal.Gilbert Ramirez1-1/+11
svn path=/trunk/; revision=2680
2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-10/+13
can be put, and a pointer to the string for the column, which might or might not point to that buffer. Add a routine "col_set_str()", which sets the string for the column to the string passed to it as an argument; it should only be handed a static string (a string constant would be ideal). It doesn't do any copying, so it's faster than "col_add_str()". Make the routines that append to columns check whether the pointer to the string for the column points to the buffer for the column and, if not, copy the string for the column to the buffer for the column so that you can append to it (so you can use "col_set_str()" and then use "col_append_str()" or "col_append_fstr()"). Convert a bunch of "col_add_str()" calls that take a string constant as an argument to "col_set_str()" calls. Convert some "col_add_fstr()" calls that take a string constant as the only argument - i.e., the format string doesn't have any "%" slots into which to put strings for subsequent arguments to "col_set_str()" calls (those calls are just like "col_add_str()" calls). Replace an END_OF_FRAME reference in a tvbuffified dissector with a "tvb_length(tvb)" call. svn path=/trunk/; revision=2670
2000-11-09Move a "putchar('\n')" that caused an extra newline to be printed afterGuy Harris1-2/+2
the protocol tree was printed. svn path=/trunk/; revision=2586
2000-11-06In Tethereal, when printing summary lines, print the fields specified inGuy Harris1-32/+182
the preferences file, don't just print a wired-in list of fields. Always print the time stamp. svn path=/trunk/; revision=2573
2000-11-01Add a fourth choice of time format in the packet list display, whichGuy Harris1-2/+4
shows the date (in YYYY-MM-DD format) as well as the time of day when the packet arrived. svn path=/trunk/; revision=2547
2000-11-01Instead of failing if we can't find a netmask for the interface on whichGuy Harris1-4/+9
we're capturing, just use a netmask of 0, and warn the user in Tethereal (doing it in Ethereal would be more disruptive, and doing so only once per interface in a session is a bit of work, as, in an "Update list of packets in real time" capture the child process would have to tell the parent that it couldn't get the netmask). svn path=/trunk/; revision=2546
2000-10-31Get rid of a statement that should've been deleted when we started usingGuy Harris1-2/+1
"compute_timestamp_diff()" to compute the difference betwen time stamps but that wasn't deleted, causing the time difference between a frame and the previous frame to be computed incorrectly in Tethereal. svn path=/trunk/; revision=2543
2000-10-16Give libethereal its own configuration file, and have that configurationGuy Harris1-2/+2
file, rather than the top-level Ethereal configuration file, check for "inet_aton()", "inet_pton()", and "inet_ntop()". Then make its Makefile.am include the appropriate object files if necessary. Otherwise, they don't get built and put into libethereal, and therefore attempts to link with anything in libethereal that uses them fail on platforms that lack ethem, causing the build to fail. That means a bunch of things need to be fixed to cope with libethereal having its own "config.h" file; this means removing the include of "config.h" from some libethereal header files. Move the definitions of the path names used only by "resolv.c" to "resolv.c" from "resolv.h" (so "resolv.h" doesn't need "config.h", define HAVE_PLUGINS in the configure script (so we don't have to include it in "plugins.h" to check whether HAVE_DLFCN_H is defined). Unfortunately, stuff outside libethereal needs to know PLUGIN_DIR; for now, define that in the top-level configuration file, and have Ethereal and Tethereal pass it as an argument to "epan_init()" - that should be cleaned up at some point. Remove from the top-level configure script checks for things used only in libethereal. svn path=/trunk/; revision=2498
