2012-01-04Move stuff that should *only* be known by the lowest-level code thatGuy Harris1-6/+0
deals with the sync pipe - i.e., only by sync_pipe.c and dumpcap.c - into sync_pipe.h. svn path=/trunk/; revision=40366
2010-05-17When dumpcap is run to get an interface list, interface capabilities, orGuy Harris1-2/+4
interface statistics, have its error messages come out as sync-pipe errors, have it send a sync-pipe "success" message on success, and have the callers get that message and display it. svn path=/trunk/; revision=32843
2010-05-13Fetch an indication of whether the interface supports capturing inGuy Harris1-2/+3
monitor mode at the same time that we fetch its list of link-layer types. Support fetching that list in monitor mode, as the list may be different in regular and monitor mode. If the interface supports monitor mode, when printing the list of link-layer types, indicate whether they're fetched in monitor mode or not, as tcpdump 4.1.x does. svn path=/trunk/; revision=32789

svn path=/trunk/; revision=24407
2008-02-16Pull capture_loop.c into dumpcap.c, as dumpcap is the only program thatGuy Harris1-2/+0
does capturing any more. (We will be inserting a call to give up privileges after the pcap_open_live(), which should fix 2273; we're currently only giving up privileges on platforms with libcap.) svn path=/trunk/; revision=24345
2007-10-26For the Wireshark/TShark -> dumpcap signal pipe on Windows, use a namedGerald Combs1-0/+2
pipe instead of stdin. Add an argument (currently the parent PID) back to the "-Z" flag and use it to construct the pipe name. This lets us pass the parent's stdin handle to dumpcap, which lets us capture from stdin on Windows. Add a comment about checking for the parent process. In capture_loop.c, remove the wait_forever argument from cap_pipe_select() since it was always FALSE. Set the timeout under Windows to 250 ms instead of 250000 ms. svn path=/trunk/; revision=23279
2007-08-02Add a "-S" flag to dumpcap, which prints out interface statistics. UseGerald Combs1-0/+13
this in the GUI rather than calling pcap_stats() directly. This gets rid of the last pcap_open_live() call in the GUI code. Update README.packaging. svn path=/trunk/; revision=22443
2007-07-20Remove the "-I" flag from dumpcap, and add a "-M" flag used to specifyGerald Combs1-0/+3
that "-D" and "-L" should produce machine-readable output. Use this to move an indirect get_pcap_linktype() call from the GUI to dumpcap. svn path=/trunk/; revision=22367
2007-06-11One more step in privilege separation.Gerald Combs1-7/+12
Add a capture_interface_list(), which works similar to get_interface_list() except that it forks dumpcap instead of calling the pcap routines directly. Use it in the GUI. Add a "-I" flag to dumpcap, which prints out verbose interface information. Tested under Windows and Linux. svn path=/trunk/; revision=22071

2006-04-03Put the low-level sync routines into a common file so they can be sharedGuy Harris1-53/+0
by dumpcap and Ethereal (so that, on UN*X, the child process can report a detailed "can't exec dumpcap" error). Rename most of the "sync_pipe_XXX_to_parent()" routines, as they're also in Tethereal, which doesn't have a sync pipe. svn path=/trunk/; revision=17789

2006-03-05Pass two strings in capture child messages, so the child can sendGuy Harris1-1/+7
primary and secondary error messages and let the parent worry about how to display them. This means dumpcap doesn't need stub routines for generating the formatting tags for the primary and secondary messages. Have a separate message for capture filter errors, so that the parent can check whether the capture filter looks like a display filter and report the appropriate message. This means that dumpcap doesn't need a stub routine for compiling display filters (a stub routine also means that Ethereal won't do the check for capture filters that look like display filters!). svn path=/trunk/; revision=17465

dumpcap in addition to the things already done now various dumpcap related code cleanup: mainly #include's and capture engine related stuff svn path=/trunk/; revision=17327
2006-02-11the point of no return ...Ulf Lamping1-3/+0
using dumpcap as the capture child for Ethereal. dumpcap is a plain console application now, even for Win32 (so no WinMain, create_console and special piping stuff reguired). The undocumented command line option -Z will switch dumpcap into "child mode", using binary instead of plain text output messages to communicate with a parent Ethereal. Ethereal's main.c no longer needs to distinguish between child mode or not, so some simplifying here. capture_sync.c has to call dumpcap in a "hidden window" mode using CreateProcess instead of spawnvp, otherwise an uggly console window would appear. The handles created by _pipe doesn't seem to be inheritable for this function, using CreatePipe instead. The file capture_loop.c is only needed by dumpcap, removed from Ethereal link objects. Some debugging aid added and other minor cleanup done. svn path=/trunk/; revision=17256
2005-12-04move the complete functionality of the capture info dialog from ↵Ulf Lamping1-0/+19
capture_loop.c to capture_info.c and call it from capture.c (instead of capture_loop.c). This way, the capture child don't need to now any of the packet_counter things (no epan/packet.h and all alike). Currently the capture_info code will always open another wiretap file instance to build it's own counter values. This isn't optimized for now (next step: use data from cf_continue_tail() somehow). svn path=/trunk/; revision=16669

add a new feature to clear the currently captured packets and restart the capture with the previous parameters various code cleanup and minor bugfixes Win32: use millisecond resolution in capture_loop, to smooth screen update a bit (500ms instead of 1000ms) svn path=/trunk/; revision=14059

don't use global cfile at all but only an untpyed handle to call the cf_... functions in file.c move the save_file member from capture_file to capture_opts, as it's only used while capturing and while preparing it svn path=/trunk/; revision=13276
2004-12-29Don't use a global capture_opts in the capturing engine (this isn't a good ↵Ulf Lamping1-1/+2
idea). Do some more "housekeeping" in the capturing part. Hopefully the unspecified forward declaration of capture_options_t in main.h is portable, but buildbot will tell me. This way I need the internals of that struct only at the places I really use it. svn path=/trunk/; revision=12853
2004-10-30code cleanup: split capture_sync from capture.c into it's own file. Ulf Lamping1-0/+76
