c - Replay Pcap files like data -

-

i want record handshake messages between server , client file , replay them later.

for example, when run s_server command -debug option, output follows:

read 0x9482088 [0x948d518] (2064 bytes => 2064 (0x810)) 0000 - 0b 00 08 0c 00 08 09 00-04 1a 30 82 04 16 30 82   ..........0...0. 0010 - 02 fe a0 03 02 01 02 02-01 02 30 0d 06 09 2a 86   ..........0...*. 0020 - 48 86 f7 0d 01 01 05 05-00 30 81 88 31 0b 30 09   h........0..1.0. 0030 - 06 03 55 04 06 13 02 4e-4c 31 0b 30 09 06 03 55   ..u....nl1.0...u 0040 - 04 08 0c 02 4e 42 31 12-30 10 06 03 55 04 07 0c   ....nb1.0...u... 0050 - 09 41 4d 53 54 45 52 44-41 4d 31 10 30 0e 06 03   .amsterdam1.0... 0060 - 55 04 0a 0c 07 4d 41 49-4e 20 43 41 31 0c 30 0a   u....main ca1.0. 0070 - 06 03 55 04 0b 0c 03 49-43 54 31 17 30 15 06 03   ..u....ict1.0... 0080 - 55 04 03 0c 0e 77 77 77-2e 6d 61 69 6e 63 61 2e   u....www.mainca.

i can record data files. how can extract data (bytes) buffer? there utility in openssl it? or can done in c program?

thank you!

yes. assuming saving log pcap file, tcpreplay want. if you're not saving pcap, can either libpcap or writing file (the format not terribly complicated).

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
