John, Thanks for the quick response. > Not sure what Netscalar does, but it all should act the same.

After running a tcpdump capture on the interface and analyzing it with Wireshark, I do not see any 3-way handshakes for this particular web application. For any HTTP GET that I see in Wireshark that pertains to this application, when I "Follow TCP Stream", the first entry in Wireshark is always the GET message itself. For all other applications on the network, doing the above results in the first entry being the SYN. I've generated a few dumps with the same results. I wonder if the load balancer is somehow keeping a session active for very long periods (if this even makes sense). If you have any suggestions or thoughts, I'd be very interested.

[Bro] Segmentation fault with dns-anonymizer

by Lothar Braun

Hi, I'm trying to anonymize a DNS trace while running bro 1.5.1 and get a segmentation fault while running bro -r trace.pcap dns-anonymizer.bro -w output.pcap The segmentation fault results in this back trace: #0 0x000000000064c474 in __ns_name_pack () #1 0x000000000064cd32 in __ns_name_compress () #2 0x00000000005d5ae8 in DNS_Rewriter::DnsCopyQuery (this=0x2830fb0, query=0x2834c40, qtype=6, qclass=1) at DNS_Rewriter.cc:100 #3 0x000000000045e713 in bro_rewrite_dns_reply_question (frame=0x2825f20, BiF_ARGS=0x2832440) at dns-rw.bif:23 #4 0x00000000004daaa7 in BuiltinFunc::Call (this=0x22c0050, args=0x2832440, parent=0x2825f20) at Func.cc:451 #5 0x00000000004a5081 in CallExpr::Eval (this=0x276e6d0, f=0x2825f20) at Expr.cc:4629 #6 0x000000000058618f in ExprStmt::Exec (this=0x276e770, f=0x2825f20, flow=@0x7fff72d90aa4) at Stmt.cc:397 #7 0x000000000058723a in StmtList::Exec (this=0x276dba0, f=0x2825f20, flow=@0x7fff72d90aa4) at Stmt.cc:1432 #8 0x00000000004e1ea0 in BroFunc::Call (this=0x2645ee0, args=0x282fec0, parent=0x0) at Func.cc:308 #9 0x0000000000485a0d in EventHandler::Call (this=0x2123a40, vl=0x282fec0, no_remote=false) at EventHandler.cc:67 #10 0x000000000040c835 in Event::Dispatch (this=0x2833810, no_remote=false) at Event.h:43 #11 0x0000000000485439 in EventMgr::Dispatch (this=0x95b760) at Event.cc:107 #12 0x00000000004854a6 in EventMgr::Drain (this=0x95b760) at Event.cc:119 #13 0x000000000051aa68 in net_packet_dispatch (t=1275291343.0222969, hdr=0x22c1fe0, pkt=0x276e812 "", hdr_size=14, src_ps=0x22c1fa0, pkt_elem=0x0) at Net.cc:436 #14 0x000000000051acb5 in net_packet_arrival (t=1275291343.0222969, hdr=0x22c1fe0, pkt=0x276e812 "", hdr_size=14, src_ps=0x22c1fa0) at Net.cc:498 #15 0x000000000052e198 in PktSrc::Process (this=0x22c1fa0) at PktSrc.cc:199 #16 0x000000000051adf1 in net_run () at Net.cc:528 #17 0x000000000040a4df in main (argc=6, argv=0x7fff72d915c8) at main.cc:999 The crash happens within dn_comp in len = dn_comp(dname, pkt + pkt_size, DNS_PKT_SIZE - pkt_size, dn_ptrs, last_dn_ptr); at some point within the trace. This does not happen on the first DNS packet in the trace, but somewhere in the middle. Hence, there where successful calls to DNS_Rewriter::DnsCopyQuery() before the segmentation fault. I tried to debug the issue and found that the crash is probably due to uninitialized variables dn_ptrs and last_dn_ptr. Digging deeper into the problem, I found that the DNS_Rewriter object (this = 0x2830fb0) has never been initialized (the constructor of that object has never been called). Is this a known problem? I could not find any issue at the bug tracker that seems to be related. Can someone give me a hint on how to further debug the problem? Best regards, Lothar

[Bro] Questions on regular expression syntax in BRO system

by tianxin＠mail.ustc.edu.cn

Hello: I am from a research group interested in NIDS, our group has developed several ways to improve regex engine performance and decides to do experiments based on real open-source NIDS system. However, it takes too much time to read bro code and find what we need, so here we need your help . We will appreciate if anyone can answer our questions. The Question: 1 We know that bro uses regular expression, but we didn't find anything about the syntax of the regular expression applied. We want to know where to obtain related information. (As far as we know ,the snort system uses pcre regex engine whose syntax is perl compatible, how about bro? ) 2 Does bro implement a regex engine itself? Or does it use some regex engine library? If it implements an engine, then which part of code is it? If it uses a library, then could you tell me what library it uses?

[Bro] problem installing bro ids

by squald squald

Hi, I'm an university student that is doing a research project on bro, however I'm having some difficulties installing bro by using cygwin. So, I'm wondering if it is possible to install bro onto a windows computer, if yes, please explain the instructions; if no, well I just wanted clarification so I don't continually try. Also if it is possible to install using cygwin, the main problem i have is the use of the pcap library and how to use it correctly since windows uses winpcap. I hope you can clarify some of these issues I'm having. thanks, Kenneth _________________________________________________________________ 30 days of prizes: Hotmail makes your day easier!

[Bro] Bro Installation Problem - Python/GCC

Hi, I've installed Bro 1.5.1 on a Ubuntu 9.04 machine and its working fine however when I try to install the same version on RHEL 5 machine I'm getting errors during compile.

aux/broccoli/bindings/python Note that I didn't have any trouble in configure and it found everything it needed [with shipped pcap switch] I tried searching the mailing list and other resources but couldn't find anything about this or a similar error. I'll greatly appreciate if you could help me in this matter as I'm stuck on this for several days. Do tell me if you need anything else or a complete output for configure/make Thank you for your time :) Faisal iqbal P.S. python version 2.6.1 gcc/g++ version 4.1.2
