similar to: Can not debug sshd in gdb

I'm trying to troubleshoot gssapi_with_mic authentication with OpenSSH 5.2p1 on FreeBSD 8.0. If I run sshd with maximum debug "sshd -ddd" the most detail I get is: GSSAPI MIC check failed That comes from line 282 in auth2-gss.c 279 if (!GSS_ERROR(PRIVSEP(ssh_gssapi_checkmic(gssctxt, &gssbuf, &mic)))) 280 authenticated =

I am trying to do some analysis and modification on the cipher text in per packet increments. Having a bit of trouble getting the cipher text per packet. I believe I am getting the correct sent cipher text (from inside packet_send2 - compared it to a packet capture to be sure) but not certain about getting the recieving stream of cipher text. I have, of coarse, determined that packet_read_poll2

I'm trying to follow the example in the R for Windows FAQ on running gdb and am getting stuck because gdb tells me "Cannot access memory at address ...". Here's what my gdb session looks like (This one from a cygwin shell, but same results from plain Windows CMD shell): $ cd R-devel/src/gnuwin32 $ gdb ../../bin/Rgui.exe GNU gdb 5.2.1 Copyright 2002 Free Software Foundation,

Hi, I am trying to debug my llvm pass called -aa-eval-garg11 using gdb. However I am not able to establish a breakpoint in any function of my pass. I have compiled my pass with a debug build and I have also compiled the input file (using llvm-gcc) with the -g flag. Given below is the exact output.

Hi John, Yes, it was the problem of the namespace. Sorry for bugging for such a silly mistake.

Since FreeBSD is an ELF target, this should work fine. I've also tested that this works in 32-bit by building gdb and llvm in 32-bit mode and testing this stuff while running on a 64-bit OS. I would try setting a breakpoint in gdb on 'llvm::JITDebugRegisterer::RegisterFunction' to see that it is being called, and that getELFWriterInfo returns something. If that function actually

Hi, I am running Asterisk on Fedora Core 3. I am trying to use DDD to debug Asterisk. However, when I attach the debugger to the Asterisk Process, the Asterisk CLI promt hangs. Does not give any output, and Asterisk stops processing calls... What could be wrong and what is the best way to debug Asterisk...? Appreciate pointers.. Thx a lot, J --------------------------------- Do you

Hi Toni, I'm sorry, I haven't had much time to work on this today. When I run sshd (from the patched snapshot) in a debugger, with a breakpoint early in setup_sia(), this is what I find after connecting with a client: (1) There are two sshd processes. One is running as root, and the other as the user I logged with using the client. The root process is the one in the debugger,

I am using CentOS 4 GNU gdb Red Hat Linux (6.3.0.0-1.63rh) GNU DDD 3.3.9 (x86_64-redhat-linux-gnu) I bring up ddd on a program compiled -g and type: list function_name gdb seg faults. If I bring up ddd on gdb and then run gdb with the same program an type list function_name everything works just fine.

I tried to run gdb in linux with emacs But could not even run a simple example in the writing extensions tutorial. The execution history is as follows. Gdb worked fine for other debugging such as C++ codes. Thanks Han I started R at echo of emacs by typing (also tried other methods mentioned in the tutorial both in emacs and xterm.) M-x gdb ==> R -d gdb (gdb) run Starting program:

Hello Darren, Could you comment on this issue being raised by myself and Corinna Vinschen? This will create big problems for me. I'm not clear if this is a conscious decision supported by solid reasons or if it is just collateral damage. Thank you for all you work!

Hi all. As Corinna pointed out, there are some cases where sshd will log some authentications twice when privsep=yes. This can happen on any platform although it seems most obvious on the ones that don't do post-auth privsep. It also occurs when sshd logs to stderr (eg running under daemontools) or when you have a /dev/log in the privsep chroot. The patch below attempts to solve this for

I've always debugged the backend llc by running it as a separate executable. I'm seeing a bug that only happens when I run the compiler from clang. How do you debug this from gdb? I can put a breakpoint but it never stops when I say "run ...." Tia. Reed

Hi, there's a change made to 4.4p1, which gave some irritation on the Cygwin mailing list. It's a change from 20060907: - (djm) [sshd.c auth.c] Set up fakepw() with privsep uid/gid, so it can be used to drop privilege to; fixes Solaris GSSAPI crash reported by Magnus Abrante; suggestion and feedback dtucker@ NB. this change will require that the privilege separation user must
