Oct 7, 2009I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.

Apr 14, 2010I'm quite new to linux, but I've managed to grasp some basics. Now my intention here to create a virtual directory, which I resorted to creating an Image File so that I can mount it and have my folder have a dedicated storage. I will mount this image as a loop device. Well it's not much of a problem, but I would like to know whether this is suitable. Say I want to create a 25GB Image.
Code:
dd if=/dev/zero of=/home/disk-img/25GB.ext3 bs=1G count=25
Is this recommended? I'm using block size as 1G which is really huge, so I was wondering, if this is actually recommended. From what I read, some said that it's only advisable to use 4096k or lower, but what I found was that these suggestions are very dated (year 2003), and it is now 2010, so I would like to know if it makes any big differences.

Debian :: Creating New Profiles Based On Existing Profile In Gnome
Oct 8, 2010I'm setting up my profile in gnome right now, with things like fonts, themes, wallpapers, iceweasel settings, menu settings, and I'm going to be adding a couple new users. Rather than re-do everything again, I thought I'd just create the new user, copy over my home dir, chown it to the new user and then login to make minor final adjustments, like specifiying where the music dir is and such.Just wondering if there'd be any problems with this, since it's just an idea I think should work but have never tried it. Any experience, or warnings?

View 2 Replies View RelatedGeneral :: Mount A Hard Drive With Pre-existing File System And Data?
Mar 23, 2010I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.
It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such
Found Disk: hda
Found Disk: sdb
so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on
cyberciti.biz/faq/freebsd-adding-second-hard-disk-howto/
but I'm assuming FreeBSD would work differently and I wasn't totally sure what the labels of the file systems should be.
Debian Multimedia :: Getting The Subtitles To Be Included In The File Dump.vob?
Jul 1, 2011Doing this: mplayer dvd://1 -v -dumpstream -dumpfile dump.vob Gives me all the audio tracks, but not the subtitles. How can I go about getting the subtitles to be included in the file dump.vob? I've tried something like: mplayer dvd://1 -v -sid 5 -dumpstream -dumpfile dump.vob (where -sid 5 was the correct subtitle) but this does not work. I'm going to use mencoder to make an .avi file (with subtiutles, obviously), so I could, as a last resort, use some other program that extracts the subtitles (suggestions?).
