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.

View 1 Replies View RelatedServer :: How To Create Kernel Dump On RHEL 4.7
Jan 11, 2011My application team is asking me to generate the kernel-dump.
Here are details about my server.
OS: RHEL 4.7/32 Bit
Kernel Version: 2.6.9-89.0.23.ELsmp
Processor: Intel(R) Xeon(R) CPU E5520@ 2.27GHz
Hardware: HP Proliant 380G6 series server.
I am using Electric Cloud applications. Sometimes it creates some kernel panic and immediately got rebooted. Kernel-debuginfo rpm is not installed. In some thread, I read the kernel-debuginfo rpm's version should match with the kernel version. In my case I couldn't even find the exact version of kernel-debuginfo version.
Server :: Disk Dump - Creating Virtual Directory
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.
Server :: Create Core Dump When My Application Crashes?
Dec 29, 2010I am using RHEL 4.7 (32bit) on HP Proliant 380G6 series server. We are using Electric Cloud Agents on these servers. Nowadays we are facing some memory issues and its creates some kernel panic and then restarts the server. When i reported the issue to my application team, they asked me to come with the core dump. I googled it enough, then i set ulimit value as unlimited. (previously it was 0, then i made a entry in /etc/profile file as follows
ulimit -c unlimited) But still whenever my server restarts due to that kernel panic, it couldnt generate the core dump. My application was installed on /opt
The attached document has the kernel panic logs
Server :: Dump All Users To The Same Sftp Starting Directory?
Jul 7, 2010Using CentOS 5.5. I have a handful of users that I need to have connect to my server via sftp and start in the same directory. for example, user1, user2, user3, etc.. will connect via sftp and upon connection will all be in the /some/dir/path/ftp-root directory.I know one way is to create these users all with the same 'home' directory, since by default a user starts in their home directory when connecting via sftp, but before just doing that, I wanted to find out if that is really the appropriate method to use? alternatives? Is there some setting on the sftp server end that could direct all users to one starting directory so that these users don't have to have the same 'home' dir? I'm using the sshd daemon that comes with CentOS 5.5 (with all current updates/patches)

View 1 Replies View RelatedUbuntu Installation :: Image Restore Grub Rescue Command Line
Feb 25, 2010I do computer forensics here in Afghanistan and I am trying to keep a clean image of a dual bootable hard drive. Here is what I try to do...
1. Boot into UbuntuLiveCD
2. I run "sudo dd if=/dev/zero of=/dev/sda conv=sync,notrunc bs=64K" to wipe the drive with all zeros.
3. I then install Windows by creating a new partician about 50GB.
4. I then install Linux by creating a partician in ext4 mounting it at '/' in addition I create a swap partician.
5. Next configure everything just the way I want it. I install all the drivers and software I need for my windows partician and build out the remaining part of the disc as a "data drive."
6. Then I use "dd" again to try to image my "clean slate" of a system. Remember I am dual booting. I dd the /dev/sda and gzip it.
7. When I go to restore it, I boot from the live CD again and unzip ig and "dd" it back onto /dev/sda.
8. I run fdisk -l and I get:/dev/sda1 * 1 6375 5120000000 7 HPFS/NTFS/dev/sda2 6376 11724 42965842+ 83 Linux/dev/sda3 11725 12453 ...... 82 Linux swap / Solaris.This means to me that it can "understand the file system"
9. But then when I take out the Live boot CD and try to get my "clean slate" machine back, the system goes into Grub Rescue mode with a grub command line "grub rescue>"
10. I tried using the tutorial on Grub2, but...
a. It would not understand the command "linux"
b. When I try to do insmod, it says it doesn't recognize the file system.
Ubuntu Security :: Failing On The First Command When Run Iptables-restore < File Location
May 4, 2010I'm setting up a server with Jaunty Jackalope version. I'm trying to test setting up a basic iptables rules... No matter which command I put in, it is failing on the first command when I run iptables-restore < file location (the first rule always fails). I'm doing this on the root user and first typing in the iptables rules in a test file. I've tried the first command starting with % sudo, iptables and -A. All have the same result. I've also tried letting the HTTP rule be first with the same result.

View 2 Replies View RelatedServer :: Automating A Restore With Backuppc?
Jan 28, 2011here is the thing. I've deployed BackupPC in a server at work, and everything is working fine. Now, what I need to do this thing. I have a remote server with a website and a postgres db running. I've been able to set up everything to be backed up using rsync. But I would like to make the same process to restore the backup immediately in a local server trough rsync, that has to be ready just in case of failure of the remote server. What I've tried to do is to run the DumpPostUserCmd, so whenever a dump is performed in the remote server, I can have my local server updated. What I've find out is that when you perform a restore through the web interface, the command that performs it is (using ps ax in the backuppc server):
/usr/bin/ssh -q -x -l root myserver.wheretodotherestore.mydomain /usr/bin/rsync --server --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --relative --ignore-times --recursive . /path/to/restore
So, what I could find out is: /usr/bin/rsync is the command that the process runs in the server where I want to put the restore. Then the options, and finally, source and destination of the restoration. But, as you can see, the source is '.' but I cannot guess where to point that!
Server :: How To Restore The /lib/libc.so.6 Link
Oct 27, 2010I've been working with out servers for the past several years. We have a mix of OS. Fedora, Ubuntu, RHEL, etc. I've accidentally trashed the libc.so.6 link and now nothing but shell commands work.
I tried to echo "/lib/libc-2.10.2.so into the /etc/sestatus.conf file, but that didn't have any affect. Does anyone know where the search path is maintained besides PATH so I can try to point the apps to the /lib/libc-2.10.2.so file? I have a bunch of SVN repos on this server and right now, no one has access.

View 6 Replies View RelatedUbuntu Networking :: Restore All Files To New Server?
Jun 29, 2010I'm trying to restore all my files to my new ubuntu server (a netbook actually) and can't! after copying for a few moments the samba shares stop working. in synaptic it says samba 2:3.4.7 as im typing this i realized I was able to copy a few large files when i was starting out so there may be some software added since thats the issue. In my scenario i found that the server does recover after a minute or two. but when copying large files it causes ALL networking to stop. funny that if i go to the server screen it is fine. Ive experienced this connecting with a windows 7 pc and a mac. the server will start responding again in a couple of minutes. when it locks up it locks up ALL networking: cant connect to the webserver, or ssh either when this happens. Just starts working again after 2 minutes. I am unable to sync this with my backup drive unfortunately.
I did some experimenting today and found that I was able to stay connected via ssh for well over an hour with no problems. as soon as I start copying files is when it happens. I use this as a server in a home office so I need to resolve this. for now going to share a drive off my router i guess. have been poring through the logs and reading everything i can on this the last few days.. I switched from network manager to WICD after reading about it online somewhere. that actually did help to apparently reduce the frequency of the issue.
does anyone have any tips? this is a new machine/install of Ubuntu 10.4 LTS desktop version (its just easier than the server version for me even though using as a server). its a new MSI X Slim X320. I bought it as it has the X530 Atom processor which is super efficient and I run this as a solar powered web/file/torrent/app server. In that regard im very pleased with it.
