HowTo: Debug Crashed Linux Application Core Files Like A Pro

Posted on in Categories Linux, Troubleshooting last updated June 18, 2010

Core dumps are often used to diagnose or debug errors in Linux or UNIX programs. Core dumps can serve as useful debugging aids for sys admins to find out why Application like Lighttpd, Apache, PHP-CGI or any other program crashed. Many vendors and open source project author requests a core file to troubleshoot a program. A core file is generated when an application program abnormally terminates due to bug, operating system security protection schema, or program simply try to write beyond the area of memory it has allocated, and so on. This article explains how to turn on core file support and track down bugs in programs.

How A Microsoft Veteran Learned To Love Linux And Why It Matters

Posted on in Categories Linux, Windows, Windows server, windows vista last updated June 18, 2009

Great article.

“After The Software Wars”, is a new book in which former Microsoft employee Keith Curtis explores the worlds of proprietary and free software. Quoting from the article:

While I came to not be all that thrilled with Fedora itself, I was floored merely by the installation process. It contained a graphical installer that ran all the way to completion, it resized my NTFS partition — which I considered a minor miracle, setup dual boot, and actually did boot, and let me surf the Web. I didn’t have a clue what to do next, but the mere fact that this all worked told me more about the potential of Linux than anything I had read so far. You cannot, by accident, build an airplane that actually flies.

Important: Openssl Security Update [CVE-2008-5077]

Posted on in Categories CentOS, Debian Linux, fedora linux, FreeBSD, GNU/Open source, Howto, Linux, News, RedHat/Fedora Linux, Security Alert, Slackware, Suse Linux, Sys admin last updated January 8, 2009

Linux / BSD and UNIX like operating systems includes software from the OpenSSL Project. The OpenSSL is commercial-grade, industry-strength, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as general purpose cryptography library.

The Google security team discovered a flaw in the way OpenSSL checked the verification of certificates. An attacker in control of a malicious server, or able to effect a “man in the middle” attack, could present a malformed SSL/TLS signature from a certificate chain to a vulnerable client and bypass validation.

This update has been rated as having important security impact on FreeBSD, all version of Ubuntu / Debian, Red Hat (RHEL), CentOS, Fedora and other open source operating system that depends upon OpenSSL.
