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.]]> http://www.cyberciti.biz/tips/linux-core-dumps.html/feed 18 http://www.cyberciti.biz/tips/apache-http-dos-tool-released.html http://www.cyberciti.biz/tips/apache-http-dos-tool-released.html#comments Fri, 19 Jun 2009 14:50:39 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=5138 Apache Security Update - a flaw In Apache can be used to carry out DoS. Slowloris is a new Apache DoS tool which can use slow Internet links to bring down Apache servers, rather than flooding networks. Most D/DoS tool requires faster net connections but this tool works with minimal bandwidth. This tool can lead to a DoS attack on Apache 1.x, 2.x, dhttpd, GoAhead WebServer, and Squid, while MS IIS6.0, IIS7.0, and lighttpd are confirmed not vulnerable to this attack.]]> http://www.cyberciti.biz/tips/apache-http-dos-tool-released.html/feed 9 http://www.cyberciti.biz/tips/rhel-fedora-centos-debian-ubuntu-lighttpd-mod_rrdtool.html http://www.cyberciti.biz/tips/rhel-fedora-centos-debian-ubuntu-lighttpd-mod_rrdtool.html#comments Sat, 23 May 2009 09:53:22 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=4878 The round-robin database tool aims to handle time-series data like network bandwidth, temperatures, CPU load etc. The data gets stored in round-robin database so that system storage footprint remains constant over time. Lighttpd comes with mod_rrdtool to monitor the server load and other details. This is useful for debugging and tuning lighttpd / fastcgi server performance. ]]> http://www.cyberciti.biz/tips/rhel-fedora-centos-debian-ubuntu-lighttpd-mod_rrdtool.html/feed 8 http://www.cyberciti.biz/tips/linux-unix-lighttpd-ipv6-support.html http://www.cyberciti.biz/tips/linux-unix-lighttpd-ipv6-support.html#comments Fri, 03 Oct 2008 20:30:32 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=3014 Lighttpd supports both IPv6 and IPv4 protocol out of box.
