Spammers, abuser and badly written bots can eat up all your bandwidth. A webserver must keep an eye on connections and limit connections per second. This is serving 101. The default is no limit. Lighttpd can limit the throughput for each single connection (per IP) or for all connections. You also need to a use firewall to limit connections per second. In this article I will cover firewall and lighttpd web server settings to throttle end users. The firewall settings can be applied to other web servers such as Apache / Nginx and IIS server behind PF / netfilter based firewall.]]> http://www.cyberciti.biz/tips/lighttpd-set-throughput-connections-per-ip.html/feed 15 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 nixCraft 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.

FastCGI supports connection via UNIX sockets or TCP/IP networking. This is useful to spread load among various backends. For example, php will be severed from 192.168.1.10 and python / ruby on rails will be severed from 192.168.1.11. This is only possible with mod_fastcgi. ]]> http://www.cyberciti.biz/tips/rhel-fedora-centos-apache2-external-php-spawn.html/feed 8 http://www.cyberciti.biz/tips/debian-php-5-security-issues.html http://www.cyberciti.biz/tips/debian-php-5-security-issues.html#comments Thu, 27 Nov 2008 04:49:16 +0000 nixCraft http://www.cyberciti.biz/tips/?p=6093 Debian 5 php5 package has serious security issues as follows: To prevent Denial of Service attacks by exhausting the number of available temporary file names, the max_file_uploads option introduced in PHP 5.3.1 has been backported.]]> http://www.cyberciti.biz/tips/debian-php-5-security-issues.html/feed 2 http://www.cyberciti.biz/tips/wordpress-redirecting-tag.html http://www.cyberciti.biz/tips/wordpress-redirecting-tag.html#comments Wed, 08 Oct 2008 20:24:52 +0000 nixCraft http://www.cyberciti.biz/tips/?p=3064 Recently, I had noticed lots of 404 error generated by my wordpress software.
