Hi, I am currently running Apache (prefork) 2.0.55 under Ubuntu 6.06 LTS. Apache is running on a VPS with a limited amount of RAM so I have been investigating ways to limit the number of processes being opened per visitor. My MaxClients setting is set to 38 which is just about all the RAM I have for. However 99% of the time only 8-10 processes are in use. Occasionally someone will run a site ripper which uses 30+ threads and my MaxClients setting is then reached. New visitors will then face a delay. To try and solve this I have tried 2 Apache modules, mod_cband and mod_limitipconn - both have the ability to limit the number of connections allowed per IP. However, both seem to need to launch an Apache process before it can reject the connection with a 503, by which time the MaxClients limit has already been reached. Additionally I have investigated limiting the number of simultaneous connections per IP using iptables. However, due to a bug in Ubuntu's iptables, this option is not available to me. I cannot patch the kernel either, as I am using a VPS. So my question in simple terms is this: is there a way of limiting simultaneous connections per IP without having to launch additional processes to handle the rejections? Any help appreciated, Oliver. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
