There are several parameters that determine the maximum number of connections. Only one of them is an Apache parameter: MaxClients. In addition to this, there are system limits that restrict the number of connections a single process may accept. If you use the worker MPM of Apache 2.x, the maximum number of file descriptors that can be opened by a single process may be a factor, especially for a proxy. You can browse or set that limit using "ulimit -n" on Unices. Kernel parameters define a "hard" limit that cannot be exceeded, as well as a default "soft" limit. In Solaris those are rlim_fd_max and rlim_fd_cur. In Linux those parameters are set in the /proc file system (I believe it is /proc/sys/fs/file-max). -ascs ________________________________ From: paritosh mahana [mailto:paritosh.mahana@xxxxxxxxx] Sent: Monday, January 09, 2006 7:22 PM To: users@xxxxxxxxxxxxxxxx Subject: [users@httpd] Max number of connections from a single client to a server. Hi all, What is the max number of connection a server allows from a single client and how to change it(both in windows and linux). And how exactly the server determines the number of connections from a single client? I dont think it uses client's IP (there can be many people behind same NAT). I think this is based on session. Can someone enlighten me here. Thanks. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
