#summary Connection-level rate limiting #labels Stage-Beta = Introduction = On some servers, especially public ones, it is desired to make sure that everyone gets their fair share of system resources (and no more). mod_limits allows you to specify traffic bandwidth limits, preventing any single connection hogging the server's CPU, RAM and bandwidth. = Details = mod_limits detects when a connection has exceeded its traffic allowance and temporarily ignores a connection. Due to the way TCP and the OS's network API works no data is lost, only slowed. = Configuration = Currently mod_limits is configured per connection type. The possible connection types are: * c2s * s2sin * s2sout * component The limits are specified like so in the *global* section of your config (they cannot be per-host): {{{ limits = { c2s = { rate = "3kb/s"; burst = "2s"; }; s2sin = { rate = "10kb/s"; burst = "5s"; }; } }}} All units are in terms of _bytes_, not _bits_, so that "kb/s" is interpreted as "kilobytes per second", where a kilobyte is 1000 bytes. = Compatibility = || 0.9 || Works || || 0.8 || Doesn't work(`*`) || (`*`) This module can be made to work in 0.8 if you do two things: # Install [http://hg.prosody.im/0.9/raw-file/d46948d3018a/util/throttle.lua util.throttle] into your Prosody source's util/ directory. # If you use libevent apply [http://prosody.im/patches/prosody08-mod-limits-fix.patch this patch] to net/server_event.lua.
