mod_limits
This module adds rate-limiting for XMPP sessions, limiting excessive bandwidth usage by clients and remote servers.
Usage
= {
modules_enabled -- Other modules
"limits"; -- Enable rate-limiting module
}
Extra configuration required to enable the limits is described below.
Configuration
Option | Default | Notes |
---|---|---|
limits |
{} |
Sets the limits for each session type |
limits_resolution |
1 |
Sets the time that an over-limit session is suspended for |
unlimited_jids |
{} |
Set of JIDs exempt from limits (added in 0.12) |
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 = "3kb/s";
rate = "2s";
burst };
= {
s2sin = "10kb/s";
rate = "5s";
burst };
}
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.
