PHREL v0.9.4 has been released.
PHREL is a per host rate limiter. It will track the rate of incoming traffic on a server and insert a chain into iptables when a configured threshold is crossed. The inserted chain may either rate limit or block the offending host for a period of time. The inserted chain is automatically removed when the offending host's traffic levels return to normal.
PHREL is particularly well suited to protecting nameservers (DNS) from random hosts that flood requests, and to preventing SSH brute force login attempts.
This new version includes (ChangeLog includes full details):
- Cleaned up SNMP trap code.
- Added support for startup, shutdown and restart SNMP traps.
- Added check for verifying iptables binary is valid and executable.
- Added support for include prefix ranges.
- Fixed typos in man page.
