ip_icmp_err_interval and ip_icmp_err_burst

Description

Controls the rate of IP in generating IPv4 or IPv6 ICMP error messages. IP generates only up to ip_icmp_err_burst IPv4 or IPv6 ICMP error messages in any ip_icmp_err_interval.

The ip_icmp_err_interval parameter protects IP from denial of service attacks. Setting this parameter to 0 disables rate limiting. It does not disable the generation of error messages.

Default

100 milliseconds for ip_icmp_err_interval
