Description dsummers 1999-07-21 16:45:03 UTC
This seems to be more a problem with 2.2 kernels in general,
but I thought I'd bring it to your attention. In certain
network environments, the 2.2 kernel reports quite few
invalid error messages from routing devices. Since ICMP is
built into the kernel, the messages pop to the console,
which is a mild to ehavy annoyance, depending on what you
are trying to do on the console.

echo "3 5 1 7" into /proc/sys/kernel/printk removes the
console logging problem, but IMHO this is something that
should be looked at as a deeper minor issue to contend with.

------- Additional Comments From   07/22/99 11:36 -------
A fix found is to set a switch in /proc/sys/net/ipv4 to 1:
The command to do this would be:
    echo "1" > icmp_ignore_bogus_error_responses
