New kernel 2.2.0 and ICMP ?

Post by Bob » Sun, 28 Feb 1999 04:00:00



RH5.2.
I compiled new kernel 2.2.0.
I am getting
209.**.**.*** sent an invalid ICMP error to a broadcast messages
every 15 sec.
This never happened in 2.0.36 kernel.
Any idea how to fix it ?
thanks

Hi Bob,

The source does state:
    /*
     *  Check the other end isnt violating RFC 1122. Some routers send
     *  bogus responses to broadcast frames. If you see this message
     *  first check your netmask matches at both ends, if it does then
     *  get the other vendor to fix their kit.
     */

You can do an

echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses

to get this check to be ignored.
