Description pmweidne 2000-01-10 23:01:42 UTC

Console constantly logs:

xx.xx.xx.xx sent an invalid ICMP error to a broadcast

Have seen on mailing lists that this can be turned off by
editing /usr/src/linux/net/ipv4/icmp.c and commenting out the printk OR
echoing "1" to /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts (which
doesn't work anyway).

Is there a patch for this problem - I couldn't find the bug listed
anywhere in bugzilla?

The default behaviour is correct. Its warning you something on your network
needs major brain surgery to comply with standards. And you can turn it off as
you have noted if you cant fix your broken network or are sharing it
