[CLUE-Tech] wierd icmp syslog errors

[Michael Robbert]

Is this the same problem that you wrote here about in June? That is the
first thing that I found on google was your previous letter.
I have never used icmplogd, but my guess is that you have no route to
localhost(127.0.0.1).
You should have a line that looks like:
127.0.0.0     *        255.0.0.0       U     0      0        0 lo

I'm running RedHat and the loopback interface is configured in
/etc/sysconfig/network-scripts/ifcfg-lo which looks like:

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

If you're running something other than RedHat it may be configured in a
very different place.
