After getting ipip tunneling setup on 2.2.3 (the first 2.[12] series
kernel I've used for any length of time), I find I am getting TONS of icmp
messages logged by icmplogd, looks like two for every packet that is
recieved over the tunnel.
Here are the messages:
Mar 12 06:20:51 slacker icmplogd: source route from <addr of other end of
tunnel> [<ip of other end of tunnel>]
Mar 12 06:20:51 slacker icmplogd: destination unreachable from localhost
[127.0.0.1]
The tunnel seems to be working fine, and other than changes required by
the different networking setups between the kernels, the configs are
functionally equivalent as far as I can tell. The box on the other end of
the tunnel is a 2.0.36 kernel.
Maybe a case got missed in the icmp handling for tunnels? Why does the
kernel think that packets from the tunnel are source routed?
Any ideas or info would be appreciated.
