Hi,
on a fairly new 6.1-stable, and probably before, once in a
blue moon, sendto return error 64 (EHOSTDOWN?). but the packet seems to have

everything keeps on working.
what is error 64?
danny
EHOSTDOWN comes from the ARP layer of the IP stack, and would be
consistent with the host either getting no arp response or rejected
responses from the target. It would be useful to run tcpdump+ethereal
on your connection to see what is really going on.
too much traffic, and would be like looking for a needle in a haystack.
(i can't reproduce this at will)
the question is, if it was an error, how come the packet did go out.
need more proof for the above statement - working on it.

I find that ethereal does a great job of associating packets and making
it easy to sort through mountains of data. It's not so good at actually
collecting the packets, so I run tcpdump in raw collection mode and then
feed the output to ethereal for analysis. Having tcpdump generate a
circular ring of files that are at most 20MB works best.
