Re: [Xen-users] routing in xen 3.0 domU: icmp gets routed, but tcp/ip on
Quoting Florian Kirstein <xenlist@xxxxxxxxxxxxxx>:
I have a really strange routing problem
from my experience, most of the "ICMP works but TCP seems connected
and no data gets through" problems in routed xen3 setups are due to
thecheksum-offloading featue. [snip]
To see if you've really got the checksum problem use tcpdump -vv in
the > Domain not receiving data. For example:
tcpdump -vv -n -i eth0 and then transfer some tcp or udp data to it.
If you see something like [bad udp cksum f566!]
I get "cksum 0x7fe9 (incorrect (-> 0x3470)", so it looks like
the checksum offloading problem you described.
Applied the patch, installed the new dom0 kernel (and new domU
for good measure) and now routing works fine!
May I suggest The Powers That Be to include this patch in the
upcoming 3.0.2 release? First make it work, _then_ make it fast ;-)
Many thanks, Peter
