Hello,
I''m wrestling with a problem with an untypical
"network device" ... an UMTS card that should
connect my notebook to the internet.
There is no problem with this card, when I
use a vanilla kernel but with the Xen kernel
I have to adjust the MTU to 400 (default is
1500) in dom0
ifconfig ppp0 mtu 400
All other sizes don''t work. My service provider
(e-plus Germany) wasn''t able to help me, so
I''ve tried:
- all other kind of MTU sizes
- changed the TCP Maximum Segment Size (iptables)
- disabled Path MTU Discovery
- disabled compression in the kernel config
- stopped the xen bridge
I build my dom0 kernels with:
KERNELS ?= linux-2.6-xen0
in the Xen Makefile and I can''t see any TCP or UDP
checksum errors in ethereal.
My questions:
Could it be, that Xen changes something in the tcp
header that I''m not able to see with ethereal?
Regards
Ralf
