Linux users of Sony Z1 series

[Brouard Nicolas <>]

Many thanks to all the people who sent me their download tests
concerning this problem which help us to understand the problem.

We have 3 successive routers at INED, from the internal network until
Internet, but if we branch a Linux laptop at each intermediate node, he
can successively upload to or download from the Internet. It is only
when we have to go through the 3 chained routers that the connection
breaks. Strange!

If we don't know yet what is wrong, the workaround consists in setting a
low mtu on each of our internal Linux boxes (as for the mailing list
server). Default MTU is 1500 and we set it to 500 by "ifconfig eth0 mtu
500". May I ask some of you to test again on
http://sauvy.ined.fr/~brouard/sony/rpm with this workaround.

Only a few of you, like Ionut (Ionut is always lucky: able to resume
from RAM without video_post etc...) have been able to download from a
Linux box when our server had the default 1500 MTU. What about our new
500 setting?

In fact, windows clients do also have a default 1500 MTU, thus linux
clients ipconfig do have other properties, different from Windows, which
make our 3 chained routers confuse.

Cheers,
Nicolas
