On my LAN my routeur always forces the mtu of my laptops to 1492. I have
a laptop with debian sid and an eeepc with debian stable lenny. On this
LAN I have a NAS (readyNAS duo of Netgear). With my laptop with sid I
don't have any problem at all to upload/download file from my NAS with
ftp/cifs/NFS and with firestarter installed. But with my eeepc (with
ethernet atl1c) I get one:
- with firestarter installed
- with an mtu set to 1492
I can't download file from my NAS through ftp/cifs/NFS. But I can upload
So I have a little bit researched on the problem:
- with mtu of 1500 on my eeepc the problem disappears. even firestarter
- the net.ipv4.tcp_timestamps value ist set to 0 by firestarter. When I
force it to 1 it works out of the box even with an mtu of 1492.
