Bug#377024: nfs_common: nfs client crash nfs server? ; [TCP CHECKSUM INCORRECT]

jeanmichel.123
2 additional information:

the checksum is bad:
* with NFS and SMB over TCP, but not with telnet.
* only in TCP blocks wich size (Len under ethereal) is not null

this means checksum is good with both telnet blocks empty TCP blocks.

Moreover on another computer, without the upgrade, NFS seams to work with UDP
instead of TCP!

Unless ethereal give bad information?

I am not used to these protocols, and do not know what to do with that.

Any idea?

Not surprising; remember that nfs and smbfs is handled by the kernel. I'm not
surprised if it takes another path somehow.

That's interesting; unfortunately, I know nothing about the kernel NFS code,
so you'll have to take this up with the kernel people.
