Ticket #3766 (closed defect: fixed)
TCP checksum doesnot work
|Reported by:||werner.frerichs||Owned by:|

Description (last modified by frank) (diff)
Transfering large data using scp or ssh breaks with the message "Corrupted MAC on input." . This can be a bug in Virtualbox, Hardware, ... or something else. Transfering data using http for examble new packages, updates, ... never breaks because http doesnot check the transport twice (tcp should do this), so the packages are corrupt (wrong md5sum or gunzip cannot open).
I don't know, if the corruption of the transport belongs to a bug in my hardware or in the device driver for the virtual network interface, but there must be a chance to enable TCP checksum to avoid corrupted data.
I found an article/bug report on xensource which describ this better. http://lists.xensource.com/archives/html/xen-users/2006-01/msg00741.html
