Hi, I have the same issue with a dapper server. In my case not only happen with scp to another machine. Sometimes just after login in via ssh.
In the same switch there are anothers ubuntu dapper server without problem, so I think is a driver issue. The machine have two same nics and in both occurs the same issue. The nics are Intel 82546EB Gigabit Ethernet in a Dell Poweredget 650 and the driver is e1000 -- Large file transfer gives error: Corrupted MAC on input https://launchpad.net/bugs/60764 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
