Background
I have a script on my NAS which is a Synology DS212J which is running on a special distro where uname -a gives me Linux DS212J 2.6.32.12 #4493 Wed Jul 16 11:37:16 CST 2014 armv5tel GNU/Linux synology_88f6281_212j which is suppose to run rsync to backup my Raspberry Pi running Raspbian (based on Debian).
The backup script looks like this
/usr/syno/bin/rsync -aEv --ignore-errors --delete --rsync-path="sudo usr/bin/rsync" --exclude-from=/volume1/backup_hdd1/rsync-pi/rsync-exclude.txt -e "ssh -p 22" [email protected]:/ /volume1/backup_hdd1/rsync-pi/backup >> /volume1/backup_hdd1/rsync-pi/rpi_backup.log 2>&1
Problem
The backup script was working until recently when I checked the logs where I'm getting multiple errors but they all can be traced back to these two lines:
Corrupted MAC on input.
Disconnecting: Packet corrupt
What I've tried
Disabled TCP checksum offload by this command
ethtool -K eth0 tx off rx off
And basically trying everything Google suggest. Sometimes it transfers up to 50 MBs where sometimes it only reaches a few MBs before aborting.
I'm completely lost since it was working flawlessly the other day. Only thing that I've done on the system is update a few programs - nothing major. I've also tried removing these programs but it didn't help.
Does anyone have any ideas or tips of what I can do to get it working again?
