用SSH恢复备份时候出现的Corrupted MAC on input
因为把一台机器重装了Debian之后要恢复,在备份机上运行
tar czf – mysql| ssh root@重装机IP tar xzf – -C /data
结果出现
Received disconnect from 重装机IP: 2: Corrupted MAC on input.
从字面意思就能开出来是网卡中断,Google了一下,找到了解决方案(未必是最佳的).
apt-get install ethtool
ethtool -k eth0
可以看到过载保护的内容
Offload parameters for eth0:
Cannot get device flags: Operation not supported
Cannot get device GRO settings: Operation not supported
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: off
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: off
large-receive-offload: off
ntuple-filters: off
receive-hashing: off
关闭RX的过载保护
ethtool -K eth0 rx off
然后就没事了.弄完了记得改回来就可以.
