scp出现stalled的原因和解决方法

IT技术学习阅读(1739)2018-11-21 收藏0次评论

When transferring large files(for example mksysb images) usingscp through a firewall, the scp connection stalls.

Cause:

The reason for scp to stall, is because scp greedily grabs asmuch bandwith of the network as possible when it transfers files,any delay caused by the network switch of the firewall can easilymake the TCP connection stalled.

Solution:

There’s a solution to this problem: Add “-l 8192″ to the scpcommand.

Adding the option “-l 8192″ limits the scp session bandwith upto 8192 Kbit/second, which seems to work safe and fast enough (upto 1 MB/second):

以上就是scp出现stalled的原因和解决方法的全部内容。
