从Centos服务器到ubuntu服务器scp很慢

wequst

从 Centos服务器到ubuntu服务器传送文件时使用scp 很慢。

我的语法为  time scp -v test user@1.2.3.4:/home/user/test

当执行到上面 标明颜色的 行时 速度非常慢。
大家遇到过这样的问题吗？
请指点。

sendltd

就是慢点嘛，有啥影响吗？
速度慢是ubuntu上/etc/ssh/sshd_config 参数的问题。
你可以比较下centos的/etc/ssh/sshd_config。
“Authentication”这一段ubuntu上打开的太多了。centos上基本都是注释掉的。
