一.无法SCP报告

[root@zj2 webapps]# scp -r  monitor root@210.21.118.214:/tmp
command-line: line 0: Bad configuration option: PermitLocalCommand
lost connection


二.查SCP操作的本机SSH 属性

[root@server01 bin]# lsattr ssh

-u--ia------- ssh

 

对比其他server上的ssh程序权限和属性看了一下:

root@sc211 .ssh]# lsattr /usr/bin/ssh
------------- /usr/bin/ssh


三.用chattr修改属性

于是将ZJ2上的ssh属性将uia去掉，命令：

chattr -uia /usr/bin/ssh

再重启sshd服务，问题即可解决！

service sshd restart




四.还有些SCP故障,是因原来SCP过,后对方HOSTNAME又更改了,可检查:
本机的$HOME/.ssh/authorized_keys,改正HOSTNAME










另外:
[root@web1 webapps]# scp -r ./billing root@192.168.87.80:/tmp/
