# scp

-bash: scp: command not found

# which scp

/usr/bin/scp

# rpm -qf /usr/bin/scp

openssh-clients-4.3p2-72.el5

# yum install openssh-clients

或者从光盘上安装

# rpm -ivh libedit-2.11-4.20080712cvs.1.el6.x86_64

# rpm -ivh openssh-clients-5.3p1-20.el6.x86_64

如果还报错，bash: scp: command not found

lost connection

本地是有scp命令的,密码输入也是正确的

加-v参数查看详细过程,认证已经通过,判断应该是远端服务器的scp命令没有安装.
