看到如下信息:

debug1: ssh_rsa_verify: signature correct

从debug1: No valid Key exchangecontext可以看出问题应该出在接收端服务器上的scp问题。

 

3,去接收端121.246上面查看scp

[[email protected] ~]# type scp

-bash: type: scp: not found

[[email protected] ~]#

果然不识别scp,试试yum安装,如下所示,无效:

[[email protected] ~]# yum install -y scp

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

*base: ftp.sjtu.edu.cn

*extras: mirrors.163.com

*updates: centos.ustc.edu.cn

Setting up Install Process

No package scp available.

Error: Nothing to do

[[email protected] ~]#

 

baidu到,yum安装scp包,是openssh-clients,所以重新yum安装

执行yum install openssh-clients* -y安装

 

ok,在check,scp已经能用了,如下所示

[[email protected] ~]# type scp

scp is /usr/bin/scp

[[email protected] ~]#

 

4,现在原来的服务器上scp就能成功了

[[email protected] soft]# scpjdk-7u55-linux-x64.tar.gz 192.168.121.246:/soft/

[email protected]'s password:

jdk-7u55-linux-x64.tar.gz 100% 132MB 131.8MB/s 00:01

[[email protected] soft]#

 

5,总结

scp成功,需要两个服务器都安装了scp服务才行。

1,scp报错 [[email protected] soft]# scpjdk-7u55-linux-x64.tar.gz 192.168.121.246:/soft/ [email protected] password: bash: scp: comma...
