from debug1:no valid Key exchangecontext can see that the problem should be on the receiving side server SCP problem.

3, go to the receiving end121.246View aboveSCP

[[Email protected] ~]# type SCP

-bash:type:scp:not found

[Email protected] ~]#

It sure does not recognize the SCP, try Yum installation, as seen below, invalid:

[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 to, Yum installation SCP Package, yes openssh-clients , so once again Yum installation

Run yum install openssh-clients*-y installation

Ok. It's already available in CHECK,SCP. For example, the following can be seen

[[Email protected] ~]# type SCP

SCP IS/USR/BIN/SCP

[Email protected] ~]#

4, now on the original serverSCPit will be successful.

[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, summarize

SCP is successful and requires two servers to have an SCP service installed.
