scp到Amazon EC2失败,但ssh工作

我有一个EC2实例正在运行.我可以ssh没有问题:

ssh -i mykey.pem ec2-user@someIPaddress

.但是,scp失败了.运行这个:

scp -vvv -i mykey.pem test.txt ec2-user@someIPaddress:/tmp/

产生以下结果:

Executing: program /usr/bin/ssh host someIPadress, user ec2-user, command scp -v -t /tmp/

其他信息:

>我的.pem键只对我自己具有读写权限(-rw ——-).
>我被告知如果在EC2上运行/ bin / true产生非空行,scp可能存在问题,但这不是这种情况:

[ec2-user@someIPaddress ~]$/bin/true
[ec2-user@someIPaddress ~]$

>我验证了test.txt存在:)
>我通过ssh登录验证了我可以写入/ tmp.

我很惊讶ssh有效,但不是scp.有任何想法吗?

编辑:正在运行

ssh -vvv -i mykey.pem ec2-user@someIP

此问题的另一个原因(SCP在SSH成功​​的地方失败)在登录期间向控制台打印了任何消息(例如,从.bashrc脚本)
