copy a file from a local server to a remote server

<pre><code>sudo scp -i my-pem-file.pem ./source/test.txt ec2-user@1.2.3.4:~/destination/

copy a file from a remote server to a local machine

<pre><code>sudo scp -i my-pem-file.pem ec2-user@1.2.3.4:~/source/of/remote/test.txt ./where/to/put

So the basically syntax is:-

<pre><code>scp -i my-pem-file.pem username@source:/location/to/file username@destination:/where/to/put

<code>-i</code> is for the identity_file

The file name shouldnt be between the pem file and the ec2-user string - that doesnt work. This also allows you to reserve the name of the copied file.

blocks|key|3295032|text|在您的例子中，用户root不会有任何问题。但在某些情况下，您需要以不同的用户身份在SSH下登录，请确保您的scp-ing目录对您要使用SSH的用户具有足够的权限。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3295033|entityMap^0|9|4|1H|3|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

If you have a SSH key with access to the destination server and the source server does not, adding -o "ForwardAgent=yes" will allow you to forward your SSH agent to the source server so that it can use your SSH key to connect to the destination server.

Just tested:

Run the following command:

Then:

<ol>
<li>create ami (image of the ec2).</li>
<li>launch from new ami(image) from step no 2 chose new keys.</li>
</ol>

I have an EC2 instance running (FreeBSD 9 AMI ami-8cce3fe5), and I can ssh into it using my amazon-created key file without password prompt, no problem.

However, when I want to copy a file to the instance using scp I am asked to enter a password:

<pre><code>scp somefile.txt -i mykey.pem root@my.ec2.id.amazonaws.com:/

Password:
</code></pre>

Any ideas why this is happening/how it can be prevented?

我有一个正在运行的EC2实例(Amazon9AMIAMI-8cce3fe5)，我可以使用我的FreeBSD创建的密钥文件ssh进入它，没有密码提示，没有问题。但是，当我想使用scp将文件复制到实例时，系统会要求我输入密码：scp somefile.txt -i mykey.pem root@my.ec2.id.amazonaws.com:/Password:你知道为什么会发生这种情况/如何预防吗？
