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:
scp somefile.txt -i mykey.pem root@my.ec2.id.amazonaws.com:/
Password:
Any ideas why this is happening/how it can be prevented?
copy a file from a local server to a remote server
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
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:-
scp -i my-pem-file.pem username@source:/location/to/file username@destination:/where/to/put
-i is for the identity_file
I've used below command to copy from local linux Centos 7 to AWS EC2.
scp -i user_key.pem file.txt ec2-user@my.ec2.id.amazonaws.com:/home/ec2-user
scp -i ~/.ssh/key.pem ec2-user@ip:/home/ec2-user/file-to-copy.txt .
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.
In your case, the user root won't have any issues. But in certain cases where you're required to login under SSH as a different user, make sure the directory you're scp-ing has adequate permissions for the user you're SSH-ing.
#move your key to /tmp or right folder on server
sudo chmod 600 /tmp/dev-sunrobotics-snippetbucketcom.pem
scp -i /tmp/dev-snippetbucketcom.pem filestore.tar.gz ubuntu@85.111.5.33.98:/tmp
Make sure in your ip security you have allow ip address to connect
To use PSCP, you need the private key you generated in Converting Your Private Key Using PuTTYgen. You also need the public DNS address of your Linux instance
pscp -i C:\path\my-key-pair.ppk C:\path\Sample_file.txt ec2-user@public_dns:/home/ec2-user/Sample_file.txt
