Answer 2

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

Answer 3

I was hung up on this because I was specifying my public key file in

scp -i [private key file path]

When I caught that mistake and changed it to the private key path instead, I was all set.

I figured it out. I had the arguments in the wrong order. This works:

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

Answer 5

My hadoopec2cluster.pem file was the only one in the directory on my local mac, couldn't scp it to aws using scp -i hadoopec2cluster.pem hadoopec2cluster.pem ubuntu@serverip:~.

Copied hadoopec2cluster.pem to hadoopec2cluster_2.pem and then scp -i hadoopec2cluster.pem hadoopec2cluster_2.pem ubuntu@serverip:~. Voila!

Answer 6

write this code

scp -r -o "ForwardAgent=yes" /Users/pengge/11.vim root@192.168.2.228:/root/

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.
