scp (secure copy) to ec2 instance without password

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:/

---

scp -i /path/to/your/.pemkey -r /copy/from/path user@server:/copy/to/path

---

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

Making siliconerockstar's comment an answer since it worked for me

scp -i kp1.pem ./file.txt ec2-user@1.2.3.4:/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.

---

lets assume that your pem file and somefile.txt you want to send is in Downloads folder

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

let me know if it doesn't work

---

scp -i /home/barkat/Downloads/LamppServer.pem lampp_x64_12.04.tar.gz

this will be very helpful to all of you guys

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!

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.

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.

---

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

---

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.

For ec2 server

#move your key to /tmp or right folder on server

Assign right permission

sudo chmod 600 /tmp/dev-sunrobotics-snippetbucketcom.pem

Than connect to server or transfer

scp -i /tmp/dev-snippetbucketcom.pem filestore.tar.gz ubuntu@9.911.99.91:/tmp

Make sure in your ip security you have allow ip address to connect

Just tested:

Run the following command:

sudo shred -u /etc/ssh/*_key /etc/ssh/*_key.pub

Then:

create ami (image of the ec2). launch from new ami(image) from step no 2 chose new keys.
