This exercise looks exactly the same if you login to either host2 or host3 and copy the local files to the other remote systems. These numbers would be different if the file had any size to it. The files are empty and therefore you see that the size is 0 and the transfer rate is 0.0KB/s.
#SSH COPY A DIRECOTY FULL#
You must specify the full path to the destination file. Make normal happenįor testing purposes, create a new file on each system in your home directory as, so that one host1 you have host1.txt, on host2 you have host2.txt, and on host3 you have host3.txt.Īs a preliminary, non-magical exercise, login to host1 and copy the host1.txt file to host2 and to host3. $ ssh-copy-id $ ssh-copy-id ssh-copy-id ssh-copy-id copies keys among all hosts so that now any SSH-type transaction to or from any host will be passwordless. Now, any SSH-type transaction will be passwordless from host1 to host2 and from host1 to host3. RSA key fingerprint is SHA256:Y0X9C7rVNiRgM4yuBH8DUOUed5d/N57VYO+aoRmXmP4. The authenticity of host 'host3 (10.10.1.70)' can't be established. Now try logging into the machine, with: "ssh check to make sure that only the key(s) you wanted were added.Īnd now issue the same command from host1 to host3 (10.10.1.70) $ ssh-copy-id INFO: Source of key(s) to be installed: "/home/khess/.ssh/id_rsa.pub"
#SSH COPY A DIRECOTY INSTALL#
usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed - if you are prompted now it is to install the new password: usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed The authenticity of host 'host2 (10.10.1.60)' can't be established.ĮCDSA key fingerprint is SHA256:fM/5eaHGa37W+0xq4QZfL+Y6NobRbCVH1G4uhQLAwMw.Īre you sure you want to continue connecting (yes/no)? yes Issue the following commands from host1 to host2 (10.10.1.60) $ ssh-copy-id INFO: Source of key(s) to be installed: "/home/khess/.ssh/id_rsa.pub" This is the easiest method for exchanging keys among hosts.
#SSH COPY A DIRECOTY PASSWORD#
This step must be performed on all hosts in both directions so that file transfers and other SSH-type connection may proceed unfettered by password prompts.
Repeat this process on host2 and on host3. You have generated the SSH key for this host. You won't see those entries in your terminal window. SHA256:XWk+zJ5Kphe/sT78yg1jLdQCybN4dE2o52eOihEuwPo key's randomart image is:Īccept the defaults by pressing the ENTER key three times to continue as shown above.
Your public key has been saved in /root/.ssh/id_rsa.pub.
Your identification has been saved in /root/.ssh/id_rsa. $ ssh-keygenĮnter file in which to save the key (/root/.ssh/id_rsa): Įnter passphrase (empty for no passphrase): Login to host1 and issue the following command to generate the SSH key. The table below might be a clearer way of presenting this scenario. Actually, this step is optional, but to make your life easier, I recommend that you perform it.įor the sake of simplicity in this example, we have three systems: host1, host2, and host3 that use IP addresses 10.10.1.50, 10.10.1.60, and 10.10.1.70, respectively.
