Even with duplicate entries everything works as expected. If you execute ssh-copy-id multiple times on the local-host, it will keep appending the same key on the remote-host’s authorized_keys file without checking for duplicates.

Duplicate entry in authorized_keys: I wish ssh-copy-id validates duplicate entry on the remote-host’s authorized_keys.

The agent has no identities: When the ssh-agent is running and the ssh-add -L returns “The agent has no identities” (i.e no keys are added to the ssh-agent), the ssh-copy-id will still copy the message “The agent has no identities” to the remote-host’s authorized_keys entry.

If two or three of them exist, it should copy identity.pub as default. i.e If any one of them exist, it should copy that to the remote-host.

Instead, I wish it uses id_dsa.pub, or id_rsa.pub, or identity.pub as default keys. Default public key: ssh-copy-id uses ~/.ssh/identity.pub as the default public key file (i.e when no value is passed to option -i).Three Minor Annoyances of ssh-copy-idįollowing are few minor annoyances of the ssh-copy-id.

If you have loaded keys to the ssh-agent using the ssh-add, then ssh-copy-id will get the keys from the ssh-agent to copy to the remote-host. usr/bin/ssh-copy-id: ERROR: No identities found When no value is passed for the option -i and If ~/.ssh/identity.pub is not available, ssh-copy-id will display the following error message.

If you are using SSH2, we discussed earlier about performing SSH and SCP without password from SSH2 to SSH2, from OpenSSH to SSH2 and from SSH2 to OpenSSH. We also discussed earlier in detail about performing SSH and SCP from openSSH to openSSH without entering password. The above 3 simple steps should get the job done in most cases. Step 3: Login to remote-host without entering the password ssh remote-host Note: ssh-copy-id appends the keys to the remote-host’s. To make sure we haven't added extra keys that you weren't expecting. Now try logging into the machine, with 'ssh 'remote-host'', and check in: Your public key has been saved in /home/jsmith/.ssh/id_rsa.pub.ģ3:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 Step 2: Copy the public key to remote-host using ssh-copy-id ssh-copy-id -i ~/.ssh/id_rsa.pub password: Your identification has been saved in /home/jsmith/.ssh/id_rsa.

This article also explains 3 minor annoyances of using ssh-copy-id and how to use ssh-copy-id along with ssh-agent. ssh-copy-id also assigns proper permission to the remote-host’s home, ~/.ssh, and ~/.ssh/authorized_keys. ssh-copy-id copies the local-host’s public key to the remote-host’s authorized_keys file. Ssh-keygen creates the public and private keys. ssh folder and files is as follows:Īny help/guidance you might be able to provide would be greatly appreciated.You can login to a remote Linux server without entering password in 3 simple steps using ssky-keygen and ssh-copy-id as explained in this article.

Also, in doing some digging, it appears the CHMOD command is no longer allowed? The SMB share I have setup on my FreeNAS in order to allow my Windows systems to map the network drive does have the 'Apply Default Permissions' box checked. I have a feeling this has something to do with permissions, but I am not sure. When I try to connect using these keys, I get a 'Disconnected: No supported authentication methods available (server sent: publickey) Server refused our key' error.

I have then imported that key into PuttyGen and saved it on my Windows system. ssh/ directory and copied the key into a file name 'authorized_keys' in the same. I have created a public/private key on my FreeNAS. I have been following a number of guides, listed below: I am trying to setup SSH authentication utilizing public/private key pairs.
