  Hi,

   

  Can you try and do:

  ssh-copy-id -oPort=xxxx [ClusterControl IP address]
  
  However, you *must* also setup password less SSH between the controller and the data nodes you wish to use in the cluster. The above will only do it between the computer you are executing the command on and to the [ClusterControl IP address].

   

  THanks

  For me it looks like this:
  
  

  ssh-copy-id -oPort=2222 10.10.10.10
  /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

  /usr/bin/ssh-copy-id: ERROR: ssh: connect to host 10.10.10.10 port 2222: Connection refused
  
  When i have executed the cmd (now there is no sshd on port 2222, hence the conn refused).

  Hi,
  
  Please double check you really have an identitiy file:

  ls ~/.ssh/id_rsa

Else re-run

  ssh-keygen -trsa

  just press enter on any question (or 'yes' to overwrite in case of overwriting an existing).

  What output do you get from the ssh-keygen program? Can you paste it here (except any key data)?

And then


  ssh-copy-id -oPort=9898 101.101.101.1

  Hi, had already done the renew key, but i`ll do it again..

   

  /root/.ssh/id_rsa already exists.
  Overwrite (y/n)? y
  Enter passphrase (empty for no passphrase):
  Enter same passphrase again:
  Your identification has been saved in /root/.ssh/id_rsa.
  Your public key has been saved in /root/.ssh/id_rsa.pub.
  The key fingerprint is:
  xx:xx:xx:xx:xx:xx:<rest snipped> root@xxxx.xxxx
  The key's randomart image is:
  +--[ RSA 2048]----+
  | .o o..oo |
  | * ... |
  | o o o |
  | + . + o |
  | = = E |
  | . = + o |
  | + . . |
  | o |
  | |
  +-----------------+
  
  [root@cluster ~]# ssh-copy-id -i -oPort=1886 xxx.xxx.xxx
  /usr/bin/ssh-copy-id: ERROR: No identities found
  [root@cluster ~]#

  Hi,

  [root@cluster ~]# ssh-copy-id -i -oPort=1886 xxx.xxx.xxx
  /usr/bin/ssh-copy-id: ERROR: No identities found
  [root@cluster ~]#

   

  here you specify -i   , but no path to the file, so i believe that is why it complains.

  
  Please do (taking out the -i ):
  
  ssh-copy-id -oPort=1886 xxx.xxx.xxx
  
  Do you have different SSH ports on the different servers?

  & same  port on all servers

  Hi 

  What happens if you try

  $ ssh-copy-id "root@<host> -p 9898"
  
  
  

  Best Regards,

  Alex

  You could create/alter the ~/.ssh/config file on the host you are executing the ssh-copy-id from, and provide the port number in there with these lines:

  Host 101.101.101.*
  Port 1886

  The underlying ssh command would then use these settings to connect.
