Beta Branch update centmin.sh menu option 21 submenu 1 in 140.00beta01

update centmin.sh menu option 21 submenu 1 in 140.00beta01

- update centmin.sh menu option 21 submenu option 1 option 3 for creating new SSH key for remote host. Previously, when it comes time to transfer the new generated SSH key's public key file to the remote host via ssh-copy-id, if the ssh-copy-id process fails, the routine will automatically remove the generated SSH key pairs' private and public key files. This update will improve the routine so that on ssh-copy-id failed transfer, prior to removing the SSH key pairs private and public key files, it will show the contents of both private and public key files. This can save time if you had a temp remote SSH server issue or restriction i.e. firewall or root user SSH restriction on remote host, and you do not want to re-run centmin.sh menu option 21 submenu option 1's option 3 again as you can use the displayed contents to manually recreate the SSH private and public key file contents.

Which stage or centmin.sh menu option 21 do you get permission denied, data backup or backed up data file transfer and how are you transferring the data? It would help if you specifically output the steps and submenu options you chose and where you got the permission denied messages. With that said, the centmin.sh menu option 21 does assume full root user right now, so if you can provide the info and where you get the issues, I can look at adding sudo user support.

see https://centminmod.com/menu21-140.00beta01

 

Ah the screenshot shows it's during tunnel-transfer.sh script stage. I've just updated Centmin Mod 131.00stable and 140.00beta01 with fixes to support sudo user on transfers. Run cmupdate to get the latest fix and then it should work, let me know.

If you do not want to re-run entire backup, just re-run that screenshot's command exactly and it should work provided remote server's non-root sudo user was setup correctly.
