Passwordless logins by ssh-keys
RsyncUI utilizes user set ssh keypath and identityfile. Default values for ssh are
~/.ssh/id_rsa and portnumber
22. It is not required to set your own values for key path and identityfile if default values are used. The ssh parameter within the rsync command is, if set by the user:
-e "ssh -i ~/.ssh_keypath/identityfile -p NN"
-i ~/.ssh_keypath/identityfile is the ssh keypath and identityfile and
-p NN is the port number ssh communicates through, default port 22
Ssh keypath and identityfile
How to set ssh keypath and identityfile in the user configuration.
If global ssh parameters are set, it applies to all configurations. It is possible to set other ssh values on each task. There is a check of the ssh keypath and identityfile. When enabling user selected ssh keypath and identityfile please make sure it is in compliance with:
The prefix has to be
~ followed by a
/. RsyncUI will verify that the ssh keypath is prefix by
~ and at least two
/ before saving the new keypath.
The following ssh tools are used:
ssh-copy-id. RsyncUI only assist in setting up RSA based key.
The ssh functions assist in two methods:
- private and public ssh key pair based upon default ssh values for RSA based key
- private and public ssh key pair based upon user selected values as
If creating a new public ssh key pair based upon default ssh values for RSA based key, RsyncUI does not add any parameters to the rsync command because this is default values. Ssh parameters to the rsync command is only added if the second method is chosen.
The following commands for creating a new, alternative private and public ssh key pair:
cd mkdir .ssh_rsyncosx ssh-keygen -t rsa -N "" -f ~/.ssh_rsyncosx/rsyncosx
-t rsa ""generates a RSA based key-pair
-N ""sets no password
~/.ssh_rsyncosx/rsyncosxis set by the user
The following command copy the newly created public key to the server:
ssh-copy-id -i /Users/thomas/.ssh_rsyncosx/rsyncosx -p NN user@server
You can also setup the new ssh keypath and identityfile in a terminal window and after setup add the new ssh keypath and identityfile in Userconfig. RsyncUI will automatically enable it when added in user config.
The user can also apply local ssh keypath and identityfile and ssh port, which rules the global settings, on each task.
Make sure that the new ssh catalog has the correct permissions. Open a terminal window and execute the following command.
chmod 700 ~/.ssh_rsyncosx
