WHM API 1 Functions - create_remote_root_transfer_session

For more information about how this function works with other functions in the transfer and restore process, read our Guide to Transfer and Restore API Functions documentation.

Authentication

There are several methods that you can use to authenticate a transfer session with the remote server:

`PermitRootLogin=Yes`

The simplest authentication method is to use the root user and password. To do this, the sshd_config file on the remote server must contain the following value: PermitRootLogin=Yes

The following table displays the correct parameters and values for this authentication method:

Parameter	Value
`user`	`root`
`password`	`root`'s password

You can also use the SSH public key to authenticate the root user. If the SSH public key is encrypted, include the SSH key's passphrase.

The following table displays the correct parameters and values for this authentication method:

Parameter	Value if the SSH Key is not encrypted	Value if the SSH Key is encrypted
`user`	`root`	`root`
`sshkey_name`	The `root` user's SSH key.	The `root` user's SSH key.
`sshkey_passphrase`	(none)	The `root` user's SSH key passphrase.

`PermitRootLogin=No`

Many server administrators do not permit direct root logins on their servers.

If the remote server's sshd_config file contains PermitRootLogin=No, you must use another user and their password on the remote server, and then escalate to the root user.
If the system administrator used WHM's Manage Wheel Group Users interface (WHM >> Home >> Security Center >> Manage Wheel Group Users) to grant the user su access, then you will need to specify su and the root password.
If the user has sudo access, you do not need the root password.

The following table displays the correct parameters and values for this authentication method:

Parameter	Value if the user has `sudo` access	Value if the user has `su` access
`user`	The username.	The username.
`password`	The user's password.	The user's password.
`root_escalation_method`	`sudo`	`su`
`root_password`	(none)	The `root` user's password.

You can also use an SSH public key instead of a password to authenticate that user. If the SSH public key is encrypted, include the SSH key's passphrase.

The following table displays the correct parameters and values for this authentication method:

Parameter	`sudo`	`su`
`user`	The username.	The username.
`sshkey_name`	The user's SSH key.	The user's SSH key.
`sshkey_passphrase` (If encrypted)	The user's SSH key passphrase.	The user's SSH key passphrase.
`root_escalation_method`	`sudo`	`su`
`root_password`	(none)	The `root` user's password.
