Unauthorized access.

Error code: 3

Error message returned by the server: Permission denied

This is because you want administrator privileges, and you do not want to give normal users administrator privileges. so the root account is only used to upload files. Ubuntu does not open the root account by default, and we encourage the best not to use the root account of the direct operating system, the following steps to open the root account:

1. First set the root password

[Email protected]:~$ sudo passwd root

[sudo] password for Luban://Enter password for current normal user

Enter new UNIX Password://Set password for root

Retype new UNIX Password://Confirm Input Password

Passwd:password updated successfully

2. Modify the/etc/ssh/sshd_config file

[Email protected]:~$ su-root

Password:

[Email protected]:~# vi/etc/ssh/sshd_config

# Authentication: Logingracetime 120 # Permitrootlogin Without-password Permitrootlogin Yes Strictmodes Yes

Description: comment out "Permitrootlogin without-password" and add "permitrootlogin yes"

3. Restart the SSH service

[Email protected]:~# service SSH restart

SSH stop/waiting

SSH start/running, Process 1335

[Email protected]:~#

Once the operation is complete, you can log in to WINSCP via the root account.
