WinSCP connects to Ubuntu. Access closed

I installed Ubuntu13_desktop on VMware (VMware® Workstation 7.1.6) based on Windows 7. Now I want to connect to Ubuntu from Windows 7. Install WMware as Host Only . Installed WinSCP on Windows, configured

protocol: SFTP; Host name: ubuntu; Port: 22; UserName: oracle; Password: ***.

Click login, it showed

 Searching for host... Connection to host... Authenticating... Using username "oracle" Authenticating with pre-entered password. Access denied. Access denied.

I will be able to ping Ubuntu using cmd.

Can someone help me to allow me access to Ubuntu using WinSCP? Thanks in advance.

Well, port 22 is for SSH service. Therefore, you can probably try installing the openssh server in your ubuntu by typing

sudo apt-get install openssh-server

and then try connecting with the following data:

: Ssh

host name: [computer IP address]

port: 22

username: [username]

password: [password]

Hope this should work.

First look at auth.log on the system.

 cat /var/log/auth.log

In my case with WinSCP, I found something like this:

 fatal: no matching mac found: client hmac-sha1,hmac-sha1-96,hmac-md5 server hmac-sha2-512,hmac-sha2-256,hmac-ripemd160 [preauth]

And comment out the line in /etc/ssh/sshd_config :

 MACs hmac-sha2-512,hmac-sha2-256,hmac-ripemd160

don't forget to restart ssh :-) Hope this helps someone.

If sshd (openssh-server) is installed and running, but when using WinSCP, there is still no access. In Ubuntu 16.x, view auth logs:

 sudo cat /var/log/auth.log

I found this:

 No supported authentication methods available [preauth]

The problem is setting Ubuntu sshd by default to authenticate public / private key for ssh remote access:

 RSAAuthentication yes PubkeyAuthentication yes PasswordAuthentication no

If you want to skip kay-pair, open the conf sshd file:

 sudo nano /etc/ssh/sshd_config

Find the above attributes and change to:

 RSAAuthentication no PubkeyAuthentication no PasswordAuthentication yes

restart sshd:

 sudo systemctl restart sshd

If you configured the user on an instance of Ubuntu 16.x, you should now be able to use ssh or WinSCP with username / password. Keep in mind that system security is now at greater risk.
