SSH connection using transfer

I am try to use the transfer tool. The session ends and I am not connecting to the server. I tried connecting using Putty to see if I could connect successfully. I sign in with my user name and it asks for password. After I enter it, Putty closes with no error. If I try the password incorrect, it will say incorrect password. I added my username to the wheel group.

  The remote basic credential check failed due to an error (The system failed to escalate privileges to root on "xxx.xx.xx.xx" with "sudo" or "su" because of an error: Failed to escalate to root) and response: Connecting to xxx.xx.xx.xx as myname...using method password...Connection Success Waiting for login prompt ....Waiting for login prompt timed out, assuming the shell has an odd prompt.

  So does this mean it has connected? The message just cuts off and doesn't tell me what happens. Should i be using a key? In WHM is shows there is a public and privite key names id_rsa. Password Authentication is currently enabled. Is there anything else I can check?

  I tried using Putty and SSH to connect to my new server and it worked. So I know its not a firewall, port or Putty issue. But this might help solve the problem. When I first open Putty it mentioned the key being save to cache. But I said no. On the other server that doesnt connect, the terminal says "using keyboard-interactive authentication" password: There is a key on the old server called id_rsa. Should I try and delete that?

  I tried using the terminal in WHM and looked at the logs # tail -f -n 50 /var/log/secure | grep sshd pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=xxx.xxx.xx.xx user=myname error: PAM: Authentication failure for myname from xxx.xxx.xx.xx Accepted keyboard-interactive/pam for myname from xxx.xxx.xx.xx port 58783 ssh2 pam_unix(sshd:session): session opened for user myname by (uid=0) pam_unix(sshd:session): session closed for user myname One thing I noticed was this line in the config file. It doesn't say yes or no because its commented out. vi /etc/ssh/sshd_config # Authentication: #PermitRootLogin yes My new server that I can log in reads like this: PermitRootLogin no

  I contacted my service provider of my VPS. They recommended repairing or reinstalling SSH. Does that sound like a possible fix?

  What is the output of the following on both servers? grep PasswordAuthentication /etc/ssh/sshd_config

  On both servers it says: #PasswordAuthentication yes PasswordAuthentication yes # PasswordAuthentication. Depending on your PAM configuration, # PAM authentication, then enable this but set PasswordAuthentication

  I'm not entirely sure what it is you're trying to achieve, however I use putty to upload my internal backups to our WHM server, using a batch file, if this helps. This is the command I use: psftp user@111.222.333.444 -pw password -P 22 -b script.txt then my script.txt says: put myfile.rar I've obscured my sensitive info along with the actual port I use

  Based on that it looks like root login isn't permitted, I don't know what user you're attempting to log in as since you've not disclosed that Based on the fact you noted you are using puTTY it does have a log file Putty - Automatically closes on authentication
