Ubuntu server SSH access denied

[Joveice]

Hi, I'm having issues connecting to my server with SSH, I know the password is right becouse it works from the computer itself. tho it throws access denied after I enter a password.

What is this and how do I fix this?

I use PuTTY to connect.

Are you trying to login as root? You normally can't ssh as root.

No I'm trying to connect as the user I setup when I installed (this works on my second server)

did you allow the user in the ssh config?

Dident do this before, and if it's the /etc/ssh/ssh_config and by doing AllowUsers "username" then yes I did that and I restarted ssh after that.

Don't have any other users, just installed the server.

Do you have console access? Does the VPS provider have any options to log in via console (RamNode provides such feature, for example)?
Have you set up SSH keys maybe, that you could use to log in without password?

It's a physics server, so I got physics access.

Enabled cleartext logins?

[TidaLWaveZ]

You must enable cleartext password logins. These are disabled by default in Ubuntu (except for root, because by default root has a disabled login and can only be accessed via sudo elevation)

If you are running the desktop version of Ubuntu you must first install `openssh-server`.

Edit /etc/ssh/sshd_config

scroll down to the line `#PasswordAuthentication yes` and remove the # symbol. Save the file and restart the `ssh` service by typing `sudo service ssh restart`

You should be good to go.

However, a better approach is to create a public-private keypair which can be used for authentication. That's the preferred way to perform remote logins as multiple individuals can be granted access to a single user account without revealing their private keys

Well I typed my password in the username field to check if there was some keyboard layout things but no, the password was correct and physics access does work.

No one else that has an idea?

Seem to have found the issue, tryed to SSH into the server while it was installing updates (dident install openssh-server this time) and there the prompt was. so I guessed the default password logins for ikvm, and there I was in SMASH. how can I fix this? I want to ssh to my linux not to the server itself ? Motherboard is ASUS Z10PE-D16 WS

This is a bit confusing, so you are able to login to the server over the KVM console but not SSH? Did you check to make sure there were no iptables rules blocking you ("iptables -F"). Can you check the logs to see what it's saying when you try to SSH into the server?

The logs for the ssh are emtpy, and I havent checked iptables, but I'm gonna try change the port to something else, then try that and see if that works.

Edit: Forgot to answer the first question, Well I don't know what SSH I got into, just that the default password I used to connect to the ikvm and view the screen worked on the ssh connection, then it gave me a "sql" looking terminal that said SMASH or something like that.

If it's a firewall issue (iptables) then changing the port won't help. Can you run this command and post the output?

netstat -tulp | grep ssh
