Please help me to access the SSH server

Is ssh service running in the server?
Any firewall blocking?

The ssh is working at the server, but I am not able to log in the SSH, and there is no firewall blocking. However, I logged in to the SSH today early morning, but it still keep asking me for security code, and I do not have the security code, nither the Amarican Company (Server provider) has the security code. Your help and support is highly appriecaited in this regard as soon as possible.

Do you know the username/password to login?
You told that you logged in but i think that you just been in login prompt.
If you do not know the username/pass or if you do not have RSA/DSA keys you can not login in the server.

The only way to get your SSH userid and password is to contact your VPS provider.
