I'm using Linode, and I've asked around on the IRC channels, but no one seems to know. I've logged into my server via LISH (reference), and I used the correct password, and everything went fine. However, I need to login via SSH/FTP, and I can't. It keeps on giving me "permission denied". I know the password is correct because I reset it via LISH, and I know I've got the login method right because I've logged into my server before using the exact same commands. I sure hope this doesn't turn out to be some noob issue, or I'm going to be quite frustrated.

You need to run ssh (the client, and possibly the server) with more verbosity to understand why authentication is failing. For the client, run

ssh -v -v -v username@host 

On the server end, look in the logs. /var/log/auth.log will give you a pretty good idea about what happens when you try to login, look for messages that contain "sshd". There are a variety of reasons why authentication could be failing, ranging from simple (you aren't using the right username) to more complicated (sshd is configured to use the wrong authentication system).

Thanks, I'll check that out as soon as I can get back to working on the server. –  willbeeler Mar 6 '12 at 19:32
    
I reset my password via the Web Console in Linode, and I was able to get back in. I appreciate the verbose tip. That's very useful. –  willbeeler Mar 9 '12 at 15:26
