Well I've got a GoDaddy.com Virtual Server and this is the first time I've used linux for more than 10 minutes. I had been trying to figure out how to get the FTP server working (since their FAQ's answer to it wasn't very good and even following it exactly didn't work), in the process I believe I managed to prevent myself from logging in by SSH, I assume by setting /etc/hosts.deny to ALL: ALL or something similar. So I can't get in to change the file back, all I have access to right now is plesk, and I don't think I can replace the file from there (it doesn't show up in the file manager and attempting to create a new blank file of the same name gives an error).
After I submitted a trouble ticket they emailed me back saying since it's outside of their normal support scope they'd have to charge me $50 to go in and change that one file's contents... and if I'm wrong I'm out $50 and still can't access the server.
This is on Redhat 9.0 I believe, software on it after setup is as follows:
