I was stupid enough to set my password [via passwd] to

Well and since i also have been stupid enough to use root all the time without having a user acc I can't acces my server anymore. I have the option og recovering the pass through the hosting tech support, but I really don't want to resort to that since it costs money.

tl;dr Does my pass have any non allowed characters or is it too long or is something else wrong with it?

Yeah right like we're gonna know which character(s) are invalid! How do we know all of them are there? Or maybe there's too many there? We all have to pay for our mistakes, chalk this one up as a lesson learnt and ring tech support. There is a way to reset the root password, do a google search or a search in this forum.

Don't forget to setup a 'regular' user acct next time.

Yes there is a way to reset the password, but its ont a home PC, its a server and it doesnt allow me to mess with the boot.

Well, too bad its 11PM here, will have to wait a day.

Plus do you think it was wise to paste what is potentially your root password into a forum?? If I was you I would edit it out.

Yes, I do, since I changed a few parts of it, im using my junk-for-forum-registration email, im using a random generated username. I doubt anyone could find the IP of my server.

If that's the case then why use a password at all? What's to stop someone using what you've provided as a basis for a brute-force attack! Are you are the server admin? If that is the case, you should be more security conscious. You've already made one serious error by using just the root account. Never make assumptions. Just some friendly advice, nothing personal.

Let me change that, noone can find my server's IP from the data i have given away on this forum. Also im using linux for two weeks now, making mistakes isnt unussual.

This is true. All I am saying is doing things in a secure and structured way will minimise (the sometimes) devastating effects making mistakes can have on any system. Ok before this thread takes a potential turn for the worst, I propose we just leave it as is. I hope you get access to your server again. Peace.
