    FWIW, you may want to cover installing a firewall to help lock down the server -- assuming the server is not a VPS run through OpenVZ (which sucks something terrible for game servers).
    I'd recommend covering the use of "ufw", as it's probably the simplest commandline frontend to iptables that I've seen.
    Just be sure to let people know to default in off, and always allow 22/tcp in. :)

    If you want to write it up, I'll happily add it.

    OK, so I'm new to Putty, Linux, computers, electricity, all this stuff... (Not really) But I need some help.

    I'm following your tutorial to the T, and I'm having problems. I'm doing everything as root. Do I need to create a user to do everything?

    Here's what I've done when I opened my server on Putty.

    Code:
    apt-get update
    I did this just to update my OS.

    Code:
    adduser minecraft
    I did this just to create a user so I don't run shit from root. I know to go back to root though if I'm downloading stuff like Java or Curl or WGET to my server.

    After that, I start following your tutorial!

    Code:
    sudo apt-get install openssh-server
    The output is

    Code:
    Reading package lists... Done
    Building dependency tree... Done
    openssh-server is already the newest version.
    
    OK, I can live with that... So, next I do this...

    Code:
    root@Gamingrepublic:~# sudo mkdir /opt/java
    
    It gives me NO output. If I ignore it and keep going with the steps, it outputs that I'm doing shit that it's not recognizing basically. I feel like I'm finger banging a tree right now.

    FWIW, "apt-get update" does not update the Linux operating system. It just obtains the latest package information.
    To fully update the OS on Ubuntu, you do this:
    Code:
    sudo apt-get update && apt-get upgrade
    It will list the packages it wants to update, and ask for confirmation to proceed.

    No worries. We are here to help.

    Yes, you should have a user created just for this purpose. I didn't cover that as its covered in the Ubuntu setup.

    That all looks good. You can run the server from the minecraft username you created.

    Good so far.

    When you first setup an Ubuntu Server 10.10 x64, it offers a bunch of things you can add. I skipped them all and clicked continue before I realized I should have chosen openssh. Hence I needed that command, but it looks like you don't.

    Type:
    Code:
    ls -lah /opt/
    
    The mkdir command gives you no output normally.

    OK, so I reinstalled my OS just to have a clean slate, and when I did I followed the instructions to install the openssh-server. Here's what it looks like...

    Code:
    root@Gamingrepublic:~# sudo apt-get install openssh-server
    Reading package lists... Done

       What would you like to do about it ?  Your options are:
        Y or I  : install the package maintainer's version
        N or O  : keep your currently-installed version
          D     : show the differences between the versions
          Z     : background this process to examine the situation
    The default action is to keep your current version.

    ssh stop/waiting

    I chose Y, should I have chosen N? Job failed to start. Is that a problem?

    Try this:

    "sudo service ssh start"

    If that doesn't work, replace "ssh" in the command with "sshd". I can't remember wtf the daemon was named.

    When? Before I run

    sudo apt-get install openssh-server

    ...or after all of the crap I just output'd, so now?

    Obsidian

    Yep, do it now and see if the ssh daemon starts up. I'd like to know what it says, it'll help me figure out what's going on with the installation (might just be a stupid warning being thrown).

    Job failed to start...strange.

    Googling around, it looks like a problem with the package "upstart".
    What distro are you using? (version too please)

    Ubuntu-10.04-x86_64

    I don't understand how others have had success getting it to start with the tutorial but I'm having problems.

    Sounds like you've got the botched upstart package. Can you try updating the OS and rebooting the server?

    Code:
    sudo apt-get update && apt-get upgrade -y
    
    # reboot command
    sudo reboot

    I just reinstalled my OS. When it comes back up, should I still do what you just suggested

    sudo apt-get update && apt-get upgrade -y
    # reboot command
    sudo reboot

    ?

    Obsidian

    Yep, do so. The server OS ISO you're using might have a borked package in there by default, and updating may help solve the problem.

    When I do the openssh command again and it asks me in the end if I want to update press Y or press N to keep as default config, what should I do?

    Hit D, find what's different. The new lines will be prefixed with a "+", the old lines prefixed with a "-".
    There might be something in the config that needs to stay the same. Hard to say without seeing the diff.

    Still updating...

    When I set the server up with craftbukkit, will this enable me to load my own personal world onto the server, or should I get another app/console for my server to do that?

    TnT Retired Staff

    Yes, you can do that.
    Why didn't you install 10.10 right away?

    Kid Tiger

    My hosting didn't offer it as an option. I don't know what's new and what's not, man.

    Like I said, it's updating still at the moment... as soon as it's done I'll jump back on the tutorial from step one and go forth.

    I'll adduser minecraft
    Then I'll go back to root and apt-get install openssh-server

    Is that a sound plan?

    @TnT I'm betting it's because 10.04 is an LTS release.

    At the start of the ubuntu 10.10 server install, what options did you choose?

    Kid Tiger

    Options? So far all I've done is reinstall my server and run the following command

    sudo apt-get update && apt-get upgrade -y

    It's still unpacking files and such...

    Ok, if you get an option to replace your ssh.conf file, don't do it.

    Now it's asking me about /etc/init/mountall.conf'

    I'm just choosing N for all of these...

    This is getting ridiculous. SERIOUSLY, do one of you want to set this up for me for a small fee? I've been dealing with this shit for 2 days. I'm over it. I just want it up and running now.

    Also, I just ran the command cat /etc/issue to see what ubuntu I had to make sure that I didn't sit through a 7 minute upgrade for nothing.. and lo and behold

    Code:
    root@Gamingrepublic:~# cat /etc/issue
    Ubuntu 10.04.2 LTS \n \l

    Yeah, you're not moving forward to a new OS when you update -- you're just updating the packages for it. Due to the nature of the dependencies, sometimes there are older packages in the previous repo that are necessary to not break everything in sight. The new releases of a distro usually have this resolved, but for an older release it's just not possible to set up without having massive dependency conflicts.
    Just take it easy, you're on the latest for that version of ubuntu now.



    Not to mention, it's an LTS (Long Term Release). It'll still get as new of packages as it can, and it's supported by canonical for 3 years, as opposed to the standard 18 months of support for the normal releases.
