tl;dr
Paste this one line into your server console
ssh-import-id-gh pfaffman
and send me the user you log in as (usually root
or ubuntu
) and your IP address or hostname.
If you need to open an ssh port for me to connect, my IP address is 154.9.154.67
.
Longer version with more details
If you have installed Discourse yourself and want to give me access to your server, here’s what to do.
First, you will need to connect to a shell on your server via ssh
or the Digital Ocean console or something similar. If you have ever typed something like cd /var/discourse;./launcher rebuild app
, you need to do whatever you do to get there. Then you’ll paste (or even type!) the command below.
Simple case using something like Ubuntu on Digital Ocean with username root
or ubuntu
If you are using Ubuntu, you should be able to log in via SSH, or connect via the Digital Ocean console and paste in this command:
ssh-import-id-gh pfaffman
You should see a few lines of text that ends with something like “SSH keys [Authorized]
”
That’s the best way, as it will see that authorized_keys
is created with the correct permissions.
That should do it, but if you got something that looked like an error, you may need to keep going.
If you’re not using a recent version of Ubuntu
If that fails for some reason, this should work:
curl https://github.com/pfaffman.keys >> ~/.ssh/authorized_keys
If that fails, then your .ssh
directgory doesn’t exist. An easy way to fix that is to create your own key with
ssh-keygen
and hit return a few times. That will generate a key (which I don’t need) and also see that ~/.ssh is created with the correct permissions. Then go back and use the curl
command above.
If your username is not root
or ubuntu
I need the username
After you have added my key, all I need to know is the hostname (or IP address) and the username. I’ll try root
, and ubuntu
if you don’t give me one.
sudo access is also required
For most setups, the user that you use (e.g., root
or ubuntu
) has super user privileges, but if you add a user just for me, please see that the user can use sudo
without a password. You can do that like this:
sudo su -c 'echo =username= ALL = NOPASSWD: ALL > /etc/sudoers.d/=username=' root
If the user you created was not pfaffman
, please substitute accordingly.
If you use Cloudflare, reverse proxy, or a load balancer
If you are using Cloudflare or something else that makes your forum’s domain name not be the same as the name/IP address to use for ssh access, I will need that IP address or hostname for the virtual machine.
If you want to limit ssh access, Literate Computing will be connecting from 154.9.154.67.
