Setting up a devotees dev box
-
Find EC2 in the "services" menu in the upper-left (Ubuntu 14.04 LTS for the base image; a
t2.micro
) -
In the network configuration, make sure that the
ssh
port 22 is open to the world for maximum insecurity (and so your pairing partners can connect). -
Name your new instance.
-
Set permissions to 0600:
chmod 0600 yourkey.pem
-
Store it somewhere safe!
- Grab the Public IP address from the EC2 console.
$ ssh -i yourkey.pem ubuntu@<public-ip>
- Set up the environment.
$ sudo apt-get update && sudo apt-get install tmux git vim irssi
- Run setup.sh to set up dotfiles. Type
reset ENTER
when you hit the bug.
$ sudo adduser <theirusername>
-
Give a terrible password so your pairing partner is motivated to change it.
-
Add them the sudo group
$ sudo usermod -aG sudo <theirusername>
- Now they can switch to sudo mode with
$ su - <theirusername>
-
sudo vim /etc/ssh/sshd_config
-
Change
PasswordAuthentication no
line toyes
. -
restart sshd:
sudo service ssh restart
-
Now your pairing partner can connect with
ssh <theirusername>@<public-ip>
.
-
By default tmux creates a non-shared session.
-
To allow sharing, use the
-S <socket-filename>
option with a file that will be accessible to other users. -
When creating a session for the first time, use
new -s
:
tmux -S /tmp/shared new -s <sessionname>
- Then within tmux, give permissions for your partner (and anyone else on this instance) to attach to your tmux socket:
chmod 0777 /tmp/shared
- For now, the owner of the devbox is the one who should create the session, until we figure out how to otherwise handle permission-management of folders like .ssh.
- First you need to ssh to the host's server like this:
ssh <theirusername>@<public-ip>
tmux -S /tmp/shared new -t <sessionname>
- Generate a new key
ssh-keygen -t rsa -C "[email protected]" -b 4096
- You will be prompted to name the key. Do not keep the default; rename it to your devotee handle. That way we can manage multiple keys for multiple accounts.
cat pub_key
- Add your public SSH key to gitlab, and then edit the config file in ~/.ssh/config.
