3. Connect to it by double clicking, use the username `runneruser` with the password you just created. You should see the remote desktop window open.
## (For META Employees) Debugging using AWS SSM
AWS SSM can be used to log into _any_ currently running EC2 instances whether or not your SSH key has been added to the particular instance.
This can be used to debug currently running jobs on PRs or trunk.
### Pre-requisites
* Network connection on META VPN
* Cloud SSO Access (`bunnylol cloud fbossci`)
### Usage
```bash
aws ssm start-session --target "<instance_id>" --region "<region>"
```
Example:
```bash
aws ssm start-session --target i-0099d5a07d34e8904 --region us-east-1
```
### Caveats
* Nodes will still be reaped on their regular schedule
* Jobs will not wait for your session to finish before concluding
* There is no extra hold on the machine and the 2 hour timeout does not apply here, sessions will most likely end immediately at the next reap cycle
