XRDP Remote Desktop (Also installs SSH and some utility packages)

cd Downloads
git clone https://gitlab.com/johanvandegriff/zfs-server-cluster-setup
cd zfs-server-cluster-setup
sudo bash ubuntu-xrdp-only.sh

after the script ends, reboot (as instructed by a message at the end)

SSH Server (don’t need to do this if you ran the XRDP script above)

sudo apt install openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd

SSH Tunnelling

https://gitlab.com/johanvandegriff/ssh-tunnel-manager

cd
git clone https://gitlab.com/johanvandegriff/ssh-tunnel-manager.git
cd ssh-tunnel-manager
./no-root-setup.sh

The script asks for several values: URL or IP address: umd-aimar.com SSH port of remote server: 22 Username of the account for forwarding: teamaimar Name of the SSH key: umd-aimar SSH port of local machine: 22

a workaround for a problem with ssh configs

ssh [email protected] 'cat .ssh/config.d/aimar  >> .ssh/config'

optional: add ssh key from umd-aimar.com to the lab computer

ssh [email protected]
$ ssh-keygen -b 4096 -N "" -f /home/teamaimar/.ssh/lab_computer
$ cat "/home/teamaimar/.ssh/lab_computer.pub" | ssh aimar "cat >> /home/team/.ssh/authorized_keys"
$ echo '        IdentityFile /home/teamaimar/.ssh/lab_computer' >> .ssh/config

to access the lab computer from anywhere:

ssh -t [email protected] ssh aimar

Note: the old setup was more manual and ended up with the command:

ssh -t [email protected] ssh lab

That old setup is still in place, so either command should work until we reinstall

Upload IP Address to Slack

https://gitlab.com/johanvandegriff/slack-upload-ip

cd
git clone https://gitlab.com/johanvandegriff/slack-upload-ip.git
cd slack-upload-ip
./slack-upload-ip.sh --setup

it asks for the webhook URL. Follow this guide to generate one. The script has set up a cron job to run every 5 minutes to check if the IP address has changed, and if it has, send a message to slack. So you should get a message at the next increment of 5 minutes (on the hour, 5 past, 10 past, etc.). Bootup Message in Slack

cd ~/slack-upload-ip
sudo ./bootup-ip.sh --setup

This script will run on startup and post a message to the slack telling that it booted up, what IP address it has, and what network it is connected to.
