VRkour is a service which runs a VR site.
Handed off to Jared Dunbar in late October
Basic Diagnosis
Basically, I rooted the VM and determined what was on it.
In bruskajp's home folder there's a file called start.sh and a folder called VRArena
To start the software, cd to that folder and then run 'npm start'. That will then start the stuff
Solution
I did a few things to make it operational again.
Systemd
First, I set up a systemd service
/etc/systemd/system/vrkour.service
[Unit] Description=vrkour [Service] User=bruskajp ExecStart=/bin/bash /home/bruskajp/start.sh Restart=always [Install] WantedBy=multi-user.target
Enable and start that service:
systemctl enable vrkour.service && systemctl start vrkour.service
Iptables Rules
Next, I added some iptables rules so that we can view port 3001 from 80 without privilege escalation.
So I added /etc/iptables.rules:
# Generated by iptables-save v1.4.21 on Wed Nov 2 17:27:10 2016 *nat :PREROUTING ACCEPT [2:130] :INPUT ACCEPT [2:130] :OUTPUT ACCEPT [1:96] :POSTROUTING ACCEPT [1:96] -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3001 COMMIT # Completed on Wed Nov 2 17:27:10 2016
and as well, we have a script in /etc/systemd/system/iptables.service, which loads that file.
The systemd service file reloads whenever it crashes. Apparently, according to James, crashing is a common problem.
