Hi all

I am pretty new to linux and VPS so apologies up front. I am trying to set up a ubooquity server on my DO VPS. I have successfully installed the latest version using this workflow:

  • install java8
  • download ubooquity with wget, unzip to /opt/ubooquity
  • run headless to test in cmd - works (but I can not connect)
  • add ubooquity to init.d to start at boot

Also succesfully installed and set up Amazon Cloud Drive access via FUSE

  • install acd_cli via cl
  • set up and auth using acdcli init / acdcli sync
  • set up permanent mount using crontab @ reboot

Reboot droplet to test everything, all working (acd_cli mounts on reboot, ubooquity service is running (sudo service ubooquity status > Ubooquity is running...)

I have checked that i have opened correct port in ufw via
sudo netstat -plunt - port specified in ubooquity preferences.xml is listed as open

However when I try to go to http//:dropletip:port/admin i get a 404...

Used bits and pieces form these guides to get this far.
Install Ubooquity...
How To Set Up a Firewall with UFW on Ubuntu 14.04
How to access Amazon Cloud Drive from the command line on Linux

Any tricks I need to do on a more general level to gain external access? After I get direct access I was going to install inadyn and set up DDNS.

The 404 seems to suggest that it's running, but I'm not sure what to directly suggest as I cannot replicate the matter. I have run through the guide provided twice now and it runs without any issue. You may wish to start again, ensuring you have not made any mistakes.

The 404 means that it is connecting, so I would rule out the firewall, and limit it to something with Ubooquity directly. I would recommend running it from the command line, not using the init script and checking for any error or warning output.

So I would suggest running it with sudo java -jar /opt/ubooquity/Ubooquity.jar -webadmin -headless -port 2022 (You might have to shut down the service if you have it setup already, and then trying to connect. Hopefully it will give some warning or error to help point to the actual cause.

Sorry I cannot offer more direct advice, but I cannot replicate the issue you are having, so it's hard to say what the issue is.
