I am trying to start arachni_web automatically after reboot on my Debian 9 server but can't seem to make it work.

I created the file arachni-web.service in /etc/systemd/system:

[Unit]
Description=Arachni Web UI
After=network.target

[Service]
Type=simple
ExecStart=/arachni/bin/arachni_web -D -o 1.1.1.1
Restart=always

[Install]
WantedBy=multi-user.target

To test, I can see the service started:

$ sudo systemctl start arachni-web.service
$ sudo systemctl list-units -t service --all | grep arachni
  arachni-web.service                  loaded    active   running Arachni Web UI

The process is running:

$ ps -ef | grep arachni
root      4573     1 99 17:34 ?        00:00:03 ruby /arachni/bin/../system/gems/bin/rackup /arachni/bin/../system/arachni-ui-web/config.ru -D -o 1.1.1.1

But when I do a netstat -plnt, it is not listening on 9292. I can't connect using my web browser as well.

$ sudo netstat -plnt
[sudo] password for arachni:

Any ideas?

   Just for kicks, if you run /arachni/bin/arachni_web -D -o 1.1.1.1 without the service, does the application UI appear? If so, my gut is leaning towards a daemon/user permissions issue, but that's just a guess.

   Yes, the web UI appears.

   Permissions:
   

   $ ls -l /etc/systemd/system
   total 32
   -rwxr-xr-x 1 root root  185 Feb 10 17:34 arachni-web.service
   
   
   
   
   $ ls -l /arachni/bin
   total 80
   -rwxr-xr-x 1 arachni arachni 389 Mar 29  2017 arachni_web
   

   Am I missing something?

   Admittedly systemd or initd setup is not my area of expertise. However, if you're able to run the exact same command as the service but when you invoke the service it works, I'm inclined to think of the issue as one of two things:

   1) Permissions: Does the daemon running the service have the permissions that it needs?
   2) Race Condition: Are there dependencies that are available once the system is fully booted that might not be available when the systemd or initd service is called?
