Ajenti Port Not Working on Debian

Posted February 17, 2016 8.9k views

I installed Ajenti using http://support.ajenti.org/topic/349864-installing-on-debian/. Everything looks okay from the ssh, it says; 

:: Done! Open https://<address>:8000 in browser

When I open it in Chrome, I get: 

No data received - ERR_EMPTY_RESPONSE

Also, when I try Debian’s debug, ajenti-panel -v, I get:

ERROR Could not bind to (u'0.0.0.0', 8000)

After checking on if there is something else listening to the port, I find Python. I’ve tried killing Python and the process dies, but I still cannot get Ajenti to work. The only thing I have installed now are the basic LAMP stuff (apache, mysql, etc).

Any help would be great! :)

When running ajenti-panel -v the Python process that is already bound to the port is Ajenti itself. First, stop the Ajenti service with:

  • service ajenti stop

Now, when you run ajenti-panel -v, you will see the real problem. Here’s the Python Traceback:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/gevent/greenlet.py", line 327, in run
    result = self._run(*self.args, **self.kwargs)

There is a report on Ajenti’s GitHub issue tracker about this: https://github.com/ajenti/ajenti/issues/702

In a fresh Debian 8 (Jessie) install, Ajenti would timeout when I tried to connect through HTTP.

I only had to disable SSL in the new /etc/ajenti/config.yml to get it working. But it’s simpler (and more secure) to use HTTPS, and that worked out-of-the-box.
