Hello! Are there any plans for a Ajenti Version that runs on a raspberry. There are a few how tos online and the installation performs successfull, but the service will not start and there is no error msg or something. Only this :

Hi Adrian,


What happens when you try to access the panel? Any errors on the console / crashes?

Accessing the panel is not possible. The Server returns to the shell after the last debug msg.

This looks like architecture mismatch. Please replace python-gevent and python-greenlet with the versions from the corresponding raspbian repo. Let me know if this works.

Ok. I will try it tomorrow.

Hi Eugeny,


i replaced every python module with the versions from the rasbian repo or with the pip version and reinstalled ajenti after a full system cleanup. But without succsess. I got the same result:

strace ajenti-panel

I got it. It is the to old version of psutil. The rasbian repo version is 0.6.1. I upgrade with pip to version 1.1.2 an ajenti starts.

But there comes the next problem. stunnel4 and ajenti produce 100% cpu load and the webinterface need nearly 2 minutes to show up the login-screen.

Looks like a bad psutil module. Are you sure that you have installed python-psutil from raspbian? Other option is to run 'pip install psutil' - this will build a 100% native ARM psutil just for your Pi.

The pip Version works well. But the CPU Load is a problem. It took 1:56 Min until the loginscreen appears and another 2 and a half minutes until the dashboard is loaded. after that the performance is ok. Is there any option to speed up this a little bit ? 

I have poked around a bit and it seems that setting TCP_CORK significantly improves transfer speeds on low-end hardware.

Could you please either pull 'next' branch from git or add these 4 lines manually to ajenti/core.py?

Many thanks for testing!

Hello,
Just installed Ajenti on Raspberry Pi Model B+ and I can't get it working. I have python-psutil package. When I try to launch ajenti-panel I get this:

root@proc:/var/www# ajenti-panel -v
18.02.2015 21:01 ajenti-panel:105 INFO Using config file /etc/ajenti/config.json
18.02.2015 21:01 ajenti-panel:130 INFO Ajenti starting in foreground
Illegal instruction
root@proc:/var/www#

any ideas how to fix this? :)

That's typically caused by incorrect arch of packages with native extensions, i.e. python-gevent and python-greenlet
