Try kill 18538; service ajenti start

I mean that you need -p in conjunction with all previous options, e.g. sudo netstat -tlnp | grep 8000

If you're running with -p, but don't see processes, add sudo.

Run netstat with -p to see which process took the port.

Have you used .m.css extension for your files? Only files with extensions marked as injected here: http://docs.ajenti.org/en/latest/dev/resources.html are combined into resources.css.

Here's an example CSS override for you: https://gist.github.com/Eugeny/2049b75306af4234add5

I released an update which adds a "custom local router config", which gets appended to all local inbound router configs.

Hi Gary,

I suggest that you start with source checkout of Ajenti first (instead of modifying an installed package): http://docs.ajenti.org/en/latest/dev/intro.html
Note the requirement for CoffeeScript and LESS compilers. There's actually a resource build involved, which can be done by running make.

If you want to just quickly customize looks for your deployment, it's better to create a plugin which bundles your JS/CSS. 
See the docs (updated) here: http://docs.ajenti.org/en/latest/dev/intro.html and here: http://docs.ajenti.org/en/latest/dev/resources.htm...

P.S. if you would like to fully remove "Ajenti" brand from the panel (white-label), you need to hold one of the commercial licenses.

You can put it into Mail > Advanced > Custom configuration ;)
