Hello all,  
after the installation of cells I get a bunch of open ports e.g. :::34113 :::38557 ans so on all IPV6.  
Can anyone point me to the docs where this ports are explained?  
Furthermore if this ports have to be open, I want to bind them to localhost but can’t find the config for this ☹

Thanks in advance  
Holger

Hi,  
i think you should find informations about that, here [https://pydio.com/en/docs/developer-guide/cells-internals](https://pydio.com/en/docs/developer-guide/cells-internals), the ports chosen are random.

Hi Zayn,

thanks for that. Do you know where in the docs I can find the information how to bind the randomly choosen ports to localhost instead of all?

Hi,  
what did you choose for the internal\_url during installation?

Hello,  
in that case it was it’s private IP 192.168.211.121 Port was 8085.  
So internal\_url was [http://192.168.211.121:8085](http://192.168.211.121:8085)
