I executed the next command:
trytond - c /etc/tryton/trytond.conf -v
Then this is the error message:

I’m new with tryton and i read the documentation but i can’t get any answer for the error.
I will appreciate your help to resolve this problem.

including the content of your `/etc/tryton/trytond.conf`file could help. without it I could only shot in the dark.
the server address you used in the config file is unknown by the system (DNS resolution failed). So the server couldn’t bind to it and fail.
Review the [`web`](http://doc.tryton.org/projects/trytond/en/latest/topics/configuration.html#web) section of the config file. I think it is a problem with `listen` entry.

This looks like a DNS error. Make sure the names specified in your config file resolve correctly.

Thanks Sebastien and Nicolas
Now is running fine the trytond.
I need to change:
listen = \* :8000
by
listen = 192.168.1.15 :8000
Then is running
Now I need to upload the modules
Thanks again

Indeed if you want to listen to all interface, the right way is to use `0.0.0.0:8000` for IPv4 and `[::]:8000` for IPv6.
