Hi,
My configuration in /etc/oidentd.conf is:

`default {

    default {
            allow spoof
            deny spoof_all
            deny spoof_privport
            allow random
            allow random_numeric
            allow numeric
            allow hide
    }

} `

My file .oidentd.conf location is ~/.oidentd.conf and permission is -rw-r--r-- (644) ans
My $HOME direction permission is drwxr-xr-x

The configuration os setfile is the same ~/.oidentd.conf and setformat is global { reply "%user%" }

The message in the server irc is No ident response; username prefixed with ~
I have this same configuration in other vps and work. I do not know what is a problem. Cloud you help me?

Per https://wiki.znc.in/Identfile#Using_identfile_with_oidentd the /etc/oidentd.conf needs to contain

user "znc" {
    default {
        allow spoof
        allow spoof_all
    }
}

as the default {} block is insufficient by itself. Replace "znc" with the name if the system user running the ZNC instance.

I appreciate your help.
I had already switched to this configuration that you suggested, but it didn't work. But I changed now again, it didn't work again. I want to mention that my znc is running with my username and not with "znc" username. The configuration that i put now, was

user "myuser" { default { allow spoof allow spoof_all } }

default { default { allow spoof deny spoof_all deny spoof_privport allow random allow random_numeric allow numeric allow hide } }
but does not work.

The oidentd daemon needs to be restarted when you edit the oidentd.conf file, and you need to make sure port 113 is accessible remotely.

Yes,
I restaed daemon oidentd with command sudo systemctl restart oidentd and my port 113 is open. I make command netstat -anp | grep 113 and have the response:

tcp 0 0 0.0.0.0:113 0.0.0.0:* LISTEN 24094/oidentd
tcp6 0 0 :::113 :::* LISTEN 24094/oidentd

I already restart znc and even so, does not work.

Just because a port is being listened on doesn't mean it's accessible .. you even quoted "No ident response; username prefixed with ~" which means port 113 isn't open. Check your firewall rules.

Ok. Work now. Was the port 113 that still close.
I guess that I had opened.
Thank you so much even.
