[SOLVED] NetworkManager dhclient send host-name

Question

I use network-manager-applet on xfce4 . dhclient does not send the host name to the server. I don't see any related option in the applet.
dhclient is started without the "-H" option and the generated conf does not have a "send host-name" line.
"dhcp-client-identifier" is something different.
[il@vmarch ~]$ ps -Af | grep dhcp
root 548 185 0 12:01 ? 00:00:00 /usr/bin/dhclient -d -q -sf /usr/lib/networkmanager/nm-dhcp-helper -pf /var/run/dhclient-enp0s3.pid -lf /var/lib/NetworkManager/dhclient-eae8589b-41a8-4e9a-9bf1-29c0a43dc88a-enp0s3.lease -cf /var/lib/NetworkManager/dhclient-enp0s3.conf enp0s3
[il@vmarch ~]$ sudo cat /var/lib/NetworkManager/dhclient-enp0s3.conf

Answer 1

For some reason, NM does not use the host name obtained from OS.
Workaround:
[root@vmarch ~]# nmcli con show
NAME UUID TYPE DEVICE
enp0s3 84b17c75-9129-4944-849e-b82003511578 802-3-ethernet enp0s3
[root@vmarch ~]# nmcli con show enp0s3 | grep ipv4.dhcp-hostname
ipv4.dhcp-hostname: --
[root@vmarch ~]# nmcli con modify enp0s3 ipv4.dhcp-hostname `hostname`
