I edit /etc/sysconfig/network-scripts/ifcfg-eth0 and add: DHCP_HOSTNAME=myhostname I edit it carefully, to preserve the hard links. I use emacs and set backup- by-copying-when-linked to t (IIRC). ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

NetworkManager-0.7.997-2.git20091214.fc12.x86_64 What you get in /var/run/nm-dhclient-ethX.conf during the DHCP request? That's where whatever is in the dhclient field should end up. It's there: send dhcp-client-identifier "myDHCPId"; # added by NetworkManager The dhcp server is dnsmasq, and sets up dns entries for the dhcp client id. It works for all my windows and mac systems. But none of my Linux systems work (all NM). My router (which runs dnsmasq) also shows a list of dhcp clients and their ids. Again, win/mac work but NM doesn't. What else should I check? Wireshark, to ensure that the client ID gets sent out on the wire. If it's in the config file, then that's where NM's sphere of influence stops (besides ensuring that NM gives the client the right config file, but that's easy enough to check for in /var/log/messages since NM prints out the command-line it's running dhclient with). Next, wireshark on the server to ensure that the DHCP request comes through correctly with the client ID. If it does, then dnsmasq is doing something badly... Dan Did you want DHCP_CLIENT_ID, or maybe you wanted DHCP_HOSTNAME? The latter is what I need (and nm doesn't seem to support) I want whichever one will make dnsmasq do the right thing and assign a dns entry for the device.
