David, How are your efforts toward setting a static IP address going? Have you succeeded.
I set up a lot of test servers (for fun and no profit), and hence work with Hypervisors (KVM more than Virtual Box), and have some experience in this area. But at this point I am not sure if you need assistance or were just generally asking questions about the comment in the documentation about dhcpcd. After checking my computers (VM and physical), I cannot find dhcpcd installed. Hence I guess the comment in the documentation was simply a reminder to anyone how may have been using that service, to ensure they disable it for their Static IP addressed interface? If you have having any challenges getting your VM to access your "UniFi equipment", please let me know. If the dhcpcd service was installed and running I presume: # systemctl stop dhcpcd.service will stop (deactivate) dhcpcd # systemctl disable dhcpcd.service will prevent it from restarting George. In my research before replying I found the following information which I found interesting. Thank you for raising your question. # systemctl list-units --type=service | grep dhcp https://wiki.debian.org/NetworkConfiguration Make sure to disable all DHCP services, e.g. dhcpcd. https://support.qacafe.com/cdrouter/knowledge-base/prevent-network-manager-from-controlling-an-interface/ The preferred way to tell Network Manager to stop controlling an interface is by creating/updating a file in the /etc/NetworkManager/conf.d/ directory and giving it the following content. You can name the file anything with a .conf suffix, but all files in that directory will be read in asciibetical order. Files read later override snippets of files read earlier. Make sure the keyfile plugin is listed. Other plugins may be listed too. [main] plugins=ifcfg-rh,keyfile [keyfile] unmanaged-devices=interface-name:eth0;interface-name:wifi1 The keyfile section can also include wildcards and exceptions as follows: [keyfile] unmanaged-devices=interface-name:eth*,except:interface-name:eth0,except:interface-name:eth3;interface-name:wifi* Interfaces can also be defined by their MAC addresses (in lower case): [keyfile] unmanaged-devices=mac:00:11:22:33:44:55;mac:66:77:88:99:00:aa Reboot for the changes to take effect. https://wiki.debian.org/NetworkConfiguration#Setting_up_an_Ethernet_Interface Gnome: sudo apt-get remove --purge network-manager-gnome network-manager network-manager-pptp network-manager-pptp-gnome KDE: sudo apt-get remove --purge knetworkmanager network-manager https://wiki.debian.org/SystemdNetworkd On Saturday, 06-07-2024 at 11:16 David Christensen wrote: > On 7/4/24 21:08, Felix Miata wrote: > <snip> > > On 7/4/24 21:10, jeremy ardley wrote: > <snip> > > On 7/5/24 11:44, Franco Martelli wrote: > <snip> > > > Thank you all for the replies. > > > I can find no statement in The Debian Administrator's Handbook regarding > disabling DHCP when using a static IP: > > https://www.debian.org/doc/manuals/debian-handbook/sect.network-config.en.html#sect.interface-ethernet > > > Similarly, when STFW "Debian 11 static IP" and reading articles. > > > Browsing the Debian Wiki page "NetworkConfiguration" -> "Info" link: > > https://wiki.debian.org/NetworkConfiguration?action=info > > The following sentence: > > "Make sure to disable all DHCP services, e.g. dhcpcd." > > Was added at revision 97: > > 97 2017-12-27 10:50:07 25741 to previous ?mrsgreen note > for static > ip's: disable dhcp services view > > > Who is "mrsgreen"? > > > David > >
