All I have in /etc/network/interfaces.d/interfaces is: # The loopback network interface auto lo iface lo inet loopback For my desktop computer, in Network Manager, for my SSID in IPV4 settings: Address: 192.169.1.215 Netmask: 24 Gateway: 192.168.254 Of course your actual machine address and gateway address will vary. I do also assign my network's static IPs and corresponding MAC addresses in my Router's Static ARP table. In general anything fixed at home (desktop, mail server, printer, smart tvs, chromecast, roku, WAP, etc) has a static IP and portable devices (phones, tablets, cameras, etc) has a dynamic IP. -- Marjorie ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Arrgh! that command chain doesn't (distinguish between what is and isn't installed) work right.

Re: [DNG] Refracta have a static IP
..could this be as simple as: address 192.168.0.199/24 #??? Yes No, in /etc/network/interfaces it needs a net mask line like this : auto eth0 iface eth0 inet static address 192.168.nnn.nnn netmask 255.255.255.0 gateway 192.168.nnn.nnn No RTFM? Documentation states, for both INET & INET6 families: address address Address (dotted quad/netmask) required netmask mask Netmask (dotted quad or number of bits) deprecated Are we really debating how to configure network addresses without first searching in the man pages? I hope no-one is giving speeches in the whole lot :oP The only things which are not documented in the "interfaces" man page is how the default value for optional directives is computed. In doubt, specify those, but they are technically not required. Welcome to "default values" wonderland.

..many ways: https://duckduckgo.com/?q=Devuan+fixed+ip+on+dhcp&ia=web
or https://duckduckgo.com/?q=Devuan+static+ip+on+dhcp&ia=web all shows
various ways to set up your dhcp client to request a specific ip, or
have your dhcp server deliver a specific ip address to a specific mac
address on that dhcp client. Etc.
..note that any of those servers or clients on your lan "may have"
caches or cached settings that you "may" wanna clean out. ;o)
..also, if you haven't set up ipv6, that too might mess up your lan.
..your problem looks quite a bit like:
https://unix.stackexchange.com/questions/85047/losing-static-ip-and-and-getting-dhcp-ip
..e.g. /etc/dhcpcd.conf from link above:
# /etc/dhcpcd.conf
# to stop all my NICs from getting the DHCP address
# above any configured interface: (I am using 2 NICs
# both set at eth0 and eth1)
denyinterfaces eth0 eth1
...and #: /etc/init.d/networking restart
..a neater way, once everything works ok:
https://www.linuxquestions.org/questions/linux-networking-3/alternating-between-dhcp-and-a-static-address-depending-on-availability-4175676466/
..the classic way, way down: https://tldp.org/HOWTO/DHCP/x74.html
at: 3.11. Alternative DHCP client (ISC dhclient):
...create a /etc/dhclient.conf file with this example configuration.
interface "eth0" {
send dhcp-client-identifier 1:xx:xx:xx:xx:xx:xx;
# send dhcp-lease-time 86400;
}
Here we assume that the ethernet interface is eth0. If not change
accordingly. Also replace xx:xx:xx:xx:xx with your ethernet address."
..classic serverside way: https://tldp.org/HOWTO/DHCP/x369.html where
you want: "You can also assign specific IP addresses based on clients
ethernet address e.g.
host haagen {
hardware ethernet 08:00:2b:4c:59:23;
fixed-address 192.168.1.222;
}
This will assign IP address 192.168.1.222 to a client with ethernet
address 08:00:2b:4c:59:23."
..nd, I found out why I found myself searching for "fixed",
rather than "static." ;o)
