[Sidius]

Hello

I need make a persistent route of subnet 10.0.0.0/24 to host 192.168.0.200 via eth0 in my new debian 12 lxc container and i cannot (

i tried to edit /etc/network/interfaces file with

auto eth0
iface eth0 inet static
        address 192.168.0.100/24
        down route del 10.0.0.0/24 via 192.168.0.200 dev eth0
        up route add 10.0.0.0/24 via 192.168.0.200 dev eth0

when i do systemctl restart networking it returns
Job for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xeu networking.service" for details.

Hi,

down route del 10.0.0.0/24 via 192.168.0.200 dev eth0
up route add 10.0.0.0/24 via 192.168.0.200 dev eth0

these lines should read

down ip route del 10.0.0.0/24 via 192.168.0.200 dev eth0
up ip route add 10.0.0.0/24 via 192.168.0.200 dev eth0

since ip route is the actual command you are trying to use.

when i do systemctl restart networking it returns
Job for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xeu networking.service" for details.

Also, it is always helpful to provide all the error messages - in this case, running journalctl -xeu networking.service would have probably revealed that it fails to run the route command, since it probably does not exist.

Nothing special there (if so, i've fixed problem by myself)

# journalctl -xeu networking.service

Maybe i need to restart CT to apply changes? If i do systemctl restart networking with default /etc/network/interfaces - it returns the same error.
