TS-7250-V3 Buster Network
From embeddedTS Manuals
The network in Debian is configured /etc/network/interfaces.d/. For complete documentation, see Debian's documentation here
Some common examples are shown below.
DHCP on eth0:
tee /etc/network/interfaces.d/eth0 <<'EOF' >/dev/null
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
EOF
Static IP on eth0:
tee /etc/network/interfaces.d/eth0 <<'EOF' >/dev/null
auto eth0
iface eth0 inet static
address 192.0.2.7/24
gateway 192.0.2.254
EOF
These will take effect on the next boot, or by restarting the networking service:
service networking restart
