I have recently started to configure my network using /etc/network/interfaces for a static IP address. For this I have added the following lines into the file:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.0.232
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 8.8.8.8 8.8.4.4
I have also changed managed=true in /etc/NetworkManager/NetworkManager.conf.
Everything works fine so far.
Today I realized that I have two identical default gateways (via a bash default gateway failover bash script that wouldn't work because of that reason).
Route shows the following:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
default 192.168.0.1 0.0.0.0 UG 100 0 0 eth0
link-local * 255.255.0.0 U 1000 0 0 eth0
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
The default gateway 192.168.0.1 shows up twice, once with metric 0 and once with 100. Is this the way it is supposed to be?
There are no files in /etc/NetworkManager/system-connections so I have no idea where that gateway is coming from. I don't have any scripts running that would add the gateway.
How do I remove one of them so it's gone permanently?
