Unsure about route configuration

Jump to solution

Hi,

after setup of a new subnet 192.168.3.0, I have problems getting the Galileo access to the internet.

When t type 'route', I see:

root@galileo:~# route

Kernel IP routing table

Destination Gateway Genmask Flags Metric Ref Use Iface

default 192.168.3.1 0.0.0.0 UG 0 0 0 enp0s20f6

192.168.2.1 192.168.3.1 255.255.255.255 UGH 0 0 0 enp0s20f6

192.168.3.0 * 255.255.255.0 U 0 0 0 enp0s20f6

192.168.3.1 * 255.255.255.255 UH 0 0 0 enp0s20f6

When I type 'ifconfig' I get:

root@galileo:~# ifconfig

enp0s20f6 Link encap:Ethernet HWaddr 98:4F:EE:05:13:94

inet addr:192.168.3.102 Bcast:192.168.3.255 Mask:255.255.255.0

RX bytes:18426 (17.9 KiB) TX bytes:18426 (17.9 KiB)

Not sure why the routing table still has 192.168.2.1 and how to setup the new subnet.

Hey Poseid - To delete your old route you'd run:

route del -net 192.168.2.1 gw 192.168.3.1 netmask 255.255.255.255

As for your current network issues, what are you having? Can you ping your gateway, if that works can you ping 8.8.8.8 ? If that works try pinging by name?

Cheers,

-Joe

Hi poseid,

Did you try with Joe's suggestion? Do you have access to Internet now?

Regards,

Charlie

Thanks for the help and sorry for the delay in response.

Joe's suggestion works!

But only ping 8.8.8.8 works, not ping google.com:

root@galileo:~# route

^C

Ok, last step is adding the DNS server with:

connmanctl> services

*AR Wired ethernet_984fee051394_cable

connmanctl>

root@galileo:~# connmanctl config ethernet_984fee051394_cable --nameservers 8.8.8.8 8.8.4.4

(hmm.. connmanctl is it on github? It would be nice to add some features to make it easier to use)
