 Posted: Mon May 14, 2018 7:26 pm Post subject: Questions about Iproute2 |
 |
|
Hi Guys
Whats the Iproute2 equivalent for this route command?
| Code: | | route add default gw 192.168.0.1 wlan0 |
I read some examples and tutorials but they dont work as example:
| Code: | | ip route add default via 192.168.0.1 dev wlan0 |
But like i said, it doesn't work:
| Code: | root@omv:~# ip route add default via 192.168.0.1 dev wlan0
RTNETLINK answers: No such process
root@omv:~#
|
Can someone explain me the correct command? |

Not working ----> RTNETLINK answers: File exist
Here is my complete output:
| Code: | root@omv:~# route -n

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0

| Code: |
root@omv:~# ip route add 192.168.0.0/24 via 192.168.0.1
RTNETLINK answers: File exists

| Code: | root@omv:~# ip route show

192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.10
192.168.0.0/24 dev wlan0 proto kernel scope link src 192.168.0.11
root@omv:~# ip route del 192.168.0.0/24 via 192.168.0.1
RTNETLINK answers: No such process

| Code: |
root@omv:~# ip route show
default via 192.168.0.1 dev eth0
192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.10
192.168.0.0/24 dev wlan0 proto kernel scope link src 192.168.0.11

But "route add default gw 192.168.0.1 wlan0" works... 
| Code: | root@omv:~# route -n
Kernel-IP-Routentabelle

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0

192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0

PyCoder ...
is wasn't clear from your initial description you wanted two "default" routes. The reason it's "default" is that, as the name suggests, this is a singular parameter for a given system, it can be done (see here and here) but I don't think you actually want this (because from the above it seems they both point to that one gateway). So, why do you think you need this?

My problem is... i have eth0 and wlan0 but wlan0 is not able to ping something outside of my lan e.g. google.com
I posted my problem here: https://forum.openmediavault.org/index.php/Thread/22875-Wifi-wlan0-not-working-outside-of-my-LAN/?postID=174896#post174896
But no1 could help me, so i decided to ask my old trusty gentoo boys 
I know the Thomas Krenn Howto but its not working ether ---> same error msg (file exists or ressource not found) |

you could add routes_wlan0="default via 192.168.0.1" in /etc/conf.d/net
or you could bridge the two interface and use the bridge route to reach the gw (see https://wiki.gentoo.org/wiki/Network_bridge)
And you should also have a default route for localhost, something you are lacking. Do you lack loopback init.d service in boot runlevel?
And the error "file exist" is just telling you that this route is already create, so it doesn't work because the route exists, but the command do works. |

PyCoder,
Two interfaces in the same subnet is usually a very bad thing.
Tell us what you want to achieve.
iproute2 tries to protect you from yourself a little more than the route command.

Moved from Networking & Security to Unsupported Software. OP is apparently running OpenMediaVault, not Gentoo, so it fits better here.
