route shows two default paths - how to remove one?


'route' shows me:

Destination Gateway Genmask Flags Metric Ref Use Iface
localnet * U 0 0 0 eth0
localnet * U 0 0 0 eth1
localnet * U 0 0 0 wlan0
loopback * U 0 0 0 lo
default UG 0 0 0 wlan0
default UG 1 0 0 eth0

How can I bet permanently remove eth0 as a default?

Delete default gw

route del default gw

Delete gw for network
route del -net gw

route del eth0

If you are using Debian then remove it from config file /etc/network/interfaces, look for line such as follows:

Hope this helps read man page of route for more info and examples

I tried: route del default dev eth0

But when next I boot up Linux, the removed default path is back. I want to remove this path as when I ping my router on, I get host unreachable:

PING ( 56(84) bytes of data.
From icmp_seq=1 Destination Host Unreachable
From icmp_seq=2 Destination Host Unreachable
From icmp_seq=3 Destination Host Unreachable
From icmp_seq=5 Destination Host Unreachable
From icmp_seq=6 Destination Host Unreachable
From icmp_seq=7 Destination Host Unreachable

Interestingly, .106 is the IP address I assigned to my eth0 NIC. This why I want to remove this path. However, AFTER executing 'route del default dev eth0', I still get the same PING error.

Only when I do 'ifconfig eth0 down' do I get the successful ping, i.e. a ping from .102.

This is not what I want to have to do however - I want all my devices up (and wlan0 on .102 as default). How do I manage this?

Many thanks for any further pointers...

Check your /etc/sysconfig/network-scripts/ifcfg-eth0 file. if you find Gatway entry init, Remove that entry. just specified gatway entry in /etc/sysconfig/network. you might have entry in each of your ethXXX file in network-scripts and also in network file.

I don't have those files/folders, under Slackware 10.2.

I have sorted things by properly configuring /etc/rc.d/rc.inet1.conf, using dhcp on all NICs and assigning the IP addresses I need with DHCP_IPADDR[x]=.

The only problem now is that Linux pauses for an age when trying to DHCPCD eth0, since eth0 is not connected (but is from time to time, hence why I want it there), before progressing to DHCPCD wlan0.

Cheers - Steven.
