 Posted: Sat Aug 13, 2011 9:08 am Post subject: Multiple default gateways |
 |
|
Hi Folks
Since upgrading to baselayout-2, I now have multiple default gateways in my routing table, on a single wired ethernet connection...
| Code: | thinkpad ~ # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.0.200 0.0.0.0 UG 0 0 0 eth0
0.0.0.0 192.168.0.200 0.0.0.0 UG 2 0 0 eth0
0.0.0.0 192.168.0.200 0.0.0.0 UG 202 0 0 eth0 |
Sure, I can zap the extra ones...
| Code: | thinkpad ~ # route del default netmask 0.0.0.0 metric 202 dev eth0
thinkpad ~ # route del default netmask 0.0.0.0 metric 2 dev eth0 |
...to leave me with what I had before baselayout2...
| Code: | Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.0.200 0.0.0.0 UG 0 0 0 eth0 |
...but why I have I got these in the first place?!
Here is my /etc/conf.d/net which is using DHCP...
...and this occurs on any network I join, work or friends.
Thanks.
Paully

Hi,
could you post your /etc/conf.d/net file ?
I think you might have something like : routes_eth0="default gw 192.168.0.200..etc"

You can CTRL-C the dhcpcd process once you've colleted the data and just restart it with
dhcpcd |
OK...

dhcpcd[3379]: forked to background, child pid 3442 |
My routing table now reads...
| Code: | thinkpad ~ # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.1.1 0.0.0.0 UG 202 0 0 eth0 |
...which is correct and without the extra default gateways. So, what do I need to do?
I notice there is version ~5.2.12-r1 which I could unmask and try?
Thanks UberLord.

Do you have both /etc/init.d/net.eth0 AND /etc/init.d/network running?

No, just /etc/init.d/net.eth0 (and /etc/init.d/net.lo) in the boot runlevel.

Well, I have removed net.eth0 from the boot runlevel and added network instead.
It has not made any difference to the multiple default gateways.
Here is the routing for my wireless connection:-
| Code: | thinkpad ~ # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0
0.0.0.0 192.168.0.1 0.0.0.0 UG 304 0 0 wlan0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
127.0.0.0 - 255.0.0.0 ! 0 - 0 -
192.168.0.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0 |
It all works, but can anyone explain why we have this now? Seriously, is there no-one?
