SIOCADDRT: Network is unreachable (solved)

[complexity]

When I start net.eth0

root@gen3:/etc/init.d# ./net.eth0 start
* Starting eth0
* Bringing up eth0
* dhcp
* Running dhcpcd ...
Error, dhcpConfig: fopen /etc/resolv.conf: Permission denied [ ok ]
* eth0 received address 66.63.118.241/24
* Adding routes
* default gw 192.168.0.1 ...
SIOCADDRT: Network is unreachable

I gave the resolv.conf no permission so that it wouldn't be written over when the computer started for a quick fix.

But anyway I can ping use this computer fine, but anyone else connected to the network has no luck.

You've got an IP address, but the default gateway is on an entirely different subnet and the machine has no route to it.

Strange I forgot to mention that this just started happening today. For no apparent reason. So what should I look at to fix it.

[magic919]

Have a look at /etc/conf.d/net, perhaps? It can be completely empty for your set-up, even if that's not the perfect way.

2 Lines

config_eth0=( "192.168.0.1 netmask 255.255.255.0" )
routes_eth0=( "default gw 192.168.0.1" )

pleace set something diferent from 192.168.0.1 because thisis your gateway adress and try restarting netowrking through init.d

Code: Select all

root@gen3:/etc/init.d# ./net.eth0 start
 * Starting eth0
 *   Bringing up eth0
 *     dhcp
 *       Running dhcpcd ...
Error, dhcpConfig: fopen /etc/resolv.conf: Permission denied              [ ok ]
 *       eth0 received address 66.63.118.241/24
 *   Adding routes
 *     default gw 192.168.0.1 ...
SIOCADDRT: Network is unreachable

Where is it getting that default gateway from? That is an invalid gateway for a network with a host 66.63.118.241/24.

What problem were you trying to fix?

But anyway I can ping use this computer fine, but anyone else connected to the network has no luck.

Are you pinging by hostname or IP?

forgot to add that pleace try to look in /etc/conf.d/net.example for configuration you need, this is well documented file. pleace read.

Well...

Before

config_eth0=( "192.168.0.1 netmask 255.255.255.0" )
routes_eth0=( "default gw 192.168.0.1" )


After

config_eth0=( "192.168.0.1 netmask 255.255.255.0" )
routes_eth0=( "default gw 127.0.0.1" )


I changed them lines to that. And now it all works.

Thanks for all the help, really appreciate it.

Duh problem and solution - give root write access to resolv.conf as dhcpcd NEEDS it overwrite it unless given the -R option.
