netmask doen't mach route address

explorer · 2011-06-15 17:23:31

Now I can not result full answers of system, the computer is on work.

I use this image - archlinux-2010.05-core-x86_64.iso

First, edit /etc/rc.conf
lo="lo 127.0.0.1"
eth0="eth0 192.168.10.79 netmask 255.255.0.0 broadcast 192.168.0.255"
INTERFACES(lo eth0)
ROUTES(gateway)
DAEMONS(syslog-ng network netfs crond)

Second, edit /etc/resolv.conf
nameserver 192.168.0.1

Then system reboot, but a network doesn't work. Ping doesn't answer.

When I add a route through the terminal from root
# route add -net 192.168.10.79 netmask 255.255.0.0 gw 192.168.0.1

gives out the following error
netmask doen't mach route address

In Ubuntu works without problems.

Prompt how to solve a problem?

Can you try using -host instead of -net?

From the route man page:
-net the target is a network.
-host the target is a host.

Didn't check, tomorrow I will check up and I will write result.

That is an invalid configuration. Either remove the broadcast part and let ifconfig calculate it for you, or enter the correct value for your netmask (192.168.255.255)

I check up both councils, but the network doesn't work.

Have you been through this wiki article?

explorer · 2011-06-16 10:46:18

I check settings again and has read article, but the Internet doesn't work.

explorer · 2011-06-16 11:30:21

Essence of a problem that my address in one subnet 192.168.10.x, and the gateway in other subnet 192.168.0.x In Ubuntu has solved this problem - enter mask 255.255.0.0 Arch Linux doesn't want to add these parameters in the routing table.

Weight of all has tried, but doesn't want to work.

They are not different subnets if you are using netmask 255.255.0.0

explorer · 2011-06-17 11:31:41

Options has left, as in the first message but no result.

If they not different why Ubuntu all works, and in Arch doesn't work?

ip a sh

Obviously they're not the same. I don't use Ubuntu so I don't know what it's done for you.

xangelux · 2011-06-18 05:21:32

First of all, explain what are you trying to do, 192.x.x.x is a private set of ip's, so it is not a usable public ip address. Second, de broadcast is allways the last ip of the set, so in your case, broadcast shold be 192.168.255.255. I've worked with Ubuntu and mainly it does things rather automatic if you set something wrong Ubuntu changes it to a default, this might be the case (I'm not sure of that)

Another thing is, 192.x.x.x is a C class ip address, maybe your configuration is set to use Subnetting instead of VLSM, subnetting doesn't support netmask other than the class subnet mask (in this case should be 255.255.255.0) I don't know for shure why does your system is do that.

Install 'iproute2' package and try again

EDIT: This is indicates that you haven't UPDATED your system since you installed it since 'iproute2' is now a dependency of initscripts so it should be installed on ALL systems. It it pointless anyone trying to help you with an outdated system. Update first: https://wiki.archlinux.org/index.php/Beginners'_Guide#Update_the_System

fukawi2 How I can update system if the network doesn't work?

How to manual install iproute2 from the terminal?

fukawi2 · 2011-06-20 11:32:58

Download the 'iproute2' package manually and install it using pacman -U

explorer · 2011-06-22 11:28:39

In Arch Linux has own format of packages - *.pkg.tar.xz

That's weird... You shouldn't have the address in there twice; there should only be the primary address (the one with /16). Also, your ether address shouldn't be xx:xx:xx:xx:xx:xx but I'll assume you've censored that for some reason.
Can you post your rc.conf file?

# ip r sh
192.168.0.0/16 dev eth0 proto kernel scope link src 192.168.10.79
default via 192.168.0.1 dev eth0

This appears valid. Are you able to `ping 192.168.0.1`?

Your 'broadcast' is still invalid in your rc.conf. Remove the broadcast part completely so it's just this:

eth0="eth0 192.168.10.79 netmask 255.255.0.0"
