Issue already solved, but the removal of check_link doesn't affect it.

1. What do the following commands say:
 ifup --version
 ifup --verbose eth0
2. What are the contents of:
 /etc/network/interfaces
   (if it exists - I use Debian Lenny and I am not familiar

If you remove the check link parts, do you keep seeing the issue? Would also
be nice to try with a different NIC type (e1000 or virtio)

Re: weird network issue

Damn, How did I miss that?

it appeared that VMWare's network template script sucks, it did put some
numbers in the route-eth0 file. I emptied the file and now it works :)

Thanks a lot :)

RE: weird network issue

[Baruch Shpirer]

 

You sure you don’t have some static routing cmds some where?

Changed subnets and forgot to remove them completely?

 

Red Hat/Fedora: inside /etc/sysconfig/network-scripts/route-eth0 file

Debian Linux:  inside /etc/network/interface file

 

Using ip forwarding?

Subject: weird network issue

 

Hi,

 

I'm getting some really weird error, even though the network on the machine 
works well.

When I'm doing: "service network restart" or "ifup eth0", I'm getting a 
message: RTNETLINK answers: Network is unreachable.

 

It is reachable. route's output is perfectly ok, the machine can access the net 
and I can access it from outside. DNS works, ping works etc..

 

Looking at /var/log/messages, all I see is:

 

Feb 14 13:23:00 testing23 kernel: eth0: intr type 2, mode 0, 1 vectors allocated

Feb 14 13:23:00 testing23  kernel: eth0: NIC Link is Up 1 Mbps

 

Here is my ifcfg-eth0 (it's a virtual machine, so the check_link stuff is what 
vmware added)

 

DEVICE=eth0

ONBOOT=yes

USERCTL=no

BOOTPROTO=none

NETMASK=255.255.255.224

IPADDR=82.XXX.XXX.203

PEERDNS=no

 

check_link_down() {

return 1;

}

HWADDR=00:50:56:a3:00:18

GATEWAY=82.XXX.XXX.193

TYPE=Ethernet

 

Any suggestions?

 

Thanks,

Hetz

Re: weird network issue

[Omer Zak]

Hello Hetz,
1. Does the virtual machine have additional network cards (eth1, eth2,
etc.)?  If yes, you may be accessing the network via those cards rather
than via eth0. (Statement about proper routing withstanding.)
2. Which Linux distribution is running in the virtual machine?

Google search (rtnetlink answers network is unreachable) yielded the
following possibilities:
- Misconfigured IP address in firewall script.
- Network card does not exist (as far as the virtual machine is
concerned).
- Misconfigured network card.

Two of the URLs I got from the above Google search:
http://www.linuxquestions.org/questions/linux-networking-3/server-ifup-rtnetlink-answers-network-is-unreachable-problem-340915/

Any if-pre-up rule?

It is reachable. route's output is perfectly ok, the machine can 
access the net and I can access it from outside. DNS works, ping works 
etc..


Looking at /var/log/messages, all I see is:

Feb 14 13:23:00 testing23 kernel: eth0: intr type 2, mode 0, 1 vectors 
allocated

Feb 14 13:23:00 testing23  kernel: eth0: NIC Link is Up 1 Mbps

Here is my ifcfg-eth0 (it's a virtual machine, so the check_link stuff 
is what vmware added)


DEVICE=eth0
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
NETMASK=255.255.255.224
IPADDR=82.XXX.XXX.203
PEERDNS=no

check_link_down() {
return 1;
}
HWADDR=00:50:56:a3:00:18
GATEWAY=82.XXX.XXX.193
TYPE=Ethernet

Any suggestions?

Thanks,

google seems to find quite a lot of hits for the error, most of them sum up
to "misconfigured ETH"

weird network issue

[Hetz Ben Hamo]

Hi,

I'm getting some really weird error, even though the network on the machine
works well.
When I'm doing: "service network restart" or "ifup eth0", I'm getting a
message: RTNETLINK answers: Network is unreachable.

It is reachable. route's output is perfectly ok, the machine can access the
net and I can access it from outside. DNS works, ping works etc..

Looking at /var/log/messages, all I see is:

Feb 14 13:23:00 testing23 kernel: eth0: intr type 2, mode 0, 1 vectors
allocated
Feb 14 13:23:00 testing23  kernel: eth0: NIC Link is Up 1 Mbps

Here is my ifcfg-eth0 (it's a virtual machine, so the check_link stuff is
what vmware added)

DEVICE=eth0
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
NETMASK=255.255.255.224
IPADDR=82.XXX.XXX.203
PEERDNS=no

check_link_down() {
return 1;
}
HWADDR=00:50:56:a3:00:18
GATEWAY=82.XXX.XXX.193
TYPE=Ethernet

Any suggestions?
