Problem with Interface

Azurel

Azurel

Silver Pleskian
Hi,

I have installed MRTG and my traffic statistic für incoming traffic looks wrong.

In Plesk -> Server -> IP Addresses it says (for ipv4 and ipv6) as Interface "eth0".

MRTG says: "WARNING: Could not match host:'public@localhost' ref:'Name' key:'eth0'"
its only work with eth2

System says:
# netstat -i
Kernel Interface table
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth2 1500 0 2456830626 0 0 0 1892261100 0 0 0 BMRU
lo 16436 0 2109238015 0 0 0 2109238015 0 0 0 LRU
Click to expand...


What is "eth0" in Plesk? Why my incoming traffic is wrong? I use this cfg for MRTG

Target[traffic]: #eth2:public@localhost
SetEnv[traffic]: MRTG_INT_IP="XX.XX.XX.XX" MRTG_INT_DESCR="eth2"
MaxBytes[traffic]: 125000000
Title[traffic]: Traffic Analysis
PageTop[traffic]: <h1>Traffic Analysis</h1>
<div id="sysdetails">

<td>eth2</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
</table>
</div>
Options[traffic]: growright,noinfo

Can anybody help me here?

My incoming traffic is like a line (very small differences).
My outgoing traffic has nice waves like connection stats.
 
Hello,

You can check your all interface card through "ifconfig" command on your server through SSH
 
Azurel,

it seems, that your network cards are wrong configurated.
What do you get, if you click on "reread IP data"?

Kind regards
Henning
 
Hi Azurel,

It could be based on the installation-package of HostEurope. You can have a look at:
/etc/sysconfig/network-scripts/

Are there any scripts containing eth0?
What is inside of the folder?

You could rename the interface, but that's not the perfect way ...

Kind regards
Henning
 
I get this mail now for first time:

The Web Proxy Server (Nginx) service on host rsXXXXX.rs.hosteurope.de is down.
The problem was discovered on Nov 26, 2013 01:29 AM.
Click to expand...

But in shell
# service nginx status
nginx (pid 876) is running...
Click to expand...

Now I get email with
The Web Proxy Server (Nginx) service on host rsXXXXX.rs.hosteurope.de has been started on Nov 26, 2013 01:34 AM.
Click to expand...

Is this a problem with the new setting "eth2"?

Could you please provide the ifcfg-eth0? It looks very curious.

The mail you've got could be normal. The nginx server could have been restarted due configuration changes i.e.!
So don't worry. Our servers are being backed up at 4 am (GMT+1) and we have set, that the websites aren't allowed to be reachable so we do get at this time the same mails (as information).

Kind regards
Henning

FYI: I've doublechecked the default configuration from hosteurope on a customers site and I can confirm, that the standard installation normally uses eth0.
 
For security reason I have masked some numbers. Thanks for your help. ;)

Hi Azurel,

is the IP address of all three eth[0-2] the same? because of the same Gateway.
Can you fire up the eth0? The command should be "ifconfig eth0 up".

Do you get any message or error?

Kind regards
Henning
 
Hi Azurel,

is it a real server or an VM?

Further more, please post the following file:

/etc/udev/rules.d/70-persistent-net.rules

Kind regards

Hi Azurel,

in this file, you could swap eth0 and eth2 to get it back working.
You should open a support ticket at Hosteurope as it looks like a hardware change.

But if you change the name and when you do a reboot, all interface names should be correct again, so all your software should work.
Please note, that you should "reread IP" again ;-)

Now /etc/udev/rules.d/70-persistent-net.rules have only one rule for "eth0".

/etc/sysconfig/network-scripts/ looks now:

With click on "Reread IP" (plesk panel) its now "eth0".
 
Here my start question again, because changes in interface nothing change with my problem.

Here a picture of traffic statistics:

Why I have constant 300kb incoming traffic? Thats was since beginning of new server and ~0 incoming connections.

Can anybody help me here?
