Dell Poweredge 850 connection issue

Hi guys,

I had a rack server kindly donated by a freind who had to move his data center recently. Im currently trrying to set it up on a virgin super hub.

The rack server has both up and down network port we have both ports direct in to the hub and both set on the same internal ip manually.

one port network1 one prt network 2 in ubuntu.

In the HUB I have forwarded port 80 to this internal IP so that it can be used as a web server.
Both webmin and apache have been installed along with mysql and PHP 5.

Any ideas guys.

erm … none whatsoever as you haven’t said what the issue is ?

Is it even possible to assign the same IP to both network cards without creating a conflict ?

What does:



and what hapepns if you try to ping ?

ok issue is trying to connect to server externally to port 80 web server.

Its one network card with two ports.

I believe there are a few services on Virgin’s end that run on port 80, so that may conflict with they’re services.

Also, IIRC Virgin aren’t the nicest of chaps when it comes to running your own web server off of their “average joe” packages. Instead they look at someone who runs their own web server as a “business package consumer”, so you may receive a letter from them.

Just speaking from experience btw. I had Virgin some 10/11 months ago.

Also, if I were you, I wouldn’t use the Superhub for anything else than connecting you to the net. Ideally you’ll want to run your own router from the superhub in the so called “Modem mode”, that way you don’t get any of the failures that the superhub tends to be super at.

P.S. Want another Superhub? I’ve got 2? XD

ITs on a 120 meg down and 12 meg up.
I have a spare router that could be used if we need to set it for modem only on the super hub also.

Like I say, you’ll be far better off running your own router with the Superhub in modem mode. It should be far easier to configure that way. Just be sure your own router can handle the 120MB speed.

but you can access it on the LAN ? … what I’m trying to find out is, is this an issue with port forwarding in the superhub ONLY

I’d still like to know what

and if you can ping the server from the LAN

I’m going to assume the NIC just has 4 (or 2) active wires per port … but I’d assume the superhub isn’t smart enough to differentiate uplink/downlink … so is getting confused as to which port to send the data to.

I’d expect you’d need to do some routing in the router … but don’t know the superhub interface at all, and if it’s capable of that

it may be easier just to get a “normal” NIC … or as BkS suggests, find a router that does allow you to mess with the routing table and use the superhub as just a modem

Does the superhub firewall allow you to set rules by port ? rather than just IP ?

IP or Port, or Both IIRC.

Sorry, I meant the ethernet port … not port as in TCP or UDP port

Ah. I think it can, although I can’t remember of the top of my head. I’d have to fire up one of my own Superhubs tbh.

port triggering is available on the superhub ive also got the hub set for external admin access.

here is the output from ifconfig

Slowly getting a handle on this dual port network thingy … maybe :slight_smile:

Have you seen this:

Looking at it now.

As you’ll probably see, you can pretty much ignore everything I’ve said up to this point :slight_smile:

Did the server come preinstalled and set up … or have you just bunged Ubuntu on it ?

Is the bonding module loaded ?

lsmod | grep bonding

I installed fresh copy of ubuntu on after installing new hard drives.

I havent installed the bonding module but I maybe able to locate it via APT i guess.

I see that ifenslave-2.6 is available via apt.

The bonding module should already be present (but not loaded)… you just need to modprobe it to load it … but you need to use the correct parameters.

You can check it’s present with:

modinfo bonding


lsmod | grep bonding

will tell you if it’s loaded

Maybe you could Google “bonding two ethernet adapters in Ubuntu” or similar … and see what springs up ?

You might also add “networkmanager” to the search if you’re using the desktop version

And please let me know how you get on … as this has peaked my interest … may even try bunging a second NIC in myself :slight_smile:

Apologies for the late reply been massivley busy since i psoted up here last.

Seems that it was not two seperate ports with one for upload and one for downlaod but instead it was two seperate network cards.

It wouldnt allow for bonding, going to try disabling one of the cards and working with it that way for now il update this once i have further info.

Cheers for the support guys.
