Virgin Business Problems And Mac Address


PeterJames

Recommended Posts

Came in this morning to find the server had died, I have a backup at home but because the A27 is closed travelling to and from is a bit more than a ball ache, luckily my salesman was in Brighton so picks it up for me. Gets it to the office wires it all in and with the help of JW gets it up and running, it worked a dream everything saved from the night before nothing missing.

 

Then on to getting the internet working.

 

I'm with Virgin for business I have a Cisco modem plugged directly into the server and the SME server does the DHCP.  Anyway the modem will only talk to the mac address that it was set up with, apparently according to Virgin the only way to change this is to reset the modem and log in via their portal, the problem is they have switched the portal off as they are upgrading their systems.  If I was on their latest package this would not have been a problem. I have upgraded but they have told me 28 days until its done, I cant go 28 days with no emails.

 

So I take the old network adapter out of the old server and its PCI and all I have on the new server is PCI express. so I plug the PCI card in on a pc and hey presto I have internet. Great but I have 8 machines and two DVR's and a couple of intruder panels that need internet. I downloaded a program to make the pc a DHCP server but that didnt work.

 

I thought about buying a PCI to usb adapter but James says that would then use the USB MAC and not the Ethernet adapter MAC.

 

I have a mobile wifi modem but it has no Ethernet ports and only three of our machines have wifi the rest is all wired. Plus its a ball ache to keep swapping between networks to send receive emails

 

I am sure that there will be someone on here that will have the answer

Set your mobile up as a wifi hotspot as temp measure with a access point in bridge mode that does DCHP (edimax does), upgrade to a draytek router for next time USB dongle port on the front and use routers dchp.

Looked on line & then looked at my PC's

 

@ work I have a Lenovo desktop with a Realtek card at work (I assume on mother board) it lets me define the mac address

As petrolhead said, get a cable router and spoof the mac to the same as your nic

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

I can get sme to spoof a mac address via a script. Id rather not make it permanent and have a migrated way to restore after failure, ie not using the mac address.

But i can get you going monday but it will only work till rebooted.

If we can do that Tuesday that would be great I need to order a replacement server to so need a spec really

I have used macchanger before now.

This is a CLI utility which you can add the flag --mac= followed by device eth0

 

As James says this kind of thing will only work until a reboot.

You will need to add a script or change the configuration to keep it.

Not well up on CentOS but Debian would be in /etc/network

 

For issues like this, would it not be best to have the modem going via a router then to your server. Or do you have a reason for it being setup in this way?

Well I could have set up several ip's via a router but I never got round to it. I wanted the server to be the Firewall, not that it has prevented **** getting onto the engineers PC in the rest area.

Id need to setup danguardian for that which is what i use at work. But can block some usefull stuff too. I use whitelists for websites to allow downloads etc

I thought it would be something like that.

Yes you won't stop stuff like that with just a firewall.

 

I have always been happy with letting the router do all the firewall/management related tasks mentioned, I just keep it's FW upto date.

Allso use ufw on each machine too.

 

I have always found Clam a PITA, the last time I used it I remember it being very heavy on resources.

you should still get a wee router, something like a tplink 3420, then stick a dongle in the usb with a payg 3 simcard with £30 or so on it and set the router for 3g failover and spoof the mac on the wan port and you have yourself a nice bit of connection path redundancy, and you can change servers to your hearts delight and not have to worry about nics etc.
