The ScopTEL PBX software has an unique problem when you are trying to set it up inside an OpenVZ Virtual Machine. If you install ScopTEL PBX and run the registration program it will fail. That’s because the registration process requires that it has access to the MAC address on eth0 in order to work. But there is a way around it. You can make the eth0 device appear within the VE as follows:
vzctl set $VEID --netif_add eth0 --save
This command build a line in your OpenVZ configuration file that looks like this:
Initially the values of eth0 (XX) match the Ethernet hardware card and the values of veth101.0 (YY) is random. The important point is that the XX values is the MAC number that ScopServ will see when you register your application.
You can check your virtual device from within the VE as follows:
ifconfig -a eth0 Link encap:Ethernet HWaddr FF:12:34:56:78:90 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
When you see the eth0 device in your Virtual Machine and are happy with the MAC number then you can go ahead and register your application and it will actually work.
