Altera OpenCL SDK License issue

Hi,

Yes, you still need a eth0 connection. I was able to add a tuntap interface named eth0. From what I understand everything sent to eth0 is simly sent to your regular connection. This is how to do it:

sudo ip tuntap add dev eth0 mode tap

Then you need to set the MAC address to the MAC address used by your license:

sudo ip link set dev eth0 address <your mac address>

For me the MAC for eth0 needs to be the same as for the enpX connection. I basically put this in a script to setup a tuntap interface with the right MAC address:

if 
then
    sudo ip tuntap add dev eth0 mode tap
    export link=$(find /sys/class/net -printf "%f\n" | grep enp)
    export mac=$(ip link show $link | awk '/ether/ {print$2}')
    sudo ip link set dev eth0 address $mac
fi

Then just check that eth0 shows up with the right MAC address:

ip link show

Hope that helps!
