Ethernet Loopback plug - long term use

Posted on 2014-08-15

We sell a system that uses the MAC address of the PC's Ethernet port for licensing verification. If the port is not active the software will not run.

Several of our recent locations are setup with Wireless networking only which creates a problem.

I have tested with a Loopback plug in the Ethernet port and the system works as expected.

Are there any drawbacks to long term use of such a loopback plug?
Will this damage the port?

    Accepted Solution

    Using a loopback is fine.  I used to work at a company where we did something similar (for years) and have never had an issue with this.

    with more and more tablet-style devices, you may need to reconsider this strategy, as wired ports may cease to exist.
    an alternative would be Hard Drive serial numbers
    type VOL at a cmd prompt to get them.
