Issues Updating IP Settings using the exacqVision Client

In various versions of exacqVision, version 8.8 and earlier, we have seen issues updating the IP settings on Linux servers using the exacqVision client. If you run into this issue, you can confirm the settings applied or change the settings using the method below. The exacqVision Client reads from the Interfaces file so if this file is correct, then you IP settings are correct on the system.

<br>

  1. Open Terminal.
  2. Type sudo nano /etc/network/interfaces.
  3. Either confirm your network settings have been applied or change to the settings desired.
  4. Restart network interface using sudo ifdown ethx and then sudo ifup ethx (x being eth0 in this case).
