Hello,
I have tried to deploy 1040 sensors in a lab environment and the sensors are not registering with the Assurance server. I see a packet received on port 2000 of the server but the server isn't responding. The sensor shows "Not communicating with the receiver". I've tried restarting the services and rebooting the entire VM with the same results.
Below is the information displayed on the 1040 sensor when viewed from the web browser:

A tcpdump via root on the server shows the following incoming packet to the server but no response is sent:
18:31:02.349972 IP 10.1.24.105.1024 > LACPCA1.2000: S 39146440:39146440(0) win 5840 <mss 1460,sackOK,timestamp 2265 0,nop,wscale 0>
A "show ports" from the server shows tcp port 2000 opened by the QOVR process:
Process : CSCO.QOVR (23896)
tcp: :::5665, :::5666, :::5667, :::5668, :::5669, :::5670, :::5671, :::5672
, :::5673, :::5674, :::5675, :::5676, :::5677, :::5678, :::5679, :::5680, :::2000, :::5681, :::5682, :::5683, :::5684
udp: :::5666
I attempted to stop the process using the "pdterm QOVR" command and waited 5 minutes and then issued the "pdexec QOVR" command. I also tried "application stop cpcm" and then the "application start cpcm". I added a second 1040 sensor with the same results.
Thanks,
Pat Devaney
