Hi Rob, Good catch! When I go to the Network Settings under IPv4, I have it set to manual with the static IP 192.168.10.2 and the netmask to 255.255.255.0, but the ifconfig shows that the netmask is still 0.0.0.0. I set it to 255.255.255.0 with a sudo ifconfig command, and after a restart I can now run uhd_usrp_probe! I still get some warnings that I might have to take a closer look at, but this is at least a step past the logjam, thank you!

Why is this 0.0.0.0 instead of 255.255.255.0?

Based on what I'm seeing, I believe it has something to do with my PCs network settings because I can communicate with one port at a time without any problems. My current setup is a PC with one Ethernet connection on the motherboard and a separate WiFi PCIe card. I connected the E320's RJ45 port to my WiFi router and the Ethernet connection is connected to the RJ45-to-SFP adapter on the E320's SFP+ port. I am able to ssh into the E320 and run the example programs on there, but when I try to run uhd_find_devices or uhd_usrp_probe on my PC, there are issues. I am running UHD 3.15 on both my PC and the E320.
