I just realized that using the 127 and 102 addresses don't work with the probe on the E310. It only works when I don't use the arg flag.

Nope, but it fails in a weird way. I disconnected the E320 to make sure this issue wasn't due to it, but it still acts the same. If I run: uhd_usrp_probe --args "addr=127.0.0.1" root@ettus-e3xx-sg3:~# uhd_usrp_probe --args "addr=127.0.0.1" [INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106400; UHD_3.11.0.1-0-unknown Error: i2c_zc_impl recv timeout Reading up on the USRP2, they specifically say that you need to be on different subnets if you are using more than on device. I wonder if this is the case here too? https://files.ettus.com/manual/page_usrp2.html#usrp2_network_multidev ________________________________ From: Nate Temple <nate.tem...@ettus.com> Sent: Friday, June 7, 2019 12:17 PM To: Jason Matusiak Cc: Marcus D Leech; Philip Balister; Ettus Mail List Subject: Re: [USRP-users] E320 hogging the network Hi Jason, On the E310, if you pass the device arg addr with 127.0.0.1 does it work as expected? uhd_usrp_probe --args "addr=127.0.0.1" Regards, Nate Temple On Fri, Jun 7, 2019 at 9:10 AM Jason Matusiak via USRP-users <usrp-users@lists.ettus.com<mailto:usrp-users@lists.ettus.com>> wrote: Darn, I was hoping that was it, but I don't think so. Here is the result from my E310: eth0 Link encap:Ethernet HWaddr 00:80:2F:25:44:46 and now the E320: sfp0 Link encap:Ethernet HWaddr 00:80:2F:24:C2:FB If I ping each device on my host, then run arp, I see this (the mac addresses match up correctly): Address HWtype HWaddress Flags Mask Iface 192.168.10.45 ether 00:80:2f:24:c2:fb C p4p1 192.168.10.95 ether 00:80:2f:25:44:46 C p4p1 I figured that that would be fine though because I have the same issue when I am running commands ON my E310. And if it was a routing issue, it would mean that both my machine and the E310 and the E320 were being screwed up. ________________________________ From: Marcus D Leech <patchvonbr...@gmail.com<mailto:patchvonbr...@gmail.com>> Sent: Friday, June 7, 2019 12:01 PM To: Jason Matusiak Cc: Philip Balister; Ettus Mail List Subject: Re: [USRP-users] E320 hogging the network Check the MAC addresses. I know that on some ARM platforms that has to be programmed in at boot and perhaps these system images have it set to the same value.

It is really weird that when I am on the E310, and set the ip-addr to himself, that he would even look off the device.... They both have hostnames and they are not similar to each other at all. ________________________________ From: Philip Balister <phi...@balister.org<mailto:phi...@balister.org>> Sent: Friday, June 7, 2019 11:10 AM To: Jason Matusiak; Ettus Mail List Subject: Re: [USRP-users] E320 hogging the network Check each ones ip address, likely by running ifconfig. In the back of my mind, I recall something like this in the E100 days. Do they have the same hostname?
