Hi Marcus, Thank you for responding.
I can confirm that the USRP (192.168.30.2) and host (192.168.30.1) are working (streaming data), as I wanted to verify before trying the remote streaming. I have added the 192.168.30.30 as second interface on the host, and it is responding to pings. I do not have any firewall, they are all the same LAN / subnet. Based on the error “Requested remote UDP streaming, but transport adapter sfp1 does not support it!”, it doesn’t seem like the program is getting that far. I can also confirm that "sfp1” is the proper interface with the ipaddr 192.168.30.2. When monitoring the ethernet traffic, I never see a data packet with a source of 192.168.30.2 to a destination of 192.168.30.30. > > ``` > > Proto Recv-Q Send-Q Local Address Foreign Address State > > > > ``` > > > > ``` > > udp 0 0 127.0.0.53:53 0.0.0.0:* > > > > ``` > > > > ``` > > udp 0 0 0.0.0.0:111 0.0.0.0:* > > > > ``` > > > > ``` > > udp 0 0 0.0.0.0:631 0.0.0.0:* > > > > ``` > > > > ``` > > udp 0 0 0.0.0.0:5353 0.0.0.0:* > > > > ``` > > > > ``` > > udp 0 0 192.168.30.1:34602 192.168.30.2:49152 > > ESTABLISHED > > ``` > > > > ``` > > udp 0 0 0.0.0.0:50237 0.0.0.0:* > > > > ``` > > > > ``` > > udp 0 0 192.168.30.1:50938 192.168.30.2:49153 > > ESTABLISHED > > ``` I do not have an active listener on dest udp, but I also don’t see any traffic trying to set up a connection with 192.168.30.30.

Not sure if relevant, and I can’t find any information on what each of the address mean for USRP-2974, but the ip-addr0 and gateway are bogus values below. I do have streaming connection from host 192.168.30.1 to USRP 192.168.30.2, but still can’t get remote streaming to work. > ``` > | | gateway: 192.168.10.1 > > | | ip-addr0: 192.168.10.2 > > | | subnet0: 255.255.255.0 > > | | ip-addr1: 192.168.40.2 > > | | subnet1: 255.255.255.0 > > | | ip-addr2: 192.168.30.2 > > | | subnet2: 255.255.255.0 > > | | ip-addr3: 255.255.255.255 > > | | subnet3: 255.255.255.0 > > > ```
