[Discuss-gnuradio] USRP N210 Network Issues
Hello list, Hopefully this is an appropriate place to ask this question: I'm trying to connect a host machine to a switch in which a USRP N210 is also connected. I have configured the host machine's IP to be static on the 192.168.10.0/24 subnet, and can successfully ping the N210 at 192.168.10.2. However, when I try to do a uhd_usrp_probe, the command simply returns the following: linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.004.002-152-gdb8f128e Error: Connection refused I have also tried to do uhd_usrp_probe --args=addr=192.168.10.2 in which case it returns the following: linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.004.002-152-gdb8f128e Error: LookupError: KeyError: No devices found for - Device Address: addr: 192.168.10.2 My first thought was that it is some kind of firewall issue, so I issued a sudo ufw disable, but the results didn't change (when trying to probe, it returns the above errors, I can still ping). According to http://files.ettus.com/uhd_docs/manual/html/usrp2.html#setup-networking, When the IP address is not specified, the device discovery broadcasts UDP packets from each ethernet interface. Which implies that broadcast UDP packets are not sent when an IP /is/ specified (which is what I did in my second attempt to probe the USRP), so I don't think it's a firewall issue. The switch is a Netgear GS608 which I don't think has broadcast storm control, anyway. Thanks for any help on the issue. -- Justyn ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

(Or are you using a switch because your host doesn't support 1GiGe?)

Re: [Discuss-gnuradio] USRP N210 Network Issues
I definitely should have mentioned that initially. Yes it works perfectly when directly connected. But I would like to configure the eth interface to have two addresses, because we're on a campus, one for network communications to the outside world, one for the USRP, and use a switch to bring it all together. Both the host and the switch support 1 GigE.
