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.
