N210 not accepting uhs commands, but I can ping it.

Hello,

Hope everyone is well.  I am having trouble communicating with my N210.  I hope some can offer some ideas.  Here are the details...

USRP: N210
OS: Ubuntu 23.04, Codename lunar
Computer: HP FireFly,
Connectivity:
      opt1:  Thunderbolt port + Sonnet Tech 10GSF
      opt2:  Thunderbolt port to RJ45

I can ping the unit.... However, when I try the uhd_usrp_probe and uhd_find_devices commands... I get the following — not very promising...

$ uhd_usrp_probe
[INFO] [UHD] linux; GNU C++ version 12.3.0; Boost_107400; UHD_4.6.0.HEAD-0-g50fa3baa
Error: LookupError: KeyError: No devices found for ----->
Empty Device Address

$ uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 12.3.0; Boost_107400; UHD_4.6.0.HEAD-0-g50fa3baa
No UHD Devices Found

Thank you in advance for your help

That's an unusual address for a "stock" N210.  Normally, they're at
192.168.10.2.  Do you have a dedicated connection to
  the USRP N210?

Also, the netmask on your machine would normally be 255.255.255.0

Hello Marcus,

I am going off of a sheet of paper that was laminated on the lid of the USRP. I am thinking someone must have changed the address and the net mask.  BTW I did try the out-the-box address and mask... (192.168.10.2 and 255.255.255.0) -- unfortunately it dd not help.  Also, full disclosure I am trying a MIMO set-up; however, at the moment I am just working with a single radio.  Is there a way of interrogating the radio... to confirm the address and mask?

Thanks again... for all your help.  I am looking forward to any additional suggestions.

Regards,
AJ

You can run Wireshark on the interface and listen to ARP responses. You can
also go to safe mode:
https://kb.ettus.com/N200/N210_Device_Recovery#Safe_Mode

Your ping might be pinging something else with the same address.
