Re: [Discuss-gnuradio] USRP_N200 unable to connect via vmplayer

[Ankan Roybardhan]

1. I tried using vm bridged connection over NAT.. i assigned 192.168.10.1 and subnet 255.255.255.0 in the ubuntu network setting running on vmplayer.. I am pretty much sure about the other USRP IP since.. i used some other machine to do uhd_find_devices .. so check for their IPs..

2. My ethernet port is working fine on windows.. I though did not check it on my vm.. bt hopefully it is working since it is recognizing the LAN..

3. The sw is perfectly fine tested OK.

4. I changed it from dhcp to manual ipv4 settings as 1. the problem persists.. the device is on 192.168.10.3.. 

i did uhd_usrp_probe with --args=<ip of the usrp>... it says the same. could not find devices.. 

I feel there is a big issue with the vmplayer network settings with uhd...

Hi,

    Check if your usrp is surely on 192.168.10.3. Run uhd_usrp_probe and check if it is giving any output. Do you have gigabit ethernet card on your laptop. If not, you will have to use a switch in between and some times switch might be an issue. 

one more thing, are you connected on static ip? If you are on dhcp, change it to static ip and see.

You're sure its not at the default address 192.168.10.2?

Don't know if you have the same problem but I use a USB to GigE adapter from vmware player and I found that it ONLY works if I boot the VM with the interface that is connected to the USRP as the only active network connection. I can enable the network interface to the host OS after I boot and it still works but for some reason if the VMnetX interfaces are active at boot it messes up the ability to find the USRP.
