Immediately above "Traceback (most recent call last):" in the command window is there any error?
The most common I get are: t...@tim-laptop:~$ usrp2_fft.py *eth0: SIOCGIFINDEX: No such device* or t...@tim-laptop:~$ usrp2_fft.py -e eth1 *socket(PF_PACKET, SOCK_RAW, htons(0xBEEF)): Operation not permitted eth1: socket: No such file or directory* ---- In the former case for some reason my ubuntu install randomly changed eth0 to eth1 , run ifconfig and try: usrp2_fft.py -e ethX where X is the number listed in `ifconfig | grep eth` If you get the second error for some reason usrp2_socket_opener has lost permissions (or you've been running as root when it worked in the past) sudo chmod +s /usr/bin/usrp2_socket_opener Should fix this problem. Last idea is if you've tried the VRT firmware/gnuradio code on the other PC -- the control packets have changed in this release so wont work with stock git/packaged gnuradio versions.
