Re: [Discuss-gnuradio] Remote Access to USRP testbed with GNU Radio
I believe people are answering the question but are slightly off target. Create a group on your Linux distribution call USRP, make sure those users you want control the USRP as users (AND NOT ROOT) are in this group. The go read the gnuradio wiki about the other changes granting device permissions etc. This is how remote users gain control of the USRP locally without sudo as well as over SSH whether the machine is accessible over a LAN only or the full internet.

I want to add that as a possible feature--perhaps prompt for the userids you wish to be added or something.

Re: [Discuss-gnuradio] Remote Access to USRP testbed with GNU Radio
Thanks a lot for all the replys! Sorry that I forgot to mention I am using USRP2. I think the link is for USRP which create a usrp group for non root control.
