| Remember that you in fact are not required to "Login" to the USRP at all, it isn't an interactive device, more like a peripheral device to a host computer. Thus your remote access limitation is purely dependent on the remote host you utilize to run GNURadio to interface to the USRP. The main issue you are like to run into is using update intensive GRC graphical tools such as FFT via X or VNC which can be very problematic over WANs. In terms of the USRP itself, if the location is truly remote with no local support then it would be wise to utilize A USRP other than the USRP2 since this model requires the SDCard to be physically replaced to upgrade firmware+FPGA. It would also be wise to have a remote accessible PDU so you can power cycle the USRP if necessary.
I've built austere "lights out" remote satellite ground stations that use USRP's with great success.

Although I was not the one who set it up, as far as I know, nothing additional had to be done to enable this. I simply logged in as the user account under which GNU Radio had been installed. The machine was running Ubuntu, in case it matters.

Hi, all
We are interesting to build up a USRP testbed which allowed the guest remote access to do some experiments.
I have seen someone's youtube video that they control the USRPs to transmit different signals through SSH access.
But I want to double check if it allowed guest control of USRP devices ?
Are there any other settings I need to take care of, in order to implement this?
Thanks a lot for any suggestions!
