Working GSM1800 config for latest OpenBSC

I have a ip.access nanoBTS (version 165AU9012)v(37) and have been using it with a very early version of OpenBSC (OpenBSC 0.01) and am now trying to upgrade to the latest version downloaded from GIT (OpenBSC version 0.9.0.565-993d). When I use the configuration that works on the old version, with this latest version, I get the following error: user@ubuntu:~/openbsc/src$ ./bsc_hack <0005> bsc_init.c:1024 WARNING: You are running an 'accept-all' network on a BTS that is not barred. This configuration is likely to interfere with production GSM networks and should only be used in a RF shielded environment such as a faraday cage! <0005> bsc_init.c:1024 WARNING: You are running an 'accept-all' network on a BTS that is not barred.
