Run it using sudo ./OpenBTS Scott Sent from my BlackBerry 10 smartphone on the Verizon Wireless 4G LTE network. Original Message From: Lloyd C.

Subject: Re: [Openbts-discuss] Fw: Changing from multi band Frequency to 1900 Hi Ralph, I used devconfig GSM.Radio.Band to change my Range Devkit Freq to 1900. And now i am having big problem accessing my KIT with CLI. if i log int OpenBTS and CLI, if i try to use the basic commands it will return error, check below and help me with the solution. Or if i will need to build again. ubuntu@ubuntu:~$ sudo ifconfig eth0 192.168.0.99 netmask 255.255.252.0 ubuntu@ubuntu:~$ ssh openbts@192.168.0.22 openbts@192.168.0.22's password: Linux ubuntu 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:24:35 UTC 2011 i686 GNU/Linux Ubuntu 10.04.2 LTS Welcome to Ubuntu! * Documentation: https://help.ubuntu.com/ 158 packages can be updated. 123 updates are security updates.
