Hi im doing this article.

https://bastienbaranoff.wordpress.com/2018/08/10/gsm-base-station-with-two-osmocom-bb-compatible-phones-on-kali-rolling/

But this error comes at shell #4

root@kali:~# osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -m -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM
There is no such command.
Error occurred during reading the below line:
 timer t3103 0

<0005> bsc_init.c:551 Failed to parse the config file: '/root/.osmocom/open-bsc.cfg'
Reading config failed. Exiting.

What should i fix it ?
