My main computer is running Ubuntu 18.04, I just bought my BBG for about 1 week.

More information about my BBG :

 root@beaglebone:~# uname -a
Linux beaglebone 3.8.13-bone71.1 #162 SMP Fri Oct 16 07:27:34 CST 2015 armv7l GNU/Linux

It worked well until yesterday, I don't know why I cannot access to 192.168.7.2 When I try to access, it just displays «This site is inaccessible, 192.168.7.2 does not allow connection ». When I run ifconfig, I can see:

In addition, I could not access 192.168.7.2:3000 which is cloud9 IDE, but when I try to find his folder, I see:

    From where do you try to access 192.168.7.2? – Hauke Laging May 25 '18 at 17:56
  • Thank you for your reply @HaukeLaging. From Chromium and Firefox I try to access 192.168.7.2 – CodeLover May 25 '18 at 21:02
  • What is the result of command: netstat -an|grep 3000? Do you have this software run? – Romeo Ninov May 26 '18 at 5:53
  • @RomeoNinov this command does display anything : debian@beaglebone:~$ netstat -an|grep 3000 debian@beaglebone:~$ – CodeLover May 26 '18 at 12:20

    @IchrakMansour, this mean you have nothing to listen on this port. So start the software – Romeo Ninov May 26 '18 at 12:35
