SSH, ping over IPv6 only, not IPv4

[gerry s]

Hello All,

I'm running "Linux beaglebone 3.8.13-bone80 #1 SMP Wed Jun 15 17:03:55 UTC 2016 armv7l GNU/Linux" on a Rev C BBB.

Yes, this is an old version, but have to remain on this due to the application, and have the latest eMMC(5.1) support(Thank you Robert!).

I had a query a while back about disabling wicd breaks networking here:https://groups.google.com/forum/#!searchin/beagleboard/wicd|sort:date/beagleboard/jxJzB6MlqeA/I3eHMpBnBAAJ

However, I found out that IPv6 works, so does beaglebone.local via putty or ping.

Now, I feel I may have broken some networking file when disabling wicd that caused this.

The following services are disabled:

   sudo update-rc.d apache2 disable
   sudo update-rc.d wicd disable
   sudo systemctl disable cloud9.service
   sudo update-rc.d saned disable
   sudo update-rc.d lightdm disable
   sudo systemctl stop graphical.target

   sudo update-rc.d  alsa-utils disable
   sudo systemctl disable  bonescript-autorun.service
   sudo update-rc.d  cpufrequtils  disable
   sudo update-rc.d  hdparm  disable
   sudo update-rc.d  loadcpufreq  disable
   sudo systemctl disable  wpa_supplicant.service
   sudo systemctl disable  bonescript.socket
   sudo systemctl disable cloud9.socket
   sudo systemctl disable graphical.target

 

This is my /etc/network/interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto eth0
#iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

# The secondary network interface
#auto eth1
#iface eth1 inet dhcp

# WiFi use: -> connmanctl

    netmask 255.255.255.252
    network 192.168.7.0
    gateway 192.168.7.1

ifconfig:

Does anyone have any suggestions to get IPv4 back.

Thank you,
