Hi,

Sorry for the delay.

I guess these message are just warning on Python 2.

On Python 2, the "implicit relative import" is allowed, so interpreter try to 
find
modules from current path and will fail to find "os" module from "ryu.services
.protocols.bgp.bgpspeaker.application".
OTOH, on Python 3, the implicit relative import is NOT allowed, then no warnings
should be shown.

You can ignore these messages, but I will send a patch to suppress them.

Thanks,
Iwase

    Hi Pynbiang,

    Did you execute "sudo update-grub" command and then reboot?
    The outputs of "ip a" command shows IPv6 is NOT enabled...

    Thanks,

             Hi Pynbiang,

             Mininet does "disable IPv6" with some reason, I guess.
             But on my environment, I can run Mininet with IPv6 enabled.

             To revert "disable IPv6" settings;
             1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl 
-p" to take effect.
                ---
                 # Mininet: disable IPv6
                -net.ipv6.conf.all.disable_ipv6 = 1
                -net.ipv6.conf.default.disable_ipv6 = 1
                -net.ipv6.conf.lo.disable_ipv6 = 1
                +#net.ipv6.conf.all.disable_ipv6 = 1
                +#net.ipv6.conf.default.disable_ipv6 = 1
                +#net.ipv6.conf.lo.disable_ipv6 = 1
                ---
             2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in 
"/etc/default/grub"
                 and execute "sudo update-grub" command.
                ---
                -GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
                +GRUB_CMDLINE_LINUX_DEFAULT="text "
                ---
             3. Reboot.

             Then, confirm IPv6 addresses are assigned to interfaces on your 
machine.
             e.g.)
             $ ip a
             1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state 
UNKNOWN group default qlen 1
                  link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
                  inet 127.0.0.1/8 <http://127.0.0.1/8> <http://127.0.0.1/8> 
scope host lo

                     valid_lft forever preferred_lft forever
                  inet6 ::1/128 scope host
                     valid_lft forever preferred_lft forever

                 HI Fujimoto,

                 Yes, i guess you are right. i have the following lines of code 
in */etc/sysctl.conf*
                 /
                 /
                 /# Mininet: disable IPv6/

                 /net.ipv6.conf.lo.disable_ipv6 = 1/

                 And the following code in */etc/default/grub*
                 GRUB_DEFAULT=0
                 GRUB_HIDDEN_TIMEOUT=0

                 GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
                 GRUB_CMDLINE_LINUX=""

                 GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"

                 Is there anything wrong with my settings?.

                      It's just my guess, is IPv6 disabled on your machine?
                      Mininet does disable IPv6 automatically on its 
installation.

                      Could you confirm the IPv6 settings (e.g., 
"/etc/sysctl.conf" and
        "/etc/default/grub")
                      on your machine?
