[support] MN doesn't send Binding updates in foriegn network

[Ahmed Alaa]

Hello,
I'm Trying to run UMIP without IPsec testbed as a part of my graduation
project, i used the configuration steps in this link:
http://www.umip.org/docs/umip-mip6.html ,neglecting steps related to IPsec.

First i'll explain my testbed to make things clear: I have a laptop which
acts as a MN and a desktop computer on which i made the HA configuration,
this desktop has two ethernet cards the first one(eth1) is the Home network
interface and the second one(eth0) is the foriegn network interface.

I made an apache-server on the desktop and started sending a big size file
from the apache server to the MN via ethernet cable while the MN is still
in the home network
then i moved the MN to the foriegn network by unplugging the ethernet cable
from eth1 in the desktop then plugged it to eth0.By doing this the file
sending process stopped.

Using wireshark in monitoring the MN interface's and the two desktop
interfaces' (home and foriegn) traffic, i found that the MN doesn't send
the binding update message when moving to the foriegn network although it
sends router solicitation messages and acquires a new ip address (CoA) from
the same subnet of the foreign network.
I attached here:
1-UMIP log file.
2-MN & HA configurations.
3-Routing commands in file(/etc/network/interfaces) .
As they may help you detect what is our problem.

Regards,
Ahmed ALaa

What is your kernel ?
Did you follow the documentation there : http://www.umip.org/docs/umip-install.html#kernel

May you provide these wireshark captures ?

1-UMIP log file.
2-MN & HA configurations.
3-Routing commands in file(/etc/network/interfaces) .
As they may help you detect what is our problem.

---Routing commands in file(/etc/network/interfaces):.
#The loopback network interface
auto lo
iface lo inet loopback
#static routing
up ip -6 route add FEC0::1111/64 dev eth1
up ip -6 route add FEC0::2222/64 dev eth0
up ip -6 route add ::/0 via FEC0::2222:97A4:E2FF:FE1C:E2D1 dev eth0

First you shouldn't use FEC0::/64 (site-local) addresses which are deprecated.
The right way to do on a local network is to use ULAs: http://en.wikipedia.org/wiki/Unique_local_address

Then, what is FEC0::2222:97A4:E2FF:FE1C:E2D1 ? Is there a router in your architecture ? In this case, may you provide a figure of your architecture ?

?i changed the ip addresses into ULA and got the same result that MN
doesn't send BU when it reaches the foregin network despite acquiring CoA
,and in answer to your questions my kernel is 3.10.9 and yes i used that
link for kernel configuration and that IP (FEC0::2222:97A4:E2FF:FE1C:E2D1)
is the ip of the desktop interface that acts as the foreign network, i also
attached here a picture of my architecture.
i want to ask you whether my testbed architecture shown in the attached
picture is right or i should use two desktops each having two ethernet
cards one to be connected to other desktop and the other to act as home
network for the first desktop and foreign network for the second desktop ?
a also attached the MN wireshark capture, i hope this can clarify the case
and help you identify my problem.

Hello,
See below.
Best regards

Hello,
I'm Trying to run UMIP without IPsec testbed as a part of my graduation

http://www.umip.org/docs/umip-mip6.html ,neglecting steps related to
IPsec.

Post by Ahmed Alaa
First i'll explain my testbed to make things clear: I have a laptop

which acts as a MN and a desktop computer on which i made the HA
configuration, this desktop has two ethernet cards the first one(eth1) is
the Home network interface and the second one(eth0) is the foriegn network
interface.

Post by Ahmed Alaa
I made an apache-server on the desktop and started sending a big size

file from the apache server to the MN via ethernet cable while the MN is
still in the home network

Post by Ahmed Alaa
then i moved the MN to the foriegn network by unplugging the ethernet

cable from eth1 in the desktop then plugged it to eth0.By doing this the
file sending process stopped.

Post by Ahmed Alaa
Using wireshark in monitoring the MN interface's and the two desktop

interfaces' (home and foriegn) traffic, i found that the MN doesn't send
the binding update message when moving to the foriegn network although it
sends router solicitation messages and acquires a new ip address (CoA) from
the same subnet of the foreign network.
What is your kernel ?
http://www.umip.org/docs/umip-install.html#kernel
May you provide these wireshark captures ?

Post by Ahmed Alaa
1-UMIP log file.
2-MN & HA configurations.
3-Routing commands in file(/etc/network/interfaces) .
As they may help you detect what is our problem.
Regards,
Ahmed ALaa
---Routing commands in file(/etc/network/interfaces):.
#The loopback network interface
auto lo
iface lo inet loopback
#static routing
up ip -6 route add FEC0::1111/64 dev eth1
up ip -6 route add FEC0::2222/64 dev eth0
up ip -6 route add ::/0 via FEC0::2222:97A4:E2FF:FE1C:E2D1 dev eth0

First you shouldn't use FEC0::/64 (site-local) addresses which are
deprecated.
http://en.wikipedia.org/wiki/Unique_local_address
Then, what is FEC0::2222:97A4:E2FF:FE1C:E2D1 ? Is there a router in your
architecture ? In this case, may you provide a figure of your architecture ?

<testbed_architecture.jpg>
?i changed the ip addresses into ULA and got the same result that MN doesn't send BU when it reaches the foregin network despite acquiring CoA ,and in answer to your questions my kernel is 3.10.9 and yes i used that link for kernel configuration and that IP (FEC0::2222:97A4:E2FF:FE1C:E2D1) is the ip of the desktop interface that acts as the foreign network, i also attached here a picture of my architecture.
i want to ask you whether my testbed architecture shown in the attached picture is right or i should use two desktops each having two ethernet cards one to be connected to other desktop and the other to act as home network for the first desktop and foreign network for the second desktop ?
a also attached the MN wireshark capture, i hope this can clarify the case and help you identify my problem.

Do you have the corresponding MN logfile ? It is hard to investigate a problem with uncorrelated data.

Moreover, it would be nice to get the following information (when on the foreign network) :
ip -6 a
ip -6 r
ip -6 xfrm policy
ip -6 xfrm state
ip6tables -S

By the way, please check that no firewall or network manager is running.

Best regards
Emmanuel Thierry
