Hello Mahmoud,
I had the same problem when I started using MIPL myself. The problem was not in the configuration of
MIPL, but in the network configuration of the machine where MIPL was run. I can reproduce the
behavior you've described by commenting the line with loopback (127.0.0.1) in "/etc/hosts" file, but
there may be some other reasons.
Good luck,
Michal

Hello all,
Brief description of my scenario
------------------------------------------
A)
- One PC with 3 interfaces (subnets) acting as a router
- One interface has HA and the MN initially connects to this interface
via WLAN
- Also has radvd that would advertize on WLAN interface and ethernet to
which the MN will eventually move
B)
- MN has 2 interfaces: WLAN and ethernet
- Initially connected to WLAN and then would "move" to ethernet by
disabling WLAN connection
C)
- I have a correspondent node PC but it does not have a MIP daemon
because i just want to test handover latency without route optimization.
Is that ok not to have the a MIP daemon on this PC?
What i did so far
---------------------
- Previously i had setup the IPv6 network and all nodes could ping one
another
- Have configured the MIP daemons on the corresponding PCs to be HA or
MN according to scenario
- Have also configured the radvd daemon
- I started all the daemons but i got errors for the HA and MN daemons
but the radvd was working well
Please see the files below and i would really appreciate if you can give
me some insights about what could be wrong and how to fix it.....
Thank you in advance

Note: Please note that i would not be needing route optimization so i
will disable it in my next try, is that ok or is there anything that
would be affected by this?
Please also note that am a newbie to linux so if there's some details to
stuff please mention them.....
I really would like to thank you all for your help and time....
Mahmoud
