Hi Daniel,
Hi,
We are currently using HIPL with version 1.0.6-6. That is to say the one
from the repository.
We are testing mobility and multihoming performance of HIP.
We have a multihomed peer with three interfaces, and we would like this
peer to set a HIP connection with those three different IP addresses. In
the hipd_conf file, we set the options to locator on and shotgun off. We
expected to see some UPDATE message with LOCATOR payloads inside but
could not catch any with wireshark version 1.3.3. We took the one from
the INFRAHIP website.
"hipconf locator on" is not currently not supported. I recommend turning
this off as it is in the default configuration.
When we added one new interface, no UPDATE message was sent, and when
the active interface is removed, we have no handover.
Strange, there should be a handover after the active interface is
removed. Please try without locator support.
It seems that we have not activated the UPDATE message. I remember that
in previous version of HIPL there were in the hipd_conf file the options
handover soft | hard. Those options are still documented in the hipconf
command line, but does not work anymore. Do you know how can we activate
handover mechanisms with the current HIPL?
The hard and soft options are not functional at the moment.
We also tried to set the shotgun option on. We expected that when
initiating the connection with the three interfaces we would have three
HIP BEX. We see three I1, R1, and I2 messages but only one R2. However
even on the channel where the BEX has been completed, our ftp does not
send data. Do you know if this option can work with a regular FTP
client server?
Maybe that could help, we can see TCP_SYN, but no TCP_ACK from the
server, and the server has been started. So it seems the messages does
not reach the TCP layer.
Shotgun sends the I1 message using all possible combinations. It does
not trigger multiple base exchanges.
The reason why shotgun is disabled at the moment is that it does not
work with mobility yet.
One last question is do you know if that 's possible to modify the
puzzle difficulty from the hipconf file?
/etc/hip/hipd_config:
set puzzle all <new_value>
