Re: [Freeipmi-users] "Connection timed out" error

[Davidson Mike]

Al,

Unfortunately, setting the privilege level did not help.  I used the  
tcpdump utility along
with wireshark (formerly ethereal) to analyze the packet exchange  
between the linux
box running freeipmi and the target IPMI v2 compliant system.  It  
appears that the
'ipmi-sensors' command is attempting IPMI v1.5 session establishment  
which the HP
Proliant server (apparently) does not support.  So the packet  
exchange looks something like:

source                  protocol                packet description              
                        destination

impi-sensor command finally gives up and errors out with "connection  
timed out" error
I describe in my first email.

I can reproduce this exact behavior with ipmitool if I issue the  
sensor command using the
"lan" interface instead of the new "lanplus" interface option which  
supports IPMIv2/RMCP+
session establishment.

So my question is, does freeIPMI support IPMIv2 session  
establishment?  If not, is there
any plan to support it in the future?

Thanks,
Mike
