[Freeipmi-users] ipmiping adversely affecting ipmitool

[Dick.Detweiler]

Hello all,

I am working on a multi-threaded app that searches a range of a IP addresses 
for IPMI devices and gathers info about any IPMI devices it finds.  A thread is 
spun for each IP address to be searched.  I am using ipmiping from the freeipmi 
suite to find them and ipmitool to get the info.  I have isolated an 
interesting problem.  If a thread for an IP address that will fail the ipmiping 
is included in the range, than other threads will from time to time fail 
getting information via ipmitool.  The symptom is that the ipmitool request 
will return an OK status but there will be no data returned.

You could test this by setting up an easy program that spins threads that 
perform ipmiping, then if 1.5 or 2.0 are returned, send an fru print command 
using ipmitool, then echo or save the output to a file.

I wonder if ipmiping is leaving the open-ipmi driver in a weird state so that 
when ipmitool runs its confused at times.

Any ideas what this might be?

Thanks,
