Hotspot snmp problem

Hi again,

I have been doing reading on the Simultaneous-use with the radutmp module 
and sql.  I was hoping someone could help clarify some confusion I 
have.  Using the Sql notes I inserted the Simultaneous attribute to the 
radgroupcheck table, although I did change the dialup attribute to dynamic 
as that is the group my login belongs to.  Using the sql.conf I uncommented 
the simul_count_query (simul_verify_query was already uncommented).

I still see no output in the radutmp file, even though during loading it says,
Module: Loaded radutmp
  radutmp: filename = "/usr/local/var/log/radius/radutmp"
  radutmp: username = "%{User-Name}"
  radutmp: case_sensitive = yes
  radutmp: check_with_nas = no
  radutmp: perm = 384
  radutmp: callerid = yes
Module: Instantiated radutmp (radutmp)

radacct has lots of details,

When I have an account start time and end time in the radacct, does that 
not mean simul checking should be working?
Sorry for my lack of understanding on this process, I have read lots of 
docs, I think it's just going to take me a little longer to get it.  :)

Thank you again for all your help,
