sorry for the constant revision (was: re: purple haze)

Last email for a while, i promise; i'm chainsmoking packets at this 
point.  but i found this-

---
2005-11-01 14:14:20 TCP tests completed normally
2005-11-01 14:14:20 Execution of 'fping -Ae' failed with error-code 99
2005-11-01 14:14:20 Sending results for service conn
---

Okay, it can't find fping.  But...
---
hobbit at randomaccess ~/server/bin $ more ../etc/hobbitserver.cfg |grep fping
# Make sure the path includes the directories where you have fping, mail 
and (optionally) ntpdate installed,
FPING="/usr/sbin/fping"                                 # Path and 
options for the 'fping' program.
hobbit at randomaccess ~/server/bin $ /usr/sbin/fping -Ae brassai
10.10.10.15 is alive (0.15 ms)
hobbit at randomaccess ~/server/bin $
---

So it should be finding fping just fine, and fping is working.
The path is in hobbitserver.cfg:
---
# Make sure the path includes the directories where you have fping, mail 
and (optionally) ntpdate installed,
# as well as the BBHOME/bin directory where all of the Hobbit programs 
reside.
PATH="/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/home/hobbit/server/bin"
...
# For bbtest-net
...
FPING="/usr/sbin/fping"                                                 
# Path and options for the 'fping' program.
---

and

[bbnet]
        ENVFILE /home/hobbit/server/etc/hobbitserver.cfg

------------

So, by all the above:  fping is functional, it is accessible by the 
'hobbit' user, it can reach the clients, it is in the PATH, it is 
defined in the ENVFILE bbnet is using.

So what's gone wrong??
