Hello :
It does sound strange,but is what I am experiencing. When I run the two
scripts namely tbf.init and tbf.down, following is the result of the
iterations..
-----------8<-------------8<----------------8<-----------
[root@bark@ece tc]# ./tbf.down
[root@bark@ece tc]# ./tbf.init
[root@bark@ece tc]# ./tbf.down
[root@bark@ece tc]# ./tbf.init
[root@bark@ece tc]# ./tbf.down
[root@bark@ece tc]# ./tbf.init

Hope this helps in shedding more light on the problem. Thank you once
again for your timely assistance.
