Hello Aniruddha,
I don't know about NSIS, but i had an error that might be similar. I
was building a simple routing agent that at some point modified the IP
header of the packet by changing the IP-destination-addr with the
IP_BROADCAST address. And I forgot to restore the original IP header before
handing the packet to the port classifier , so I got the following error:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o30: no target for slot 0
_o30 type: Classifier/Port
content dump:
classifier _o30
0 offset
0 shift
2147483647 mask
1 slots
slot 255: _o17 (Agent/AllBroadcast)
AllBroadcast is the name of my agent.
So all i can say about your case is that somewhere a Classifier/Hash/Dest
(node's address classifier?) is being used and it is passed a packet that it
doesn't know how to classify !
Sorry I couldn't be of more help.
Good luck.
