thanks for your reply. i use the kernel aodv implementation of the nist (means the following one). http://w3.antd.nist.gov/wctg/aodv_kernel/ When the aodv is running and i try to load the ip_queue module by modprobe ip_queue, it gives the message that device or resource is busy, insmod ip_queue failed. But when i stop the aodv and load the ip_queue module, it dont give any message. After that i give one rule to queue udp packet going through 6002 port (just for testing). When any packet go through this port, both the machine hangs. I dont know why this is happened. Do u know any alternative by which i can modify any ongoing or upcoming packets in adhoc network. mahbub --- Tobias DiPasquale <codeslinger@xxxxxxxxx> wrote: > On Wed, 26 Jan 2005 07:58:23 -0800 (PST), mohammad > Mahbubur rahman > <mahbub71@xxxxxxxxx> wrote: > > Hi, > > I am working on an Adhoc network running kernel > AODV > > version 2.1 (on Redhat linux kernel 2.4.20).
