Hi,
I am working on an Adhoc network running kernel AODV
version 2.1 (on Redhat linux kernel 2.4.20). The AODV
is running fine. Now I am trying to queue some packets
onto the user space for modification using libipq
library. But incase of running the libipq example
program, i have to load the ip_queue module by
modprobe ip_queue first. When i load this module and
running the example program, the machines are hanged.
Can anyone please tell me why??

Can anyone pls suggest me how i can get some packets
onto the user space for modification incase of ad hoc
network???

Mahbub

AFAIK, the current Linux implementation of AODV uses ip_queue.
Therefore, due to the limitations of ip_queue, you can't then use
anything else that would use ip_queue while you're running that. Where
did you get your implementation? Is it this one:

http://user.it.uu.se/~henrikl/aodv/

or this one?:

http://w3.antd.nist.gov/wctg/aodv_kernel/

If its the latter, disregard all of the above.

Re: Kernel AODV and libipq library

[mohammad Mahbubur rahman]

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.
