[rhn-users] how to disable kernel from processing incoming andoutgoing packets??

[Philip Lefort]

Hi,
 
How about turning of IP forwarding? ck out /etc/sysctl.conf.  There's an option to turn off IP forwarding.  (It's right after the comments).  You might want to run "service network restart" for good measure.
 
I hope this fixes your problem.

Hi,

 

Thank you for prompt reply.

After deleting the current profile.

I started the process again

l         From the command line I typed rhn_register [ENTER]

l         The process works smoothly until it arrives at Activate Dialog.

l         Here I selected Use oen of my existing, active subscriptions.

l         Down at the botton I provide a system name

l         In this case he-serv02

l         When pressing forward 

l         After a few minutes another dialog box appear with:

        ERROR Problem sending hardware profile

hi all...

 

i m trying to do the following...

 

i m going to use static route .. i m writing a program which processes

the incoming packets on one (fixed) ethernet card and forwards it on

another (fixed) ethernet card... i m using PF_PACKET for this

purpose...

 

and  my problem is that along with packets forwarded by my program the

kernel is also forwarding the packets.... so the machine at next hop

gets 2 copies instead of 1...

 

i want kernel to stop processing the packets but i also want it to

pass the packets to my program... i dont even want it to generate ARP

when it does not know the route to destination... i.e. i just want it

to pass the packet to my program and forget everything about

processing the packet on its own...

 

can anyone tell me how to solve this prob??

 

thanks in advance...

 

ashmi
