Forum Topic - How to tap /dev/slog: (3 Items)
   
How to tap /dev/slog  
 I need to detect ip conflict on my QNX based networking system
 
 I tried reading /dev/slog and got 
 
  “duplicate IP address 128.0.0.3 sent from link address 00:21:70:d2:af:34”  into slog.

 1) Need to know how this gets filled and by whom?
 2) Is there any way to directly get hold of ip conflict
 
 Also 
  “npm-qnet(L4): lr_inbound(): rxd pkt type 2 with duplicate name/domain, staying online”. gets in slog when there is 
any other conflict on the network
  

   
  
RE: How to tap /dev/slog  
The tcpip stack seeds the 'duplicate IP ..' message.
You can get the count from 'netstat -parp | grep duplicates'
but you don't get the addresses.

Not sure about qnet.

Re: RE: How to tap /dev/slog  
Thanks for the reply but then I need to know exactly when TCP stacks seeds it?

Is there any other way we can get directly ip conflict issue from TCP
