Re: problem to assign source addr port number, instead of random selection

Hi Dave,
        I did some modification to fix local IP address as explicitly.
   
  I bind the agent address with port number in netsnmp_udp_transport(struct sockaddr_in *addr, int local) function.
   
  when i send the Trap to manager, manager can identify the port, which i fixed. I could able to send the ping msg periodically without error.
   
  But i have some problem, when i use get/set cmd from Manager.
   
  when the manager send a Get Request, the agent is receiving the cmd with same Sock Id ( In my case 7 which is used Trap from agent). Its receiving full buf ( Just i verified the buf length).
   
  its giving session version is V2c and Pdu cmd is 160. 

  The manager always is receiving Timeout Error. I do not know in where is the mistake. 
   
  I believe, once we fix the port number with local ip addr using bind system call, it wont change until close the socket. I found that close socket is called, when the snmpd is close.
   
  Give me some idea, how to proceed next. I'm unable to trace out, after finish the _sess_process_packet(void *sessp, netsnmp_session * sp, ....) function.
   
  Please give some idea....
   
  Thanks
   Raju

I don't believe it is possible to set the source port.
