[SNMP4J] RE: SNMP4J Digest, Vol 34, Issue 10

[Shanmugam Vairavan]

Hi

	Iam also facing the same problem.
	If I put everything on a thread and at some point I call the running

	thread wait() it seems the snmp object does not receive anything! 

Any idea?
Thanks

Hi again and I am sorry for my multiple questions!
I am trying to understand the internal threading mechanism of the Snmp 
mechanism.  I want to make an SNMP object to send multiple get requests 
(using the same instace- for loop) and the asynchronously wait for the 
replies. How can I make the whole thing last for a certain period
I mean while sending the snmp object receives the requests I want to 
keep it alive for another 5 seconds. So ..I have 5 seconds to send my 
commands and if I complete this task early ..wait.
If I put everytjing on a thread and at some point I call the running 
thread wait() it seems the snmp object does not receive anything!

Any tips?

Thanks

OK, I have added

   public static final int DEFAULT_COMMAND_RESPONDER_PORT = 161;
   public static final int DEFAULT_NOTIFICATION_RECEIVER_PORT = 162;

to SnmpConstants.java.

Best regards,
Frank

Hi,
 
I have some tables that I need to instrument dynamically when a request
from a manager is received to have the most up-to-date information. A
related example would be to exec an 'arp -a' to dynamically obtain the
ARP table. What is the appropriate way to do this in SNMP4J-Agent, for
the moment assuming that calling some external command like an 'arp -a'
is fast enough? 
 
Can I do this at the moment a request is received (by overriding a
getValue() for example) or do I have to have a separate thread
monitoring the ARP table and creating and deleting rows in the table
accordingly?
 
Thanks!
 
Arnoud.
