Subject: TFTP send issue 2.0
Importance: High
Hi,
I am using commons net 2.0 version. I have a TFTP server implemented
and the scenario is below -
1) Client sends TFTPWrite request.
2) Server sends DATA packet, client sends ACK. Server receives it (thr
TFTP.receive()).
3) This goes well for quite some time.
4) Now server gets same ACK thrice, means some packets are not reached to
client and client sends the same ACK again.
5) Server also sends the old DATA packet coresponding to the ACK, using
TFTP.send(). But somehow those DATA packets are not seen on the interface in
the snoop log :(. So client has a timeout of say 5 secs, and closes the
connection at its end indicating overall transfer failure. And I could see the
DATA packet coming in the snoop log after 13-14 secs of delay :(, once
TFTP.send() is invoked.
Any clue why this could happen? Any help is appreaciate?
Regards,
Rahul
