<P>
Hi ,<BR>
<BR>
Thanks to all for the response.<BR>
<BR>
I made=
changes In fragment.seq and now script is working fine.<BR>
<BR>
one m=
ore problem is there.<BR>
<BR>
My TN is sending a packet<BR>
<BR>
v=
Send(Link1,echo_request_LINK1_v4_tn2nut_OFFLINK)<BR>
TN(Offlink address) =
--ICMPv4 Echo Request (size 1450)-->NUT<BR>
<BR>
and it is expecting=
<BR>
vRecv(Link1,echo_reply_LINK1_v4_nut2tn_OFFLINK)<BR>
TN(Offlink ad=
dress) <--ICMPv4 Echo Reply (size 1450)--NUT<BR>
<BR>
the problem is=
that while sending DF bit is SET,and while receving DF is NOT SET.<BR>
c=
an anyone pls tell me that is it necessary that DF should be<BR>
set in r=
eply??<BR>
or in other words is it nessary that DF bit should be same in<=
BR>
ICMP ECHO REPLY in a response to ICMP ECHO REQUEST??<BR>
<BR>
