[ns] Re: Unable to send packets downstream

[Manoj Kumar Chinnakotla <manoj@it.iitb.ac.in>]

hi,

i did some experiments on the RTP and RTCP Agents and found that the
RTCP Agent can send packtes only in "Multicast mode" and fails to send
packets when it is in "Unicast mode"....

In unicast mode, it fails at target_->recv(p,0) line in the
sendpkt() procedure in rtcp.cc...A "segmentation fault" occurs at this
point..

can anybody please explain me the reason behind this and suggest how to
overcome this problem...

thanks in advance,

Manoj Kumar.
