<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2> I am using RedHat 9.0 and am
working on implementing an IGMPv2 testing tool. My test setup includes a machine
"172.16.7.10" on which the daemon "mrouted" runs and another mahcine
"172.16.7.9" on which the testing tool runs.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I am trying to read IGMP packets
on machine "172.16.7.9" using raw sockets. But to my surprise only the general
queries generated by mrouted running on "172.16.7.10" are being read by the
raw socket. The reports generated are being skipped. I know that reports are
being generated because of tcpdump which I am simultaneously running on
"172.16.7.9" which shows IGMPv2 reports as well.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Now my question is simple - if
the program which i have written using raw sockets can read General Queries, why
isnt it reading Group specific queries and reports ? Should I set any
socket options or should I subscribe to any group so that all queries and
reports are passed to the raw socket ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In anticipation,</FONT></DIV>
