<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Our beowulf cluster has recently got channel
bonded on the latest kernel 2.2.15. </FONT></DIV>
<DIV><FONT face=Arial size=2>Everything seems okay except the </FONT><FONT
face=Arial size=2>IP multicasting. </FONT></DIV>
<DIV><FONT face=Arial size=2>By "tcpdump -i bond0"</FONT><FONT face=Arial
size=2>, I find the </FONT><FONT face=Arial size=2>multicast packets do reach
the related nodes.</FONT></DIV>
<DIV><FONT face=Arial size=2>But the application can not always receive the
corresponding packets. Most of</FONT></DIV>
<DIV><FONT face=Arial size=2>packets are dropped. </FONT><FONT face=Arial
size=2>It happens when I connect a socket to a MC group, and </FONT></DIV>
<DIV><FONT face=Arial size=2>then use send. </FONT><FONT face=Arial
size=2>When I use sendto and specify group/port, things work fine.
</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Any comments are appreciated.<BR><BR>Thank
you.</FONT></DIV>
