SO_REUSEPORT and multicasting

SO_REUSEPORT and multicasting

[Jason]

Hello,

I wrote a program that uses multicasting to send data.
 It works great on HP-UX but does not work on Fedora
Core 5.  I emailed the fedora list but they were of
little to no help.  

Does the kernel support SO_REUSEPORT?  If so can
anyone give me some suggestions why my program does
not work on Linux?  I did a route add -net 224.0.0.0/4
dev eth0 but that did not do anything.

I have found out since I posted this message to
linux-kernel that SO_REUSEPORT is a BSDism.  The Linux
equivalent is SO_REUSEADDR which I did try.  My
program compiles cleanly using SO_REUSEADDR, but the
server does not receive any messages.  

I am trying to run the client and server on the same
PC.  This is just for faster development.  I can code
faster on my home Linux system than I can on the
remote HP-UX system.

Thanks,

If you can send me (or post) the program, I may be able to help.
