<div>Are you sure your system is listening to multicast on the correct interface(s) ? </div>

<div>Here in my configuration I have two spread daemons running on my server farm.on two seperate spread segments</div>
<div>The following output should be the same across all your nodes in the spread group. </div>

<div>hi Adam,</div>
<div> please try to shut down the firewall on each computer.</div>
<div> I met the same problem when I tried to comunicate 2 machines with spread(spuser) the day before yesterday.</div>
<div> I shut down the firewalls this morning(HongKong time, haha), problem solved! </div>
<div> I subscribed to user-list for 3 days and I received this letter(see ----Forwarded message----below) this morning. I reply directly to you as soon as possible, wish this letter can help you.</div>
<div> I am new to spread, too.</div>
<div> I use OS: redhat enterprise linux AS 4.</div>
<div> cmd: #service iptables stop</div>
<div> </div>
<div>best wishes</div>

To: <a href="mailto:spread-users@lists.spread.org" target="_blank">spread-users@lists.spread.org</a><br>Message-ID: <<a href="mailto:f83ac561f61.484e77f2@wiscmail.wisc.edu" target="_blank">f83ac561f61.484e77f2@wiscmail.wisc.edu</a>><br>
Content-Type: text/plain; charset=us-ascii<br><br>Hello<br>I'm new to spread, and I'm doing some experimenting to get a couple computers to talk to each other.<br>I can run the daemon just fine on each machine separately, and have different processes send and receive messages between each other (using spuser, as well as a simple program I wrote to get used to the C API).<br>
The problem occurs when I try to get the daemons to recognize each other.<br>Here is what my config file looks like (identical on both machines):<br><br>Spread_Segment <a href="http://128.104.165.255:4803/" target="_blank">128.104.165.255:4803</a> {<br>
machine1 <a href="http://128.104.165.48/" target="_blank">128.104.165.48</a><br> machine2 <a href="http://128.104.165.47/" target="_blank">128.104.165.47</a><br>}<br><br>Both daemons load successfully, but I get the following message on machine1:<br>
<br>Configuration at machine1 is:<br>Num Segments 1<br> 1 <a href="http://128.104.165.255/" target="_blank">128.104.165.255</a> 4803<br> machine1 <a href="http://128.104.165.48/" target="_blank">128.104.165.48</a><br>
<br>and a similar message on machine2 with the corresponding IP.<br>Then when I run spuser, the machines don't seem to recognize that the other exists.<br>Any ideas would be greatly appreciated.<br><br>Thanks in advance!<br>
