<p class=MsoPlainText>Hi guys<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I have similar issues like this and what I find is that I
need so specify the "real" ip address as the first host entry. This
is the case for the multicast beacon and a number of others things, so as
something I do with all my Linux machines is that I do the following (Please
note that these notes are taken directly out of my install guide which can be
found at <a href="http://www.accessgrid.org/node/1133">http://www.accessgrid.org/node/1133</a>):

<p class=MsoPlainText>I think I'm having the same problem. But won't this
solution only work <o:p></o:p></p>
<p class=MsoPlainText>if you have a static IP address (or your dhcp server
gives you the same <o:p></o:p></p>
<p class=MsoPlainText>address every time)?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Seems like I could specify a hostname in
/etc/network/interfaces like:<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>auto eth0<o:p></o:p></p>
<p class=MsoPlainText>iface eth0 inet dhcp<o:p></o:p></p>
<p class=MsoPlainText> hostname eth0name<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>But that doesn't seem to work.<o:p></o:p></p>
