<P><FONT SIZE=2 FACE="Arial">Hello,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I am new to Freeradius. I am running Freeradius 2.1.0 on Ubuntu 8.10, built from source.</FONT>
<BR><FONT SIZE=2 FACE="Arial">I have already read all the documentation I could find in the config files and in the wiki.</FONT>
<BR><FONT SIZE=2 FACE="Arial"> </FONT>
<BR><FONT SIZE=2 FACE="Arial">The machine has two network interfaces, eth0 and eth1, the first configured with ipv4 and the second with ipv6.</FONT>
<BR><FONT SIZE=2 FACE="Arial">I am interested on using freeradius with ipv6 support so I would like to test it using it only on eth1 interface.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">The point of my testbed will be to define a new attribute and transfer it to the client when it is authorized. </FONT>
<BR><FONT SIZE=2 FACE="Arial">But before doing it I am finding some problems in opening the ip6 socket in the server. </FONT>
<BR><FONT SIZE=2 FACE="Arial">In fact I configured users and clients.conf to allow my ip6 client to connect to the server, and then in the radiusd.conf file I commented the ip4 listening option and uncommented the ip6 one. (I also commented the accounting listening part because I am not interested in it).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">The problem is that when I run the server it exits saying (last lines):</FONT>

</P>
<BR>
<P><FONT SIZE=2 FACE="Arial">I checked if the ip6 interface is properly configured, and it seems so (i can ping other ip6 nodes, and also writing another little c program to bind an ip6 socket works fine)</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Changing port doesn't solve the issue.</FONT>
<BR><FONT SIZE=2 FACE="Arial">Commenting or uncommenting the "interface" line in radiusd.conf doesn't change anything.</FONT>
<BR><FONT SIZE=2 FACE="Arial">Trying different types of ip6 addresses (::1, or manually assigned ones) doesn't work either.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Obviously with ip4 I don't have any kind of problem.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I can't understand if it a freeradius configuration problem or a system configuration one.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Thank you for you help!</FONT>

<P><FONT SIZE=2 FACE="Arial">Regards,</FONT>
