I have a GuruPlug Server 003-GP0001 running Debian Linux 6.0.3 with FreeRadius 2.1.10 installed. I have followed the Basic Configuration HOWTO<http://wiki.freeradius.org/Basic-configuration-HOWTO>, but when I get to the point of starting the server for the first time, I get this error: Fri Nov 11 18:31:49 2011 : Info: Loaded virtual server inner-tunnel Fri Nov 11 18:31:49 2011 : Info: Loaded virtual server <default> Fri Nov 11 18:31:49 2011 : Error: Failed binding to authentication address 127.0.0.1 port 18120 as server inner-tunnel: Cannot assign requested address Fri Nov 11 18:31:49 2011 : Error: /etc/freeradius/sites-enabled/ inner-tunnel[32]: Error binding to port for 127.0.0.1 port 18120 Can anybody suggest how to fix this issue? The complete output from the freeradius -X command is available: http://pastebin.com/cX3ti0wk Thanks, PaulH
