Hi, We use freeradius to authenticate some Network Equipment, wie Router, Switches, usw.. and all run well! # radiusd -v radiusd: FreeRADIUS Version 2.1.8, for host x86_64-suse-linux-gnu, built on Sep 2 2010 at 13:07:57 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. You may redistribute copies of FreeRADIUS under the terms of the GNU General Public License. For more information about these matters, see the file named COPYRIGHT. Now, I'm using "nagios" to check servers and network and I want to check up the freeradius server. So, I've install freeradius on a Linux machine and try to connect to the freeradius Server but It doesn't run : # radtest nagios nagios 10.28.8.133:1812 1812 outrider Sending Access-Request of id 120 to 10.28.x.133 port 1812 User-Name = "nagios" User-Password = "nagios" NAS-IP-Address = 127.0.0.2 NAS-Port = 1812 Sending Access-Request of id 120 to 10.28.x.133 port 1812 User-Name = "nagios" User-Password = "nagios" NAS-IP-Address = 127.0.0.2 NAS-Port = 1812 Sending Access-Request of id 120 to 10.28.x.133 port 1812 User-Name = "nagios" User-Password = "nagios" NAS-IP-Address = 127.0.0.2 NAS-Port = 1812 radclient: no response from server for ID 120 socket 3 1) I don't know what's the NAS-IP-Address? 2) I don't find any right document about "how to configure the client"? 3) How should I configure the client? Should some deamon to be start? Any help would be appreciated and thanks in advance, Best regards Freundliche Grüsse _________________ Jérôme M.
