OK. Sorry for assuming that some people could be conversant on this issue. VNUML stands for "Virtual Network User Mode Linux" (http://jungla.dit.upm.es/~vnuml/) a tool to simulate networks and hosts (virtual machines) in linux. The result is a near physical network with all its features... each machine with its filesystem, interfaces, e.t.c. I am in the process of building a radius server and some firewalls in these simulated networks... To the original question: How do I configure freeradius to recognize the nets and hosts created by VNUML ? Radtest receives an Accept-Accept with localhost, but keeps sending access-request for a long time. xxxxxx@linux:~> radtest steve testing routerA localhost testing123 Sending Access-Request of id 246 to 10.0.10.2:1812 User-Name = "steve" User-Password = "testing" NAS-IP-Address = linux Re-sending Access-Request of id 246 to 10.0.10.2:1812 User-Name = "steve" User-Password = "W\272\327Mr":\275\251\223;\206\264\005\3657" NAS-IP-Address = linux : : Thanks in advance, mfG, Trüffel ___________________________________________________________ Gesendet von Yahoo!
