disconnections

[John Fawcett]

I'm using freeradius 1.0.0 on suse 9.2 to authenticate wireless users
from a US Robotics USR5450 Access Point via eap-ttls (with eap-md5)

Although the connection is established it is disconnected after 4
minutes (sometimes 2 minutes or 6 minutes). I get entries like the
following repeated every four minutes in the radius.log

Mon Jun 20 00:37:59 2005 : Info: rlm_eap_tls:  Length Included

Just a couple of more points:
I don't think the TLS_accept: error is serious.
I cannot explain why there are two Auth Logins one from the NAS and one
from localhost.

Any help appreciated. I somehow get the impression that I'm probably not
passing back the right attributes to the NAS: for testing I'm using the
users file:
steve   User-Password == "testing"
    Framed-IP-Address = 192.168.1.67,
    Framed-IP-Netmask = 255.255.255.0,
    Service-Type = Framed-User

Thanks
