>Description:
Athlon 700 socket, Intel 10/100 PCI (FXP).  Running Cistron 1.6.3 radius and Lucent PM3 w/ comos 3.9.1
Repeatedly posts "NAS_port_type".  Somewhere around 4.3 -> 4.4 change the problem manifested itself by causing grep to swell to 500+MB.  An open tcpdump will show:

13:59:25.471963 pm1.intrastar.net.1026 > moon.intrastar.net.1646:  rad-account-req 194 [id 47] Attr[  Acct_session_id{3500B78C} User{sandyland} NAS_ipaddr{pm1.intrastar.net} NAS_port{26} NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type NAS_port_type

It will repeat the NAS_port_type "forever"
>How-To-Repeat:
For me all I have to do is tcpdump an ethernet segment with radius traffic.  I have not been able to change radius servers to see if its a server related issue.

>Fix:
working on that...

 Jacob,
 
   Can you capture me a couple of these packets?  Maybe use something
 like "tcpdump -c 2 -w badpkts udp port radius" and send me the
 "badpkts" file, after verifying that "tcpdump -r badpkts" causes
 the loop?
 
 Thanks,
   Bill
