[nn] reason : close age out

["Arno MESGUICH" <arno.mesguich@noxs.fr>]

Hi everybody,

 

i need to understand the signification of age out :

 

479729521 126.0.14.66 discard-debug 2007-02-21 11:08:45 fwname: NetScreen device_id=fwname [VSYS_FW]system-notification-00257(traffic): start_time="2007-02-21 07:50:17" duration=12163 policy_id=4 service=tcp/port:5030 proto=6 src zone=Untrust-VSYS_FW dst zone=Trust-VSYS_FW action="" sent=36566 rcvd=122370 src="" dst=126.9.241.120 src_port=1934 dst_port=5030 src-xlated ip=126.16.98.119 port=1934 dst-xlated ip=126.9.241.120 port=5030 session_id=461068 reason=Close - AGE OUT00

 

On this firewall, admins set the main tcp timeout to 5 hours !!!!!

I just want to undestand the meaning of age out, and the difference with reason : close - FIN

 

Thanks for you help.
