radutmped is a utility that can remove utmp entries from the radutmp files of several RADIUS servers. It directly manipulates the radutmp file and does not use radzap or any other programs. FreeRADIUS, Cistron Radius Server, and GNU Radius radutmp formats are supported. Three search modes are available: radutmped can match entries in radutmp by login (User-Name), nas_port (NAS-Port), or session_id (Acct-Session-Id).
Sescle will automatically remove PHP session files if they have not been modified for longer than the 'garbage collection timeout'. This can help aleviate high-load situations where PHP itself cannot be relied on to remove expired sessions, or in a high-security environment where sessions containing sensitive data must be removed in a timely fashion. It requires Linux >=2.6.13 and Glibc >=2.4.
