Ethereal-dev: [Ethereal-dev] Need Urgent Help - Maintenance of Tethereal state information
Hi,
It appears that tethereal/ethereal maintains state information ( in some
specific circumstances ) as per an earlier message of the mailing list
(http://www.ethereal.com/lists/ethereal-users/200211/msg00022.html).
I quote Ronnie Sahlberg
">>>>> .... The state in question is the stuff ethereal remembers internally
about every packet it sees, information such as when the packet was received,
size of it,
>>>>> .... every packet will still add to the state buildup inside ethereal
until you reach a point where memory is exhausted.I.e. ethereal will become
slower and slower as memory is exhausted on the system.
>>>>>>.... Stoping and restarting the capture is an efficient method to
control the amount of state buildup. "
In our usage scenario , the packets need to be captured for long durations of
time at a stretch ( maybe months , may even be years ) and therefore memory
exhaustion may not be acceptable ,
1. Is it possible to CLEANUP the STATE INFORMATION when switching between
capture files in the ringbuffer ?
2. If yes , Which function calls can be made to cleanup such state
information ?
3. Stopping and restarting capture as suggested above would not be viable as
that may involve the undesirable missing of a few packets . Is there any
other possible technique to cleanup the state information ?
Thanks ,
Amit Vashisht
