Wireshark · Wireshark-users: [Wireshark-users] Problem with capture ring buffer option

["Christelle VANDENENDE" <cvandenende@xxxxxxxxxxxx>]

Hello,

 

 I am using ethereal (0.99). Sorry.
I need to make a capture using tethereal.
I just want to generate a new capture file every 15 secondes, so I have written this :

 

tethereal.exe -b duration:15 -i 1 -w test.cap -f http

 

It doesn't work. It generate this message :
"tethereal: Multiple capture files requested, but no maximum capture file size was specified."

 

If I add the option "-b filesize:10", the duration is not "used".

 

I probably do something wrong but ...

 

Thank you for your help.
