[Ethereal-users] tethereal syntax question

["David Wood" <dwood@xxxxxxxxxxxxx>]

I have run into a problem with trying to set up a capture using tethereal.  I would like to it up so that I get a revolving 24 hour capture, in 30 min increments.  While this is simple in Ethereal, in practice with tethereal (I only have a command line interface on this particular server) it is not working.  My initial attempt was:

 

tethereal -w file.foo -a filesize 100000 -b 48:18000

 

In practice, after the initial file capture of 100 MB, I got 48 tiny files that continued to overwrite themselves.  I have tried all sorts of variations on the -b option, and I can not get any of the ring buffer files to be over 124kb

 

According to the man pages on this server, I am using v 0.99.  Is there a bug with the -b option?  Do I have the syntax incorrect?

 

Any assistance would be greatly appreciated.

 

Sincerely,

 

David Wood
