Hi,
i try to capture with tethereal in ring buffer mode. I tested it first 
on a Debian which was working fine like this:
# tethereal -a filesize:5000 -b 10 -i eth1 -w testfile
On gentoo i can't get it run. After fulfilling the given criteria of 
5000kB tethereal jumps to next file BUT ignoring given filesize which 
finally looks like this:
ls -la
total 92

Obviously the 1st 5000kB file was overwritten :). This is the command 
line used on gentoo:
# tethereal -a filesize:5000 -b files:10 -i eth1 -w testfile
Is this a bug on gentoo or is there a mistake in my command line?

p.s.: installed version:
tethereal -v
Tethereal 0.99.0
0.99.0 had some bugs in the ring buffer mode:

Try upgrading to 0.99.2 (Wireshark).
