To my knowledge, wireshark and libpcap's capture mechanism is pretty
solid for USB and network captures on 11.10. The bug is most likely in
one of your kernel drivers, so I would suggest opening a bug against the
kernel with "ubuntu-bug linux". The kernel devs may tell you to send it
back to wiresh
Bug is reproduceable on Ubuntu 11.10 64-Bit for me. Live Capture results
in a kernel panic in root & user mode before and after I changed the
permissions according to http://wiki.ubuntuusers.de/wireshark.

Significant new versions of wireshark and libpcap have been added to
Ubuntu since the last time this bug was touched. Marking as incomplete
until someone can show that it is still reproducible on a recent

The current libpcap has several issues with usb capture.
There is a new one upstream that will hopefully be in lucid in a few
days.
Once that's in, I'll post here and if someone could try and reproduce it
on Lucid that would be great.

kernel panic when live capture started

Of course it's a kernel bug, no matter what an application does it shouldn't be
able to crash the kernel unless it's explicitly trying to do so. On that note,
I tested this against kernel.org a while back and didn't have the problem (with
the intent of adding it to the kernel bug tracking syste
It may be the problem reported here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=541227
or here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=568725
It's probably a kernel bug.

I'm going with my gut and calling this a wireshark bug, not a libpcap
bug.
The workaround alters the permissions for dumpcap, which is part of
wireshark.

Michal Matyska, big thanks!!!:
1. sudo apt-get install libcap2-bin
2. sudo setcap cap_net_raw=+ep /usr/bin/dumpcap
It's really working!!! (I hope, this will be a temporary solution)

I also tried start capture without promiscious mode... does not help.
When clicked on Capture Options, the capture dialog appears and the system is
locked before the capture even starts...
Tcpdump works correctly.
