Re: Capturing without having superuser rights

[Damien ANCELIN <damien.ancelin () ens-lyon fr>]

To give you more informations :
- "metrology platform" will be a computer that can be used by many 
users to capture packets (coming from a mirroring port of a switch).
- It's currently running on an linux debian.

It seems there is no common manner to do this in a simple way (I will 
have a look on that kernel patch).

Thanks for your help
Damien
