Hello everyone
I just downloaded wireshark 1.0.0 on my Mac Book Pro and I have Mac OS X 10.5.2
I do not see any interface in dropdown list and when I type interface name such as "en0" or "en1"
I get below mentioned error:

     The capture session could not be initiated ((no devices found) /dev/bpf0: Permission denied).

     Please check to make sure you have sufficient permissions, and that you have the proper interface or pipe specified.
While its working fine on windows platform.
Can anybody help me why its happening so.

Thanks

Regards
Tarun
