Hi,
On an Ubunutu 10.04, I tried to
sudo dumpcap -w d1.pcap
which gave me:
The file to which the capture would be saved ("d1.pcap") could not be opened: Permission denied.
according to my naive Linux knowledge, i would have expected "sudo" to give me all the necessary permissions.
What am i missing here?
 
regards,
Lars
