    Re: Wireshark problem

    Hello

    I have the same problem. I'm using a Dell Inspiron 6400 and Ubuntu 8.04.
    Just64 which is your Ubuntu version?
    Thanks for any help.

    Running Wireshark as normal user shows no interfaces. It needs the propper permissions, as running it as root (warning, insecure) or with the tweak found here:

    I'll try it at home tonight.

    if you start wireshark using sudo, do you see it then?

    Code:
    sudo wireshark
    are your doing wireless and not seeing the output?
    You can tell a man who boozes by the company he chooses, as the pig got up and slowly walked away.

    Hello!

    I've just tryed it.
    Yes, running wireshark as root allows me to see all interfaces, but it also is risky.
    Following the instructions given in one the links above works fine. The recommendation was to run command:
    sudo dumpcap -w ./dumpfile
    and later open the file dumpfile with wireshark as normal user so you can filter it as you wish.
    I was just trying to run wireshark on my wired ethernet card. Anyway, I think it has solved my problem.
    And now to study my network activities

    Hello


    You could also capture the output to a file and then open as non root in wireshark for inspection

    Heres how you could do it

    Code:
    tcpdump -w mytrace.pcap -s 1550 -i any port 80
    Where -w defines the output file (in this case mytrace.pcap)
    -s is the the packet size to capture.
    -i is the interface to use, in this case, any, or you could have eth0 etc
    port = limits the capture to a certain port in this case 80.

    You will have a file created when you stop the capture,
    You can then open this with wireshark
    You can tell a man who boozes by the company he chooses, as the pig got up and slowly walked away.
