[arch-general] Error in wireshark-gtk2 in show interfaces for capture

[Maykel Franco]

Hi, I have installed wireshark-gtk2. But when go to Capture/Interfaces
I get this error:

There are no interfaces on which a capture can be done.

I follow this steps:

Setting network privileges for dumpcap

1. Ensure your linux kernel and filesystem supports File Capabilities
and also you have installed necessary tools.

2. "setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap"

3. Start Wireshark as non-root and ensure you see the list of
interfaces and can do live capture.

Limiting capture permission to only one group

1. Create user "wireshark" in group "wireshark".

2. "chgrp wireshark /usr/bin/dumpcap"

3. chmod 754 /usr/bin/dumpcap

4. "setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap"

5. Ensure Wireshark works only from root and from a user in the
"wireshark" group


Thanks in advanced.
