As far as I know it's not important as it relates to using OP-25. Just be aware that it's part of the operating system, and is supposed to be there. The only reason I even responded to explain this is because you seemed to be bewildered about its presence in your adapter list.

What is a loopback adapter and why does it have a IP address? I apologize if these are dumb questions but I am trying to wrap my head around all of this, and well I'm not doing so good. I have been working on trying to get OP25 and wireshark working today again for the last six or so hours and have not made a dent. I have been working on this project for the last two months now and have gotten almost nowhere. It's just very frustrating and I apologize for all the beginner questions.
Thanks to all for any help you can provide,
Bob

FYI: "lo" is your local loopback adapter (logical only), and 127.0.0.1 is your local loopback IP address.

Does anybody have a working copy of the modified version of wireshark. When I run my version it gives me a option to monitor a interface called lo and has a IP address if 127.000.001 or something similar but I do not see any packets when I monitor it. I still have to get op25 working correctly as well but If anybody can help with a copy of the modified wireshark file though it may give me another starting point.
Thanks to all for any help with this,
Bob

Ok I have wireshark working but it does not capture any packets from the audio input. Now I should add that I haven't gotten OP25 to work correctly yet either I have been going at it all day and have made almost no headway. If anybody can tell me how to capture the data packets from the audio input it would help very much.
Thanks,
Bob

"Ok I tried to get wireshark working with OP25 today using the following command and received the errors below. Any help would be appreciated if I am missing something.
bob@ubuntu:~/src/op25/python$ wireshark dumpcap: There are no interfaces on which a capture can be done dumpcap: There are no interfaces on which a capture can be done dumpcap: There are no interfaces on which a capture can be done dumpcap: There are no interfaces on which a capture can be done"
You need to run wireshark with superuser privileges. This can be done by prefixing the command with "sudo" and typing in your password when asked. So you need to run:
sudo wireshark
and that s hould let you capture on the available interfaces.
