[op25-dev] OP25 and WireShark Help

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 at 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.
