Re: [Discuss-gnuradio] Socket PDU: Host not found (authoritative)

[Alex Weihkopf]

Maybe I found the mistake. I think it's a bug.

I have to mention that the computer I'm working on has no internet connection.

Hmm,

 

I checked it. There's not typo. And I can ping 127.0.0.1.

 

What I am trying to do is to use PDUs for transmitting a video stream. My OFDM receiver first demodulates data from USRP, constructs a PDU which then is send to VLC player via socket_PDU. At least that's the idea.

 

But I can't start the socket_PDU. I could transform the received bits to bytes and use UDP_socket instead of socket_PDU. I guess the result would be equivalent. But I want to use PDUs. (The socket_PDU takes the PDU's payload and sends it via socket, rigth?)

 

Also, I can send random data from UDP_sink to UPD_source, but I can't send random data from socket_PDU to UDP_source.

Hi Alex,

This looks like a DNS error. I don't know what OS you are on, or why
the udp_source tries to lookup the name instead of just taking it as
an IP address. My guess is a typo, something like a comma in place of
a dot between the numerals...

In the rarest configurations something could have gone wrong with your
loopback device, so that there is no 127.0.0.1; you should be able to
check that using "ping 127.0.0.1".

Greetings,
Marcus
