[Discuss-gnuradio] Problem with udp-sink/source over a network

[Dev Ramudit]

Hello all,

   I've been working with the udp-sink and source blocks to try and get 
a usrp working from a remote location. Everything I've tried seems to be 
working fine when I test on a local machine, but I'm getting an odd 
error once I move to a remote test. I used the vector_source.py and 
vector_sink.py as examples for what I have so far, and going back to 
them it seems like they don't work for me remotely either. I get the 
following error when attempting to connect my own application and 
vector_source.py to a remote computer:

socket connect: Invalid argument
terminate called after throwing an instance of 'std::runtime_error'
 what():  can't connect to socket
Aborted

I can't for the life of me figure out what the invalid argument going to 
connect() might be. I've attempted to use gdb as per the recommendations 
in "How to Write a Block", but after attaching to the process gdb is 
unable to figure out where it is, and stepping through the code doesn't 
work at all. If anyone could try running vector_source/sink.py on remote 
systems, I would greatly appreciate any help getting this working. Thanks!
