1. there is no hello reply from openflow:

2. and i think i am using openflow 13:

screenshot from 2015-08-22 11 53 57

so what is wrong??

by the way, my ODL works fine with mininet. [i am not sure i am using openflow 13 on mininet] and i compiled the code with the latest openwrt.

And another question whyopenflow is making connection to 127.0.0.1 ?

hojatm-huma commented 9 years ago

I solved my problem this way: I was using the latest version of openwrt Chaos Calmer, and i think this was making this error:

Aug 18 11:25:38|00057|vconn_stream|ERR|connection dropped mid-packet

so i went to latest stable version BarrierBreaker, mentioned problem solved but still connection droping exist.

I found that in any time you want to connect to controller you need te restart openflow

/etc/init.d/openflow restart

, even in newly booted os.

BUT still i dont know why openflow is trying to find controller locally ( 127.0.0.1)!
