InboundError EOF

[meling]

Tried to run ogo's l2 switch together with mininet. I first ran ./pox.py forwarding.l2_learning as my controller and set up a basic mininet network (and it worked), and now I want to replace pox with ogo's l2 switch example, but I get:

InboundError EOF

as soon as my mininet network is started. mininet itself seems to not notice any problems at first, but trying to do h1 ping h2 fails with Destination Host Unreachable. This is all that ogo l2 logs:

Ogo 2013
2014/08/13 17:30:16 Listening for connections on 0.0.0.0:6633
2014/08/13 17:30:19 InboundError EOF
2014/08/13 17:30:19 EOF
2014/08/13 17:30:19 Closing OpenFlow message stream.
2014/08/13 17:30:19 Openflow Connection: 00:00:00:00:00:00:00:01

Any hints regarding how to solve this would be appreciated. It seems that the Read from the connection sees an EOFfirst thing. Strange?

Have you tried pinging from both directions? I wrote the l2 example pretty quick, I could have screwed up the logic. You could compare my l2 module against pox's.

I don't think I've ever seen that error right at the beginning of the program. The InboundError usually has to do with the TCP connection going down. This is just a guess, but if you pull up wireshark you'll probably see a TCP fin message sent by one of the devices. I guess it's also possible that the mn switch isn't responding to the hello message fast enough... For the record, what version of mininet (and underlying switch) are you running?
