Hi, Dear all,
I have two issues about linc-swtich and Ryu.
1. I installed linc-switch in the Raspberry pi devices in Dec. 2013, and
Ryu controller in a PC. The linc-switch can connect to the controller, and the
Ryu controlled the linc-switch well.
I connected a host to a server through the linc-switch, and added the flow
table to the linc-swith by the Ryu controller. The commands are as follows:
curl -X POST -d '{
"dpid": 202481586003128,
"cookie": 1,
"cookie_mask": 1,
"table_id": 0,
"priority": 11111,
"flags": 1,
"match":{
"in_port":3
},
"actions":[
{
"type":"OUTPUT",
"port": 2
}
]
}' http://localhost:8080/stats/flowentry/add
curl -X POST -d '{
"dpid": 202481586003128,
"cookie": 1,
"cookie_mask": 1,
"table_id": 0,
"priority": 111111,
"flags": 1,
"match":{
"in_port":2
},
"actions":[
{
"type":"OUTPUT",
"port": 3
}
]
}' http://localhost:8080/stats/flowentry/add
I can ping the host and server each other. But when I accessed the server, it
always automatically downloaded the html file. If I connected directly the host
to the server, it worked well.
2. I’m not sure if the reason is that the linc-switch version is old, so
I want to update it. While I updated(reinstalled) the latest linc-switch in the
Raspberry pi in Jan. 2015, there is an error like this:

Could you give some support?
thanks a lot!
