Please any one can help?
thanks!

do you have any meaningful messages in the ODL karaf.log? Check the switch logs
as well.

I am trying to add DNS over TLS (DoT) protocol to the zgrab2 tool. I used the zgrab2 documentation but I am not able to figure it out. Has anyone added a new protocol that is not there like port 853? ZGrab2 has the common ports but not post 2015.
From my understanding, you need to write your own code for DNS over TLS (DoT) in golang,
and then run an integration test on it. I understand the latter but have no idea how to create a module for port 853.
Would appreciate any suggestions or useful links anyone has. Thanks!
I have set up an SDN using Open vSwitch and OpenDaylight.
I have two machines with Ubuntu and I am using KVM to simulate two devices (for now). I have two other devices in the network. The OpenDaylight Dlux network topology shows an openflow switch and five hosts - the two virtual devices, two real devices and the one machine; the other machine is the one that has ovs and odl and the KVMs.
Now I want to play with flow control... From one of the virtual devices, I can ping the other host/machine - traffic flows from the host through the openflow switch. I am working on setting up a samba server so that I will be able to wget a file from that machine. BUT ultimately, I want to change the flow, so that when I try to download the file, it will instead go from the host through one of the real devices.
I am having trouble locating relevant documentation about how to add/modify/delete a flow using opendaylight (that I can understand). Maybe that last part is the actual problem, but thought I would ask here for some guidance!
if you want to play with flow you have to use opendaylight openflow plugin here the user guide link
http://docs.opendaylight.org/en/stable-oxygen/user-guide/openflow-plugin-project-user-guide.html
you can install postman and send the request to the openflow plugin,,, you can change flow on each port , QOS, flow timeout, ..etc.
I would like to write a network driver for WINDOWS, above TCP.
In this driver I would like to modify or to check "on the fly" the incoming HTTP traffic.
How can I implement a such module ?
Which development environment ? Which SDK ?
Do you know about an open source project which do that ?
Do you think libpcap can do that ?
Thank you for your help.
Sorry I found ... see "Windows Filtering Platform" documentation.
I am running a RabbitMQ instance that provides MQTT over websockets via the rabbitmq_web_mqtt plugin.
For legacy reasons, I need to support a non-default WebSocket URL.
I saw in the documentation it is possible to change the port via the { port, 1234 } config, but I could not find any way to change the WebSocket URL. It is currently set to the default path of /ws
Is it possible to change the WebSocket URL without modifying the plugin?
This has been made configurable back September 2018. See already mentioned ticket.
Add line:
# echo 'web_mqtt.ws_path = /mqtt' >> /etc/rabbitmq/rabbitmq.conf
# service rabbitmq-server restart
Now being accessible by (compliant) MQTT Clients. For instance at:
ws://192.168.210.84:15675/mqtt
UPDATE: RabbitMQ now allows configuration of the WebSocket URL. See this answer.
After some research, I found out that the path is not configurable
OF version:3.9.1, I can use pidgin to log on.
When using strophe.js, I tried BOSH first, but it fails, probably I didn't get apache settings right. Then I decide to try websockets, and this is my preferred option, however, I got the following error message:
WebSocket connection to 'ws://ikan.tk:7070/ws/server' failed: WebSocket is closed before the connection is established.
then the status is "connecting" always.
Questions:
what's the URL for websocket? using http-bind port (7070), or the client port (5222)? Any path (like /ws/server) to be followed ?
I'm using OF 3.9.1 on windows, no plugin installed. Does OF 3.9.1 support WS by default, or I have to install some plugin, or there's some configuration items I need to do?
Thanks in advance!
AFAIK,
1) The URL for websocket on OpenFire is ws://of-server:7070/ws with default configuration (see below).
2) You need to install the "WebSockets Plugin" plugin for OpenFire, then you can configure the path of the websocket ("ws" is default) in properties page under the "Server > WebSockets" tab.
