Hi, Mahmoud
Please confirm you've ran your apps with "--observe-links" option.
Without this, host detection won't work.
If the above does not solve your problem,
please tell me commands you ran to run your apps and to make ping.
Thanks,
Fujimoto

Hi, Mahmoud
First, rest_topology.py can find hosts only after the controller
catch the packet from hosts.
OTOH, by the default, rest_firewall.py drops all packets at the
switch.
So, rest_topology.py could not find any hosts, because it catch no
packet from hosts.
To find hosts, you need to:
* enable the switch in order not to drop all packets

<https://osrg.github.io/ryu-book/en/html/rest_firewall.html#changing-in-the-initial-state>
* send packets from hosts in order to notify the host exists

Hi, Mahmoud
Sorry, but I can't solve your problem without more information.
I want to know how you ran apps, it is needed to reproduce
your problem.
So, could you tell me the command which you ran?
And, what "doesn't work" means?
It replies with empty list, or responds with 404?
It is helpful for me to tell me the response from
rest_topology.py.
Thanks,
Fujimoto

Rest_topology.py module help me to get all hosts ' s mac
address and ipv4 address by using rest request
(http:/localhost:8080/v1.0/topology/hosts
<http:/localhost:8080/v1.0/topology/hosts>).
My problem is when i run Rest_topology.py with
simple_switch.py it works fine and get all hosts' s mac
address but when I run Rest_topology.py with
rest_firewall.py It doesn't work.

Hi, Mahmoud
Sorry, I couldn't reproduce your problem...
For further inspection, could you tell me the following? :
* The command which you ran
* Log messages of Ryu with '--verbose' option
* Diff of rest_firewall.py, if you modified
rest_firewall.py
Thanks,
Fujimoto
