Clvc client cannot connect to server

[mariosavior]

Hi all,
I was working with vanet.py and when I run it, the two vlc screens in which you can see the video sent by the server and that same video when the client receives it, do not appear.

When I noticed this, edit the code adding the following lines before the server sends the video (cars [0] .cmdPrint ()) in order to kill possible vlc process running and also to allow all users to use vlc as root. Well, with these two lines, I got to watch the server vlc screen, but not the client one:
-os.system ("pkill -f vlc")
-cars [0] .cmdPrint ("sed -i 's / getuid / getppid /' / usr / bin / vlc")

Trying to fix this situation, I stoped the execution just before client (client.cmdPrint ()) and opned a terminal of "xterm client". Once inside of xterm I tried to run the same commands:
-sed -i 's / getuid / getppid /' / usr / bin / vlc
-cvlc rtsp: //200.0.10.100: 8080 / helmet.sdp &

and this is the error output in client xterm:

I cannot make a "client ping car0" neither. It says "Network is unreachable"
Why the client cannot connect to the server?

Hi,

I'm porting the code to the newest version of Mininet-WiFi on branch beta. The routing table still have to be fixed.

[ederollora]

Can we move to a specific commit so that the table is still working?

[ramonfontes]

You should try the last commit from the master branch of the mn-wifi repo and the beta branch of this repo.

Hi again,

I pulled from Mininet-Wifi master branch and checked out beta brunch in this repo as you said. The problem is the same. Only one of the screens appears, and I believe is the Server one, because I stopped the execution just before the "applying second rule"stage and opened a terminal of the client. Once inside of xterm I tried to run the same commands and the error was again:

In addition, I tried again to ping car1 from client, and it was also unreachable.

Could you try it out yourself and let me know if you experience the same errors?

Thanks

I just updated the readme and I added information regarding the commit from Mininet-WiFi you need to use.
