Destination unreachable

[catherinenayer]

In the following code, I have many issues

1. the stations created didn't appear in the figure
2. when sta11 ping sta12 destination unreachable and also when sta11 ping sta21 all stations connected to different access point isn't reachable
3. cars and stations can not ping to each other also the destination unreachable
4. I have a question about how to add multiple running services to each car in the scenario
5. I have tried to install VND using a web server and when trying to accessing it opens a blank page can you help me with this and thank you in advance

the stations created didn't appear in the figure

It seems that some basics of Python are missing here. Please provide more information about it.

when sta11 ping sta12 destination unreachable and also when sta11 ping sta21 all stations connected to different access point isn't reachable

What is the purpose of nvif=2. Moreover, who is the destination? Ok, sta12 and sta21 are the nodes. However, which network interface are you considering as destination??

cars and stations can not ping to each other also the destination unreachable

Very vague statement :(

I have a question about how to add multiple running services to each car in the scenario

node.cmd() does the work.

I have tried to install VND using a web server and when trying to accessing it opens a blank page can you help me with this and thank you in advance

This is not a repository about VND. VND is not being maintained anymore. Please consider using miniedit instead.

In the following code, I have many issues

Please provide as much information as possible about the issues (if this is an issue). You have opened a generic issue with so many vague questions

As far as I understood, this is not an issue related to the mininet-wifi code. It only concerns questions that can be easily answered with simple searches on the internet or even through the mailing list..
