AttributeError: 'Mininet' object has no attribute 'addStation'

AttributeError: 'Mininet' object has no attribute 'addStation'

[ramonfontes]

Hi,

Probably there is something wrong in your installation. Have you run "make install" inside of Mininet-WiFi's root directory? Which version do you have installed (mn --version)?

[maganiss]

No I had not run "make install" but now I did it and nothing changed.
sudo mn --version output was:

1.6r3

[ramonfontes]

It is weird. You should be able to run any example. This error normally occurs when you do not have it properly installed. (if you look at https://github.com/intrig-unicamp/mininet-wifi/blob/master/mininet/net.py, the attribute addStation is there). Do you still have the same error?

[maganiss]

Yes, I have the attribute addStation in my net.py, and I have the same error.

[maganiss]

I have an earlier installation of mininet (not the wifi version) in another directory.
Do they have conflict with each other?

[ramonfontes]

No no.. they do not have conflict, but it is not possible use both together. If you have run make install in Mininet-WiFi, you will use only Mininet-WiFi (but it has the same properties of Mininet). On the other hand, if you run make install in Mininet you will use only Mininet. You can see the difference with mn --version. Although I do not believe it has any error, I am going to install it from scratch in a new machine and let you know about the results.

Hi,

I've just installed it and it is working properly. :( I am curious about this problem.

[maganiss]

I installed mininet wifi in a fresh Ubuntu 15.10 machine without any other installations on it.
Again, the default topology runs (with sudo mn --wifi --ssid=new_ssid), but by running "sudo python examples/wifiPosition.py" or any other examples, I face the following error :

me@ubuntu:~/mininet-wifi$ sudo python examples/wifiPosition.py

[ramonfontes]

Run mn -c, and then your scenario.

sudo mn -c worked for me in my fresh ubuntu 15.10 .
(although ubuntu 14.10 still fails).

Thanks a lot.

[ramonfontes]

If the error says: Cannot find device "wlan", sudo mn -c should works in any case and any Ubuntu distro. But if the error message is "AttributeError: 'Mininet' object has no attribute 'addStation'", something is wrong in the installation process or there is something strange that I did not know until now. I will continue to investigate to comprehend what is happening.

Hi, did you ever get the solution to this issue? "AttributeError: 'Mininet' object has no attribute 'addStation'"

I am getting the same issue. I have run make install in the mininet-wifi directory, and then run it again but it still gives me the same error.

[sahilabro]

FYI

mn --version

2.2.0d1

[sahilabro]

It does not this give me the error if i remove stations and APs, it works for Controller and Host, so perhaps it's an issue with it using Mininet not mininet-wifi?

[ramonfontes]

Please try: mininet-wifi$ sudo rm -r /usr/local/lib/python2.7/dist-packages/mininet* Then run: mininet-wifi$ sudo make install

Hi, it still gives me the same error after removing the directory and reinstalling from within the mininet-wifi folder.

mininet-wifi$ python test1.py
mininet-wifi$ Traceback...

[ramonfontes]

According your version (2.2.0d1), you have Mininet and not Mininet-WiFi. I suggest you to review the installation process.

Hi,

I see. When I run
$sudo mn --wifi

It works fully well, with two stations and one AP. Does this still mean I have mininet not mininet wifi?

Nevertheless, I tried again by removing instances of mininet and reinstalling mininet-wifi:

i.e

sudo rm -r /usr/local/lib/python2.7/dist-packages/mininet*
sudo rm -r /usr/local/bin/mn
sudo apt-get autoremove mininet
sudo apt-get autoremove mn
sudo rm -r mininet-wifi
git clone https://github.com/intrig-unicamp/mininet-wifi
cd mininet-wifi
sudo util/install.sh -Wlnfv

However, at this point the log script indicates the mn version as 2.2.0d1:

mininet.sumo.traci.rebuildConstants: module references file
creating 'dist/mininet_wifi-2.2.0d1-py2.7.egg' and adding 'build/bdist.linux-x86_64/egg' to it

[ramonfontes]

Yes, it's mininet-wifi. Are you importing Mininet_wifi from wifi.net and using it (net = Mininet_wifi(...))? Please refer sample files at /examples.

[sahilabro]

Thank you.

I was using net = mininet(..) instead of mininet-wifi. I apologise for the inconvenience.

[amigos03]

hi, I am getting git not found error while installing mininet wifi in ubuntu terminal. I am using the commands that are mentioned in github for installation

[ramonfontes]

I suggest you to double check it. There is no problem with the installation steps.

Hi, i'm currently working with propagation models using mininet-wifi, im using the file propagationModel.py as a starting point located at the examples folder, my problem is that whenever i try using the two Ray Ground Popagation Loss Model i get the following error:
AttributeError: 'managed' has no attribute 'bandChannel'
is there a way to fix this ?
i'm working with the pre-configured VM from github by the way:
https://github.com/intrig-unicamp/mininet-wifi
Any help would be truly appreciated, thanks.

[ramonfontes]

Fixed 0c44803

Thank you for the modification, it seems that the error got fixed but now every time I run the script my computer gets stuck completely, the mininet WiFi CLI appears but I can’t write any commands as the computer gets stuck.
I’ve to power it off from the button in order to restart it.
Does that have to do with my particular system?

[CharlieAx10]

Also, the mobility animation doesn’t appear either, the computer gets stuck as soon as I run the script.

[ramonfontes]

I suggest you to take a look at the log files in your system.

[CharlieAx10]

I suggest you to take a look at the log files in your system.

Thank you for the suggestion, i was able to fix the issue. I've a final question regarding the height of the transmitter antenna.
The theory about propagation models says that there's a transmitter antenna and a receiver antenna with a certain distance in between, when calculating path loss on the two ray model i have to use the height of both antennas.
My question would be; ¿What height is mininet-wifi using for the transmitter antenna ?, in this case the transmitter would be the access point i believe.
To calculate path loss im assuming a larger antenna than the receiver antenna since i don't know the real value for the transmitter, maybe i'm missing on something.
Once again, i'd really appreciate any help.

[ramonfontes]

1.0 is the default value: https://github.com/intrig-unicamp/mininet-wifi/blob/master/mn_wifi/link.py#L1083

[CharlieAx10]

1.0 is the default value: https://github.com/intrig-unicamp/mininet-wifi/blob/master/mn_wifi/link.py#L1083

i see, so the only way to change that value is by modifying it on that particular script or is there a particular command for the CLI ?
Thank you.

[ramonfontes]

You can pass antennaHeigh as a node parameter.

Please create a new issue if you have a question about a different topic.

[CharlieAx10]

Thank you, i will.
