Salve, non capisco l'errore in foto.
Sto tentando di collegare la macchina con wireshark come da guida ma mi restituisce questo errore.

Hi @PaoloLaMuro,

Thanks for opening the discussion. I need further information to help you:

1. What OS are you using?
2. Can you share the network scenario and steps to reproduce the error?

Thanks,
Tommaso

P.S. Please write in English here so that your error can help other people.

thank you for answering.

1.I'm running windows 11 64bit
2. in this scenario there are 2 pc connected with a lan

this is the lab.conf
LAB_DESCRIPTION="A simple example two computers on a single lan"
LAB_VERSION=1.0
LAB_AUTHOR="L. Ariemma"
LAB_EMAIL=[email protected]
LAB_WEB=http://www.kathara.org/

pc1[0]=A
pc1[image]="kathara/base"
pc1[ipv6]="false"

pc2[0]=A
pc2[image]="kathara/base"
pc2[ipv6]="false"

wireshark[bridged]=true
wireshark[port]="3000:3000/tcp"
wireshark[image]="lscr.io/linuxserver/wireshark"

i'm trying at this step to connect a wireshark device with the comand "kathara lconfig -n wireshark --add A"
as in the pic.

p.s. i've copied it wrong here but i've alredy tried without "\tcp" or with "\tcp".

Hi @PaoloLaMuro,

I managed to reproduce the error. Probably you have run the lab, but your containers are stopped (maybe you rebooted your machine?) as in the following image:

To fix the error, you only need to restart the lab and then connect the wireshark device to collision domain A:

kathara lrestart 
kathara lconfig -n wireshark --add A

Let me know if this helps.

Cheers,
Tommaso

Thank you Tommaso but still doesen't working. My containers are fully running. I've tried to restart the lab few times, I've tried with different labs, same problem always.
I've just tried your input to be sure and still doesn't work.

[PaoloLaMuro]

update, at the end i've solved with a clean re-install of docker. Now it seems to work.

Hi @PaoloLaMuro,

I'm glad that you resolved the problem.

Do you know what version of Docker are you using before?

[tcaiazzi]

Hi @PaoloLaMuro,

I found the reason for your error. You can check #256 for more details.

The steps to reproduce the error are the following:

1. Start a machine called X with vstart
2. Start a network scenario Y containing a machine X with lstart
3. Now you have two machines called X running, one in the vlab and one in Y.
4. Run lconfig in Y attaching another CD to X, Kathará will return you the error:

CRITICAL - (KeyError) 'kathara_lollo-fx5lx6ymglgwdoljxihqjw_A'

We will fix the problem soon.

The problem is fixed!
