@stormi My bad. Ok I installed the nmap-ncat package under rockylinux and works perfectly now Thank you

My server is up to date

@stormi

Would you like to push a pool-specific public SSH key into the ~/.ssh/authorized_keys file of the specified VM and therefore authorize hosts in the pool to interact with the containers inside the VM?
Answer y/n: 
y
Attempting to push the public xscontainer key to USER@IP.
ID@IP's password: 
Success.
Attempting to refresh the state of the VM
Failure diagnosis: Unable to find ncat inside the VM. Please install ncat. 
Do you wish to retry?
Answer y/n:

@stormi I still have the same problem, the key does not want to install and asks me if I want to try again.

@stormi Thanks, I just tried that and it still doesn't work

@stormi I tried to do it but I don't think I succeeded. Could you send me a more specific doc of what you are doing?

thanks

@stormi OK, thanks. I will try your solution on a small lab.

@olivierlambert yes

@olivierlambert I still have the same problem, even adding the ssh keys before running xscontainer.

@stormi Hi, I just tested and it still doesn't work

@stormi Hello, I don't really see how to solve the ssh problem or even solve the problem with python.

Hello, I tried to install xscontainer but when I run the command to set up my vm I get this response.

Can you help me?
xcp-ng 8.2.1
thanks you

How do I do this?

Hello;
I don't necessarily speak English well.
I tested the slack transport option for the Backups and these work really well.
Only what I would like is that when VMs are created, migrated, stopped and started I can be informed through Mattermost. And having seen the options that web-hook offers (and which would be fine for me to do what I have to do) I was super excited by the plugin.
If you can help me set it up that would be great.
Thank you for your time.

Bonjour,
j'aimerais faire fonctionner le plugin Web-Hooks avec Mattermost mais quand je met test j'obtiens :
