✅ Have you read and understood the above guidelines?

Yes

📜 What is the name of the script you are using?

Proxmox VE LXC IP-Tag

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/tools/pve/add-iptag.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

No response

📝 Provide a clear and concise description of the issue.

I used this script on all my Proxmox VE hosts when it was released: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/tools/pve/add-lxc-iptag.sh)"

Everything always worked fine.

I saw that a new script had just been released, allowing you to update a previous installation.
This new script correctly detects the previous installation.
It correctly asks if you want to proceed with the update.
The script ends with a message saying it's ok.
But since then, when creating an LXC, or when changing the IP address of an existing LXC, the automatic addition or modification of the IP tag no longer occurs.
In /opt/iptag, there is an iptag file.
This file does indeed contain the configuration mentioned in the script. But on the site, you're talking about an iptag.conf configuration file!
The iptag.service file in /lib/systemd/system/ contains the line ExecStart=/opt/iptag/iptag.

I did, of course, restart the service (systemctl restart iptag.service), but nothing worked.
I didn't restart the PVE hosts because I can't right now.

PS: The source code link (https://community-scripts.github.io/ProxmoxVE/scripts?id=add-iptag) returns a "404: Not Found".

THANK YOU.

🔄 Steps to reproduce the issue.

Open the Proxmox VE shell, paste and run the script: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/tools/pve/add-iptag.sh)"

❌ Paste the full error output (if available).

No error message!

I rebooted a Proxmox VE host, but nothing changed. The problem persists. I'm sending you some logs from the Proxmox VE host.
We can see that IP-TAG correctly finds the number of LXCs and VMs, and that it forces the IP addresses to be updated, but nothing works.

@MickLesk, @anyblabla There's still an incorrect link to the script on the website. As for the fact that tags are not given, it happens when the config is not updated.

Use the command:
cat /opt/iptag/iptag.conf
and:
ls /opt/iptag

Also, if your internal IP differs from the specified mask in the config, then you also need to change it in the config.

CIDR_LIST is responsible for this function.

Re.
Exactly, I don't have an iptag.conf file!
I only have one iptag file.
That's what I was saying in my first message.
And when I used the old script, I never had to create a configuration file manually.
So, I understand now.
Okay, I created iptag.conf with what works for me.
Thanks for wasting your time :)
Sorry for my bad English :)

On the other hand, I just used the script to install iptag, so no upgrade since it's not installed yet, and everything works fine. The iptag.conf file is created correctly.
