Unshare

Create a new network namespace, without root privilege.

!!! info ""

Rootless operation requires the kernel to allow unprivileged user namespace creation.

Structure

{
  "network_namespaces": [
    {
      "type": "unshare",
      "tag": "",
      "pid_file": ""
    }
  ]
}

Fields

pid_file

If set, the PID of the process holding the namespace open is written to this path.

The namespace can be entered with nsenter -t <pid> -n when sing-box is run as root, or nsenter -t <pid> -U --preserve-credentials -n otherwise.
