Predictable Network Interface Names[1], systemd-nspawn(1) NOTES 1. I'm concerned that this might mean As the driver probing is generally not predictable for modern technology this means that as soon as multiple network interfaces are available the assignment of the names "eth0", "eth1" and so on is generally not fixed anymore and it might very well happen that "eth0" on one boot ends up being "eth1" on the next. In "Enable Predictable Network Names?" selecting Yes gives the coded interface names. With predictable device names disabled, we see: While playing with my new Debian 9 on Hetzner cloud I've noticed one strange thing. This feature is called Predictable Network Interface Names and should name each interface in an reproducible way. Otherwise, for any PCI/PCI-X/PCIExpress NIC, a enpXsY style name will be used. Please include an alpha-numeric character in your title (0-9, A-Z, a-z) Compose; Preview; 这个不是系统bug，而是较新的命名规则一致的网络设备命名或consistent network device naming用于取代基于ethx的旧命名规范，老的命名方式有些问题，因为网卡（nics）的命名是基于内核启动时发现设备的顺序而定的。添加新接口可能会导致原来的接口名称改变。 Understanding the Predictable Network Interface Device Names. However, if udevadm test-builtin net_id is ran on the interface, it shows that at least one policy has succeeded in finding a name (slot). === Why? The classic The 2nd problem can be solved by udev rule which pins the interface name to the MAC address of the NIC. While I can certainly see advantage to names like net0, lan0, or wan0, it is eth0 and eth1 that make I thought the advantage of the "new" naming scheme over good old "ethX" was that the device names are predictable. conf files for a specific wireless interface. 0-amd64-netinst.

My question is NOT related if this scheme is better or worse I'm just trying to understand how to use it correcly. When VM is booted I can see, that eth0 interface is renamed to ens3 (I suspect predictable network names mechanism comes into play). The peer network interface can be in a different network namespace. This approach often led to inconsistent naming across reboots, especially with hardware changes. For example, a device named eth2 might become eth1 after you remove a NIC and restart the machine. support for Predictable Network Interface Names. By default, this name takes priority over all other Do you need predictable network interface names? My solution has been to uninstall biosdevname, and that has reliably resulted in always having network interfaces named as eth0, eth1, and so on. ifnames=0 and [if needed] biosdevname=0 to the --append should do what you're asking. ; The names have the following types: I am trying to setup bond configs, based on interface names, but at times, after reboot, the interfaces making up the bond, are being renamed.

UID and FID of the PCI function With enforced UID uniqueness (preferred) Without enforced UID uniqueness; UID: 0x0, FID: 0x0: Eventually I figured out that the modern "predictable interface name" for my Ethernet port had changed, apparently because of the new drives being installed. The scheme provides stable and persistent names based on systemd and The predictable naming scheme provides stable and persistent names to system network interfaces. It is activated by installing the biosdevname package. Use different wpa_supplicant files explains how to configure dhcpcd to use different wpa_supplicant. Share. The one which is connected (eth0) is expected to be consistently There is an option in raspi-config to enable predictable network interface names. Learn how systemd/udev under Linux assigns stable network interface names based on network type, location, and MAC address. Add a comment | 0 Main problem: The interface name is not always the same at boot. , based on the order of detection during system startup. This is possible when there is enough information about the device to generate those attributes and the use of this information is configured. The default is to assign fixed names based on firmware, topology, and location information. I haven't checked the source code and could be totally wrong), is that the kernel name has already changed to the predictable name by the time your RUN commands are executed. just by looking at lspci you can figure out what the interface is going to be called ; Fully stateless Now the problem here is that recent versions of Linux uses a new network interface naming scheme called “Predictable Network Interface Names”. fe0/01 for fast Ethernet port in first slot with a multi port NIC. In this naming scheme, a mainframe network device has an interface name of the following form: <pf><type><bus_id> For example: There's two different schemes available: biosdevname vs predictable network interface name.

Same device name for identical USB sound cards after every reboot. The use case of my ProxMox server is to host Capture The Flag (CTF) images (mainly from vulnhub. The very most predictable interface name is eth0. ifnames=1") and the persistent rules, you still don't get predicatble network interaces. 2. Strangely enough enx+random_numbers related to the MAC are called predictable network names in Linux. This leads to problem, since I need this naming to be deterministic for my network configuration (e. This is a Ubuntu 15. Then it will reboot your raspberry pi. Almost everything is working fine to our needs - yet, I can’t get predictable network interface naming to work.
