mike@mike-desktop:~$ ifconfig eth0 eth0: error fetching interface information: Device not found
Znalazlem cos takiego:
root@mike-desktop:/home/mike# dmesg | grep eth0 [ 1.974188] r8169 0000:02:00.0 eth0: RTL8168f/8111f at 0xffffc52281bd0000, 60:a4:4c:64:a8:bd, XID 08000800 IRQ 45 [ 1.974189] r8169 0000:02:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko] [ 2.002494] r8169 0000:02:00.0 enp2s0: renamed from eth0
czyli eth0 (LAN interface) teraz nazywa sie enp2s0 ?
Czyli co teraz jest WAN interface?
Skoro mam polaczenie z Internetem to musze miec i WAN interface ?

To nie instalacja qemu/kvm rozwaliła interfejsy tylko zabawy z virt-managerem. Poczytaj o kvm https://wiki.debian.org/KVM zupełnie nie zaszkodzi https://wiki.debian.org/QEMU , https://wiki.debian.org/BridgeNetworkConnections oraz http://wiki.libvirt.org/page/Main_Page
Nowe nazewnictwo interfejsów to skutek działania systemd https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

To nie Systemd tylko zmiana w kernelu.
Jest opcja, która to pozwala wyłączyć, ale w tej chwili nie pamiętam nazwy.
W ogóle nie mam Systemd tylko OpenRC i Eudev, a karta dostaje nazwę eth0, na jaju obecnie 4.9.12, sprawdzone na sterownikach R8169 Realteka i e1000e Intela.

Także nowe nazewnictwo kart nie jest obowiązkowe, chociaż bezpośrednio po zmianie nazewnictwa też musiałem w /etc/udev/rules.d/ to poprawiać, ale przy jakiejś awarii eudeva udało mi się to przypadkowo poprawić na poziomie kernela.

Do parametrów startowych dopisać net.ifnames=0 lub stworzyć własne reguły /etc/udev/rules.d/70-persistent-net.rules
lub 3 opcja poniżej.
I don't like this, how do I disable this?
You basically have three options:
You disable the assignment of fixed names, so that the unpredictable kernel names are used again. For this, simply mask udev's .link file for the default policy: ln -s /dev/null /etc/systemd/network/99-default.link
You create your own manual naming scheme, for example by naming your interfaces "internet0", "dmz0" or "lan0". For that create your own .link files in /etc/systemd/network/, that choose an explicit name or a better naming scheme for one, some, or all of your interfaces. See systemd.link(5) for more information.
You pass the net.ifnames=0 on the kernel command line[/quote]Ostatnio edytowany przez arecki (2017-02-24 19:53:28)

Wszystko pieknie, ale obawiam sie rozwalic system przez niewiedze jeszcze bardziej.
Bardzo prosze, napiszcie dwa slowa jak to zrobic lub podajcie linka do strony z taka wiedza.

Czemu nie użyjesz wyszukiwarki?
Wpisujesz "debian ifnames" i otrzymujesz wyniki prowadzące za rączkę.
Jak się boisz, że coś zepsujesz to zrób kopię systemu.
