NethServer Version: 7.5.1804 (final)
Module: network
Hello,
i’ve inserted modem in NethServer, and on network tab i see this:
how i can configure these grayed enterfaces?
is there any “best-practicies”?
what i want - is to setup failover. Modem will have higher priority than wired.
also:
[root@nethvo network-scripts]# ifconfig enp0s29f2u1
enp0s29f2u1: error fetching interface information: Device not found
[root@nethvo network-scripts]# ifconfig eth0
eth0: error fetching interface information: Device not found
i created /etc/sysconfig/network-scripts/ifcfg-enp0s29f2u1
with:
DEVICE=enp0s29f2u1
BOOTPROTO=DHCP
and it doesn’t help.
on windows system it creates network interface with dhcp client and gets ip 10.0.0.10
ok. i have some progress.
after removing cdrom: eject -t cdrom
i get new network interface enp0s29f2u2, and i can configure it.
but i still cant use it.

Why? what is blocking?
Who is 10.0.0.2? It’s blocking you.
10.0.0.2 it is nethserver
oh… sorry… made mistake on last copy&paste…
