network
The following method allows to change the name of interfaces in ubuntu. The network card below some how is not good recogized by default, one interface is named renameX by default. With this method I assign it the name enp1s0
by configuration.
First I get all mac addesses of my interfaces
ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: rename2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 00:07:43:0c:32:12 brd ff:ff:ff:ff:ff:ff
3: enp130s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 00:07:43:0c:32:13 brd ff:ff:ff:ff:ff:ff
inet 10.7.10.70/24 brd 10.7.10.255 scope global dynamic enp130s0
valid_lft 5639sec preferred_lft 5639sec
inet6 fe80::207:43ff:fe0c:3213/64 scope link
valid_lft forever preferred_lft forever
Then I enable the feature in the grub configuration to set my own interface names.
vim /etc/default/grub
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
Apply the new configuration
grub-mkconfig -o /boot/grub/grub.cfg
update-grub
update-initramfs -u
Configure the new names per mac address
vim /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:07:43:0c:32:12", NAME="enp1s0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:07:43:0c:32:13", NAME="enp2s0"
