# ubuntu 更改網口名稱

# (於 192.168.32.128 測試)

#

# 參考網頁 : https://caloskao.org/ubuntu-nic-rename/

#

#######################

#====================

# 1.查詢網路介面名稱

user@arkime01:~$ ip link

#--------------------------------------------------------------------------------------------------------------

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000

    link/ether 00:0c:29:c9:af:f6 brd ff:ff:ff:ff:ff:ff

    altname enp2s1

#================================================================================

#2. 新增規則檔案 : /etc/udev/rules.d/70-persistent-net-generator.rules

#  我們可以藉由 Linux udev 將網路卡名稱更改成自己喜歡的名稱

#

#  a) 首先，使用 sudo nano /etc/udev/rules.d/70-persistent-net-generator.rules 指令建立一個規則檔案，

#     將新名稱與網路卡 MAC 位址寫入 (MAC 在前面的 ip link 指令有列出 )

#

user@arkime01:~$ sudo nano /etc/udev/rules.d/70-persistent-net-generator.rules

## 格式: SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="網路卡MAC位址", NAME="網路卡新名稱" 

#---------------------------------------------------------------------------------

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:0c:29:c9:af:f6", NAME="eth0"

#---------------------------------------------------------------------------------

#======================================================

# 3. 編輯設定檔 /etc/netplan/00-installer-config.yaml

#

user@arkime01:~$ sudo nano /etc/netplan/00-installer-config.yaml

## 原檔案內容 , 須修改網口名稱

#---------------------------------------------------

# This is the network config written by 'subiquity'

network:

  ethernets:

    ens33:

      dhcp4: true

  version: 2

  

  

## 更改後內容

#---------------------------------------------------

# This is the network config written by 'subiquity'

network:

  ethernets:

    eth0:

      dhcp4: true

  version: 2
