[memo] 設定 Ubuntu 固定 IP/ How to Configure Static IP Address on Ubuntu Server/Desktop

by

手動改 : sudo ifconfig eth0 192.168.0.1 netmask 255.255.255.0

在 /etc/netplan/00-installer-config.yaml
用 DHCP 取 IP

# more 00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
    enp0s3:
      dhcp4: true
  version: 2

增加 /etc/netplan/01-netcfg.yaml

network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      addresses:
        - 192.168.100.33/24
      gateway4: 192.168.100.1
      nameservers:
        addresses: [8.8.8.8, 1.1.1.1]

需 rm /etc/netplan/00-installer-config.yaml
免得跟原來的config衝突,
再執行

sudo netplan apply

 

OVH:

Some sample …

for office lan

network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: no
      addresses:
        - 192.168.1.11/24
      gateway4: 192.168.1.1
      nameservers:
        addresses: [8.8.8.8, 1.1.1.1]

use sshfs to mount remote filesystem , command sample

by

安裝 command :
apt-get install sshfs

sshfs [user@]host:[remote_directory] mountpoint [options]

sshfs -p 2200 [email protected]:/home/rimmon DEV

fusermount -u DEV

sshfs -p 2200 -o reconnect [email protected]:/mnt/tslog_bak ~/TSLOG_BAK

fusermount -u ~/TSLOG_BAK

速度測試

sshfs -p 2200 -o reconnect [email protected]:/mnt/tslog_bak ~/TSLOG_BAK
