tar 压缩和解压

tar.gz压缩

tar -czvf    my.tar.gz    文件夹名

参数	含义
-c	create：创建一个新的归档文件
-z	gzip：通过 gzip 压缩
-v	verbose：在终端显示打包过程（显示每个文件）
-f	file：指定归档文件名（必须紧跟文件名）

tar.gz解压

tar -xzvf  my.tar.gz

参数	含义
-x	extract：解包归档文件
-z	gzip：通过 gzip 解压缩
-v	verbose：显示解压过程
-f	file：指定归档文件名（必须紧跟文件名）

如果是 .bz2 或 .xz 的文件，则：

• 用 -j 替代 -z （.tar.bz2）

• 用 -J 替代 -z （.tar.xz）

PowerShell 7查询DNS方法

#使用默认DNS服务器查询

Resolve-DnsName jpliuyu.duckdns.org

#指定DNS服务器查询 

Resolve-DnsName jpliuyu.duckdns.org -Server 1.1.1.1

#仅返回IP

Resolve-DnsName jpliuyu.duckdns.org | Select-Object -ExpandProperty IPAddress

# 查询特定记录类型（MX/TXT等）

Resolve-DnsName jpliuyu.duckdns.org -Type MX
Resolve-DnsName jpliuyu.duckdns.org -Type TXT

#测试DNS解析时间（类似dig的查询时间统计）

Measure-Command { Resolve-DnsName jpliuyu.duckdns.org -Server 8.8.8.8 } | Select-Object TotalMilliseconds

Ubuntu24.04 服务器防火墙配置记录

 今天家里的服务器，SSH在日本可以成功访问，

在中国的内网中却访问不了。

查看下防火墙配置

sudo iptables -L -n -v

Chain INPUT (policy ACCEPT 43M packets, 81G bytes)

pkts bytes target prot opt in out source destination

0 0 ACCEPT 6 -- * * 192.168.3.223 0.0.0.0/0 tcp dpt:8888

pkts bytes target prot opt in out source destination

Chain OUTPUT (policy ACCEPT 40M packets, 71G bytes)

pkts bytes target prot opt in out source destination

root@linux:~#

想起来之前配置了防火墙规则，允许CN和JP的IP访问，并且只允许了内网的192.168.3.223一台主机访问。

这下好办了，把192.168.3.0/24整个子网全部允许

sudo iptables -I INPUT -p tcp -s 192.168.3.0/24 --dport 8888 -j ACCEPT

root@linux:~# sudo iptables -L -n -v

Chain OUTPUT (policy ACCEPT 40M packets, 71G bytes)

 pkts bytes target     prot opt in     out     source               destination

root@linux:~#

配置成功，保存配置

sudo netfilter-persistent save

测试，内网的另外一台电脑SSH成功登录。

对了，把以前那条老的规则应该删掉

sudo iptables -D INPUT -p tcp -s 192.168.3.223 --dport 8888 -j ACCEPT

Windows 11 一键切换加密DNS (DoH)

最近经常使用公共热点，比如咖啡厅，麦当劳提供的WIFI，无加密，WEB认证。

认证通过后分配的DNS是传统的53端口明文DNS服务器，所以用着就感觉非常不安全，

虽说https能保证了浏览网站的内容是加密的，但是我访问了哪些网站，通过53端口的DNS请求全部暴露了出去，所以每次WEB认证通过，我都要手动在WIN11的界面上，设置手动DNS，1.1.1.1，并且开启DoH，每次都这样点击设置就感觉手太累了，不如写个小工具，一键切换，每次都能省了不少时间。

直接贴脚本内容吧：

首先Set-DNS.ps1

两个文件放同一个目录，双击Set-DNS.bat,弹出超级管理员请求，点击是赋予权限，

然后输入1，设置1.1.1.1 DNS, 并且开启DoH,禁止回退到UDP53端口,

设置后ipconfig /all 确认

DNS 服务器 . . . . . . . . . . . : 1.1.1.1

DoH: https://cloudflare-dns.com/dns-query{?dns}

1.0.0.1

DoH: https://cloudflare-dns.com/dns-query{?dns}

成功开启了DoH,这样上网就安心多了。

离开公共WIFI后，因为家里网关已经设置了Doh,不再使用Win11的DoH,所以再次运行脚本

这次输入2，恢复DNS为从DHCP自动获取。

Set-DNS.ps1脚本里的接口使用的是[WLAN]

不同的电脑接口的名字不同，可以通过

netsh interface show interface 

查找WIFI 接口名称

查找出来如果不是[WLAN]，就替换[WLAN]为你自己的[接口名称]
