DNS解析问题

在不同场景下遇到过几次，具体表现：

  1. 不连接有线，只Wifi连接热点
  2. iOA无法加载扫码，网页无法加载
  3. ping www.baidu.com 失败

原因其实是DNS解析失败了，查看这个文件 cat /etc/resolv.conf

# This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
# Do not edit.
# This file might be symlinked as /etc/resolv.conf. If you're looking at
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "resolvectl status" to see details about the uplink DNS servers
# currently in use.
# 
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
nameserver 127.0.0.53 
options edns0 trust-ad
search .

临时修改，添加一个正确的DNS：

nameserver 8.8.8.8

再次重新标准化，就出来一堆DNS,至于这个文件什么时候抽风出错了，没注意到

nameserver 192.168.255.10
nameserver 8.8.8.8
nameserver 10.11.56.23
# Too many DNS servers configured, the following entries may be ignored.
nameserver 10.28.0.21
nameserver 10.28.0.12
nameserver 10.11.56.22
search .

毕竟iOA在Linux上只能说勉强能用。

VSCode代理问题

安装插件报错，但命令行能ping通：

2025-10-20 16:11:15.812 [error] [网络] #2: https://marketplace.visualstudio.com/_apis/public/gallery/vscode/davidfreer/go-to-character-position/latest - error GET Fetch timeout: 10000ms
2025-10-20 16:11:15.813 [error] [网络] #3: https://marketplace.visualstudio.com/_apis/public/gallery/vscode/dbaeumer/vscode-eslint/latest - error GET Fetch timeout: 10000ms
2025-10-20 16:11:15.813 [error] [窗口] Error while getting the latest version for the extension davidfreer.go-to-character-position from https://marketplace.visualstudio.com/_apis/public/gallery/vscode/{publisher}/{name}/latest. Trying the fallback https://www.vscode-unpkg.net/_gallery/{publisher}/{name}/latest Failed

命令行有代理，猜测是VSCode启动时没有从环境读到，需要手动配置：

# id: http.proxy
Http: Proxy
要使用的代理设置。如果未设置，则将从“http_proxy”和“https_proxy”环境变量继承。在 remote development 禁用 Http: Use Local Proxy Configuration 设置时，可在本地设置和远程设置中单独配置此设置。

反正思路就是网络不通就先在Terminal测，如果Terminal能ping通，就大概率是代理问题。

无法访问oa

401 Unauthorized Device
如果您正在PC端访问公司内网，可尝试

刷新当前页面重试
检查iOA登录状态
注销iOA重新登录
如果您正在移动端访问公司内网，可尝试

返回 手机iOA 【重新开启】远程办公
如已经【开启】，请关闭后刷新当前页面重试
以上方式均无法恢复时，请企业微信联系“8000助手”
