Migration
Packing up and moving on, setting up my new workstation – adjusting cables and finding a comfortable posture before starting work
Oh no! The internet connection is up, but I can’t access the usual servers in our group. Switching to Wi-Fi works fine.
Initially, I thought it was a server network segment issue. The new workstation’s wired network wasn’t in the firewall configuration, so I figured an IT colleague could adjust it. However, this network segment hosts multiple servers, and accessing others worked fine, which raised my suspicions. Professional matters should be handled by professionals; eventually, the operations team identified the problem: the server deployed docker
,服务的默认网络__INLINE_CODE_1__和办公室有线网络配置的网段冲突了,导致发过去的数据包,都收不到应答,被路由给了__INLINE_CODE_2__ services.
It’s not unusual for addresses starting with INLINE_CODE_0__服务,也就这台,我比较常用,偶尔用容器部署一些测试服务,没想到还能碰到这个场景。后来细想想,由于整个集团都在一个办公大楼里面,IT部门的同事划分网段,用到了__INLINE_CODE_1 to not be deployed on other servers

# vim /etc/docker/daemon.json
{
"bip":"172.200.0.1/24"
}
Restart the service, switch to a new network, and the server will return to normal access
