Not sure who will use it, but I encountered it myself, because my home is a floating IP.
A software I installed can't detect that the ppp0 network card is an external network, so changing the name can trick him into successfully installing it.
1. File opening
vim /etc/ppp/peers/dsl-provider2. Add ifname eth0 in the last line
plugin rp-pppoe.so
nic-ens3
ifname eth0
Some people may be curious about what to do with this. Let me briefly explain my situation. The super old host cannot install HAProxy or certbo without Docker, only apache and nginx. But I need to automatically apply for and update the certificate on the host, so I let the host mount the folder on another host that can run the certbot program through NFS, so that the verification file generated by him can be directly generated on the old host /home In the /nginx/acme-challenge/.well-known/acme-challenge/ directory, the web page can be successfully verified and the certificate can be obtained. When there are a bunch of vhosts, you can all eat the same folder, instead of creating a directory for each vhost website.
Introduce a bash I wrote to connect to colab vm through ssh. One line of instructions, get colab OpenSSH Server.
On the new version of RHEL 7/CentOS 7 or Fedora, we can check the status and make adjustments through timedatectl.
