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
Introduce a bash I wrote to connect to colab vm through ssh. One line of instructions, get colab OpenSSH Server.
My mainframe basically has remote logs set up, and all of them are sent to the log center on the Synology NAS. Among them, there is a Raspberry Pi that is used as a router, and there will be a bunch of sshd verification attempts to log in. Basically, I only allow public key verification, so I don’t want to use passwords to brute force it, but a bunch of logs of verification failures are really good. Hate.
This function is very useful, but be very careful, read it first and then delete it, if you make a wrong directory, you will die miserably
