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
I have some audio files downloaded from Youtube that I want to play in the background, do I know how to do it?
For Linux system administrators, you must understand the ps aux command. If you want to be a Linux system administrator, or you are a Linux user, you should understand this command. ps is process status For short, anyone can find out what kind of program is running on the system and how the status is executed through this command. I saw some programs that should not appear, maybe the system was hacked and used to mine🥹
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.
