I want to backup server files automatically,so I try to do it with rsync. I use below command to ssh login passwordless.
ssk-keygen
ssh-copy-id [email protected]
ssh-copy-id [email protected]
But when I use rsync, it prompt me to input the passwd.
Note: CentOS Linux release 7.5.1804 (Core)
I am preparing ipv6 of my webserver for ios app. Now I've my server build on a vps that not support ipv6. So I set up a reverse proxy nginx on another server that support ipv6. I want to make the reverse proxy listen on only ipv6, then forward to the server by the tunnel. How to setup the tunnel?
