I setup both machine A and B with same OS version. Then setup the same docker images and container. In the container setup the ssh trust. But, I found if in A ssh to B works. The reverse can not work. On the B machine, if I call following command still require password.
ssh localhost hostname
I have tried check every steps. But can not figure out what's the problem.
- Rocky Linux 8.8
- openssh-8.0p1-19.el8_8.x86_64
- openssh-server-8.0p1-19.el8_8.x86_64
ssh -vvv from B to B shows
