These instructions assume 2 ESXi servers: ESXi0 & ESXi1
Both of these servers have a datastore named Admin for Administrative stuff and a Folder named Utilities for storing useful things.
ESXi to ESXi
The following 2 sections are basically lists of Copy-Pasta commands for each server.
ESXi0
mkdir /vmfs/volumes/Admin/Utilities/sslmkdir /vmfs/volumes/Admin/Utilities/ssl/ESXi1mkdir /vmfs/volumes/Admin/Utilities/ssl/ESXi1/keysmkdir /.sshcd /.ssh/usr/lib/vmware/openssh/bin/ssh-keygen -t rsa -b 4096lscat id_rsa.pub | ssh root@ESXi1 'cat >> /etc/ssh/keys-root/authorized_keys'cd /etc/ssh/keys-root/ls -lcp /.ssh/* /vmfs/volumes/Admin/Utilities/ssl/ESXi1/keys
vi /etc/ssh/sshd_config- (Ensure the following items are in the file)
PermitRootLogin yes UsePAM yes # only use PAM challenge-response (keyboard-interactive) PasswordAuthentication no
/etc/init.d/SSH restart
ESXi1
mkdir /vmfs/volumes/Admin/Utilities/sslmkdir /vmfs/volumes/Admin/Utilities/ssl/ESXi0mkdir /vmfs/volumes/Admin/Utilities/ssl/ESXi0/keysmkdir /.sshcd /.ssh/usr/lib/vmware/openssh/bin/ssh-keygen -t rsa -b 4096lscat id_rsa.pub | ssh root@ESXi0 'cat >> /etc/ssh/keys-root/authorized_keys'cd /etc/ssh/keys-root/ls -lcp /.ssh/* /vmfs/volumes/Admin/Utilities/ssl/ESXi0/keysvi /etc/ssh/sshd_config- (Ensure the following items are in the file)
PermitRootLogin yes UsePAM yes # only use PAM challenge-response (keyboard-interactive) PasswordAuthentication no
/etc/init.d/SSH restart
At this point, you should be able to SSH from one to the other without needing to enter a password.
