Maybe, It is not widely known that ESXi dcui command.
dcui is Direct Console User Interface.
We can use dcui command in ssh.
1. ssh Login
2. dcui command execute.
3. Amazing,It is the same as physical Screen.
4. We can modifing settings for ESXi.
I intorduce VMware KB 2039638.
Accessing Direct Console User Interface (DCUI) from an SSH session (2039638) | VMware KB
dcui command is under the sbin directory.
[root@localhost:/bin] ls | grep -i dcui
[root@localhost:/bin] less dcui
"dcui" may be a binary file. See it anyway?
