Hello everyone,
I've just completed a build on an ESXi 6.7 cluster and trying to lock down the security with best practices. I'm finding loads of documentation and videos on the subject, but nothing on the actual commands.
EXAMPLE:
I'm trying to remove unwanted ciphers being used from the install, below is the command and output.
grep -i "^Ciphers" /etc/ssh/sshd_config
Ciphers aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr
What I want to do now is remove unwanted ciphers referencing openssh.com. Like I said I've been searching the internet, but nothing is coming up or it only discusses the subject and not how to do it.
In the attachment I've uploaded I search for grep and nothing returns From the document I take key commands and they don't work in the cli of the ESXi 6.5 or 6.7 host.
What are the standard procedures for making command line changes and updates on ESXi servers? Is there a reference available discussing the proper commands?
