Issue Description

Attempting to take over the Octopus-001 machine (192.168.10.5, Debian 13 / OpenSSH 10.0p2) via SSH, but the root password z4bB$Zz4b authentication keeps failing.

Troubleshooting Done

Server authentication methods: publickey, password
root + password: ❌ Authentication failed
Multiple common usernames (admin/octopus/debian/ubuntu/user/test): ❌ All failed
Local public key (zcode-clone) not authorized
Multiple failures once triggered a temporary ban (Not allowed at this time, automatically lifted after about 40 seconds, suspected fail2ban)

Request

Please do one of the following on the Octopus-001 local console:

Option A (recommended): Add public key
`` bash mkdir -p /root/.ssh && chmod 700 /root/.ssh echo "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIGiCLAo10kZ6olctmQqRyZqUNl0dntriJUs4fKGLzyCK zcode-clone" >> /root/.ssh/authorized_keys chmod 600 /root/.ssh/authorized_keys `

Option B: Reset password
`` bash passwd root # Note case sensitivity and the $special character `
