How do you enable debug mode on a Zimbra server?

To enable debug mode, stop the Zimbra service with 'zmcontrol stop', replace the zmmailboxdmgr script with the unrestricted version, add JVM debug options to mailboxd_java_options using zmlocalconfig, disable the firewall with 'ufw disable', and restart the service. The debug options include -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000. --- **Related reading:** - [Setting up Zimbra Vulnerability Debugging Environment](/news/setting-up-zimbra-vulnerability-debugging-environment) — original article - [Windows Shellcode Study Notes - Extraction and Testing of Shellcode](/news/windows-shellcode-study-notes-extraction-and-testing-of-shellcode) - [Penetration Techniques - Enabling Anonymous Access Shares on Windows Systems via Command Line](/news/penetration-techniques-enabling-anonymous-access-shares-on-windows-systems-via-command-line) - [Penetration Technique: Python Implementation of Exchange PowerShell](/news/penetration-technique-pythonimplementation-of-exchange-powershell)
