I'm definitely new to Linux. Build a Linux Ubuntu vm in Azure for syslog purposes. Microsoft security configuration recommend /etc/passwd- file permissions should be set to 0600. As soon as I did that, the vm will not be able to boot successfully. It fails to start the networking services. Is this normal? Any help is greatly appreciated.

Thanks Kit
