Hi Yes, it is possible to gain access via single-user, but single-user mode is for root user to configure something as he likes; but if the machine is accessible for others, you need to edit "/etc/tty" to prompt for a password in single user mode, although keep in mind anyone with physical access to the machine can still retrieve your data through various methods. in /etc/tty note "secure" term which actually has different meaning. It means that you consider, for example "console" as a secure mode; so you have to change it to "insecure". After rebooting and entering single user mode, you will be prompted for a password to get to the shell prompt. On 2012-05-13 17:04, mahdieh salamat wrote: > Hi everybody.
