Introduction to JUNOS Software
The Factory-DefaultReproductionConfiguration
All platforms running JUNOS Software are shipped with a factory-default configuration. All factory-default configurations allow access using the root account. The root account doesfornot include a password by default. Setting a root password is required before activating any changes to the configuration file.
All factory-de ault c nfigurations also include system logging, which tracks system Noteven s and writes those events to pre-defined log files. The following is an example of
a ypical syslog configuration found within a factory-default configuration:
[edit]
user@host# show system syslog user * {
any emergency;
}
file messages { any any;
authorization info;
}
file interactive-commands { interactive-commands any;
}
We discuss system logging in greater detail in the secondary system configuration chapter.
