Chapter 7: Establishing Basic Connectivity

Root Password

The root user has complete privileges to configure the Services Router, and manage files in the router's file system. Initially, the root password is not defined on the router. To ensure basic security, you must define the root password during initial configuration. If a root password is not defined, you cannot commit configuration settings to take effect on the router.

If you use a plain-text password, the router displays the password as an encrypted string so that users viewing the configuration cannot easily see the password.

The root password must meet the following conditions:

■The password must be at least 6 characters long.

■You can include most character classes in a password (alphabetic, numeric, and special characters), except control characters.

■Valid passwords must contain at least one change of case or character class.

For Common Criteria environments only, the password must be between 10 and 20 characters long and must include at least three of the five character classes (uppercase letters, lowercase letters, punctuation marks, numbers, and other special characters). Control characters are not recommended. For more information, see the Secure Configuration Guide for Common Criteria and JUNOS-FIPS.

Time Zone and System Time

You define the time zone for the location where you plan to operate the Services Router by using a designation that consists of the following information for the location:

■Name of the continent or ocean—For example, America or Atlantic

■Name of the major city or other geographic feature in the time zone—For example, Detroit or Azores

A Network Time Protocol (NTP) server provides accurate time across a network. The router synchronizes the system time with the NTP server, and periodically accesses the NTP server to maintain the correct time.

The time zone and system time must be accurate so that the router schedules events and operations as expected.

For Common Criteria compliance, you must configure NTP to provide accurate timestamps for system log messages. For more information, see the Secure Configuration Guide for Common Criteria and JUNOS-FIPS.

Network Settings

A Domain Name System (DNS) server on the network maintains a database for resolving hostnames and IP addresses. Network devices can query the DNS server by hostnames rather than IP addresses. The router accesses the DNS servers that
