Hostname, Time Zone, and Identity Settings

Configure the Hostname

The hostname is the name that identifies the device on the network. A hostname is easier to remember than an IP address.

To configure:

For example:

When you commit the configuration after set system host-name SRX1600, SRX4120, or SRX4300-node1, the system sets the unique hostname as SRX1600, SRX4120, or SRX4300-node1 for the SRX1600, SRX4120, and SRX4300 Firewalls, visible in CLI prompts and logs.

Domain Name and DNS

The SRX1600, SRX4120, and SRX4300 Firewalls support standard Domain Name System (DNS) configurations including proxy, dynamic DNS (DDNS), client, server, relay using DHCP, and advanced features such as DNS snooping and caching.

Configure the domain name and DNS servers on your firewalls at the system hierarchy level. This configuration allows hostname resolution and full identity through DNS.

Configure DNS proxy and resolver under system services hierarchy for name resolution. Use J-Web or CLI to configure the primary and the secondary DNS servers (for example, IPv4 and IPv6 addresses like 8.8.8.8).

For example:

Configure the Time Zone

To synchronize the date and time on your firewall, you can directly set the time zone under the [edit system] hierarchy or use NTP for time synchronization. For more information about how to configure NTP, see NTP Configuration.

• Set the timezone option under system hierarchy.

  Example for UTC:

  Junos OS supports compliance for Year 2000 through 2038, with no time limitations.

• Set the date and time from a configured NTP server in operational mode.

• Set the date and time locally.
