NTP Server on JunOS (Juniper Operating Sytem)

Several days ago, I have posted about use 'set date ntp' for set date time on JunOS. This intruction is set date time on JunOS, use NTP server and time-zone.

#### Set NTP server and Time-zone

user@JunOS> show configuration | match ntp | display set     
set system ntp server 192.168.2.2

user@JunOS> show configuration | match time | display set    
set system time-zone Asia/Jakarta

#### Verify and failed 'write to localhost failed: No route to host'

user@JunOS> show ntp status 
/usr/bin/ntpq: write to localhost failed: No route to host

user@JunOS> show ntp associations 
/usr/bin/ntpq: write to localhost failed: No route to host

#### Solve it
#### 1. add 127.0.0.1 in lo0 
#### 2. set static localhost to 127.0.0.1 (optional)

[edit]
user@JunOS# show | compare 
[edit system]
+  static-host-mapping {
+      localhost inet 127.0.0.1;
+  }
[edit interfaces]
+   lo0 {
+       unit 0 {
+           family inet {
+               address 127.0.0.1/32;
+           }
+       }
+   }

#### Verify

user@JunOS> show ntp status

 192.168.2.2     .INIT.          16 -    3   64    0    0.000    0.000 4000.00

The last thing, adjust your devices time, make sure it's accurate.
Happy weekend.
