SRX

I am running DHCP ip pools on my srx 210 box ..

now i want that my clients (which are linux based boxes) do an automatic ntp sync to an ntp server also connected to  same srx ...

how can i do that ...

You can tell you clients, about ntp service, while assigning ip address through dhcp 

i.e. use dhcp options, however,there are two options you can use, option 4 and option 42 ...

Option-4 (RFC 868 based time servers)

set system services dhcp pool <ip-pool> option 4 array ip-address [ <ip-1> <ip-2> ]

Option-42 (RFC 1769 based NTP servers, suitable for windows environment)

set system services dhcp pool <ip-pool> option 42 array ip-address [ <ip-1> <ip-2> ]

please test it and let me know, one out of two options will work

reards

ok will check it up and let you know 

i have tested it, now time is syncing ... but i did not do any config on linux client boxes. i dont know  how it syncd then 

thanks, guide me more 

by default, linux uses "ntpdate" command to sync its time with ntp servers ...

like,    ntpdate 172.16.16.1

however, users normally make it a cron job to do it manually. But in your case, we told them about ntp service through dhcp options, so your linux boxes might have learned them and do the above synchronization automatically ...

which linux flavour your boxes have, can you share with me ...

regards

i hv chkd the documentation of my embedded linux boxes, it has internal ntp client which can talk to ntp server ....

its is synching automatically when i give dhcp address alongwith dhcp option  

thanks rasmus 

I've seen the commands required for an SRX to get its time from an NTP server. What are the commands to make an SRX an NTP server for others?
