Pfsense as an ntp time server



  • Can pfSense act as an Authoratative Time server in a heterogenous comunity of computers since you have/can specify an NTP server?



  • Unless someone packages an ntp server no. The ntp server at system>general is only for syncing the pfSense's own clock. This is especially essential for wraps for example as the wraps don't have a battery to keep the clock running on power outtages.



  • We have a NTP server already in -HEAD but it will not make it into 1.0.

    1.1, most likely.

    Are you using (or will you) openntp there? It just came to my mind, because it has an easily portable version ready and remains clean and slim while doing what it should do. :)



  • Not sure.  Two other people where evaluating OpenNTP and a few other items and going to hack together a soluation for 1.1.

    As far as I am concerned, I would consider it a brilliant idea ;) We just upgraded our OpenBSD machines (the web farm) to 3.8 a month ago and in the run changed from the old ntpd to new openntpd. Small, fast and working as intended - nice one :)
    As it is not that big in size I already thought about using it on some custom openbsd-based cf-card image and would be more than happy also seeing it in pfsense.

    Thanks for the info,
    Grey

    You use it in a high interrupt environment (say 15K interrupts/second)?  I'm curious to see how it performs…ISC's ntpd performs like crap.

    What exactly do you want to know? :)
    As I'm no native speaker, I better ask before interpreting your question the wrong way ;)



  • How does openntpd perform in a high IRQ (interrupt) environment?  A number of my machines on OpenBSD run 15K + interrupts/second - with that load, ISC's ntp daemon sucks ass.
