No more NTP for classic macs?

I just fired up a System 7 machine that had the Network Time cdev installed, and was configured to query time.apple.com.  It said time.apple.com no longer supports the version of NTP being used.
It's been a while since I checked, so it's likely this is related to the big ntp vulnerabilities from last December.  The vulnerabilities seemed to be either cryptographic in nature (not really an issue for these old clients) or related to the protocol its self with spoofing and whatnot, which is more a problem for clients than servers.  But I guess they might have stopped providing service to clients using vulnerable versions of the protocol in an effort to "encourage" upgrading.  If it's spoofed though, it wouldn't matter since the spoofing server would obviously return the malicious data rather than ENOTSUP.

I run my own local NTP server, which still supports the older protocols, so I guess I need to change all my older clients to use it since the internet has moved on.

Re: No more NTP for classic macs?

Interesting, because I upgraded my ntp on my local ntp system, and I don't get that error.

I'm actually toying with getting a GPS time source because I'm ridiculous and I don't have anything better to do and who wants to be a stratum 2 when you can be a stratum 1?

Re: No more NTP for classic macs?

Yeah, I've kept my server up to date, but it seems like time.apple.com has disabled some of the older protocol support.  Have you tried with an older client against time.apple.com?  My machines were just configured to use that because it was the default apple one, and has been online for a while.

The GPS time source sounds like a fun project.  The more science-fair-y the better!

I'd have to put one outside of the secured network, since there's no direct routing from the secured internal network to the WAN. I'll try that when I get a chance on the WiFi DMZ.

I do have some FutureBASIC source code for an extension to twiddle the Daylight Savings bit, so it's possible to hack that in.

Re: No more NTP for classic macs?

between you, bbraun, and dougg3, the programming knowledge you have for vintage macs, I dont see why not?

I do know the original NTP control panel allowed you to define the DST parameters. the NTP control panel is one of my staples! it keeps me from having the PRAM batteries installed.
