@lamaz I am going to open a redmine ticket for you as this is missing the key value and redirect the ticket to this page so others can see this.

[JonathanLee]

@lamaz

Yeah!!!

[LamaZ]

Awesome! Warms my heart to see someone else getting value out of these patches and that they are working for others.

@jonathanlee said I am going to open a redmine ticket for you as this is missing the key value and redirect the ticket to this page so others can see this

Let me know how that goes. I tried many moons ago to get it added with no luck. Here is the last time I tried: https://redmine.pfsense.org/issues/8794

I'd follow up myself, but I somehow can't reset my redmine password. I'm guessing too many recent reset password attempts from my IP. The password apparently can't be too complex.

@lamaz that is from 2018 ?? Wow I added some notes in your older ticket just now.

[JonathanLee]

@lamaz thank you for the patches. I appreciate you.

If you wanted the leap second file this is the one I am using

https://www.ietf.org/timezones/data/leap-seconds.list

[LamaZ]

@jonathanlee Has it been that long?! Time flies.

[LamaZ]

@jonathanlee Just added the leap seconds to my setup. Thanks for the tip!

I like that I tried adding my comments to the file and it validated the hash. Put another it gave me an "signature mismatch" because something had changed. I went back and copy/pasted as-is and now have the leap seconds properly setup.

cat /var/log/ntpd.log | grep leap
Mar  3 19:02:51 pfSense ntpd[61552]: leapsecond file ('/var/db/leap-seconds'): signature mismatch
Mar  3 19:03:36 pfSense ntpd[75239]: leapsecond file ('/var/db/leap-seconds'): good hash signature
Mar  3 19:03:36 pfSense ntpd[75239]: leapsecond file ('/var/db/leap-seconds'): loaded, expire=2023-06-28T00:00:00Z last=2017-01-01T00:00:00Z ofs=37

@jonathanlee Off topic, but how do you get Status/NTP to sort like you have shown? 2.6 CE to 22.01 and 23.01 Plus all act weirdly when trying to sort by columns, for me. Thanks.

@jonathanlee said in Authenicated NTP:

@johnpoz you can fax them also I just did, I want to test this, I have seen time jumps during cyber security classes in the past. 10-15 min jumps. Maybe this will fix it again with the use of my firewall I have not seen that in a while. Still I want to check it out. "Users who wish to use this service should send a letter to NIST using the US mail or FAX machine (e-mail is not acceptable)."

@JonathanLee - do they still require a static IP address or can a host name be given instead (in case the IP is dynamic)? Thanks in advance.

[JonathanLee]

@tman222 I was required to provide the IP address provided to me by my ISP.

[JonathanLee]

@deliver I installed the patch that is listed above. LamaZ provided it to us, I am very thankful for it. Use the 23.05 version

[JonathanLee]

@lamaz time flys haha as we talk about time servers

status_ntpd.php.auth.patch

@LamaZ said in Authenicated NTP:

system.inc.ntp-auth.23.01.patch

Folks, just upgraded to 23.05 and these patches still work. Copy them to your /root folder (that's ~ for admin).

cd /etc
patch -u -b /usr/local/www/status_ntpd.php -i /root/status_ntpd.php.auth.patch
patch -u -b inc/system.inc -i /root/system.inc.ntp-auth.23.01.patch

I periodically come back to this thread and remember what I've done over the years :).

I have a PR open that incorporates the patches @LamaZ made (more or less) as well as adds a key ID field to the web GUI. If anyone is interested in testing it out to make sure I didn't miss anything, I can upload equivalent patch files here.
pfsense/pfsense#4658

[JonathanLee]

@MatthewA1 That's amazing can you post the patch, I would like to test it on 23.05.01 "pfSense Plus"?

[MatthewA1]

@JonathanLee Thanks! I tested on a CE 2.7.1 VM as I only have one Plus device, and it's very much a production device. Here are the three patch files. I'm not 100% sure they are compatible with Plus as I have not looked at the PHP source files for 23.09, but I don't believe there is any difference with the modified sections in CE vs Plus.
These are created based on master+9257345. It seemed to work fine with my NTP server, but it would probably be good if someone could test against NIST NTP servers (as I also just setup my GPS based NTP server, so it's possible it was misconfigured but worked anyways)
system.inc.patch
status_ntpd.php.patch
services_ntpd.php.patch

Also, the table on the NTP status page is wider than the title header. I'm not sure there is a way to fix that other than removing one of the columns. If anyone has suggestions, please do share.

[JonathanLee]

@MatthewA1 @LamaZ his was the same way with the column issue see below.

[JonathanLee]

@MatthewA1

All of them show ok under debug thanks for doing this.

I had to remove /src from all the patches or they would not work with plus that was the only issue strip count zero

System works as expected for input area YEAH!!!

Time is showing AUTH under ntpq -c associations

This is great !!

Functions with the status patch also for nist.gov authenticated NTP project.

I had to originally get approved by NIST to even be able to use authenicated NTP with them.

This is an amazing addition to pfSense for time protection from the aging non autheniticated NTP protocol.

[MatthewA1]

Ah I had been using Path Strip Count = 1 when I was testing. It probably makes more sense to just edit the patch file.
Here they are corrected (it won't let me edit the previous post):
system.inc.patch
status_ntpd.php.patch
services_ntpd.php.patch

[JonathanLee]

@MatthewA1 After so many posts in the forum you can edit old posts I think it has been a while for me.
