What are you using as a time server?

[EckerA]

Hi,
i don't know, it' not mine. but it worked before with "the same settings".
thanks

Hi,

I'm running a few 5400 on K14.41 and sntp is working fine for me.
What do you get on a "sh sntp stat" ?

i guess no solution there..

Maybe the new firmware want NTP instead of SNTP. Have you tried changing that setting?

"timsync timep" instead of "timesync sntp"

[EckerA]

Thanks
that worked..

I have exactly the same problem. I upgraded from 13.68 to 14.41.

We have XNTPD 3.4y on Aix. Seems to be running timep which is a different protocol and it works but I would like to have NTP working.

[Tijl van der Steeg]

Every windows domain controller is an NTP server. Do you have any of those in your network?

[Jarmo Laakso]

That didn't come into my mind.

So i added a windows dc as ntp server with lower priority. Log says:
I 10/13/09 16:27:38 00414 SNTP: all configured servers failed
I 10/13/09 16:27:38 02631 SNTP: server not found at 10.1.31.234.
I 10/13/09 16:27:29 02631 SNTP: server not found at 10.0.16.8.

[Tijl van der Steeg]

Same story: "timsync timep" instead of "timesync sntp"

sntp is old

[Tijl van der Steeg]

Otherwise there could be a problem with a firewall and udp 123. But that's unlikely because nothing changed right?

[Jarmo Laakso]

I updated another switch and sntp stopped working.

So I changed protocol to timep and time is ok now.

So beware that sntp is not working in 14.41. Timep works if there are still timep servers.

I think NTP is a newer protocol which can handle delays in network. Timep is just a service which tells date and time in standard form. Enough for small environments where you have ntp-synced time available somewhere. Anyway timep is enough to keep logs in different systems synchronized.

hi,
at a hp procurve switch roadshow a hp tc told me that this is a bug in the software and that hp knows of it and that it will be fixed in an future release of the software.
it has something to do with the new sntp authentication feature. the switch always send an empty password with the ntp request if authentication is disabled and the server can't handle this and drops the packet.

we started updating to K.14.41 last week and have 23 5406zl's done so far. I just did a sample of 6 and all were working:
sho sntp stat no dropped packets, Tx=Rx

we point sntpv3 to generic linux server.
don't know what else to say
glen
ps: if sntp is old, timep is ancient

Hi,
we have this problem, too. We upgraded a switch to 14.41.
We want to syncronize via sntp from a W2K3 Standard Server with SP2, but the eventlog shows now only errors:
I 01/01/90 01:51:59 00414 SNTP: all configured servers failed
I 01/01/90 01:52:41 02631 SNTP: server not found at 192.168.1.1.

If sntp works fine with Linux, there is probably a error with Windows-Servers.

[Trevor Commulynx]

Got the same problem here. rolled back to 14.34 and works fine.

[Rainer Stenzel TG]

From Procurve support we get an actual firmware K.14.50 and the info, that the problem is solved with firmware K.14.48.

[Case Van Horsen]

In addition to the other suggestions, such as "timesync timep", it also depends the version of software on the time server. I can't get K.14.48 to work with our old Solaris time servers but I K.14.48 (and .41) have always worked when configured with a recent Linux time server.

[Jeff Carrell]

hmm...i've had sntp working on K.14.41 to a cisco 2621 router/timesrvr for a few months...

here is my config:

timesync sntp
sntp unicast
sntp 60
sntp server priority 1 10.222.100.251 3
ip source-interface sntp vlan 100

however, the switch will not sync to a W2K8 server...and i do seem to remember this problem when i upg to K.14.41.....

so, how do we get the latest K.14 code???

cheers...jeff

[Rainer Stenzel TG]

Just open a case via "Support Case Manager" an explain the problem. So I get version K.14.50.

[EckerA]

hi,
i got the info from HP that this bug isn't solved right now, not even with software K.14.51.
But they send me a "workaround", which just disables the massege in the log ;-)

Hi all,
I just got a K14.52 version from HP support. It solves this SNTP issue.
