[stork-users] Stork dhcp6 internal server error: number overflow

Tue Jul 23 18:05:26 UTC 2024

Thank you the clue. This makes Stork work as expected now.
Many thanks to you and the others for making and supporting Stork.

For any others using Ubuntu, the included native Ubuntu 24.04LTS packages via apt do not currently support anything newer than kea-2.4.

I uninstalled the Ubuntu kea packages and then installed the ISC package repository as noted in this document: https://cloudsmith.io/~isc/repos/kea-2-6/setup/#formats-deb
I just only used the setup.db.sh file noted in the first recommended section.
Then I installed the ISC version of the packages, which have the additional package name prefix of 'isc-' to differentiate from the native packages.

Example:

sudo apt remove kea-admin kea-common kea-ctrl-agent kea-dhcp-ddns-server kea-dhcp4-server kea-dhcp6-server kea-doc
sudo apt autoremove
sudo apt install isc-kea

Then edit your kea config files as normal.

Thanks again!!

You'll need to update also your Kea to 2.6

After having done this, I see there were commits merged in that apparently have resolved this issue a month ago.
I am still having the same kind of error reported in Stork.

Example:
processing Kea command by daemon [6] dhcp6 on machine [2] 216.17.94.7 failed
internal server error: unable to parse server's answer to the forwarded message: Number overflow: 18446744073709486065 in :0:210

processing Kea command by daemon [6] dhcp6 on machine [2] 216.17.94.7 succeeded

The Stork message cycle is the same as before for me: succeed, fail, succeed, fail, etc

Kea server:
Ubuntu 24.04
kea-dhcp6-server/noble,now 2.4.1-3build3
isc-stork-agent/noble,now 1.17.0.240610135320

Stork Server:
Ubuntu 24.04
isc-stork-server/noble,now 1.17.0.240610135325

Am I experiencing a different issue or is the same issue still existing in my current versions?

You might want to add a note indicating you alo reproduced the issue. The more people are affected, the better the visibility IMHO.

I will wait patiently for the next release to see if it fixes the bug.

Thanks again for these great tools that ISC produces!!

It is a known bug - please search the list of issues against Stork.

I just recently upgraded my stork server and dhcp server to Ubuntu 24.04 LTS.
I also refreshed the stork server app and the stork agent apps to the latest via ISC apt repo.

DHCP Server ( Kea - 2.4.1)
Package: isc-stork-agent
Version: 1.16.0.240405082622

Stork Server
Package: isc-stork-server
Version: 1.16.0.240405082626

The stork server is showing this in the web event logs
 2024-05-14 11:59:16
 processing Kea command by daemon [6] dhcp6 on machine [2] 216.17.94.7 failed
 internal server error: unable to parse server's answer to the forwarded message: Number overflow: 18446744073709486065 in :0:210

After about 15-20 seconds I get this
 2024-05-14 11:59:36
 processing Kea command by daemon [6] dhcp6 on machine [2] 216.17.94.7 succeeded

This just repeats every minute. The error and overflow number are identical every time.
There is only 1 DHCP server talking to the Stork server.

I haven't been using these servers for a while before the upgrade so I am not sure if it was behaving this way before the upgrade or if this is new behavior since the upgrade.
I tried full server reboots of both DHCP and Stork server machines.
If I push the "Get Latest State" button in Stork for the Kea machine, it successfully completes.
I tried removing and re-authorizing the Kea machine in the Stork server.

Is this a config issue?
Stork bug?
Ubuntu issue (it's the newest LTS release)
How best should I troubleshoot further?

Thank you!
Justin
