Re: [Kea-users] How do I install and configure ISC Kea DHCP Server on RHEL 9.0?

Kea is available for el9 from EPEL (version 2.2.0). -- Sandro I just wanted to clarify that Rocky Linux (and Alma Linux) follow RHEL, not CentOS Stream, so you have 10 years of support. Since RHEL 8, Red Hat offers 5 years of full support and another 5 years of maintenance support [1]. I'm no expert on the difference, but to my understanding only high priority issues will be fixed at Red Hat's discretion during maintenance support. The last minor release of RHEL 8, which marks the end of full support, is scheduled for May 2024 [2]. So, yeah, I was wrong saying RHEL 8 is going EOL in May 2024. But since RHEL 9 is already out, I'd go with that. In the same fashion I will shortly upgrade from Fedora 35 to 37, skipping 36. Since CentOS Stream is a different beast all together, Rocky 9 (or any other RHEL clone version 9) would be my choice when upgrading from CentOS 7. For a fresh install, I'd definitely consider CentOS Stream 9.

Is there a reason for that inconsistency? Daemon filenames are the only case where the dash (character '-') has no meaning at all. In all programming languages including the shell (so a command line) it can get a meaning so be misinterpreted. I'm not quite sure I follow. What can be passed to the `--server` option is defined and checked by keactrl. It's not a leading dash or a dash on its own, either. -- Sandro -- ISC funds the development of this software with paid support subscriptions.

[Kea-users] Where to configure lease length used by kea-dhcp-ddns
Hi, I have setup kea-dhcp4 to hand out IP addresses and kea-dhcp-ddns to update DNS (BIND). That works. But I need to tune the TTL used in the updates. In the log kea-dhcp-ddns tells me: Lease Length: 14000 That's also the TTL value used in the zone update. However, it does not correspond to either `min-valid-lifetime`, `valid-lifetime` nor `max-valid-lifetime` in kea-dhcp4.conf. From the log kea-dhcp4 hands out leases with a lifetime of 42000s, which is what I set in `valid-lifetime`: lease 192.168.101.151 has been allocated for 42000 seconds So, which configuration parameter in either kea-dhcp-ddns.conf or kea-dhcp4.conf do I need to tune to adjust the TTL used in DDNS updates? I searched through the manual, but failed to find a hint. -- Sandro -- ISC funds the development of this software with paid support subscriptions.

Hi, When using keactrl to manage the daemons, the servers are specified with an underscore (dhcp_ddns, ctrl_agent), wheres the corresponding daemons use dashes. Is there a reason for that inconsistency? It leads to interesting "dialogues": # keactrl reload -s dhcp-ddns ERROR/keactrl: invalid server name: dhcp-ddns # keactrl reload -s dhcp_ddns INFO/keactrl: Reloading kea-dhcp-ddns... -- Sandro -- ISC funds the development of this software with paid support subscriptions.
