« on: February 27, 2024, 02:16:34 pm »

hi,
i had an ha proxy stopped with this log
<13>1 2024-02-24T11:24:40+01:00  kernel - - [meta sequenceId="1"] <6>pid 99645 (haproxy), jid 0, uid 80: exited on signal 11

i also found a bunch of these messages (in configd)

i found nothing relevant in the ha proxy log

any idea where i could get more information?

thanks

24.1 Legacy Series / Re: KEA Control Agent issues

« on: February 05, 2024, 03:33:47 pm »

hi

tbh i didn't read kea original documentation, i just tried to make it work.

imo hostname and control agent shouldn't sync

now i am back to isc older version after i found the leases page completely empty

I'll probably gonna give another try in the 24.7 or 25.1 version

...
use localhost in control agent address

use same port with ip of the interface in HA

Thank you for putting time into this. Although I don't think it will work that way. The Config Template  from the KEA documentation show the below pictures (and it does make sense; binding the control agent to localhost host, the other node can't communicate with him/her/it).

Does it work for you?

```
 +-host-1-+       +-host-2-+
 |        |       |        |
 |   CA <===\   /===> CA   |    ===== - HTTP connection
 |   #    |  \ /  |   #    |
 |   #    |   X   |   #    |    ##### - UNIX socket
 |   #    |  / \      #    |
 | DHCPv4 ==/   \== DHCPv4 |
 |        |       |        |
 +--------+       +--------+
```

Edit: You are right, I read that the other node doesn't need the CA to communicate, it's only for the us humans. But assume I want to use the RESTapi to control the KEA node, I want to bind it to non-localhost. And in that case the issue becomes ... well, an issue

I was hoping someone would confirm this use case and in the next step I'd (or he/she/they) would open a bug report.

24.1 Legacy Series / Re: KEA Control Agent issues

after a lot of test and guessing i think i got the right message:

HA_LOCAL_DHCP_ENABLE local DHCP service is enabled while the OPNAGO1 is in the HOT-STANDBY state

use localhost in control agent address

use same port with ip of the interface in HA

leave empty This server name in "high availability"

hope it helps
