We are setting up a captive portal for guest users using our Cisco ISE servers, and we have a linux box running BIND just for those users. All other OSes besides apple work fine and redirect to the ISE guest login page to allow users to sign up for guest access, but Apple does not. Cisco has said we need to redirect captive.apple.com back to the ISE server to get the portal splash screen, but I can't get BIND to recognise an apple.com configuration file in the named directory. Any ideas how this might be able to be done?

I cant ping my Kubernetes Service from an external machine. Internally, from Proxmox host it works.

First, let's share some context. I have been tasked to design a new development environment for the team I work in. Most details of the constraints don't matter for this question, though. After a bit of research, I have come to the conclusion that the best base would be an immutable Linux distribution. In my case, Fedora Kionite. From my understanding, the whole root FS is built as a set of image, the base image is provided by fedora, and we can add more layers if we ever need to touch the root FS. I would like to preinstall some tools and software into the system and I have three options : Automate the entire installation through scripts. Connect as the user (with a default password before they touch the computer) and install all tools for their users. Do the installation in a layer and then ship this layer to all of the systems. The two first solutions are ways that I understand and know I can build. The last

Faced a problem while trying to setup port forwarding on ubuntu 24.04 - turns out, any NAT rules in iptables (PREROUTING, in particular) are completely ignored.

I have 3 computers with a combined total of 10 6TB Hard Drives, all WDC WD60EZAZ-00SF3B0. The other hard drives in the computers are not having issues. For these 10 drives, the short tests run fine, but extended tests get stuck at 10%: Self-test execution status: ( 241) Self-test routine in progress... 10% of test remaining. The extended self test routine recommended polling time varies from drive to drive from ~200 minutes (~3.5 hours) to ~750 minutes (~12.5 hours). I have had the tests run for about 3 days with no change in status, so I presume the tests are stuck. I have cancelled the extended tests and rerun them multiple times to no avail. I am fairly confident that the drives are healthy since they pass the short offline test and I would not expect all 10 drives to be failing at the same time. I'm not sure if this is a problem with the manufacturer or my configuration. It seems there might be

Can one use Azure API Management (APIM) to set a hard spend limit (an absolute dollar-value cap that stops traffic once reached) for an Azure Cognitive Services resource?

I'm unable to receive any emails on my email server at jessiekirk.xyz. I setup Postfix and Dovecot on my Raspberry Pi 4 (Ubuntu). I followed along with the tutorial at samhobbs.co.uk, deviating on Dovecot setup as its been updated since the tutorial was written. I was able to receive emails by SMTP and SMTPS, send via SMTPS and check via IMAPS (using FairEmail). Next, following instructions on EasyDMARC, I set up DMARC, SPF and DKIM (via OpenDKIM). I also added an MX record and added email aliases to comply with RFC2142. I'm now not able to receive emails, though I can still send them. Things I've tried to fix it: Checked

I came recently accross one bug which after 3 day venture I have not figured out yet. I run mysql on a Ubuntu 24.04 LTS base server. The process crashed and rebooted whole system due to insufficient memory. It happened already in the past many times. It just reboots and then it runs again. However this time the server has crashed and since then it became unpingable. I contancted my provider and they have told me I have issue in GRUB. I went to rescue mode, mounted all disks and started inspecting. I reinstalled GRUB, upgraded etc. but none of it worked. After struggling I reinstalled kernel and the server became pingable. Even ssh worked. After that I have rebooted the server and I tried ssh into it. But I got "connection refused error". I inspected the ssh, firewall, iptables... All seemed ok. Server was up, network was up, just the port 22 was closed. After another reboot, the server went unpingable. After struggling for day I gave up and installed l

I am looking for a way to temporarily disable or stop an Azure Cognitive Services resource to ensure no further requests are processed and to halt consumption-based billing. How can one disable/pause an Azure Cognitive Services resource to prevent further billing on that resource?

¿Cómo optimizar la configuración de memoria RAM y uso de swap en un equipo de producción que ejecuta un servidor web Apache y una instancia de MySQL? Actualmente tiene 16 GB de RAM, pero se observan picos de uso que causan lentitud en las operaciones, y quiero evitar que el sistema use excesivamente el swap.
