I'm trying to set up a redirection of core-dumps captured on the host into volumes mounted in (dynamically created) containers that are causing the core dumps. I have access to the host PID of the crashing process, as well as access to everything under /proc/<pid> in the initial namespace on the host. How do I identify the container from which the core dump has originated, based on the available information?

I'm trying to create a very basic Smart Inventory in AW24 to subdivide my Alma 8 and 9 hosts using ansible_facts, but I am really struggling to find the correct filter syntax. I have tried all of the following: ansible_facts.ansible_distribution_major_version == 9 ansible_facts.ansible_distribution_major_version:"9" ansible_distribution_major_version:9 ansible_facts.ansible_lsb__major_release:"7" ansible_distribution__major_version:"9" "ansible_distribution_major_version": "9" ansible_facts."ansible_distribution_major_version":"9" ansible_distribution_major_version[]:9 ansible_distribution_major_version[]:"9" ansible_distribution_major_version[]:"9" Whatever I try gives me back an Invalid Query error, the documentation link leads to a 404 and documentation/simple guides seem to be very awkward to track down. -- Actually, from the Automation Controll

I need to monitor Nginx via HTTP response status code (200). Does Nginx have default status code pages either I need to configure stab_status page?

I have a Windows Server that is accessible through SSH, on the server, I went to C:\Users\ftptest' and ran 'git init --bare MyRepo.git On the client, I'm attempting to clone the new repo with git clone ftptest@my-server:MyRepo.git but I get the error: fatal: ''MyRepo.git'' does not appear to be a git repository fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. I'm guessing there's something wrong with my url and git is looking for the repo in the wrong directory, what would be the correct command to clone the repo?

I have a Debian server, on which Wireguard is installed bare-metal. The physical network inteface is called enp5s0. There are multiple services running in Docker containers on this machine, some of which are accessible through a reverse proxy (Caddy) on the machine's public IP address. The machine itself is behind a firewall/router. Is it possible to configure Wireguard and/or the server in such a way that all outgoing traffic is routed through the Wireguard VPN tunnel (which is established to a VPN provider), but each of the already reverse-proxied services remains accessible on the public IP address? If it is, I'll be looking at how to automate the process of changing the VPN server at some interval, so for the brief moment that the connection is being reestablished it would be ideal if all outgoing traffic is temporarily suspended. Could you help me figure this out, please?

I'm trying to understand how we setup an identity provider (idP) in AWS. I can then use that idP from Cognito (using SAML). I'm simplifying the description of my current situation in order to simplify the questions and the conversation. I have one AWS account. We use Google as an external identity provider in that IAM Identity Center (the "External identity provider" identity source). I was able to easily create a new application via a simple, two step process. This is the first screen I get when creating an application in this context: After this, I was able to use this application as an idP for a user pool in Cognito. I have another AWS account. It's configured to use Identity Center (the "Identity Center directory" identity source; the default). When I crea

I had a ~100 GB partition with Arch Linux on it (/dev/nvme0n1p6). I ran out of space, and could not resize it due to adjacent Windows partitions to the right. I created a new partition (500 GB) /dev/nvme0n1p5 using fdisk on a live Arch USB. I mounted it to /. I used dd to copy the data in partition 6 to partition 5, which seemed to work okay. After some debugging with GRUB and fstab, I was able to boot to my lock screen. The first message I get on my lock screen is that the root filesystem is running out of space. GNOME Disk Usage Analyzer (and also df) say that my root filesystem is at 100% capacity. I'm also not able to create new files as a normal user (though I can as root). However, fdisk and the output of mount suggest that /dev/n

I enabled promiscuous mode on a VM NIC to use containers in Solaris and Linux, I'm noticing with this enabled the router VMWare creates has a duplicate IPV6 address of a VM I created. When I invoke the DHCP client on the Linux VM DAD (duplicate address detection) finds a duplicate IPV6 address and network configuration fails. Does anyone know why there is a duplicate MAC address and the solution to this? I'm suspecting its something specific to MacOS. I'm creating two VMs on the same network segment (bridgeX and vmnetX). VM containers use multiple MAC addresses on the same NIC, therefore for one of the solutions to this it's a requirement to enable promiscuous mode for a NIC in the VM server and VM OS, so other VMs can see the VM container's MAC addresses. Yes, I know it's a performance hit. I'm running VMWare Fusion on MacOS Ventura, a network in private host only mode and a DHCP server running in a VM OS container using a VNIC with virtual MAC.

I have configured the setting to keep only the one latest artifact in the Artifact Registry. It does not work. Has anybody else faced the same issue?

=== ADDED TEXT: THIS QUESTION WAS CLOSED BECAUSE IT WAS INCORRECTLY ASSUMED THAT THIS IS NOT FOR A "SERVER ENVIRONMENT": This question pertains to an IMAP server that we are running for multiple external users, not just for myself. This is every bit a "server environment". Users of this IMAP server need to have the kind of email filtering that I am asking about here, and the answer to this question has allowed me to enable this feature. Furthermore, the answer is applicable to any dovecot-based IMAP service in any kind of server environment. === END OF ADDED TEXT I would like to run several dovecot servers on a single linux host, each one listening on port 993, and each one monitoring a separate email address. Is this even possible? If so, would I simply set up each dovecot server with a separate login ID and password? Or perhaps is there another way to accomplish this?
