Hi team, I just want to open the maximum number of ports (More than 100 ports) on a Linux VM. I'm trying to install each service and getting an error. Can you please tell me the location of shell scripts to install the service and open the ports on my machine. Below are some ports I'm targeting.

Hello, guys! How are you? I'm facing a problem. I have 2 networks (192.168.1.0/24 and 192.168.2.0/24) and what happen is this: in the 1st network (192.168.1.0/24) there's a gateway (192.168.1.1) to the Internet, and the 2nd network needs to pass through the 1st network to reach Internet. To connect both networks, I have 2 servers (Debian "Stretch" 9.6.0) working as MASTER and SLAVE, and the idea is to use them as gateway for the 2nd network, like this: [INTERNET] --- [1st GATEWAY] --- [192.168.1.0/24] --- [2nd GATEWAY (Servers MASTER/SLAVE: Debian)] --- [192.168.2.0/24] Both servers are using ..read more

First of all, happy new year. Unfortunately, since the last upgrade of LMDE 5 Elsie Debian 11.2 bullseye Version, the sound output does not work properly. Sometimes, it does, but stops than when opening the application again. For the Intel Tiger Lake-LP Smart Sound Audio the driver is sof-audio-pci. I have audio sound via my bluetooth headset but for example not via my default internal speakers or headphones. It is really strange. It happened just very recently after the last upgrade. If you have any advice, how to proceed, I really would appreciate it. Whit best regards and thank you in advan ..read more

I am running Debian Aptosid on MSI motherboard A75MA-G55 series with AMD A8-3870 APU and Radeon HD 6550D graphics card. I can boot normally with kernel 4.10x. However, with recent upgrades, the kernel 4.11x fails to boot unless I give "acpi=off" in the boot command. With acpi=off, I cannot suspend the machine. Can anyone explain why the kernel 4.11x need acpi=off, and how can I boot without it ..read more

Hi all, I'm trying to deploy Debian workloads on K8s clusters. There was no issue so far, but recently after rollout on one staging env we faced OutOfMemoryError issue for an application. I have tried comparing the ulimit values with Amazon Linux2 and configured the same on my Debian AMI but not able to resolve this issue. Please find the error message from the application below: 2022-12-19 07:23:42 java.lang.OutOfMemoryError: unable to create new native thread 2022-12-19 07:23:42,713 WARN [Timer-Driven Process Thread-19] o.a.n.controller.tasks.ConnectableTask Administratively Yielding FieldMa ..read more

Hello. I'm on Ubuntu 22.04 and I'm trying to extract all the files from a (bootable) Debian ISO,add some new files and then re-generate a bootable ISO image. I'm trying to accomplish this task using Cubic and without a graphical interface,but only giving the most appropriate commands on the terminal. Below you can see what I tried to do and the commands that I've issued. In both cases,for some unknown reasons,the preseed.cfg file that I have added does not stick. Can someone help me to understand why ? thanks. 1) Using Cubic. I've copied and pasted this preseed.cfg file : d-i debian-installer ..read more

Good Day everybody! I need to create an absolut minimal distro with the following: nginx server bluetooth and wifi communication basic file operations I plan to build this with the yocto project. The board must run a webserver for the local network, should be able to connect to the internet via Wi-Fi and should be able to communicate with bluetooth (e.g. file transfer). The disto should be also able to write files to the board. Is it possible/realistic to create a distro with only kernel, the application mentioned above and their corresponding dependencies? How do I find out which dependenci ..read more

Hi LF Team, I'm currently not sure to include this in which category but below is my issue I had scheduled a CKAD exam on 11-July-2022 12:00 PM and the exams have been migrated to PSI bridge. The PSI bridge never installs on the Linux platform even-though the system checks on Linux foundation portal says your system checks pass, System checks on the PSI portal also states that your checks have passed. When I download and click the PSI browser nothing happens on the Linux. The candidate handbook does not mention how to sort this issue and also I wasted 2 hours on the examination day had a terri ..read more
