Red Hat Gives an ARM Up To OpenShift Kubernetes Operations

Slashdot - 13 hours 28 min ago
An anonymous reader quotes a report from VentureBeat: Red Hat is perhaps best known as a Linux operating system vendor, but it is the company's OpenShift platform that represents its fastest growing segment. Today, Red Hat announced the general availability of OpenShift 4.12, bringing a series of new capabilities to the company's hybrid cloud application delivery platform. OpenShift is based on the open source Kubernetes container orchestration system, originally developed by Google, that has been run as the flagship project of the Linux Foundation's Cloud Native Computing Foundation (CNCF) since 2014. [...] With the new release, Red Hat is integrating new capabilities to help improve security and compliance for OpenShift, as well as new deployment options on ARM-based architectures. The OpenShift 4.12 release comes as Red Hat continues to expand its footprint, announcing partnerships with Oracle and SAP this week. The financial importance of OpenShift to Red Hat and its parent company IBM has also been revealed, with IBM reporting in its earnings that OpenShift is a $1 billion business. "Open-source solutions solve major business problems every day, and OpenShift is just another example of how Red Hat brings business and open source together for the benefit of all involved," Mike Barrett, VP of product management at Red Hat, told VentureBeat. "We're very proud of what we have accomplished thus far, but we're not resting at $1B." [...] OpenShift, like many applications developed in the last several decades, originally was built just for the x86 architecture that runs on CPUs from Intel and AMD. That situation is increasingly changing as OpenShift is gaining more support to run on the ARM processor with the OpenShift 4.12 update. Barrett noted that Red Hat OpenShift announced support for the AWS Graviton ARM architecture in 2022. He added that OpenShift 4.12 expands that offering to Microsoft Azure ARM instances. "We find customers with a significant core consumption rate for a singular computational deliverable are gravitating toward ARM first," Barrett said. Overall, Red Hat is looking to expand the footprint of where its technologies are able to run, which also new cloud providers. On Jan. 31, Red Hat announced that for the first time, Red Hat Enterprise Linux (RHEL) would be available as a supported platform on Oracle Cloud Infrastructure (OCI). While RHEL is now coming to OCI, OpenShift isn't -- at least not yet. "Right now, it's just RHEL available on OCI," Mike Evans, vice president, technical business development at Red Hat, told VentureBeat. "We're evaluating what other Red Hat technologies, including OpenShift, may come to Oracle Cloud Infrastructure but this will ultimately be driven by what our joint customers want."

Nautilus search problems on Ubuntu 22.10 - Nautilus does not find files on one hard disk

Linux Questions - 16 hours 44 min ago
Hallo Forum,
maybe anybody could give me a hint how to solve a strange nautilus error:

For some reasons I did a fresh install of Ubuntu 22.10. (was 22.10) on a M.2 harddisk.

The hard disk has seperate partitions for / and /home.

I did copy my old docs to /home (copy paste the documents without any system files)


Everything is working fine... However if search the hard disk for files it keeps searching forever without results.
With a one letter search I still get files. With 2 letters it starts searching without result. There are no errors.

The search works for other hard disks... If I use catfish I get results. Reinstalling nautilus does not help. I have the pdf- compress script add on in Nautilus.

Thanks for any tips to fix.

How to detect and log a DSCP mark ?

Linux Questions - 18 hours 11 min ago
Hi everyone,

I am having trouble detecting and logging a given DSCP mark. I generate DSCP marking on the nodes that generate udp traffic:

'iptables -t mangle -A OUTPUT -s 192.168.4.1 -d 192.168.1.1/30 -j DSCP --set-dscp 46'

This works as expected (checked with tcpdump that the dscp field is correct)

Now the problem, is to detect in an intermediate node, that the incoming packet has the dscp marking equal to e.g., 46.

What I have done is:
- In the intermediate nodes, I have tried setting this (neither works):
iptables -A INPUT -p UDP -m dscp --dscp-class EF -j LOG --log-prefix "received packet with dscp=46"
iptables -A FORWARD -p UDP -m dscp --dscp 46 -j LOG

- I have also added to rsyslog.conf this line -> kern.debug /var/log/iptables.log -> then I restarted the service and now I get some output on that file, but nothing related when it receives packets with that dscp field mark

Thanks for reading!!

A new HPLIP for Slackware

Linux Questions - 19 hours 12 min ago
Hi guys.

For this time HP added support some a new printers:
https://developers.hp.com/hp-linux-i...es?language=fr
but we stuck on hplip 3.20.5 version.

Well, we know that a new releases of hplip require avahi and Pat does not seem inclined to add avahi in Slackware. I agree with this.

So do we have any plans to update of hplip with network printing support in the future for Slackware or not?

Thanks.
