DIGITAL HOARDING: UBUNTU MIRROR

Filed under
Ubuntu
HowTos

I have a bunch of Ubuntu machines on my local network at home. They all periodically need to check for updates then download & install them. Rather than have them all reach out to the official mirrors externally to my network, I decided to run my own mirror internally. This post is just a set of notes for anyone else who might be looking to do something similar.

I also do a lot of software building, and re-building, which pulls all kinds of random libraries, compilers and other packages from the archive. Having it local saves me repeatedly downloading from the ‘net while the kids are on Netflix School Zoom classes.

Don’t do this if you’re on a super slow connection because the mirror will probably never finish building. Also probably don’t do it if you have a per-byte billing arrangement with your provider. This will chew quite a bit of bandwidth, especially the first run. But even subsequent runs can do too, depending on how much chrurn in the Ubuntu Archive there’s been since it was last executed.

  • Kafka destination improved with template support in syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    The C implementation of the Kafka destination in syslog-ng has been improved in version 3.30. Support for templates in topic names was added as a result of a Google Summer of Code (GSoC) project. The advantage of the new template support feature is that you no longer have to use a static topic name. For example, you can include the name of your host or the application sending the log in the topic name. From this blog you can learn about a minimal Kafka setup, configuring syslog-ng and testing syslog-ng with Kafka.

I’m going through a short technical course about Vue (JavaScript framework), so this must have put me into the right mindset.

  • Partners Feel ‘Betrayed,’ ‘Taken Aback’ By Microsoft’s Direct Calls To Customers

    A California MSP learned a lesson years ago when a software vendor tried to go direct with his end users. So when Microsoft demanded contact information for his customers, he gave them an email address that went directly to him instead. Earlier this week that email account, which was set up about 18 months ago in the hopes that it would not be used, received a message from a Microsoft business development specialist offering his customer “free training.” “That’s exactly what I would do if I was trying to steal someone else’s business,” said the MSP, who asked not to be named because he fears retribution from Microsoft for speaking out. “It’s just wrong. It’s just wrong. Plain and simple.”

  • Windows 10 bug corrupts your hard drive on seeing this file's icon

    In August 2020, October 2020, and finally this week, infosec researcher Jonas L drew attention to an NTFS vulnerability impacting Windows 10 that has not been fixed. When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records. The researcher told BleepingComputer that the flaw became exploitable starting around Windows 10 build 1803, the Windows 10 April 2018 Update, and continues to work in the latest version. What's worse is, the vulnerability can be triggered by standard and low privileged user accounts on Windows 10 systems.

  • Open source software security in an ICT context – benefits, risks, and safeguards

    In a recent report, contributors to free and open source software (FOSS) claimed they spent only 2.27 percent of their contribution time on security. In our latest blog post, we delve into open source software security, and discuss why it’s key for building robust and open interoperable networks. [...] Is open source software better than proprietary software when it comes to security vulnerabilities? Elias Levy, the person behind the infamous (vulnerability) full disclosure mailing list, Bugtraq, said two decades ago: “No. Open Source Software certainly does have the potential to be more secure than its closed source counterpart. But make no mistake, simply being open source is no guarantee of security”. Building and delivering complex system software without security vulnerabilities requires investment and due diligence, regardless if the code is open sourced or proprietary (see figure 1, below). As the Mozilla Foundation states: “Security is a process. To have substantial and lasting benefit, we need to invest in education, best practices, and a host of other areas”. Tools and resources are available. With safeguards in place, OSS can be used effectively at low risk to realize its intended benefits. ICT products relying on OSS must be developed using methodologies and safeguards that ensure the expected level of security is met. OSS can accelerate innovation, reduce the development timeline, speed time to market, realize cost savings, and be secure. ICT vendors must take responsibility and practice a higher level of due diligence when using OSS components.

  • Email is the messenger you should migrate to

    But the most important thing: Delta Chat allows you to communicate even with people who don’t use Delta Chat at all, all you need is an email address! If you write to someone without Delta Chat, they will just get a normal email. I would argue that even beats Matrix or XMPP.

    Conclusion: If you are concerned about security when chatting and would rather use a decentralized messenger (no silo), you are in good hands with email and Delta Chat.

  • IMAPS specialisations – call for participation in the public review of LIMAPS, OIMAPS, SIMAPS and TIMAPS!

    The objective of this public consultation is to produce updated releases of the IMAPS specialisations, which will provide insights on specific interoperability viewpoints of the digital public service, i.e. the legal, organisational, technical and semantic interoperability viewpoints. Both IMAPS and its specialisations assess the various areas of a digital public service in terms of behavioural interoperability specifications, capabilities and manifestations. The update of the releases of the IMAPS specialisations will be based on change requests coming from stakeholders interested in the solutions.

  • Looking into Linux user logins with lslogins

    One convenient way to list details about user logins on a Linux system is to use the lslogins command. You'll get a very useful and nicely formatted display that includes quite a few important details. On my system and likely most others, user accounts will start with UID 1000. To list just these accounts rather than include all of the service accounts like daemon, mail and syslog, add the -u option as shown in the example below.
