I'm hoping someone here may have some insight to cabling responsibilities under the NBN and also my expected rights under the Customer Service Guarantee (CSG). I was talking to Internode today about transitioning to the NBN and had a few surprises: 1. I will now be responsible for the cabling from my wall socket to some as yet undefined location in the street (sales guy couldn't tell me where that was). 2. I have to waive my rights to the CSG. I have had two occasions in the last year when I've had to call Telstra to come and fix my line issues (which they did at no cost to me). What can I expect under the NBN? -- Tom Robinson 19 Thomas Road Mobile: +61 4 3268 7026 Healesville, VIC 3777 Home: +61 3 5962 4543 Australia GPG Key: 8A4CB7A7 CONFIDENTIALITY: Copyright (C).

swap vs cache

by Russell Coker

# free -m total used free shared buff/cache available Mem: 7962 2212 498 533 5251 4942 Swap: 10719 1732 8986 The above is from my workstation. It's running KDE, Chrome, KTorrent, and not much else. My understanding of the above is that most RAM is being used for cache and it's quite likely that this achieves the goal of reducing the number of storage accesses. The problem is that I don't want to reduce the number of storage accesses, I want to improve the performance of interactive tasks. Ktorrent is configured to only upload 60KB/s so a lack of caching of the torrents shouldn't prevent it from uploading at the maximum speed I permit. When large interactive programs like Chrome and Kmail get paged out it causes annoying delays when I want to perform what should be quick tasks like replying to a single message or viewing a single web page. Any suggestions as to how to optimise for this use case? I already have swap on one of the fastest SSDs I own and don't feel like buying NVMe for this purpose or buying a system with more RAM, so software changes are required. When replying please feel free to diverge from the topic. I think this is an area where most Linux users know less than they would like so randomly educational replies will be appreciated even if they don't help me with this problem. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Kindness and open-source projects

by Andrew Pam

"An open-source community comes about once there is an outside contribution to a project; one-person projects aren't really a community. Once you have that, one question is what the purpose of that community is. Collaborating on the maintenance of the project is clearly part of it, but that needs to be balanced with having some fun. If there is no fun involved, people are likely to leave; if there is too much fun, not much will actually get done and the project will suffer." https://lwn.net/SubscriberLink/758363/9a1f5248b1be96cd/ Note that this also applies to some degree to user groups such as LUV!

Re: Melbourne IT - anyone have any contacts?

Andrew McGlashan via luv-main <luv-main(a)luv.asn.au> wrote .. > > Sorry I can't help, but I wouldn't recommend Melbourne.IT to ANYBODY, We have one domain with them (which my Dad bought in 2000) and there were two other sites under the same account. One of the other domain owners recovered their domain access and changed the notification email to something other than the company inbox. I will be moving the domain in great haste to a viable provider. I am back up now after 8 calls to the same off shore team who told me they couldn't access the account so someone would call me on Monday. NONE of their web recovery tools worked or even recognised my account or domain. Perhaps it would be wrong to can a company on the Internet but: 1) Their social media chat was a bot 2) They can't run any sort of web services 3) They keep you on hold for 15 minutes and then the call drops (automated?) 4) They tell you that they can't do anything then after 7 calls the same coal face employee can achieve a task. Thanks to those of you who replied; and apologies to those who got spammed this message. Cheers P

Melbourne IT - anyone have any contacts?

by piers＠rowan.id.au

Hi there, Does anyone know someone in AU from here? I've got a massive problem because none of their automated stuff works (account recovery, etc) and support can't do anything until Monday. I normally post from another account but it won't work because the expired domain notice was send to an address that was changed and now the lights are out on the DNS. I wouldn't ask if it was important but if you can ping your networks I would be greatly appreciative. If you can't assist then pls forgive this intrusion into your weekend and have a great day! Thanks Piers

DKIM -- sign all emails on a server, responsible for single or multiple domains, not just remote_smtp?

by Andrew McGlashan

Hi, It seems to me that DKIM signing is only normally implemented via remote_smtp transport in exim4 of Debian based GNU/Linux. Let's say you have a mail server, it might be for a single domain or it might be for many domains. How do you get DKIM to sign every single email, regardless of whether or not it needs to transit via smtp to another server? If I send to a different domain (or any that the server is responsible for), but without needing remote_smtp transport, then emails don't get signed. I want to do this as I want to use DMARC and force emails to require both SPF and DKIM signing for every email of any or all domains served by the mail server. There are a couple of edge cases too, but I'm not sure I want to go there. One edge case is when you have a device use SMTP to send an alert via an ISP mail server or other mail server that is not trusted with a copy of the private key. The other edge case being emails sent via PHP (with/without Wordpress for example). I've also played around with using a pipe with "Resent-To" facility, not sure I want to sign these, really, as the original author may b problematic; but if I can sign them, then I would use a special selector for that purpose to help protect reputation. Any thoughts? Implementation help? Thanks and Kind Regards AndrewM

Removing old printer drivers installed as a deb

by Andrew Greig

Hi All, I have had a pretty crappy run with print drivers on my Ubuntu 18.04 desktop, including one that I got from Epson in England. But today, after accepting the offer to upgrade, my machine jumped from 16.04 to 17.10. But before I could enjoy it it offered the upgrade to 18.04, same as my desktop. But the Printer driver I had installed in 16.04 is now running extremely well in 18.04, same printer, no surprise. So now, I want to remove all traces of the other epson drivers I had installed from deb files. How do I find them, how do I delete them? I will use exactly the same driver as is running so well in my laptop. Can someone point me in the right direction, in RPM land I was fine. But there is better maintenance of GIMP and Darktable in this side of the force. Gratefully Andrew Greig

Recording from HDMI, is it possible?

by Mark Trickett

Hello All, >From what I have read and the like, HDMI is supposed to be a "secure" connection that does not allow recording. My experience so far bears this out. I have a Viewer Assist Satellite Television system, the satellite dish, the LNB, and the set top box. That said box is a UEC device, actually a custom Linux box with an infrared remote control for the choice of channel and the like. It has the outputs for component signal to the TV, and HDMI. I used to use it with an old style tube TV, to good effect, but it is now connected to a reasonable LED TV that has the option to record to USB, but will not do so for HDMI input. Is there any way to subvert that, with a PC in the middle, is it even possible to put a HDMI signal into a PC, or is the PC out to a monitor only? Regards, Mark Trickett

cooperative learning about FOSS via IRC

by Russell Coker

I think it would be good to try cooperative learning online in the evenings and possibly weekends. The idea is that everyone would join an IRC channel at a suitable time with virtual machine software configured and try out new FOSS software at the same time and exchange ideas about it via IRC. It would be fairly informal and people could come and go as they wish, the session would probably go from something like 6PM to midnight and anyone could just take a break for dinner etc whenever they feel like it. I've got some under-utilised KVM servers that I could use to provide test VMs for network software. The general idea would be for two broad categories of sessions, ones where an expert provides a training session (assigning tasks to students and providing suggestions when they get stuck) and ones where the coordinator has no particular expertise and everyone just learns together (like "let's all download a random BSD unix and see how it compares to Linux"). As this would be IRC based there would be no impediment for people from other regions being involved (hi Rick) apart from the fact that it might start at 1AM their time (sorry Rick). Rick, if you want to run a session then 9AM on a Saturday or Sunday would be a reasonable start time for people here that might be OK for you. While the aims of this would mostly be things that relate to LUV (IE Linux and *BSD) I would be happy to coordinate a session on ReactOS as well. I'm thinking of running training sessions on etbemon, DNS, Postfix, BTRFS, ZFS (maybe with Craig), and SE Linux. I'm thinking of coordinating learning sessions about DragonflyBSD (particularly HAMMER2), ReactOS, Haiku, and Ceph. If people are interested in DragonflyBSD then we should do that one first as in a week or so I'll probably have learned what I want to learn and moved on (but not become enough of an expert to run a training session). I'm also interested in volunteers to run training sessions or coordinate learning sessions. There are some skilled members of this list who never turn up to meetings, hopefully some of them will be interested. Note that the topic doesn't have to be something that interests me, all we need is a trainer/coordinater and a group of people who want to learn. So the issues to be discussed are: 1) What communication method to use? IRC? What server? 2) What time/date for the first session? 3) What topic for the first session? DragonflyBSD? 4) Do we try and make this a mostly-LUV thing or just open it to the world? I wouldn't block random people who want to join, but I also wouldn't necessarily advertise it where people who aren't LUV members would see it. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
