The next deep magic Linux program to change the world? Io_uring

gerdesj Silver badge

Re: Io-uring is not new news

I have a pair of switches on the bench at work. They cost about £10,000 each. They have 28 x 10Gb ports and two 100Gb links each. They boot a rather strange Debian for the control plane and the good Lord knows what does the data shifting plane is running - they are running Dell OS10.

There is a good chance that io_uring and co will blur the old style control/data plane on network hardware and we will get really converged thingies where the switch, router and server (and data) are properly one thing.

Not yet, despite the bollocks from "hyper converged".

Re: OpenWrt or DD-WRT?

I would take the job on if asked and I would point out that it will take at least a day and at my rate that is quite a lot of lolly.

On the other hand, you can have one of these nice four port APU4 based boxes running pfSense, that I can have up and running inside two hours. I keep a stock of them and will have your config backed up and to hand and can replace it within a drive plus 30 mins, if it fails.

If you want a CARP (VRRP) clustered jobbie and have a suitable WAN, I can do that too - all for less than trying to wedge a new OS on your ancient hardware.

"Thanks" to the pandemic I have a black belt in VPNs, routing, RADIUS, VoIP and all the other paraphernalia of remote working. At one point during the pandemic, I had the WAN at Kingston Comms emulated in my dining room (IPv4 and 6) so I could set up a customer system from Hull - a pair of Fortinets with thirty odd VLANs on the inside, rather a lot of IPSEC tunnels and a lot of port forwards. I have consumer grade Netgears at home so I couldn't use a CLI to magic loads of VLANs etc, so a lot of clicking ensued. I even used IPv6 NPT, some fancy footwork and a couple of tiny VMs on my home ESXi to emulate their external facing web gear. Obviously, I whipped up a DNS server with split horizon to emulate the internal and external facing experience. I might have gone a bit far at times but whilst everyone else was learning how to bake soda bread, I was doing my job 8) I also colour coded all the Forti firewall rules and the NAT related stuff (it's a right old palava on a Forti). It looked sodding complicated, yet logical by the time I finished it.

It took me two weeks to setup and test. I shipped them oop North (I'm in Somerset) with an excruciatingly detailed set of wiring instructions and photos and spreadsheets, and they fitted them and cracked on.

That's how professionals operate, in my opinion. You don't take the piss out of the customer - you cost up their request and offer an alternative that might work better and be more cost effective

Microsoft extends Teams into VMware and Citrix VDI

"For the hard of thinking- to save you posting an irrelevant reply such as 'use Linux'"

Well you can fuck right off: my job title is Managing Director and I use Linux. I actually have less problems than my Windows sporting staff and colleagues, with Teams. No it isn't for everyone. Why would you want all your software to update in one go instead of hunting around on disparate web sites? Bloody nonsense and it takes a few minutes instead of sometimes hours. I do an awful lot of Windows updates from a SBS 2007 (nope!) to the latest and greatest. It's a monthly chore for all of us across many, many systems, some of which need careful handling.

I too get paid for my time and I have Evolution to connect to Exchange and LO for office work. I used to teach IT so please don't tell me it can't cut it in the office space. Do you know what a hanging indent or a decimal tab stop is? ... and I can be similarly disparaging with respect to spreadsheet stuff and databases and DTP, all of which LO manages fine and also has a rather odd LOGO built in, which is charming. MSO is franky a bit crap. The ribbon really is a pain. I get the idea but it really slows you down finding functions and it is really hard to explain over the phone when doing support.

I use Arch (actually) and Teams ...

I managed to batter the Teams preview into submission about 18-24 months ago thanks to Pipewire and recently a rather nifty noise cancellation plugin - https://github.com/werman/noise-suppression-for-voice#pipewire

Now, I'm looking forward to a progressive web app thingie instead of an Electron thingie. Presumably because MS have had minimal traction with PWA and have decided that Linux users can be relied on to beta test stuff for them properly and not bleat on social.ms and get told to run sfc /scannow!

Yay - progress!

Microsoft changes the way it certifies network cards for Windows Server

gerdesj Silver badge

A network card is a packet shifter. Yes there are some very funky new ones that are basically full on computers.

This smacks of wankery: "nice NIC you have there, shame if we don't rate it (lol)"

Funky NICs generally should not have anything fancier than an iSCSI initiator built in that you avoid anyway because a decent userspace implementation closer to the upper levels of the stack work better anyway. NICs that do Ethernet frame checksums or even encroach a little further up the stack to say the TCP level can add value.

"Microsoft’s own Storage Spaces Direct" - imagine if acceleration for this nonsense starts to get built into your NIC. That's a monopoly bingo call.

Re: Sharing documents

Perhaps but you are too close to the coal face.

Many moons ago I insisted that my company had quite an involved document structure and style hierarchy. I used to teach DTP (int al) Our ISO9001 Quality Manual was quite a beast and still is. I have used Arch Linux n LO for over a decade (OK I used to use Gentoo).

Yes there are bugs in all software but LO is starting to come together quite nicely.

All the wankery about LO lacking something is quite literally that - wankery. Calc has a decent function set and is extensible. Writer does the job too and so does Base and the rest of the suite - I regularly query my work financials via JDBC for example.

MSO is basically all about getting you on a sub and seemed to have forgotten about innovation.

"and there is no real Open Source replacement for Outlook"

We've been using Evolution EWS (you can use more than just EWS) for many years now and you get full interoperability with Outlook apart from the crashes/freezes. It also lacks a ribbon which suits me.

I think Evo looks a lot nicer too but that is subjective. It is much faster than Outlook on the same hardware.

I own a MS Partner but insist on Arch (BTW) on my own gear, so I think I have a decent sized foot in both camps.

Kernel + initramfs is about 20Mb which is basically enough to boot Linux on any amd64 box, with all the drivers needed included, along with an initial RAM based filesystem and some utilities. Another 5Mb for Intel microcode so my NIC and wifi etc get early initialization.

If you add /lib/modules/ then that's less than 200Mb and that is all the rest of the drivers ... for everything that is supported - filesystems, devices, several varieties of firewalling etc.

Re: My favourite thing

"stored there to be on an "Internet" site"

From memory all that internet stuff is done by using another NTFS stream and storing a flag file in one that you won't see in Explorer, which can only see the default stream. You might be able to stop Windows and hence PS from seeing that stream by deleting the extra stuff.

You'll need to do some research on this. If nothing else you'll find out where viruses like to hide out or perhaps you can find a use for streams yourself. Shadow copies are probably stored in them too - can't be arsed to check. My console prompt is $ or # on my gear.

Arrogant, subtle, entitled: 'Toxic' open source GitHub discussions examined

gerdesj Silver badge

Re: Eh?

I once whined about something and some bloke called Ben Greer threw me some code for dot1Q VLAN support he was adding to Linux and said "give this a go". I also whined on the Samba mailing list about something, got some help and a few days later I had made a monster:

I ended up with an elderly Compaq server with Redhat or Mandrake (can't remember) with 10 VLANs and 20 nmbds per VLAN! samba and the kernel were hand compiled. The point of all this was a multi VLAN network with lots of Windows NT and Windows 3.11 WG machines but without a domain - all in quite randomly named workgroups. I now had a unified browse list. Novell shop. South West England. 2000ish

You do get wankers in all walks of life and you don't need to be working on a FOSS project to experience wankery. I have been that wanker myself too at times (I'm sure). The example about Linux kernel dev being toxic is well trod and Mr T famously has calmed down. Try reading LWN comments for a real rundown on how it's now done, although I do note an increasingly Hacker News flavour to the comments until someone like Neil B turns up and pulls the conversation back to reality.

This paper smells of sponsored research vs FOSS. It is a divisive result about a divisive subject - follow the money.

Re: Excellent

You laugh but I remember a Finance Director using Lotus 1-2-3 for "word processing" back in the '90s.

I also remember the Company Secretary (her actual job title, UK ltd company and she was not a Director but a secretary - not confusing at all)! I (all of IT) wired her up to our nascent network (me and some CAT4 etc and a couple of hubs) and migrated her to Win 3.1 and taught her how this mouse thing works. Next day she had it on the floor next to the old dictation pedal and she used her foot to control the bloody thing! Seriously clever podal-dexterity. She could touch type and move the mouse with her foot. However her knowledge of WordPerfect keybindings was legendary (CTRL-F9: Font) and using MS Word held her up so I got the DOS WP working and kept her seriously productive.

How to find NPM dependencies vulnerable to account hijacking

Re: "an opportunity to preempt this threat"

Sooo 2000s (and yes I did have test servers back in the day)

Nowadays you have snapshots for your VMs and backups that can be restored quickly and replicas of your VMs. You rarely have to go back to tape these days.

Yesterday I restored my home PBX because (salient facts):

* I'm an IT bod - obvs we have a home PBX

* Wife does dog boarding at home

* We have electric underfloor heating, a fairly open floor plan and 75% of ground floor is laminate. U/F is connected to its own consumer unit (UK) with ten zones

* IT gear is mostly in the attic - VMware esxi (Dell T420) and router and switch and other stuff

* IT gear in the attic is powered off one of the U/F circuits with a UPS

* ... leaky dog ... ... very leaky dog ...

I have yet to 100% confirm that a dog killed one room's underfloor heating but it is rather likely. I've got five out of ten zones switched off via the consumer unit and one of the switched off zones is where they pissed. Whilst working out what the hell was happening I flicked power off and on a few times.

The Dell VM host decided that its battery backed cache on the RAID had lost data. I'm not sure exactly why because I monitor all my gear and my customers with Icinga1 and 2 (migration ongoing) and none of the logs indicated a problem. Power went out, UPS depleted and box crashed. Outage was about 12 hours but the battery on RAID should have managed several days at least.

I had three MariaDBs on that box and two went wibble. I recovered my PBX from backup (Veeam), my Nextcloud was fine and Zoneminder needed a parameter to ignore knackered data in INNODB and I also had to delete the redo logs (which I thought should have saved me - nope) and I was able to dump the zm databases to files. I recreated my ZM db and dumped the data back in.

Backups are quite handy,

Microsoft sounds the alarm on – wait for it – a Linux botnet

gerdesj Silver badge

Re: knock, knock.

I am a fan of f2b but it cannot deal with massive botnets. That said, it does deal with a lot of the usual suspects because they don't bother with massively distributed IPs because the majority of their targets don't have f2b or anything like it.

f2b is pretty lightweight and keeps the majority of the yobs out. After that you need some funkier stuff.

Botnets rely on speed for initial connect so a few seconds delay can cause them to move on or you can be cruel by allowing an initial connect and slowing everything else down. TCP is a three way handshake: SYN, SYN/ACK and LOL. If every mail system popped a three second delay into the SYN/ACK and the final ACK (not LOL really - I'm a fucking comedian) then spam would be abated by roughly the Plank Constant.

I basically don't bother with f2b these days but that might change. I do enforce TLS 1.2 or better for my POs. IMAP with TLS and SMTP with STARTTLS and reasonably good passwords.

Security is all about evaluating what is happening now. I think I'll be putting f2b back in again quite soon.

I'll just pick at one thread: As you say big finance need low latency and what you don't mention but probably assume - confidentiality. That is of course why they shouldn't put a box in between A and B that inspects traffic. A and B will share a hardware stored secret of some sort and have custom hardware that can encrypt and decrypt messages at something like nano second or better latency. It has to be better than LAN latency, how better is a matter of engineering and requirement but the latency for network connections over megametres are the big win. Even so: a general purpose firewall, no matter how fancy will not cut it.
