when you have no control over key aspects of your solution, anything can and will happen

the really fun thing is that many users don't even know they are dependant on third parties for their stuff to work correctly.

Funny how some think that running older systems is the issue, when they have no clue as to how the newer systems work and that it doesn't have to be that way.

If there was a good way to notify about the issue and obtain user approval that would be a great start, but not suitable for systems that run headerless.

Even better would be a some kind of automatic management system that auto magically fixed these things.

Re: Old devices

"Just plug it instead to a small 2 port box with the other port instead going to the lan."

so that system that has just 1 port that can be administered via sha1 needs another box in-front of it to proxy sha2.

you could do that or you could put a fw in the logical path blocking all ssh to everything you want & a single bastion host in the subnet of the sha1 system that will only permit sha2 or whatever you want.

Then you use strong auth to get to the bastion host in the required subnet and then sha1 to the old system and any other systems in that subnet that can only use sha1.

you could put the bastion host elsewhere but it ups the risk of the traffic being intercepted from 0 for the solution with the box in front of the sha1 system to a little bit more for something on the same subnet intercepting that traffic (can't happen on a switched network unless a port mirror is configured) to again a bit more if the traffic is routed through a number of systems that could intercept or chnage on route (fw's load balancers, virtual systems, IDS/IPS) etc

the attack risk is much lower on your internal systems than it is if your traffic has to go across a public network even if you use a vpn or private peering in a colo.

Huawei flip flop doesn’t help

If government could make its mind up once and for all telcos like three could get on with 5g.

Is there anything to stop Nokia, Ericsson, Samsung from licensing Huawei tech, commission Huawei to build for them and then sell to phone companies?

Technically not Huawei but realistically it is.

Chinese firms started 5g research way before others did so hold a huge patent portfolio of necessary technologies, I understand politically pressuring China Is the current game but when Huawei etc side step this the west will have egg on their faces.

Why is any of this Vodafones issue

I'm not an Android user, but why has a phone update caused an issue for users on Vodafone? Is the update bespoke for Vodafone, is that still a thing?

DoH

Will chrome tell me I’m using DoH or will it silently work in the background.

What about my local dns filtering, will it bypass my pi-hole in favour of its own DoH, maybe not today but what about in the future if my isp decides to do DoH?

I’ve blocked all port 53 traffic out and in and have a DoH proxy running internally, if chrome decide to silently use DoH in addition to my OS’s DNS I will never know, unless I now also use a proxy and inspect, TLS decrypt - inspect - encrypt, everything. With my tin foil hat I can see how that benefits state actors.

Re: DoH without DNSSEC - no validation ?

Don’t worry just stick with the plain text current incarnation.

Otherwise you check the https certificate of your DoH provider and cheat by pointing your Cloudflare DoH url at a genuine Cloudflare ip so it just looks like you need to x thousand Https requests per day to Your favourite site and zero dns or DoH requests.

Otherwise DNSSEC it is.

This is a live system, Do not Reboot it

~ 2010 i was on the phone with cisco support regarding a 6512r we had recently installed and running in a contact centre. It was up and taking calls but we had some issue iirc to do with ACL's consuming cpu instead of running in the ASIC. sh tech and logs back and forth to Cisco then a lot of webex's. The cisco engineer suggested we up the code to a recent (released after we had issues) version and we planned to install it on the redundant supervisor. at the start of the call i stated the switch was live taking customer revenue generating calls, during our troubleshooting i reiterated the same, before we started the upgrade on the redundant supervisor i repeated the same & that we will do the switch over out of hours, once the upgrade was done i repeated the same & i'd do the switch over over night, she then flipped the supervisors causing both supervisors to boot and all calls to drop & phones to power off (PoE), I was actually on site, a contact centre going quiet is just as eerie as a server room going quiet. Of course i lost the webex when the switch went to. Luckily everything came up ok, still had the original issue despite new code. I sent some really snotty emails to cisco that day!! For some reason i didn't get into trouble for that one!

The issue was too many operands used across the various ACL's causing the cpu to have to process instead of the ASIC's.

The thing about debt is that taxes are paid after costs like debt etc. More debt, less taxes.

Re: In other news....

@Veti

“ The trouble with "correcthorsebatterystaple" is, it doesn't scale. If we all start using "three or four common words strung together", then attackers will start guessing passwords in that format.”

The idea is to increase the number of characters of the password to increase the processing time to brute force it. Doesn’t matter what words are in it, a word attack is a word attack. At least 12 characters With capitals, symbol & number it’ll take long enough to crack to put an attacker off Unless they pay for expensive cracking hardware.

I personally just use the random password which actually looks like it follows a pattern to make input easier. Password is stored and synchronised to my keychain across phone, tablet and laptop.

250 comments largely opposing the change

It’s sad to read the comments and effort people have gone to to oppose the changing of just a few words.

IT is all about change, changing hardware, software, protocols, use cases etc. Somethings don’t change behind the scenes but the presentation is continuously being rejuvenated.

It’s a few words, originally used be a very small number of people and now in more broad use are found not to be in keeping with how the rest of the world wants to use language.

"To use the car analogy here, the fact a car manufacturer recommends that you use a certain brand of engine oil to lubricate the engine, you don't have to use that brand. It is irrelevant how much they spend on R+D every day to develop their engines, the brand of oil you use after YOU have bought the car is entirely your own choice."

Now days you need to ensure the oil adhere's to the specification as determined by the manufacturer, especially in diesels with DPF's and those newer ones with Ad-Blue. DPF's need low ash oils, putting normal oil in will coat the DPF and result in hefty repair bills, especially when the service person will spend ages diagnosing the issue as they won't initially know its just because the wrong oil spec was used.

your conflating this issue with being the fault of the national government, when in fact its the local government who have instigated, bungled & are at fault for this.

In this case local and national governments are from opposing parties, but even if it was the same party its still not an issue from national government when local government have done this against their own citizens without the knowledge or consent of the national government.
