you’re welcome.

what i’ld suggest… a general rule that i like to always follow is to use a test system for everything new. but that does not need to be a full separate system every time.

lets say you have your mailbox and want to try getting new mails from it using fetchmail. first you can use uidl mechanisms to only fefch every mail once and besides that leave them all on the server, but i like it a bit more secure: create a second email adress/account at your mail providers service only for testing. thus you can do whatever you like to to test the mechanisms only without even touching your real inbox (maybe even fill it up with large emails and look how the system reacts, i once had an email account with a cheap provider that deadlocked the inboxes when full…). then when everything is as you want it, switch the account and password (or create another config file for fetchmail) and your’re done. every change (not only fetchmail things) could go tested this way before going live with the changes. filtering could be done with procmail for example, but when the mda that is called by procmail somehow exits with success when the email really isn’t delivered, then the email might get lost forever depending on the settings of course. so fiddling with new stuff always carries the risk of not fiddling correctly ;-)

have fun !

Its possible to tell your mta (like postfix) to use another mta for all mails, or only some domains etc, so using a third party to play the internet facing service then getting the mails by fetchmail, storing them in a dovecot server is easy. on the sending part you could use your standard email client (i.e. thunderbird on pc or k9-mail on smartphone) to send it to your postfix instance that also sits on the server hosting your dovecot service. the mta there takes the mail and delivers it by rules which could just be using the mta of your freemailer using username/password of your account for all outgoing emails. i am doing this but the “external” mail system are my servers as well, i just don’t want emails to stay too long on VMs in the datacenter where i have no access to the physical disks in case something goes wrong.

a raspberry pi is sufficient for such a aetup (i am using a pi4 currently but for emails only i’ld say a 3 or older would do too), adding a disk via usb makes storage huge and cheap then, i use two usb ssd’s in a raid1 for storage… that server could be only accessible through vpn if you whish, depending on your skills and needs (i mainly use ssl client certificates that are supported by k9mail and thunderbird so it fits seamless to be connected through a haproxy that authenticates these before proxying the plain connection to the pi) clients like thunderbird can offline-store all emails (configure download-or-not per imap folder) making searches easy and quick while my k9 client can search locally or on the server if needed.

maybe adjust maximum mail size of your own mta to exactly match (or slightly less) that of the freemailer you use to prevent surprises of big but later then unsent emails.

its possible to have a nextcloud instance on that same pi that acts as an email web mailer just in case of (i really dont need it, but i’ve set this up anyway). nextcloud is also great for syncing/backup files pictures, contacts notes todo lists and calendar of your phone (where i use davx5 opentasks and foldersync for). there are other webmailers available but installing /using nextcloud is not a too bad idea either ;-)

i suggest also setting up some automatic offsite backup with snapshots of that pi then to cover emails and the setup and its configs ;-)

one example of a program that did multiple things is sfdisk, it used to make the kernel reload the new partition table but that was not its main job, only changing them. the extra functionality moved to blockdev which is nearer to doing such as it also triggers flushing buffers and i think setting read/write status. i am fully ok with that change as it removes code from a program that doesn’t need it to another that already does similar things so that other partitioning programs like gdisk fdisk or parted could go the same way so that maintainers of the reread-partition-table things can concentrate on one solution at one place (in userspace) instead of opening issues at an unknown number of projects that also alter partitioning. the “do one thing” paradigma is good for developers who maintain the code and i pretty much appreciate their work. if you are up to only want one-day-flies that either die or take huge amounts of resources only for keeping them alive (image of a mayfly in an emergency room and a heart-lung machine attached while chirurgs rushing around trying to enlenghten its life a few seconds more) then you are good with monolithic tools that could hardly be maintained and suck allday as no one wants to fix any bugs or cannot without creating new ones due to the tightened dependency hell it has internally.

the point is not a lack of examples doing wrong but where one wants to be heading towards.

Lol what???

wouldn’t that be the definition of stable?

the computer on voyager 2 is running for 47 years now, they might have rebooted some parts meanwhile but overall its a long time now, and if the program is free of bugs the time that program can run only depends on the durability of the hardware, protection from cosmic rays (which were afaik the problems the voyager probes faced mostly, not bugs) which could be quite long if protected from hazardous environments and maybe using optoelectronics but the point is that a bug free software can run forever only depending on hardware durability and energy supply, in any other way no humans are needed for a veery long time ;-)

However, systemd makes the system much more secure and reliable as it is

less secure and less reliable day-by-day you meant? systemd introduces needless dependencies ever since as if that was it sole intention ever from its very beginning, which already were used for wide attacks, and exactly those attacks that the people working hard to remove unneeded dependencies for security reasons meant to prevent by things like “do one thing only” (but security was not the number 1 reason for this one i think), systemd instead: ‘lets add another level of that exponential dependency tree from the insecurity hell’ felt like they did this stupid thing intentionally every month for a decade or more.

and stability… if you don’t monitor what systemd does, you’ll never know how bad it actually is. i’ve made custom scripts to monitor systemd’s failures (failing in doing a very primitive of its job) and there are hundreds (actually varying around 200 to 300 sometimes more) of such per day on all our systems for one particular(!) measurement only that was breaking service stability and i wrote a measure-and-fix+monitor workaround. other fixes were not monitored however, only silently fixed by workarounds, thus just unnumbered systemd bugs/instabilities in the dark that stole a lot of work capacity…

if you run distros with systemd, unreliability is your daily experience unless you don’t really care or have never experienced stability before - like running a service (a single process) for 8 years without any interruption then it suddenly stops and you go like “was it maybe an attack? the process died, how could that be? were there any connects from outside at that moment?” not talking about not updating something that long, but “stability” itself CAN be like if you dont stop it, it’ll still run in 10000+ years maybe millions, more likely that humans extincted themselves way earlier than of a process “just dying” by a bug… while systemd even randomly stops things that were running well for no reason (varying) once a month more or less (also varying in what it actually randomly stops, sometimes (2 times) it even stopped ssh on my servers, me asking myself if i should create yet another workaround for systemds buggyness to not locking me out again from network or ratjer go for the real solution for most* of all systemd problems - *see below) on the few standard installs i personally have as i didn’t have the way to automatically replace provider installed distro on VMs in the DC. i want this replacing automatically for the same reason why i don’t like systemd, it causes manual work for a thing that should go automated. however due to systemd’s perpetuated instability i now managed to have this way, and every second working on getting rid of systemd is worth it 100k times. this however does not solve all systemd-introduced problems as the xz attack showed (a systemd-dependency on xz made the infected xz library beeing useful-for-the-atracker during compiletime of sshd binary with which then the attacker could infect the newly built sshd binary),one could still be attacked through systemd’s dependency hell even if one does not use systemd by oneself, but the build machines used for your distro could be affected/infected by systemd’s needless dependencies when “also” compiling for systemd-affected distributions thus there is the risk of becoming a victim of needless-systemd-dependencies while not using systemd at all. however the attack through systemd dependency (and that the public solution was not the removal of needless dependencies only included as source for superflous third party “needs”) made clear that systemd is an overall problem for security that will not be solved quickly but stay just like all windows insecurities will stay as long as they whish to push them to their “users”.

systemd reducing overall security and its unreliability combined with some builtin impediments (i.e. when debugging its defects) is what drove me away from systemd. there are solutions way more stable and way more secure (and way better documented btw) that do not call in for needless dependencies, reducing risks, attack vectors and increases overall debuggability i.e. by deterministic behaviour as an easy example. and none of its important (to me) promises have been fulfilled yet by systemd, drop-in-replacement? have heared that lie thousands of times, but in the last decade i have not experienced it a single time in a distro and it does not seem to be included/finished any more.

for windows users or windows admins a linux with systemd on it IS an improvement in stability, security and of course for updating, yes. but all of that does not come from systemd, rather the opposite is the case, systemd reduces it month by month, thats my experience and thats the most important experience for me, idc what lies whitdepapers tell or what broken promises are believed by anyone or the masses, i want secure and stable servers and services and systemd does not fit in for any of these goals and the time it was still “young” and early problems could be accepted in the hope they get fixed soon are gone, but without those fixes having ever appeared.

What’s the alternative to ads, though? Not everyone wants to (or can afford to) pay for every site they use.

its not about paying for the site a user uses, its about paying those who run the site (and less to pay for someone only “managing” the site by doing actually nothing)

maybe these could be alternatives:

• patreon
• flattr
• micropayment in general
• donations (somafm runs on donations)
• link to shopping platforms (musicians on somafm mostly have links to the songs on amazon that you see while playing the song for free)
• communities, like FSF, local groups
• some small payed supporter part (like lwn.net) while the important stuff that makes the win-win of the site is free to use
• maybe the list from this page can help too: https://kinsta.com/de/blog/patreon-alternativen/ Kickstarter Indiegogo Podia Sellfy Buy Me a Coffee Memberful Hypage Ko-fi Substack Kajabi Gumroad WooCommerce Mighty Networks MemberPress Uscreen

maybe even a combination of multiple of those *whoa!!! mindblow!!! could be a good choice to allow usersvto choose how to contribute.

so really only choosing to offer exactly one option that also puts all users at a real risk of real attacks where they can get ripped off of all or lots of their real money and data for the sake if earning 0.003 ¢ per each putting them at high risk is not really what should be done, or do you personally profit from their users high risk and are thus completely okay with it? hope not.

if you have to earn money with your project or whatever, why not offer several options to choose from? why only one? and while we’re at it, offering an ad-free “membership” for 400 times the price of what they would earn by the same visitor with ads like they try here sometimes, does not make any platform look good, but the opposite.

there are many platforms that i would pay for monthly and i would spend much more money alltogether than now on that if their price would not be artificially pushed into astronomically heights per service…

there is one project where i do donate each month a little bit via recurring bank transfer since years. my transfer says the name of the project and “donation” thats pretty easy to setup for both sides, but too complicated for those who pay designers money so they can place the ad layers on top of the 400 other layers of spypixels and navigation controls… really ? lol*

if those you are talking about cannot afford to have a bank account for some reason, i guess they also cannot receive the revenue of ads on their webpages ;+)

saying there are no alternatives to ads is rather a candidate for the lamest excuse award ;-)

its not just ads and malware, and its not only about beeing sorry for them. ads are also manipulating how people think. not only the obvious things like “that product is good”, but also that products in general would help (with problems you didn’t have). and the format itself of ads (even without considering its contents) already has a changing effects on the minds of those who watch it. i am thinking of some parts of neil postmans thoughts about television back then and i guess there is plenty of possibilities to make a realistic conspiracy theory out of it why exactly the most poisonous parts of television are replicated to the internet with massive force even though everyone ignores ads in the net. i like theories

unfortunately, feeling sorry for them does not help society to stability. 😥

you should definitely know what type of authentication you use (my opinion) !! the agent can hold the key forever, so if you are just not asked again when connecting once more, thats what the agent is for. however its only in ram, so stopping the process or rebooting ends that of course. if you didn’t reboot meanwhile maybe try unload all keys from it (ssh-add -D, ssh-add -L) and see what the next login is like.

btw: i use ControlMaster /ControlPath (with timeouts) to even reduce the number of passwordless logins and speed things up when running scripts or things like ansible, monitoring via ssh etc. then everything goes through the already open channel and no authentication is needed for the second thing any more, it gets really fast then.

isn’t a security feature. At most it can be a safety feature.

o,O

not the home screem

if had to use windows at home i’ld screem too.

not too surprised they didn’t change that.

The whole point of ssh-agent is to remember your passphrase.

replace passphrase with private key and you’re very correct.

passphrases used to login to servers using PasswordAuthentication are not stored in the agent. i might be wrong with technical details on how the private key is actually stored in RAM by the agent, but in the context of ssh passphrases that could be directly used for login to servers, saying the agent stores passphrases is at least a bit misleading.

what you want is:

• use Key authentication, not passwords
• disable passwordauthentication on the server when you have setup and secured (some sort of backup) ssh access with keys instead of passwords.
• if you always want to provide a short password for login, then don’t use an agent, i.e. unset that environment variable and check ssh_config
• give your private key a password that fits your needs (average time it shoulf take attackers to guess that password vs your time you need overall to exchange the pubkey on all your servers)
• change the privatekey every time immediately after someone might have had access to the password protected privkey file
• do not give others access to your account on your pc to not have to change your private key too often.

also an idea:

• use a token that stores the private key AND is PIN protected as in it would lock itself upon a few tries with a wrong pin. this way the “password” needed to enter for logins can be minimal while at the same time protecting the private key from beeing copied. but even then one should not let others have access to the same machine (of course not as root) or account (as user, but better not at all) as an unlocked token could also possibly be used to place a second attacker provided key on the server you wanted to protect.

all depends on the level of security you want to achieve. additional TOTP could improve security too (but beware that some authenticator providers might have “sharing” features which could compromise the TOTP token even before its first use.

My theory is that you already have something providing ssh agent service

in the past some xserver environments started an ssh-agent for you just in case of, and for some reason i don’t remember that was annoying and i disabled it to start my agent in my shell environment as i wanted it.

also a possibility is tharlt there are other agents like the gpg-agent that afaik also handles ssh keys.

but i would also look into $HOME/.ssh/config if there was something configured that matches the hostname, ip, or with wildcards* parts of it, that could interfere with key selection as the .ssh/id_rsa key should IMHO always be tried if key auth is possible and no (matching) key is known to the ssh process, that is unless there already is something configured…

not sure if a system-wide /etc/ssh/ssh_config would interfere there too, maybe have a look there too. as this behaviour seems a bit unexpected if not configured specially to do so.

since bots are better at solving captchas and humanoid services exist that solve them, the only ones negatively affected by captchas are regular legitimate users. the bad guys use bots or services and are done. regular users have to endure while no security is added, and for the influx i guess it is much more like with the better lock on the front door: if your lock is a bit better than that of your neigbhour, theirs might be force-opened more likely than yours. it might help you, but its not a real but only relative and also very subjective feeling of 'security".

beeing slower than the wolves also isn’t as bad as long as you are not the slowest in your group (some people say)… so doing a bit more than others always is a good choice (just better don’t put that bar too low like using crowdsnakeoil for anything)

Cold fusion is right around the corner!

i thought they’re already at “triple cold² fusion++” ;-)

yet these are never make it to market.

my personal favorite (but not a battery) were two different fake news about fans without any moving parts, one with electricity, conductors and shapes only, the other using ultrasonic somehow, how cool were these lies !!!

https://www.itnews.com.au/news/silent-microchip-fan-has-no-moving-parts-106236

“RSD5 is the culmination of six years of research by Dan Schlitz and Vishal Singhal of Thorrn Micro Technologies”

“Six years of research”, such a cool “product” and now that linked thorrn domain is for sale, how bad!! the world will never profit from their super “cool” invention !!!

“today” other bladeless fans (based on ultrasonic freqs) were anounced: https://linustechtips.com/topic/1471374-not-a-big-fan-new-solid-state-cooler-can-blow-air-with-no-moving-parts/ (“Frore is expecting to start shipping units in Q1 of next year.” which was news from 2022) but did you hear about that cool product beeing shipped yet? i would have, i’m somehow sure, but somehow i didn’t. maybe the “units” they wanted to ship were just something else *lol That article also says: “Frore Systems hasn’t announced any actual computers featuring its Airjet solid-state coolers. But the company is already in partnership with the likes of Intel […]” no actual result, but already partners like intel (intel, how does’nt that already fit !!)

The same nonexisting effect (fan without moving parts), abused (at least) twice. (i’ll just ignore those “bladeless fans” here that officially just have hidden “propellers”) but military says “twice” is already a scheme…

why should it be different for batteries?

if they produce batteries THAT good, they would never sell them but make them available only for rent, to maximise their(!) ROI (and not yours). so i guess it’s yafn - yet another fake news. i might still be wrong however, but i also like to be on the safe side of predictions ;-)

a theory: the richies offsprings startups desperately need other lies than their parents and grandparents who already used up nearly all language-allowed possible lies (as well as nonverbal lies, just watch tv for a while to see it in action) to distract people, companies and govs to ‘invest’ in them instead of i.e. in the future or in the nation, thus new nonexistant technologies is what the richies offspring found best to be their lies about.

like i said:

maybe the root-cause is […] the total lack of any consequences

but you used much more words ;-)

“publicly traded” does not imply that consequences would be impossible.

i see the opposite is true.

one could make that “public trade” also “very” public as in ownerships could only be changed together with a public note of who that new owner of that share is in person and only like not allow ownership changes more than twice a week per person, making investment more profitable than parasitic high performance trade. also the current lack of consequences could be improved by making the shareholders personally responsible for everything that the company does, including going to jail when the ceo left the country to not go there.

that could include making those responsible who owned that company at the time of its crime, making trust in the company way more important than that they can cause damage to society in macroscope just to profit in microscopical bits.

this way the shareholders would have a at least one trigger to actually want to look into who that bullshittalker is they want to let into such a position of “their property”

society should take care who they let do things with “their property” too.

i believe such happens only bcs society lets people into such positions without checking them to be fit in any way for anything except them having a bank account for receiving millions and a lawyer to check contracts and tell them what they should not say in public and receive parts of these millions in return for changing their customers “pampers”.

or maybe that brainfart was just part of a trip on randomly mind altering illegal substances? or maybe a brain tumor? or maybe a brain parasite? or maybe a parasite brain? or maybe just normal capitalism? or maybe a tumor that grows in society?

i guess we will never know for sure.

apple also killed productivity *lol but that has nothing to do with blackburied or … *who the f is intel?

server: arm handy: arm desktop: amd laptop: amd

and happy with it, left intel 20years ago for at that time already obvious reasons why other companies products are better.

work notebook: impediment with a bitten fruit logo on it. i am very unhappy with its lack of stability/deterministic behaviour on even veery low basic things, and guess what, it also has an intel cpu… yeah (f**k), i unwillingly try to use that intel crap for work.

apple might have killed intel, but got infested with releasing crappy products on that path. what a gain!!! 🤦‍♀️

i’ld rather let a zombie go on walking than getting zombiefied while trying to stop it… but tbh its “only work” that is slowed down by the fruitlogozombie (well, am i zombiefied already?) at least that “bitten” part of its logo from now on makes fully sense to me 😁 😂

maybe the root-cause is less the publicly-traded part but rather the total lack of any consequences?

but yes i totally agree, any company publicly traded will get a payed-for-CEO after a while and latest at that point is where no problems are resolved any more, but instead are IMHO always created on purpose.

Having subscriptions for hardware

actually how i understand that model, the subscription would not be for the “hardware” (which you would still have to ‘buy’ and pay for all of its repairs by yourself) but only for the software which would actually block you from using your own hardware if you stop paying the then-later-by-them-to-be-definded-price for the ‘licence’ to use that software, rendering the hardware a useless piece of junkscrap whenever and as long as they whish or their cloud runs on MShitsoft or is maybe ClownStricken, MacAfff’ed, CEO’ed, CTO’ed, Shareholder’ed or such).

That f*up-idea is afaik explicitly NOT a renting model for hardware where they’ld had to make sure that it actually works before you have to pay the rent, but only a licensing software for that only software that is vendor-locked-in on that vendor-poisoned hardware.

As i know myself, i guess i’ll discontinue to buy or suggest any of their stuff for a few decades from now, for that “idea” only.

Have a nice® day without logitech!

Only rate limiting is the effective option.

i doubt that. you could maybe ratelimit per IP and the abusers will change their IP whenever needed. if you ratelimit the whole service over all users in the world, then your service dies as quickly into uselessness as effective your ratelimiter is. if you ratelimit actions of logged in users, then your ratelimiting is limited by your ability to identify fake or duplicate accounts, where captchas are not helpful at all.

at the same expense of bots. they might be cheap, but i doubt that anyway, bots don’t need sleep.

i was answering about that wording (that captchas were “not” about bots but about “stopping automated requests”) and that automated requests “are” bots instead.

call centers are neither bots nor automated requests (the opposite IS their advantage) and thus have no relation to what i was specifically saying in reply to that post that suggested automated requests and bots would be different things in this context.

i wasn’t talking about effectiveness of captchas either or if bots should be banned or not, only about bots beeing automated requests (and vice versa) from the perspective of the platform stopping bots. and that trying to use different words for things, (claiming like “X isn’t X, it is really U!”* or automated requests aren’t bots) does not change the reality of the thing itself.
