Who said anything about it being standard? I said I know this CAN happen, and I said it was quite some time ago. We can only hope this insanity isn't still in practice anywhere, but I learned long ago that expecting a corporation to NOT do foolish things will give me the same disappointing results as expecting money to come out of my ass. If there's a manager involved, then something on the tech side is going to get fucked up in the name of saving a buck. Therefore I cannot just assume OP gets a normal NAT address, nor can I assume they have any other firewall type device between them and the internet. With limited data, the best I can do is try and provide some general information, hopefully encourage them to ask more questions or provide more specific information, and just hope they don't have a ridiculously stupid ISP that makes things needlessly complicated.

When you say old gear is not cheaper... I take it you're looking for some pretty modern stuff? When I decided to get more involved in photography I picked up a Canon Ti4 used from ebay. It was about 6 years old at the time and I picked up a good one for around $250. The same thing with lenses, everything I have is from ebay and everything was relatively cheap (although I'd love to get one of those Sigma 600mm lenses, but oof!). Yeah my body is closer to 12 years old now but I still use it all the time and it's done well for me, plus the EF mounts are common as hell, and all of my lenses have image stabilization built in.

If you're having trouble getting trash photos, maybe check back with this group on what lenses match the shots you're trying to take? There's definitely some garbage lenses out there, and early-on I discovered Canon's own 300mm EF lens have two different models that look identical, but there's a huge difference in the quality between them (which is why the good one costs twice as much, even used).

One good thing about Canon is that you have Magick Lantern available. Most of us can't afford the functionality that this software provides for free! If you want to stick with Canon and get the best bang for your buck, check to see which bodies ML is compatible with to narrow down your selections. After that I would check the lens mounts to see what other mounts can be adapted to fit a body to give you the widest selection of lenses possible. This is usually a one-way street due to focal length so it might pay to choose a body with greater adaptability.

You're right, it doesn't make any sense. And it didn't make any sense at the time either. After setting up the router with a laptop, I moved the connection to the firewall but it refused to connect. When I finally got ahold of tech support they said the connection locks into the first machine that logs in and they had to release it so I could connect the new machine. And just like that the firewall was given a routable IP address and connected to the internet. Stupidest thing I ever heard of, but that's how they were set up. Now this was around 15+ years ago and I would certainly hope nobody is doing that crap today, but apparently that was their brilliant method of limiting how many devices could get online at once.

I'll have to check it out, thanks for the link! [Edit] oh it's a book, not an online article.

Yeah this article is really long, and a lot of it is over my head (especially the math), but they have brought up several interesting points and provided a much easier-to-understand model of the holographic universe. I mentioned this theory in another post here a few months ago and was basically shut down with claims that this wasn't even possible and the theory had been long-discounted, and yet here we are with modern work still plugging away at the concept. It makes me appreciate just how much hell all scientists go through when they posit theories that contradict other people's personal beliefs.

What are you talking about? You're assuming that every residential router is going to have some kind of firewall enabled by default (they don't). Sure, if OP has a router that provides a basic firewall type service then it will likely block all incoming unauthorized traffic. However OP is specifically talking about a linux-based firewall and hasn't specified if they have a router-based firewall service in place as well so we can only provide info on the firewall they specified. And if you look at UFW, the default configuration is to allow outgoing traffic and block all but a very few defined incoming ports.

You're also making the assumption that OP is using NAT, when that is not always the case for all ISPs. Some are really annoying with their setup in that they give a routable IP to the first computer that connects and don't allow any other connections (I had that setup once with Comcast). In this case, you wouldn't even need to define port-forwarding to get directly to OP's computer -- and any services they might be running. This particular scenario is especially dangerous for home computers and I really hope no legitimate ISP is still following a practice like this, however I don't take anything for granted.

Regardless of what other equipment OP has, UFW is going to provide FAR better defaults and configurability when compared to a residential router that is simply set up to create the fewest support calls to their ISP.

 

A 1930s-era breakthrough is helping physicists understand how quantum threads could weave together into a holographic space-time fabric.

You've got it backwards. A firewall blocks everything, then you open up the ports you want to use. A standard config would allow everything going out, and block everything coming in (unless you initiated that connection, then it is allowed).

So the question you should be asking, is what services do you think you're going to be running on your desktop that you plan to allow anyone on the internet to get to?

From my own experience it was more about being a solution in search of a problem. I see some comments about how the old init system was so horribly broken, and yet the reality was it worked perfectly fine for all but some very niche situations. The only advantage I have ever seen with systemd is that it's very good at multitasking the startup/shutdown processes, but that certainly wasn't the case when it first arrived. For example I had a raspberry pi that booted in 15 seconds, and when I loaded a new image with systemd it took close to two minutes to boot. And there were quite a lot of problems like that, which is why people were so aggravated when distro admins asked the community for their thoughts on switching to systemd and then changed the distros anyway. This also touches on the perception that the "community" accepted it and moved on -- no, systemd was pushed on the community despite numerous problems and critical feedback.

But we're here now, systemd has improved, and we can only hope that some day all the broken bits get fixed. Personally I'm still annoyed that it took me almost a week to get static IPs set up on all the NICs for a new firewall because despite the whole "predictable names" thing they still kept moving around depending on if I did a soft or hard reset. Configuring the cards under udev took less than a minute and worked consistently but someone decided it was time to break that I guess.

Whatever happened to Russia's "next-generation" ICBM a couple years ago that was supposed to put the US's technology to shame? Did it ever get off the ground, or was that another example of "Russia claims..."?

Green felt top hat with a size tag stuck in the band. Oof that's been about 20 years ago now.

Another suggestion... have you considered if something in particular might be preventing you from getting good sleep? In my case, I've had restless-leg for quite awhile which was managed by doing some stretches before bed as needed. After a really car car accident, that went into overdrive, the stretches made no obvious difference and so I didn't think that was an issue any more, but apparently I was tossing and turning all night. I'd sleep for 9+ hours and wake up a zombie.

After years of this I finally talked to my doctor about it, we discussed a lot of things and I mentioned how I had previous had the problems with my leg pains at night. He decided to try treating this symptom and suddenly I started getting real sleep again. By now it has gotten so bad that if I forget to take my pills at night, my legs absolutely scream at me the moment I lay down in bed. Yeah I'll be on this med the rest of my life, but I'm getting good sleep now and feeling energetic the day.

The point is, your issue may be something you have already dismissed without realize fully how it affects you. When an unknown problem comes up, sometimes you just have to go back and reevaluate everything.

OK yeah, I wasn't sure if it had a way to collect debs from other sources. I've been using it for years to locally cache the standard Debian repos so I don't need to re-download packages every time I update my various servers and VMs, but I haven't really tried using it for anything beyond that.

Sorry to ask, but isn't this basically the same thing as apt-cacher-ng?

 

I would love to have them light up like a scoreboard as each representative takes the floor, showing all of the commandments they have broken. If people want so badly to bring religion into politics then lets just show them exactly who they've been voting for. Maybe we can get the news networks in on this too, displaying it on the side of the screen similar to a sporting event.

 

Marjorie Taylor Greene, the bastion of factual information, has once again shown the nature of her character by claiming that peaceful protestors at the Capitol are in fact an "insurrection of terrorists". Don't you see all the violence and mayhem being caused in this video clip? No, me either...

If you want to make such bold comparisons, lets start out by checking how many people are running for their lives or the number of deaths involved between these two events. Or maybe we should be asking why MTG thought it was an "honor" to meet with the people responsible for murder and the attempt to destroy our democracy?

 

I've seen the occasional blip here, but this is the first time I've seen a complete outage of this instance. Hoping @Salamander wanders through and gives us the scoop?

 

I have an annoying problem on my server and google has been of no help. I have two drives mirrored for the OS through mdadm, and I recently replaced them with larger versions through the normal process of replacing one at a time and letting the new drive re-sync, then growing the raids in place. Everything is working as expected, with the exception of systemd... It is filling my logs with messages of timing out while trying to locate both of the old drives that no longer exist. Mdadm itself is perfectly happy with the new storage space and has reported no issues, and since this is a server I can't just blindly reboot it to get systemd to shut the hell up.

So what's the solution here? What can I do to make this error message go away? Thanks.

[Update] Thanks to everyone who made suggestions below, it looks like I finally found the solution in systemctl daemon-reload however there is a lot of other great info provided to help with troubleshooting. I'm still trying to learn the systemd stuff so this has all been greatly appreciated!

 

Just in case there are others like myself who rarely check reddit any more, I thought it would be helpful to cross-post this. It won't look like much unless you have the solar eclipse glasses, but I plan to break out my tracker and camera (with solar filters!) to try and get some pics.

 

I have been struggling with this for over a month and still keep running into a brick wall. I am building a new firewall which has six network interfaces, and want to rename them to a known order (wan[0-1], and eth[0-3]). Since Bullseye has stopped honoring udev rules, I have created link files under /etc/systemd/network/ for each interface based on their MAC address. The two WAN interfaces seem to be working reliably but they're not actually plugged into anything yet (this may be an important but untested distinction).

What I've found is that I might get the interfaces renamed correctly when logging in from the keyboard, and this continues to work for multiple reboots. However if I SSH into the machine (which of course is my standard method of working on my servers) it seems to destroy systemd's ability to rename the interface on the next boot. I have played around with the order of the link file numbers to ensure the renumbering doesn't have the devices trying to step on each other, but to no avail. Fixing this problem seems to come down to three different solutions...

  • I can simply touch the eth*.link files and I'm back up afte a reboot.
  • Sometimes I have to get more drastic, actually opening and saving each of the files (without making any changes). WHY these two methods give me different results, I cannot say.
  • When nothing else works, I simply rename one or more of the eth*.link files, giving them a different numerical order. So far it doesn't seem to matter which of the files I rename, but systemd sees that something has changed and re-reads them.

Another piece of information I ran across is that systemd does the interface renaming very early in the boot process, even before the filesystems are mounted, and that you need to run update-initramfs -u to create a new initrd.img file for grub. OK, sounds reasonable... however I would expect the boot behavior to be identical every time I reboot the machine, and not randomly stop working after I sign in remotely. I've also found that generating a new initrd.img does no good unless I also touch or change the link files first, so perhaps this is a false lead.

This behavior just completely baffles me. Renaming interfaces based on MAC addresses should be an extremely simple task, and yet systemd is completely failing unless I change the link files every time I remote connect? Surely someone must have found a reliable way to change multiple interface names in the years since Bullseye was released?

Sorry, I know this is a rant against systemd and this whole "predictable" naming scheme, but all of this stuff worked just fine for the last 24 years that I've been running linux servers, it's not something that should require any effort at all to set up. What do I need to change so that systemd does what it is configured to do, and why is something as simple as a remote connection enough to completely break it when I do get it to work? Please help save my sanity!

(I realize essential details are missing, but this post is already way too long -- ask what you need and I shall provide!)

tl;dr -- Systemd fails to rename network interfaces on the next cycle if I SSH in and type 'reboot'

 

Your dreams and imagination evolved as a view into another universe. As with the current beliefs, you cannot decipher technical information -- no words in books, no details of how devices work, so even if you can describe things you see from another place, you could not reproduce a working version.

Now how do you convince others that the things your are seeing are really happening without being labeled insane? And how could you use this information to benefit yourself or others? Take a peek into the multiverse to see how other versions of yourself have solved these problems...

 

I was reading another article which discussed taking measurements of distance stars at 6-month intervals to create a 3D map of their relative positions and direction of movement. This got me to thinking... has anyone proposed 'dropping' stationary satellites outside of Earth's orbital path for continuous monitoring even when our planet is no longer in that spot? It seems like such an arrangement could provide constant monitoring of things that are happening on the far side of the sun, and they could each act as a relay to each other, bringing the signals back around where we could receive them.

It could be fascinating to be able to constantly monitor the path of know comets, or perhaps even to detect large meteors which are safely away from us now but might some day pose a threat. Studies like mapping star positions could rapidly expand with the availability of continuous data feeds, and I'm sure if such a tool were available scientists would come up with a host of new experiments to try.

A couple other things also come to mind. First off is radio telescopes, which can gather more sensitive data by having sensors further apart. Of course in this case they would only be able to peer in two directions unless you set up the array to rotate as a singular ring (which greatly increases the complexity). The other idea was that I know some phenomena are so large that it takes a huge array of telescopes or sensors to even detect them, and something this large could detect truly astounding low frequency events. Throw in some gravity detectors and watch as the waves propagate through our solar system.

I'm just thinking there's a lot of possibilities here and a lot more data could be collected if we could drop four or eight satellites along the way. I would assume the idea has been proposed before, I just didn't know if this is even feasible?

 

Turns out both grow in my area, and look identical to this when young. Yikes! So based on a post yesterday, I took this outside and sliced it in half. So far it looks promising (I think?) and I'm not dead yet.

This was found growing in a Colorado yard near the base of an elm tree, in an area where there are also rotting cottonwood roots. Altitude is right at 5000 feet. It wasn't my yard so I'm not sure how many days it may have been growing before I picked it today. I have put both halves in the fridge for now, is there any other information I can provide to help identify it?

I've been running systems up to Buster and have always had the 'quiet' option in the grub settings to show the regular service startup messages (the colored ones showing [ok] and such but not all the dmesg stuff). I just upgraded a server to bullseye and there are zero messages being displayed now except an immediate message about not being able to use IRQ 0. Worse, google can't seem to find any information on this. If I remove the quiet option from grub then I see those service messages again, along with all the other stuff I don't need.

What is broken and how do I fix this issue? I assumed it would be safe to upgrade by now but this seems like a pretty big problem if I ever need to troubleshoot a system.

[Edit] In case anyone else finds this post searching for the same issue… Apparently the trick is that now you MUST install plymouth, even on systems that do not have a desktop environment. For whatever reason plymouth has taken over the job of displaying the text startup messages now. Keep your same grub boot parameters (quiet by itself, without the splash option) and you will get the old format of startup messages showing once again. It’s been working fine the old way for 20+ years but hey let’s change something just for the sake of confusing everyone.

[Edit 2] Thanks to marvin below, I now have a final solution that no longer requires plymouth to be installed. Edit /etc/default/grub and add systemd.show_status=true to GRUB_CMDLINE_LINUX_DEFAULT. In my case to full line is:

GRUB_CMDLINE_LINUX_DEFAULT="quiet systemd.show_status=true"

Don't forget to run update-grub after you save your changes.

First pics of my first pins. I cut slits in the bag on Sunday and saw the first pins appear yesterday morning, now they're growing fast. This clump is already a full inch (25mm) tall, and I have four openings in the bag that are all pinning. I've been misting them a couple times a day but now I'll be working from home until next Monday so I can try to spray them more often.

For anyone who hasn't seen my previous posts, I started out with a very small sample of spawn from ebay just over two months ago. I expanded that out in jars of rye berries and popcorn kernels, and then on July 4th I split a jar between two fruiting bags with pasteurized straw (I also have two bags of blue oysters and opened one of those on Sunday, but no pins from it yet).

This is my first time trying to grow mushrooms so I've been researching and asking questions every step of the way, but so far so good! I also have never tasted oysters before so that will be a new experience too. Now I just have to temper my impatience until it's time to harvest...

[Update] Adding a second pic this morning. This is about 12 hours later and they've grown significantly again. For reference, the bag is about the size of a sheet of paper.

[2nd update] It's been five days now since I opened the bag for fruiting. Here's a pic of what the mushrooms currently look like. As far as what I've read, I expected them to get MUCH larger than this, but with the upturned caps I really believe these are done growing and should have been harvested yesterday (note this image shows the largest clump of the group). Any thoughts?
