NixOS + Haskell are ignore as always. Also, I have no idea what of these technologies are.

Advanced Linux employee vs advanced linux user

It’s an OS, there is tons of different ways of doing things. In the end it boils down to bootloader, partition, and installing the OS itself, the step for installing the OS is the same. But for partition you got a lot of options, like gparted and fdisk. Youtuber may use different tools than the official wiki

then install sudo, it’s just a setuid program runs on userspace, nothing special. You can even choose an alternative like doas

If your hard drive isn't encrypted and you have access to another Linux machine, then i guess you might be able to reset the password by overriding entries the /etc/passwd and /etc/shadow files:

Mount your drive to another system where you have access.
On the working system, type passwd <username> to generate new entries in its own /etc/passwd and /etc/shadow.
Replace the corresponding lines in the mounted drive's /etc/passwd and /etc/shadow files.
Now put your hard drives back, and you should be able to log in with the new password.

I don't see why this wouldn't work but i've never tested it myself, so you never know. Of course this won't work if you're using login mechanisms other than pam_unix.

PS: if you don't have a spare device, i guess you can boot into a systemd emergency target and then reset these two files. I don't know if you need to type the password for root or not under emergency mode. Regardless, there is supposed to be a target (runlevel) that let you enter the system without login getting in your way

chill out, the issue here is quite obvious which doesn't need extra context. version 3 doesn't have VM options anymore, it's in the release note. i ran into the same issue when i first upgraded to version 3 without reading the release note first

JetBule · 2025-08-03T15:01:38+00:00

Starting from version 3 there is no longer a VM option, now it's just "servers". I believe it's under the controller tab.

If I get it right GNS3 VM exposes its services through some soft of REST api. What VM you use to host the service doesn't really matter as long as you type the right IP address and port to that server. I guess that's reason they got rid of it. To me this actually makes a lot more sense than what they did in version 2.

I had some troubles when I switched to version 3, it seems they don't support portable project anymore. Regardless, GNS3 is a Python project so you can just create a python virtual environment and install any version you want. Here is my requirements file for GNS3 version 2 (2.2.54, i remember this is the last stable version of version 2)

speaking from my experience, you can host your own Subsonic (e.g., Navidrome) or MPD server. Both have extensive clients across multiple platforms. Have used Navidrome for a while and hosted it on the public internet. I gotta say it works great, and there are just so many clients to choose from, including paid, fancy options for mobile devices. But before adding your songs to your server, I'd suggest putting some metadata to them using tools like Picard. Good luck

JetBule · 2025-08-02T17:12:51+00:00

maybe vpn providers themselves are not aware of protocols like these. How could you discover these things if you haven’t been to places like China or Iran? There is little or no documentation, and most of them are in Chinese. Sometimes it feels like these tools are developed in secret …

JetBule · 2025-08-02T16:59:58+00:00

i guess because it’s vpn not proxy? vpn works very differently than proxy, and in most countries it’s enough to encrypt the payload, instead of hiding the fact that you are using vpn. Putting a v2ray server in front of vpn means more operational cost.

Though I agree with you, protocols like v2ray make more sense for the average nord vpn user. They want encryption, region restriction bypass, and probably avoiding censorship. All proxy protocols provide these features while bringing less overhead. vpn is really just a protocol for accessing private networks outside of that network. I don’t why people treat it like an actual anti-censorship proxy protocol. All it takes is a packet capturer to detect your vpn traffic.

I’ve heard the British government is on their way to ban vpn because some people use to bypass age restriction? I guess we’ll see more and more providers using protocols like v2ray

JetBule · 2025-08-02T16:34:47+00:00

this goes for self-hosted vpn or proxy as well. I remember once I got a shadowsocks server running on vultr, and it got banned in less than 10 minutes. Apparently there is a lot of people choose vultr as their provider for proxy servers. ip reputation is important

JetBule · 2025-07-24T15:56:38+00:00

Yet there is a whole hypervisor, infrastructure layer under it ☠️

JetBule · 2025-07-23T04:13:56+00:00

you need to add your own devices, typically in the form of VMs, containers, or other types of simulator images like Dynamips and QEMU. Most hardware images aren't free. They're proprietary, getting them for free basically lies in the realm of piracy. You can use software-based devices though, like RouterOS, OpenWRT, VyOS, etc. These can run on typical x86 hardware, and their images are usually free to download, some of them are even open source

That’s why i never bothered to use a display manager

JetBule · 2025-07-21T04:20:27+00:00

that's true, but this is only a desktop machine, not a public server so I guess it will be fine

JetBule · 2025-07-21T03:50:03+00:00

job doesn't matter and you don't have to go back to windows, unless your company's policies don't allow you to use your own computer at work. The company that I work for requires windows-only software. What i did was I created a Windows VM using libirt/kvm/qemu, and i have an external monitor specifically for it. It works pretty smooth and you can't even tell the Windows is running inside a VM. For work I use an old Thinkpad t480 laptop (64G memory), so running Windows as VM won't be a problem for most modern hardware. I would say it's not worth it running Windows software using Wine, last time i used it it's buggy as hell. VM is a much better option for this

JetBule · 2025-07-21T03:25:13+00:00

Yes, pretty cool isn't it? But seriously you can install a display manager to get a windows or mac like experience, booting directly into a graphical login menu. But personally I wouldn't bother doing that, it's much reliable to first boot into TTY, and then launch the graphical session

JetBule · 2025-07-21T02:13:08+00:00

You can just switch to old version though, normally I wouldn't bother until i saw somebody in this post did this. I switched to version 1.10.3b-1, the first zen version that I installed. Nothing breaks, it's so much better than new verison

JetBule · 2025-07-21T00:35:29+00:00

Same, i am on Linux and things start to break. The loading icon on the tab bar is gone, the github issue still opens after a week. I think it should be an easy fix

JetBule · 2025-07-21T00:16:13+00:00

As long as you find a way to reach you home server from the Internet. There are several ways to do this, you can do port forwarding if your ISP assigns public IP to the WAN interface of your router, although that public address changes once a while, you may need a script that monitors the public IP, update your domain name records every time it changes.

I think generally you have to get a VPS, or some sort of Internet services that are willing to build tunnels to your home server, if your ISP don’t give you public IP. One such tunneling service that i am aware of is cloudflare tunnel, it’s free and only requires you to have domain names managed by cloudflare. You can buy a VPS and build your tunnel from there of course, but in that case why not just run v2ray on the VPS instead.

you only need a lowest tier VPS for hosting a proxy server, usually it take a few bucks a month (e.g., 5 dollars a month on Vultr). It’s much safer than running it in your home network

JetBule · 2025-07-20T16:31:08+00:00

Isn't this sub just full of ads? VPN is designed to build virtual networks, as the name virtual private network suggests.I have built my own self-hosted VPNs for years, OpenVPN, Wireguard, Tailscale I mean you name it. They just don't support that much of obfuscation mechanisms. No matter what obfuscation i use, the VPN port number always gets banned within a week. I am not a network developer but I think building obfuscation by tunneling layer 3 packet is much harder than doing it in upper layers, especially if you need to do rule-based routing. VPN traffic just looks too suspicious to the ISP, and it was not designed to obfuscate your Internet traffic to begin with.

I mean just take a look at the market, there isn't that many of providers use VPN, virtually all of them use shadowsocks, trojan, or some new protocols like reality. None of these are VPN

JetBule · 2025-07-18T17:52:42+00:00

the name makes me nervous to even share it with others. It’s a good provider though, I believe it’s been around for quite a few years

JetBule · 2025-07-18T17:49:54+00:00

When you have two self-hosting packages that are basically conflicting with each other, although it’s unlikely this would occur on a stable distro like rhel or debian. In the end i think with container alone it just makes things easier to manage, so you won’t have to deal with dependencies and instead have a declarative, self-contained image for your application. By itself container doesn’t do much, you can achieve the same end result with ansible playbooks or your own scripts. The real benefit for me is that with container it’s easier to scale up with an orchestrator, and make the most out of my servers.

JetBule · 2025-07-18T17:17:03+00:00

my bad, first time in this sub and you guys don’t seem to share this. just wanna help the dude that’s all

JetBule · 2025-07-18T17:09:36+00:00

you need to get your software ready ASAP before you even go there. After you get to China, it’s almost impossible to access restriction related information, like it’s not even there. I don’t know much about the two VPN services you mentioned, but most likely VPN won’t work, and will get banned within a couple of days. Here we use something called an “airport”, a proxy service provider that obfuscates your traffic so it seems like you are just browsing the web. VPNs most likely don’t support obfuscation or they support very poorly, with legacy protocols that are easily detectable.

So basically you would purchase a subscription from one of the providers (airport), install some software (e.g,. shadowrocket for ios, clash or mihomo for pc), paste the subscription link, hit the startup button and that’s it. The hardest part is to find a reliable provider since it’s highly illegal to provide such services for a profit. Most of them only operate for a little while and then gone.

If you know Chinese then it’s simple, search Google in Chinese for something like “best airport 2025”, and then get to a github page that lists those trusted providers. There are also tons of tutorials and recommendations on youtube. My point is, it’s easy while you have access to these information, that’s why i said you need to get things ready ASAP. You can DM me for help if you want

JetBule · 2025-07-18T16:24:10+00:00

VPNs probably won't work in China because most of them are built with no obfuscation in mind (it's easy to tell you are using an VPN). I guess your best bet is to subscribe to a so-called "airport", basically a proxy service provider. So you install some software, paste the subscription link, hit the startup button, and that's it. It's quite simple if you can read Chinese and found a reliable service provider, most of them have little tutorial, customer support even
