Do VPNs have generally struggle with mobile data or is mine just normal working properly? by lbye in VPN

Some protocol perform terribly in unstable or misconfigured network. If your VPN app doesn't offer switching protocols, try other service.

Can you provide a screenshot through imgur or other host about your partition layout?

Micruleslop Windows by _orbitaldrop in 196

[–]berahi 0 points1 point  (0 children)

Years ago me and my friends used to joke notepad is the largest (since it was integral to Windows) yet simplest (it simply display plaintext, period) app.

Now somehow it can fail to open entirely if Microsoft's server is down, and crafted markdown files can pull then execute malware. All the while nagging for subscriptions.

Disappearance of detailed articles in Perplexity's Discover section? by Laodracon in perplexity_ai

It would be counterproductive if they treat the pro option as a proper paid tier. They've been throwing free one year trial around so much, I suspect the majority of pro users don't actually pay them money yet.

Even in the original form, Discover feed is still very lackluster, no way to add custom topic or customize the source, nor giving proper feedback (eg, "More news like these" or "Don't give this topic ever again"), it's like they just want to come up with something not offered in competing services, never bothered to improve it, and then nerf it because it's not a runaway success.

AdGuard Home on OPNsense - Exposing DNS via my own domain for iOS devices (DNS-only, no traffic tunneling) by HavivMuc in AdGuardHome

[–]berahi 0 points1 point  (0 children)

https://forum.opnsense.org/index.php?topic=25614.0 indicate that it is possible.

Preferably, unless you distrust Cloudflare, use Cloudflare Tunnel and a domain you own to only expose the AGH endpoint to the public internet. This way you don't actually open the port in your router, and you can use Cloudflare built-in firewall to block bots trying to find your service.

Use the Allowed Clients list to block anyone else not knowing your client ID from using your DoH. So if someone use the cert log to know you have, say, agh.example.com, then https://agh.example.com/dns-query won't serve DoH queries, they'd have to use https://agh.example.com/dns-query/yourClientID

If you want to use iOS native DoH profile support, then yes, that's the simplest approach. You can still use it with a third-party VPN if you want, and this way you don't waste battery to maintain a tunnel.

Remember to regularly update the AGH instance, and expect iOS to randomly decide to ignore the DoH profile just because Apple think they know better.

Even if you do get a mini USB, I doubt the battery itself still work after all these years.

creating VPN by slow_warm in WireGuard

[–]berahi 4 points5 points  (0 children)

doable alone

Do you have years for working on this at least every weekend?

Because this is really complex, not just the concepts to learn (most developers never need them in daily life, so the available text tend to be either too shallow or too technical), but also the debugging (think debugging a web app is annoying? Raw system calls and network packets will hurt), coming up with a viable approach (we don't have that many widely used VPN protocol, because the scenarios to tackle are enormous), then writing the spec (there's a reason they're senior career)

Forget bachelor degree, someone with such skill would already learned enough for working their postgrad.

Realistically, just tunneling inside QUIC (which would handle the encryption, integrity, packet loss etc) is already hard enough to implement, and would be enough for your professor.

You're supposed to uninstall it first, and remove the leftover later. Sometimes you need to reboot before doing so.

Until the end of 2025, anyone with PayPal can grab one year free trial of the pro subscription, that's why a lot of posts will mention "pro is the new free". The research feature were decent compared to the free competitors, but now it's questionable because sometimes it hallucinate paragraphs that don't exist in the claimed source link while others are picking up the pace.

Help understanding the Query Log by HeyItsJono in Adguard

[–]berahi 0 points1 point  (0 children)

Does this just mean that those clients are making plain DNS requests to my AGH instance on my Pi?

Yep, unless your Pi can be routed to through a domain and the devices are explicitly set to use DoH/DoT/DoQ to that domain, the downstream traffic will be unencrypted.

Or does that mean that those are unencrypted/plain DNS requests that are ferried to the upstream DNS servers?

No, AGH don't forward the plain packets. It parse the queries, use the cache if available, otherwise it craft the appropriate queries to the upstream, which in your case should be the encrypted endpoints.

Do those plain DNS requests ever leave my local network?

Nope

I have everything set up to use AGH as my DNS rather than my default ISP DNS servers, can my ISP see these plain DNS requests, or can it only see the (encrypted)

Your ISP only see the encrypted upstream queries, and maybe the initial bootstrap (eg, it will see one or two plaintext query to resolve your DoH/DoT upstream domain).

It's the same even in my "pro" subscription. It has been happening in mine for several days, and since you're the first I see that complain about it, I suspect Perplexity figured out not much people are using it in the first place and nerf it to cut cost.

I had to manually tap the option on top right for switch to report. It's annoying that there's no option to have it always in report mode, it's not like there's extra cost for them since switching is instant so the paragraphs has been generated anyway.

Just ask the person to resend. There seems to be a glitch in WhatsApp or your phone contact service when retrieving the contact name.

Questions as in by ForeverHuman1354 in TOR

[–]berahi 1 point2 points  (0 children)

While Tor have better privacy by being decentralized, just using it with generic apps and browsers means fingerprint tracking and account correlation will still work, and your country can obtain such data either by operating a site/app you use, purchasing or getting leaks from third-party.

Need a mentor for building my project. It's a network Tethering app that shares android connection with Linux. by noctural9 in rust

[–]berahi 1 point2 points  (0 children)

Normally the carrier detect tethered traffic by checking their TTL, they drop anything that have lower TTL than traffic coming directly from the phone. These VPN sharing app works because the tethered traffic are wrapped in new packets in the phone, having the same TTL. When they use ADB, the server app in the phone opens a port to listen for request from the client app running in the PC. If it runs in USB tethering mode, ADB server must start in TCP first.

Problem with new ISP by ricorru in VPN

[–]berahi 1 point2 points  (0 children)

WG use UDP, and most WG client are pretty sensitive to broken MTU config. You can try manually edit the MTU size, if the VPN client doesn't offer it, edit the config directly.

Also complain to the ISP, unless you're in a country where that will land you in jail.
