• hack phones remotely just knowing it's phone number
• Intercept 2FA sms
• Intercept phone calls
• Reroute phone calls
• Geolocation of a target

I dunno if it has already been posted/discussed here but this kinda blew my mind ! Sorry there's a lot of clickbait but the general subject is interesting...

I never heard of SS7 and have actually no idea how the whole phone system communication works but that's kinda scary...

Yes we are probably not the first target with this "hack" nor is it as easy as exposed in this video and nor do we have 14k $ to spend on this, but that's not out of reach for some people. I mean it's not as expensive as Pegasus and people with the mean and some good stable income can probably misuse this system for targeting specific vulnera

Hello everyone :).

Trying to keep it short, cause after 2 days of troubleshooting I'm a bit tired and really confused on what happened here... Maybe it's my lack of understanding about Legacy BIOS/UEFI/EFI/Bootloader/GRUB... But that was really an odd "issue" that resolved by itself?

Intro

My 15 years old laptop, an Asus N76V, is still going strong, though It's purpose is not the same as a few years back. It's working great as a mini-server to host docker containers, DNS server, firewall, wireguard tunnel...

Space left on my volume group (LVM) was getting tight so I decided to install a new Samsung 1TB SSD into it's second slot. As easy as it is, I though this would not take more than 30 minutes...

Old SSD just vanished from boot option in bios.

After booting into BIOS to see if the new SSD is recognized, everything seems okay, however my primary SSD containing the Bootloader and system just vanished as boot option?? I was not to angry about it because i

My question was very badly written but the new title reflect the actual question. Thanks to 3 very friendly and dedicated users (@harsh3466 @tuna @learnbyexample) I was able to find a solution for my files, so thank you guys !!!

Hello :)

There isn't any community about note taking where I could post my question and no this is not a "What's the best note taking app" question...

I'm getting tired of maintaining my Obsidian vaults... Somehow I'm fighting to get it right and obsidian seems to fight back. I've got 4 vaults of the same subject and I always end to make a mess out of it and make a fresh one... Also my notes a scattered in all direction and the more my knowledge base grows the less I seem to be able to find something...

This is probably a me problem rather than Obsidian issue. The way I'm taking notes are not compatible with Obsidian. IMO Obsidian's defaults configuration are bad and visually not appealing. Sure customization in Obsidian is "endless" but digging in the HTML code to change the style or adding plugins to somehow get something visually appealing seems more like a chore than actually taking notes.

Here I'm again roaming the web for a Note taking app the could fit my needs and after t

Heyha ! I just came across a very odd issue/bug that somehow resolved by itself without knowing who or what was the culprit.

For context, YouTube doing his thing making nearly all public instances obsolete, I'm self-hosting a Piped instance in my homelab via Docker.

Everything is going smoothly, self-signed certs, traefik, accessible via Wireguard outside of my network, and and and !! LibreTube connects without any issues to my Piped instance on my Android phone and so does RiMusic.

However, in RiMusic when I was trying to access my synced Piped playlists, RiMusic went crazy and my playlist seemed to be in a query loop were I was unable to play any songs and was flickering alot.

TIL something new... My hate for MacOS took over common logic. 2.8GB, 3 seconds file transfer on USB was to beautiful to be true. After some further investigation and hints from @[email protected] @[email protected] I learned that Linux writes to cache before writing it to the device, to see whats happening in the background: sync & watch -n 1 grep -e Dirty: /proc/meminfo.

Still, the transfer speed on Linux was slightly faster than on MacOS. My rant was unjustified, It just my fault for being clueless on some more advanced Linux stuff. But I learned something new today, so this post was actually helpful !

Howerver, I still hate MacOS and will probably give Asahi remix a try.

Thanks to everyone !

Hey guys ! I'm getting tired/bored of MacOS' shenanigans... Yesterday was the last drop that make me think of trying an alternative.

Hi everyone !

Intro

Was a long ride since 3 years ago I started my first docker container. Learned a lot from how to build my custom image with a Dockerfile, loading my own configurations files into the container, getting along with docker-compose, traefik and YAML syntax... and and and !

However while tinkering with vaultwarden's config and changing to postgresSQL there's something that's really bugging me...

Questions

• How do you/devs choose which database to use for your/their application? Are there any specific things to take into account before choosing one over another?

• Does consistency in database containers makes sense? I mean, changing all my containers to ONLY postgres (or mariaDB whatever)?

• Does it make sense to update the database image regularly? Or is the application bound to a specific version and will break after any update?

• **Can I switch between one over another even if you/devs choose to use e.g. MariaDB ? Or is it b

Edit

After a long process of roaming the web, re-runs and troubleshoot the script with this wonderful community, the script is functional and does what it's intended to do. The script itself is probably even further improvable in terms of efficiency/logic, but I lack the necessary skills/knowledge to do so, feel free to copy, edit or even propose a more efficient way of doing the same thing.

I'm greatly thankful to @[email protected], @[email protected], @[email protected] and Phil Harvey (exiftool) for their help, time and all the great idea's (and spoon-feeding me with simple and comprehensive examples ! )

How to use

Prerequisites:

• parallel package installed on your distribution

Copy/past the below script in a file and make it executable. Change the start_range/end_range to your needs and install the parallel package depending

Hi everyone :).

Just getting started with Manjaro as daily drive to get some easier arched based distro. Except for the LVM bug with calamares everything is pretty smooth :).

But at first boot, I saw they have added their personal Manjaro logo on boot and I directly though of the bug exploit logoFAIL I heard a few month ago and It made me curious if this is something that could be exploitable by Manjaro.

Probably not, this would harm their image and hard worked system, but I'm still curious... If someone smarter/more knowledgeable than me could chime in and give some valuable information on this topic regarding Manjaro, I would really appreciate it !

Thank you !

Hi everyone.

I'm curious to understand what could happened to simpleX if the new "security" plan in EU gets voted?

Because I'm not versed enough with the political and legal wording in thoses papers I've got a hard time to actually understand.

• Will simpleX be obligated to comply?
• Will simpleX retire from EU?
• Would It be illegal to use simpleX if the bill passes?
• Could we still use simpleX with a proxy/VPN from a country outside of EU?
• ...

I'm genuinely concerned about what I'm reading here and there on lemmy... I hope someone could give me some interesting point of view.

Thanks.

Hello everyone ! Nobody seems to have an answer on [email protected] (or maybe they are not interested because it's an enteprise network community?) and [email protected] seems dead?

Anyway, If anyone could guide me or direct me to the right direction, I would really appreciate it !

TL:DR

What is encapsulated into the frame that makes everyone understand: "OHHH that’s for 10.0.0.8, your docker container on bridge network br-b1de on the veth2b interface !!! "

Hi everyone !

I'm scratching my head in finding an actual answer on how virtual networking in docker actually works (mostly on the packets/frame level) or some good documentation to improve my understanding on how everything fits together.

Because I'm probably lacking the correct network terminology I made a simple network topology of my network. Don't hesitate to correct any network mistake.

Hi everyone :)

It's time to switch and give my home network a proper minimal hardware upgrade. Right now everything is managed by my ISP's AIO firewall/router combo. Which works okayish, but I'm already doing some firewall/dns/VPN stuff on my minimal spare laptop server to bypass most of my ISP's restrictions. So it's time to get a little bit "crazy" !

While I do have some "power user" knowledge regarding Linux/server/selfhosted services/networking, I'm a bit clueless hardware wise, specially regarding my ISP's 2.5G ethernet port.

I do have a 5giga connection from my Internet provider (Obtic fiber) which is divided into 4 ethernet ports (Eth1 2.5G, Eth2 1G, Eth3 1G, Eth4 0,500G or something in that range). And right now the Eth1 port is connected through an old 1G switch.

1. To take full advantage of my ISP's 2.5G ethernet port do I need a router AND a switch capable of 2.5G througput ? Or only the router and the switch is going to divid it accordingly between all connected de

Hi everyone !

Right now I can't decide wich one is the most versatile and fit my personal needs, so I'm looking into your personal experience with each one of them, if you mind sharing your experience.

It's mostly for secure shared volumes containing ebooks and media storage/files on my home network. Adding some security into the mix even tough I actually don't need it (mostly for learning process).

More precisely how difficult is the NFS configuration with kerberos? Is it actually useful? Never used kerberos and have no idea how it works, so it's a very much new tech on my side.

I would really apreciate some indepth personal experience and why you would considere one over another !

Thank you !

Hello !

Getting a bit annoyed with permission issues with samba and sshfs. If someone could give me some input on how to find an other more elegant and secure way to share a folder path owned by root, I would really appreciate it !

Context

• The following folder path is owned by root (docker volume):

/var/lib/docker/volumes/syncthing_data/_data/folder

• The child folders are owned by the user server

/var/lib/docker/volumes/syncthing_data/_data/folder

• The user server is in the sudoers file
• Server is in the docker groupe
• fuse.confhas the user_allow_other uncommented

Mount point with sshfs

sudo sshfs [email protected]:/var/lib/docker/volumes/syncthing_data/_data/folder /home/user/folder -o allow_other

Permission denied

Things I tried

• Adding other options like gid 0,27,1000 uid 0,27,1000 default_permissions...
• Finding my way through stackoverflow, unix.stackexchange...

Solution I found

1. Making a bind mount from the root owned path to a n
