nftables rules management noscript

Hi!

I used to use ufw as firewall management, but after struggling with Docker firewall rules, I moved to a custom nftables setup, which ufw couldn't manage([https://www.reddit.com/r/docker/comments/c25rns/docker\_macvlan\_ebtables/](https://www.reddit.com/r/docker/comments/c25rns/docker_macvlan_ebtables/)).

So I created a noscript to provide basic ufw rules with a custom nft ruleset.

Currently, IPv6 needs some work, but IPv4 works great. This weekend I'll add pre/post hooks, so you can run some noscripts before and after applying ruleset.

Comments are greatly appreciated.

cryptsetup defaulting to argon2i

Since the [internet draft](https://datatracker.ietf.org/doc/draft-irtf-cfrg-argon2/) recommends using the argon2id key derivation ("hybrid" mode, having resistance to both GPU cracking attacks and side-channel attacks), I was wondering why cryptsetup, used for LUKS and other disk encryption modes, defaults to argon2i (resistant to side-channel attacks only).

I couldn't find an answer anywhere so I though I'd ask here...

I want learn a bit Linux everyday till I master it!!

Hello, firstly sorry for my bad English!

Many times in my life tried Linux, but it makes me very tired every time, I got stuck in a simple trouble for a lot of time, so that's makes me to go back to windows.

This time I'm serious, I want to learn it well, especially about the terminal, but I'm very busy and only have little time daily to do that like 15-20 minutes. However, through this time I want learn something till I will be comfortable with it.

Are there any good websites, applications, books or tips that's useful with this kind of learning?

note: I'm a computer science student

Thanks Linux community <3

My NVME SSD "Percentage Used:" has hit 224%. What's the highest you've got? Show me your abused SSDs.

So I've got this 250GB Samsung 960 EVO NVME SSD in a computer doing some SNMP performance monitoring where it writes to RRD files every one minute. For those of you not in the know, this is just performance monitoring metrics like disk/network/CPU utilization which is then used to draw graphs.

The system is constantly writing data. I'm abusing the hell out of this consumer-grade drive.

It's notable that the available spare erase blocks is still at 100%, so unless there's something else to wear out (the controller), there's not actually anything "worn out" about the drive at all. It's just that we've exceeded Samsung's warranty claim thresholds by 124%.

So I'm wondering who among you has a more abused SSD? Show us your numbers. Dump your smartctl output like below:

I have xubuntu 18.04-And Can't Install Think or Swim -I already Googled-Any solutions?

It's very odd, I can't seem to install Think or Swim, the linux version, and it's really odd. I've had to get virtual box to get it to work, but want to run it natively. Anybody out there that can shoot me an easy tutorial guide, without having to send my file to the ubuntu server or any of that nonesense. It should not be this difficult. Thanks in advance. Happy weekend to everyone.

Which is the fastest Ubuntu based distro ?

I don't know why but Ubuntu 18.04 stutters a lot on my laptop. I used Ubuntu 14.04 before on my more lower end laptop (4GB RAM, 256GB HDD) but that wasn't a problem.

I have 8GB RAM, 256 GB SSD on my current laptop but Ubutnu 18.04 is extremely slower than I expected.

Need suggestions for a faster Ubuntu variant. Thank you.

force laptop to use battery instead of power per schedule

Is this possible to do in linux on a laptop? Basically to set up a schedule where at certain hours of the day, even though the power is connected, tell the laptop to use battery power instead of external.

Shellinabox and let's encrypt

Hello,

I am unable to run the certs from lets encrypt, it always default to the self signed certificate in /var/lib/shellinabox. I have a symlink the certs from let encrypt and deleted the self signed certificate, every time to restart shellinabox the self signed certificate resuscitates.

I found some documentation, but very unclear... Has anyone done this setup?

PS: The reason I am doing this is so that I have a terminal at work to study for the LPIC series.

FW Update Manager doesnt work in T490s

Hi,

I tried to Update the ME Consumer Update of my T490s via fwupd. After reboot it loads the update Screen but does not install anything. I see the Lenovo Logo and the "please wait while we install the update". After 2 hours nothing installed.

I just see the "press any key to continue" If i press a key, the thinkpad reboots.

What can i do?
