Redirecting a command to a running process? in c/linux@lemmy.ml
[–] GlassHalfHopeful@beehaw.org 2 points 1 year ago

Good to know about the main proc. I wasn't aware. And it is indeed set to auto restart. I just hadn't realized the stop alone would trigger that. I had figured I would need to take the additional step.

YEEEESSS!!!! THIS!!! Thank you! I've been able to hobble together a script now that I have a Synology automated task calling early each morning after world backups are complete. I'm so very grateful to you all. I've learned a lot. A proper "stop" is being issues now which reduces the chance of world corruption which would make my family very very grumpy.

Here's the script just in case someone finds themselves in a similar situation as me. This is not my wheelhouse and it's not pretty. I know it can be better, but I've spent too much time on this as it is and need to go fix a washing machine now. Ugh...

#!/bin/bash

# Define the countdown duration in seconds
countdown_duration=20

# Function to send a message to the Docker container
send_cmd() {
  cmd="$1"
  sudo sh -c "echo '$cmd' | socat EXEC:'docker attach mcbe-world',pty STDIN"
}

# Announce
announce_text="Daily server restart commencing in $countdown_duration seconds..."
send_cmd "say $announce_text"

# Perform the countdown
for ((i = $countdown_duration; i >= 1; i--)); do
  #echo "Restaring in $i seconds"
  countdown_text="Restarting in $i seconds"
  send_cmd "say $countdown_text"
  sleep 1
done

# Gracefully shutdown server
#  Note: stopping forces the mcbe container to restart on it's own. 
#  Not sure why that's the case, but it's the end result I want...
send_cmd "stop"

P.S. I really need to figure out how to get the RCON solution working because that would be a more elegant way to handle things.

P.P.S Example run (yes, the timing and spelling were updated after this screenshot 😁)

Yeah. I see this as being a problem. I was curious how it comes into play.

The popularity of a show really needs to be taken into account.

Well,RCON has not fared well. Afaik, I've set things up correctly but the client I'm using (mcrcon) keep returning Error 111: Connection refused.

  • This post got me to direct things to the right IP which I could get with docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mcbe-world.
  • docker port mcbe-world shows that the rcon port is open
  • the server.properties files for the mc server has the relevant rcon lines

This looked so promising.

Via SSH, I can indeed use docker attach and from within I can issue a stop for MC server. Works fine.

However, the Synology task scheduler via DSM doesn't seem to be able to similarly attach and then issue the stop command. I get this back via email (for when a scheduled task fails):

Task Scheduler has completed a scheduled task.

Ooh. I was not aware of the RCON protocol. Looking into now. This may be the exact thing I need. Thanks for the lead.

docker exec mcbe-world just gives access to the container so commands can be executed. /stop is a specific command for the MC server running in that container. The process is already running and I am trying to figure out how to issue a command to it... and the other comment in this post referencing "rcon" might be a solution...

Note: Still trying to navigate communities here on Lemmy to replace those from Reddit. If there is a better place such a question, I would welcome the suggestion.

I'm running a Synology NAS, which uses some flavor of Linux distribution. From there, among everything else running, I have a docker container hosting a Minecraft Bedrock Server. The MCBE server is great for fun, but not so great for resource usage. To handle this, most folks setup something to schedule the server to restart.

Within Synology, there is a task scheduler where I can run a user-defined script to restart the whole container: docker restart mcbe-world

This works, but it's a dirty reboot though. I worried about corrupting the world (which I do regularly backup). From within the Minecraft server terminal, the /stop command will gracefully shut it down.

I can't update the container with another application, like screen, because each MCBE update means replacing the entire container (and so destroying the changes). I am looking to somehow redirect a command to the server if possible.

Using docker exec -it mcbe-world , I can execute what I want within the container.

The person here said, one can "inject commands by running the command as the appropriate account and redirecting it into the server" and they gave the example sudo su -s /bin/bash -c "echo say foobar > /run/service@name" Unfortunately, this isn't so clear and straight forward to me.

Would anyone here be able to articulate this more clearly for me or have an idea as to how I might issue that /stop command from the Synology scheduled script BEFORE restarting the container?

Thanks!

it’s a ridiculous loophole. They are literally saying, “I have this thing that’s so valuable, but I ‘accidentally’ threw it away, it’s worthless now, I need to mark this down as a loss.” They are destroying their own products for tax purposes.

This. ☝

If this is accurate, then it would make a hell of a lot more sense. But... it sounds like these "residuals" need to be payed out differently because this sucks for consumers and... honestly... I think for those that poured themselves into making the content in the first place.

But imagine Willow to be entirely Disney. I imagine the tax benefit of cutting it is the best answer to my question, but hell... gah

Would you all explain to me how removing content we expect to have access to is a "cost savings" measure?

The following is from the Willow Wikipedia page, which led me to the linked URL:

The series was removed from Disney+ on May 26, 2023, amidst a Disney+ and Hulu content removal purge as part of a broader cost cutting initiative under Disney CEO Bob Iger.

I've been abroad for a month and earned some time off afterwards. One of my kids reminded me that we never finished Willow, so I said "let's do it now!" The show wasn't perfect for many reasons, but I wanted to finish it for nostalgia's sake and my child legit found it interesting. Lo and behold, the series isn't on Disney+ any more!

A quick search later, I see the above referenced quote linking to the article associated with this post... which only made things worse. The Mysterious Benedict Society was something my whole family could watch and enjoy without arguments! Turner and Hooch was dorky, but something my youngest loved and it was a super safe and easy pick for us bond over.

This post isn't about whether the shows are good. And it isn't about how nearly every show I like ends up cancelled. The point is that I paid for access, they were then quietly removed (for various platforms), and I have zero understanding as to how this saves these companies money.

Would someone explain?

P. S. Yes, I know this is old news. However, this is just how I am. I'm not up to date with anything in the entertainment world. I intentionally wait a few seasons for things because I loath when shows are cancelled after a season. (I'm looking at you, Firefly.) I'm the same way with books, often waiting to read a trilogy after its published because I don't like the wait in between books. (Thanks, Rothfuss).

I just don't take cancellation wells, especially when I was on top of everything including summer podcasts and such. (Now anything with the names Abrams, Lindelof, or Cuse makes my skin crawl.)

I know. I'm weird and stuff.

Climate activist faces 10 years in jail for a fake letter 'canceling' an oil industry conference | CNN (www.cnn.com)
 

Rosemary Penwarden, [a 64 year old] climate activist in New Zealand, faces more than 10 years in jall for a fake letter canceling an oil conference.

Three years later, after a trial in the Dunedin District Court, Penwarden was found guilty on Wednesday of two charges of creating and using a forged document.

“It was a surprise,” she said. “I’m reminded of the topsy-turvy world we’re in. It should not be the grandmothers on trial, it should be the oil industry, it should be those people who are making massive profits off the destruction of all of our futures.”

France will deploy 40,000 police officers to quell violence that followed deadly police shooting (apnews.com)
 

Based on an initial investigation, Prache said, he concluded that "the conditions for the legal use of the weapon were not met.”

Three persons were in the car when police tried to stop it Tuesday, the prosecutor said. Nahel managed to avoid a traffic stop by running a red light. He was later got stuck in a traffic jam.

Both officers involved said they drew their guns to prevent him from starting the car again.

The officer who fired a single shot said he wanted to prevent the car from leaving and because he feared someone may be hit by the car, including himself or his colleague, according to Prache.

Both officers said they felt “threatened” by seeing the car drive off, he added.

Why do so many Black women die in pregnancy? One reason: Doctors don't take them seriously (apnews.com)
 

The nation’s health disparities have had a tragic impact: Over the past two decades, the higher mortality rate among Black Americans resulted in 1.6 million excess deaths compared to white Americans. That higher mortality rate resulted in a cumulative loss of more than 80 million years of life due to people dying young and billions of dollars in health care and lost opportunity.

For decades, frustrated birth advocates and medical professionals have tried to sound an alarm about the ways medicine has failed Black women. Historians trace that maltreatment to racist medical practices that Black people endured amid and after slavery.

The disparities between Black and white babies is stark: The infant mortality rate in 2021 for white mothers was 5.8, while the infant mortality rate for Black mothers was 12.1, an increase from 10.9 from the prior year.

Black babies account for just 29% of births in Alabama, yet nearly 47% of infant deaths.

A 2020 report by the Alabama Maternal Mortality Review Committee found that more than 55% of 80 pregnancy-related deaths that they reviewed in 2016 and 2017 could have been prevented.
