Cash's World Server

Did I say I would start the server soon?
Define 'soon'
A long string of problems being solved one by one :/
I finally got the VM to boot! Took an hour or more to accomplish that.

nuttcp, mpstat, and http://fasterdata.es.net/network-tuning/ might be helpful

max_lags = 28.3

You are searching for some bad adventure, why do you need redis? Your max_lag was acceptable, network was the only problem. Does your CPU even support hardware virtualization?

The MT server was running slow in a Linux VM under a Windows 10 host. The 320GB SATA2 7,200 rpm HDD used to hold the VM was constantly writing to disk at ~40MBps and seemed to be a bottleneck.

I wanted to see if Redis would speed things up. It seems to have done so. The HDD is idle for about 3 minutes. Then Redis takes about 2 minutes writing its db file to disk.

For the Linux VM, I have set a few parameters in /proc/sys/net/ that Redis suggested to help speed up its network usage. Only one setting is permanent. I don't know how to set the others permanently under Fedora with its systemd garbage so I have to type them in each time a restart the VM. I do not know how to do the same for the Windows host though. I made one change earlier today that took my computer offline for about an hour before I reversed it. Oops.

I am weakly considering moving Redis to another VM and use an internal network interface. But it is already using the loopback interface so I don't know if doing so would help. 16GB ram might not be enough for 2 VMs either.

I have a Intel i7-3820 quad-core cpu with 16GB DDR3 ram that is not very busy and does support hardware virtualization.

The server seems to not have much lag now. It actually seems faster per the lag number (79) in the server list. Though I do see large lag sometimes but not for long. I don't know the cause of it. Maybe I should do some playing in the world so I can see when it lags and how bad.

I see two problems to solve:
1 - Sometimes the server continues to run but nothing happens. Players can not log in. Redis is idle but the MT server is using up all the cpu time. I have to restart the MT server to get it going again. I am not sure of how often this happens. Twice already.
2 - The server pauses whenever a player times out or joins. Is the server single threaded? I hope the developers do something about that. But in a way so that new players do not get killed before fully joined. This has been an ongoing problem.

Too bad I can't use a unix socket for the MT server and redis comm link. That might speed things up much more.

I will switch back to using Linux as the host soon and install a 'mod' that has been ready for about a week now. Once issues with that has been resolved, I will start working on fixing and adding things to the world.

Server is currently crashing a lot. Not sure the reason yet.

[PurpleOne]

Aaaaand the server is down :/

[Vlad_plays_minetest]

Things seem to be back to normal now

67..... He has his fits sometimes, but most times he's cool.

[Vlad_plays_minetest]

He is sometimes but when he has his fits he over does it.once he said his real life girl friend raped him and now he says bullies are gonna kill him.other than that he always bothers Klitzing870 cuz she left him

And here's me and my bro taking pics XD

Strange.
Is that what you see when you look at an autocrafter or when you open one?
Is there a prot block nearby?

The code for the autocrafter does not have an image of a prot block as part of the autocrafter's image.
Maybe try another MT client? You can try the official MT client at www.minetest.net/downloads

Nice portrait of you and your brother :)

As for Salex, if needed, I can ban him via the Linux ip command. Then my server will never even see any network traffic from him.

This is getting too much for me. It never stops and im standing completely still. Been like this for 3 days. Was hopping it would go away on it's own and it hasn't.

I don't know if this will help you or not, but some of my problems have been fixed with a simple "/kill" :) Just try and see.

[843jdc]

/kill ?

I was having problems just now working with the virtual machine. It was capturing my mouse. It did accept a Ctrl-C though :/

Since the server is down, I'm going to take a bit to delete some of the 77,000+ player files.

I won't do a thorough delete. Just enough to bring the number of files down a bit. Server should be back up in about 30 minutes.

[PurpleOne]

Did the server get shut down? Or was I kicked?

[PurpleOne]

Ignore that post ^

[843jdc]

I was getting no response from the server. So I tried a Ctrl-C to shut it down. Though I did not intend to shut it down. Oops.

[843jdc]

I am searching for player files that have 'expensive' stuff in inventory like steel, gold, diamonds, etc. Those player files will be saved. Everyone else will have their player files deleted and will reappear at spawn the next time they log in.
That is a lot of files to scan. haha xD

[PurpleOne]

So even the pros owned by them will still be present? Or will those get removed when the player names get whipped?

[843jdc]

Players files contain information about the player's location, direction looking in, and what is in inventory. Players passwords and properties will not be affected.

Almost finished now. I am doing this quick and dirty.

[843jdc]

5,892 player files saved. Goodbye to 71,366 player files.

Restarting server

[843jdc]

Server is up

[BBmine]

Was my player file saved? (Tho I'm trying to remember if I had more than wood junk on me :P)

[843jdc]

IDK

[Wraz]

I hate your virtual machine.
Doors open after 8 seconds.
Awww

great, moving items in inventory ~ 20 second
