Utility: Linux Admining

[Lihaässä]

Thanks vfb. I'm almost there, you are correct, there is no need for "-g" command. At the moment the script looks like below. The game starts but when trying to play a turn it just closes the gamewindow. It also says "send, broken pipe"

#!/bin/bash
# Tällä käynnistellään dqotonen domi hostaukset
# jee


GAME="rivers"
MAP="Rivers.map"
ERA=3
MOD="CBcomplete_1.6.dm"
BUP={rsync -a /home/dom/dominions3/savedgames/* /backup/}
AID="0"
START=5

PORT="2222"
DOM="/home/dom/dominions3/dom3"

$DOM -S -T --port $PORT $GAME --era $ERA --mapfile $MAP \
-q --indepstr 9 --uploadmaxp $START --diffai $AID --enablemod $MOD --postexec $BUP

[vfb]

Did you try this?

BUP="rsync -a /home/dom/dominions3/savedgames/* /backup/"

[Lihaässä]

Yeah, after that it asks for the game name and this happens.

[Gandalf Parker]

I generally use pre.sh and post.sh

Also I think you want --preexec rather than --postexec

Once the game hosts, saving a copy is not much use since it will match the game itself. Players will complain about the hosting results in which case you want to be able to return to the files prior to hosting.

By the way, I find it more useful in many many ways to do
nice zip -9 game.zip * -x *game.zip -x z*
and then attach it to a email going to an address off-system.
That provides:
A) backup
B) dated multiple backups allowing restore to multiple points
C) security in case of system crashes or hard drive failures
D) ease of forwarding the latest games files to someone else in case they volunteer to pick up running the game for some reason

Thanks for the answers and help! I'm still struggling with the script, but will make it work somehow. Fortunately backing up files isn't mandatory. Happiness is

[Lihaässä]

Done! Thanks to my awesome anonymous friend and you guys my script is ready for hosting. Feel free to copy if you need such a simple script.

I see a couple of problems here:

• You copy all games every time any game hosts. Which clobbers the backups of all games other than the one about to be hosted.
• You only maintain a backup of the latest turn. This will cause trouble when the game manages to **** itself up so that it crashes at next hosting, because by the time you notice it crashing, you've clobbered the backup from before it broke.
  (Yes, this can happen. Guess what made me think it was a good thing I was already backing up all truns?)

If you look approximately halfway up the thread, I've posted a backup script that has neither of those particular issues.

[Lihaässä]

You are correct, the script is simple but easily altered to backup only one game.. in this case /home/dom/dominions3/backup/Rivers/
I hope that the game won't crash and use this one.

Your script was too much for me and I didn't understand it. Thanks for your input. I will look it again when I find the time.

Hi there, I see that people are sharing their Linux server scripts here. In case it helps: somebody contacted me about the Linux server scripts that I use for administrating my Dom3 games around June, here's what I sent back. Configuration is done by editing the GAME and PORT variables inside the scripts, and by setting the player's email addresses for email notification in the post-exec script.

Main script "MyGame.sh", this is being started in a "screen" session

PHP Code:

#!/bin/bash

GAME=MyGame
PORT=1337
DIR="/home/dom3/dominions3/savedgames/"$GAME

mkdir $DIR &>/dev/null

# reset timer for the stats.php script
if [ -e $DIR/ftherlnd ]
then
  touch $DIR/ftherlnd
fi

~/Dom3/dom3 $GAME --port $PORT -STddd --scoredump --renaming \
--era 2 --mapfile 'MyGameMap.map' \
-q \
--masterpass MyGamePassword \
--noclientstart --uploadmaxp 7 \
--hofsize 15 --indepstr 6 --renaming \
--preexec /home/dom3/dominions3/${GAME}_pre.sh --postexec /home/dom3/dominions3/${GAME}_post.sh \
>>$DIR/$GAME.log 2>>$DIR/$GAME.err 


Pre-hosting script "MyGame_pre.sh", this is being started before hosting and makes a backup of the game/turn data

PHP Code:

#!/bin/bash

GAME=MyGame
PORT=1337
DIR="/home/dom3/dominions3/savedgames/$GAME"

# make backups
pushd "$DIR/.."
tar czf "/home/dom3/dominions3/backups/"$GAME-$(date +%s)-pre.tgz $GAME
popd

# blank the log files after backup
cp /dev/null $DIR/$GAME.log
cp /dev/null $DIR/$GAME.err 


Post-hosting script "MyGame_post.sh", this is being started after hosting and makes a backup of the game/turn data, updates my online game statistics and sends a notification to the other players

PHP Code:

#!/bin/bash

GAME=MyGame
PORT=1337
GAMElow=`echo $GAME | tr "[:upper:]" "[:lower:]"`
DIR="/home/dom3/dominions3/savedgames/$GAME"
SENDMAIL="sendmail -t "

# make backups & save scores
pushd "$DIR/.."
tar czf "/home/dom3/dominions3/backups/"$GAME-$(date +%s)-post.tgz $GAME
php /home/dom3/dominions3/backups/scores2mysql.php "$GAME/scores.html"
popd

# blank the log files after backup
cp /dev/null $DIR/$GAME.log
cp /dev/null $DIR/$GAME.err

# email notify players that have asked to be told of turns
Player1=player1@email.com
Player2=player2@email.com
Player3=player3@email.com
Player4=player4@email.com
Player5=player5@email.com
Player6=player6@email.com

# the actual sendmail needs a single dot "." in the last line at the end of the message, nbsmtp does not
$SENDMAIL <<EOF
From: '$GAME' Dom3 game server <$GAMElow@my-own.email>
Bcc: $Player1, $Player2, $Player3, $Player4, $Player5, $Player6, $GAMElow@my-own.email
Subject: $GAME has hosted!

The Dominions 3 game you are playing in ($GAME) has processed a new turn.
Please connect to server dom3.servegame.com port $PORT to play your next turn!

Here is the turn status page for the game: http://dom3.servegame.com/stats/stats.php?game=$GAME

I am not hosting games right now and my Dom3 activities are in hiatus, but maybe these shell scripts are an inspiration for somebody else. I needed to use PHP syntax highlighting environment here because the CODE environment doesn't display the shell code correctly. (double <)

[Gandalf Parker]

More script examples are always helpful. I also have the old Dom2 pbem BBS using php and sql. I dont remember if Ive seen Llamabeasts scripts since about mid-way thru the discussions on creating his server. Those would be worthy to look at also.

One thing Id add would be the mail support. Ive played abit with
mail, sendmail, mutt, pine, postfix, mpack/munpack, and biabam. If I remember right I got them all to work. But now for receiving player files I use munpack, and for sending turn attachments I prefer biabam. I also like to attach the backup files to an outgoing email just to have them off-system
