No Comments on How to run WordPress Cron from CLI

I prefer to run cronjobs from the CLI instead of a web call.
This mostly due the memory and timeout limits that you can run into when you do use a web based cronjob.

To configure this you first have to disable the web cron within WordPress.

define('DISABLE_WP_CRON', true);

1	define('DISABLE_WP_CRON', true);

Then you can add the following cronjob to make it run every 10 minutes.

# /etc/crontab
*/10 * * * * username /usr/local/bin/php /path/to/wp-cron.php

# user cronjob
*/10 * * * * /usr/local/bin/php /path/to/wp-cron.php

# /etc/crontab

*/10 * * * * username /usr/local/bin/php /path/to/wp-cron.php

# user cronjob

*/10 * * * * /usr/local/bin/php /path/to/wp-cron.php

Optionally disable the output

# /etc/crontab
*/10 * * * * username /usr/local/bin/php /path/to/wp-cron.php > /dev/null

# user cronjob
*/10 * * * * /usr/local/bin/php /path/to/wp-cron.php > /dev/null

# /etc/crontab

*/10 * * * * username /usr/local/bin/php /path/to/wp-cron.php > /dev/null

# user cronjob

*/10 * * * * /usr/local/bin/php /path/to/wp-cron.php > /dev/null

Now you are sure that the job runs and finishes without it depending on how much visitors you have or timeouts that can occur.

No Comments on Left Hand adapter to play piano without a full hand

I stumbled upon this wonderful 3D design which is actually printable.

It is an attachment to be clamped on the arm so you can play the piano.
It allows you to arpeggio one octave in the major and minor scales on all of the white and black keys!

A wonderful design if you’d ask me. I think a lot of people would like to have solutions like this.

Now, in case you are not able to print it your self. You can order prints on Thingyverse or if you live close near me (The Netherlands) I can print it for you for just the material and shipping cost.

Be sure to visit Mat Bowtell his Thingiverse page.

You can find the design and the arm attachment design in the links below.

Download STL files here.

To keep the strength and use less plastic I changed the fill to honeycomb and added two bars near the edges to prevent bending.

Made this as part of my LACK modification for “Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table – Prusa Research” https://www.thingiverse.com/thing:2864118

Wine and beer rack from pallet wood

No Comments on Wine and beer rack from pallet wood

Everybody likes a drink one in a while, but how nice would it be to have a place where to have your drinks including glasses stored and be able to see what you have in stock.

A nice way, a rack made out of pallet wood.

Requirements to create this:

Drill 3mm
Drilling and screwing machine
Screws
Time
Hammer
Two pallets (preferable euro pallets, EPAL)

First you have to get some pallets and remove the bottom side.

Then use the bottom side to create the shelves which will hold your bottles and glasses.

Cut out four holes for the bottles and eight U shape holes for the glasses.

In 45 degree, cut two of these holders, they are for the back of the pallet and for the wall.
This way of hanging your pallet will make it hang flat to the wall.

Screw one half to the pallet back at the top and use a bit of wood glue to make a more robust construction.

Drill holes in the wall and screw the opposite side to the wall and hang your pallet.

Top view of the pallet.

Now fill up your pallet with bottles and glasses, and light a candle to make it nice and cosy.

You are all set, now grab your self a wine or a beer from your own created pallet rack.

How to train SpamAssassin to improve spam detection accuracy on DirectAdmin

Post author By mariusvw

1 Comment on How to train SpamAssassin to improve spam detection accuracy on DirectAdmin

Spam, one of the most irritating things when using mail.

In this article I will explain how to configure SpamAssassin to filter spam and to learn from messages you mark as Spam.
Based on assumption messages remaining in your INBOX will be learned as Ham (not spam).

When a message in your INBOX is Spam, you only have to move it to the Spam folder to let SpamAssassin learn it as spam.

SpamAssassin Setup

First of all, lets configure SpamAssassin correctly to start filtering Spam.

Go to the Spamassassin Setup page and configure the settings like shown in the below screenshot.

Where do you want the spam to go?

Send the spam to the user’s spam folder.

What score threshold do you wish to use?

Low Threshold (5.0)

Would you like to delete high scoring spam?

Yes, block all spam scoring higher than: 10 (1-50, no decimals)

Do you wish to rewrite the subject of a spam email?

No, leave the subject unchanged.

How should the spam be delivered?

Don’t use attachments (dangerous).

Second is to install a script which will learn what is Spam or Ham to SpamAssassin.

This can be done on two ways, one script that runs as root and starts sa-learn for every mailbox under the user which owns the mailbox or a script that runs as an unprivileged user.

As extra feature it will remove spam messages from INBOX.spam who are older than one month.

Learn as unprivileged user

This will explain how to run the script as an unprivileged user, you have to place this script in ~/scripts/sa-learn.sh and create a cronjob to call it once in a while. The interval I choose is 5 minutes. I don’t have many mailboxes so this is fine for me.

#!/bin/sh
#
# Learning script for SpamAssassin on DirectAdmin
#
# Will learn what is Spam or Ham and delete Spam older than 30 days.
# Runs as unprivileged user and scans only domains owned by that user.

Don’t forget to make the script executable:

Then add a cronjob to your account via the DirectAdmin control panel.

MAILTO=your@mail.address
# Learn SpamAssassin something every 5 minutes
*/5 * * * * $HOME/scripts/sa-learn.sh

MAILTO=your@mail.address

# Learn SpamAssassin something every 5 minutes

*/5 * * * * $HOME/scripts/sa-learn.sh

Optionally instead of mailing the output you can mute the output.

# Learn SpamAssassin something every 5 minutes
*/5 * * * * $HOME/scripts/sa-learn.sh >/dev/null

1 2	# Learn SpamAssassin something every 5 minutes /5 * * * $HOME/scripts/sa-learn.sh >/dev/null

Or mute all output including errors

*/5 * * * * $HOME/scripts/sa-learn.sh >/dev/null 2>&1

1 2	# Learn SpamAssassin something every 5 minutes /5 * * * $HOME/scripts/sa-learn.sh >/dev/null 2>&1

Learn as root user

This will explain how to run the script as root, you have to place this script in /root/scripts/sa-learn.sh and create a cronjob to call it once in a while. The interval I choose is 15 minutes. This is higher than the unprivileged-user script due you have to look through more mailboxes.

No Comments on How to configure a automatically native IPv6 connection on FreeBSD

First you need to install a DHCP client

cd /usr/ports/net/dhcp6
make install clean

1 2	cd /usr/ports/net/dhcp6 make install clean

Setup config for dhcp6c

cp /usr/local/etc/dhcp6c.conf.sample /usr/local/etc/dhcp6c.conf
vi /usr/local/etc/dhcp6c.conf

1 2	cp /usr/local/etc/dhcp6c.conf.sample /usr/local/etc/dhcp6c.conf vi /usr/local/etc/dhcp6c.conf

Add the following

interface em0 {
    send ia-pd 0;
};

id-assoc pd {
    prefix-interface em0 {
        sla-id 1;
    };
};

interface em0 {

send ia-pd 0;

};

id-assoc pd {

prefix-interface em0 {

sla-id 1;

};

Add the following to /etc/rc.conf

ipv6_enable="YES"
ipv6_network_interfaces="em0"
ipv6_defaultrouter="fe80::%em0"
dhcp6c_enable="YES"
dhcp6c_interfaces="em0"

ipv6_enable="YES"

ipv6_network_interfaces="em0"

ipv6_defaultrouter="fe80::%em0"

dhcp6c_enable="YES"

dhcp6c_interfaces="em0"

Run the IPv6 startup script.

/etc/rc.d/network_ipv6 restart

1	/etc/rc.d/network_ipv6 restart

Now startup the client

/usr/local/etc/rc.d/dhcp6c start

1	/usr/local/etc/rc.d/dhcp6c start

To test the connection you should be able to ping XS4ALL.

ping6 xs4all.nl

How to add bots to your Urban Terror server via RCON

Post author By mariusvw
Post date June 19, 2011
No Comments on How to add bots to your Urban Terror server via RCON

First of all you need to configure your server first! For more info about that check here.

Now you should have your server all up and running, next thing is having control over your bots.

bot configuration

First enable the use of bots

/rcon bot_enable 1
/rcon reload

1 2	/rcon bot_enable 1 /rcon reload

Next, lets add bots.

/rcon addbot  [level] [team] [ping] [nick]

1	/rcon addbot [level] [team] [ping] [nick]

addbot arguments

type
Define the name of the bot type here, chose one from the list below.
level
Define a number from 1 to 5 here to set how good the bots will try to hunt you down!
team
Define the color name Red or Blue to set the team this bot belongs to.
ping
Define the average ping time the bot will have, if you define this to a low value the bots will respond fast, I recommend setting this to 40 on a local LAN and 75 on a WAN connection.
nick
Define the nickname of the bot, I usually give a simple name like Bot1, Bot2, Bot3, etc…

addbot examples

/rcon addbot Chicken Blue 75 Bot1
/rcon addbot Cockroach Blue 75 Bot2
/rcon addbot Mantis Blue 75 Bot3

/rcon addbot Chicken Blue 75 Bot1

/rcon addbot Cockroach Blue 75 Bot2

/rcon addbot Mantis Blue 75 Bot3

In case you want to get rid of one or all bots, simply kick them!

/rcon kick [nickname]
/rcon kick allbots

1 2	/rcon kick [nickname] /rcon kick allbots

Here is a simple Bash example that you could use to add or remove bots:

#!/bin/bash

# Add bot
echo -e "xFFxFFxFFxFFaddbot Chicken Blue 75 BOTNAMEn" | /usr/bin/nc -D -4 -d -n -u 127.0.0.1 27960

# Remove bot
echo -e "xFFxFFxFFxFFkick BOTNAMEn" | /usr/bin/nc -D -4 -d -n -u 127.0.0.1 27960

#!/bin/bash

# Add bot

echo -e "xFFxFFxFFxFFaddbot Chicken Blue 75 BOTNAMEn" | /usr/bin/nc -D -4 -d -n -u 127.0.0.1 27960

# Remove bot

echo -e "xFFxFFxFFxFFkick BOTNAMEn" | /usr/bin/nc -D -4 -d -n -u 127.0.0.1 27960

How to install an Urban Terror server with bots on FreeBSD

Post author By mariusvw
Post date June 19, 2011
1 Comment on How to install an Urban Terror server with bots on FreeBSD

This will install an Urban Terror server running under the user urban with 4 bots enabled on the server.

First of all we install the binaries, I prefer installing them from the ports, in case you don’t have root access you might want to manually download from https://www.urbanterror.info/. The configuration is quite the same so you should be able to install on your own.

For the port install use:

Lets get some coffee, cause this installation might take a while… The installation requires downloading UrbanTerror411.zip from one of the mirrors which is around 1GB in size 🙂

After installing you need to add a user to run the server.

pw user add urban -m

1	pw user add urban -m

I don’t set a password for this account simply because I mostly su into it 😉 So…

su - urban

1	su - urban

First create the required directories

mkdir -p .ioUrbanTerror/q3ut4
cd .ioUrbanTerror/q3ut4

1 2	mkdir -p .ioUrbanTerror/q3ut4 cd .ioUrbanTerror/q3ut4

In this directory you need to add the configuration files: server.cfg / mapcycle.txt / bots.cfg

server.cfg

sets "Admin" "Marius van Witzenburg"
sets "Email" "marius@"
set rconpassword "This_Is_Your_RCON_Password"
set g_gametype "0"
set sv_hostname "Fire in the hole!"
set g_respawndelay "1"
set bot_enable "1"
set g_teamautojoin "1"
set g_maxteamkills "5"
set g_respawnprotection "3"

// (restart/map/nextmap/cyclemap)
set g_allowVote "536870926"

set g_log ""
set g_logroll "0"

set fraglimit "50"
set timelimit "15"

// Startup map
map ut4_turnpike

// Add bots
exec bots.cfg

sets "Admin" "Marius van Witzenburg"

sets "Email" "marius@"

set rconpassword "This_Is_Your_RCON_Password"

set g_gametype "0"

set sv_hostname "Fire in the hole!"

set g_respawndelay "1"

set bot_enable "1"

set g_teamautojoin "1"

set g_maxteamkills "5"

set g_respawnprotection "3"

// (restart/map/nextmap/cyclemap)

set g_allowVote "536870926"

set g_log ""

set g_logroll "0"

set fraglimit "50"

set timelimit "15"

// Startup map

map ut4_turnpike

// Add bots

exec bots.cfg

In case you want to change this configuration, check out: http://www.urbanterror.info/docs/180-/

mapcycle.txt

ut4_turnpike
ut4_abbey
ut4_prague
ut4_mandolin
ut4_algiers
ut4_austria
ut4_sanc

ut4_thingley

ut4_turnpike

ut4_abbey

ut4_prague

ut4_mandolin

ut4_algiers

ut4_austria

ut4_sanc

ut4_thingley

I limited the map list to the maps that work fine with bots.

bots.cfg

kick allbots
addbot boa 4 blue 25 "Bot 1"
addbot chicken 4 blue 25 "Bot 2"
addbot cockroach 4 blue 25 "Bot 3"
addbot goose 5 blue 25 "Bot 4"

kick allbots

addbot boa 4 blue 25 "Bot 1"

addbot chicken 4 blue 25 "Bot 2"

addbot cockroach 4 blue 25 "Bot 3"

addbot goose 5 blue 25 "Bot 4"

You can start the server by manual but I would advice you do run the server with this script in tmux or in GNU Screen.

start.sh

#!/bin/bash

# Dedicated
# 1 don't report
# 2 report to master servers

myExit() {
	kill $
	exit $?
}

trap myExit SIGINT

while true
do
	/usr/local/bin/ioUrTded 
		+set fs_game q3ut4 
		+set dedicated 1 
		+set net_ip 192.168.1.5 
		+set net_port 27960 
		+set com_hunkmegs 128 
		+exec server.cfg

	echo "server crashed on `date`" &gt; /usr/home/urban/last_crash.txt
done

#!/bin/bash

# Dedicated

# 1 don't report

# 2 report to master servers

myExit() {

kill $

exit $?

}

trap myExit SIGINT

while true

/usr/local/bin/ioUrTded

+set fs_game q3ut4

+set dedicated 1

+set net_ip 192.168.1.5

+set net_port 27960

+set com_hunkmegs 128

+exec server.cfg

echo "server crashed on `date`" > /usr/home/urban/last_crash.txt

done

Run it by doing

chmod 700 start.sh
./start.sh

1 2	chmod 700 start.sh ./start.sh

In case you want this server to be reachable for the public, don’t forget to set dedicated to 2.

Good luck! If you have any questions, let me know!

How to configure a IPv6 gateway for XS4ALL on FreeBSD

No Comments on How to configure a IPv6 gateway for XS4ALL on FreeBSD

You might first need these two manuals.

How to use a PPPoE or PPPoA connection of XS4ALL on FreeBSD

How to configure IPv6 DHCP client for XS4ALL on FreeBSD

Configuring your server as a router is quite simple.

First edit /etc/rc.conf and add the following

ipv6_ifconfig_em0="2001:980:5E29::1 prefixlen 64"
ipv6_defaultrouter="-interface tun0"
ipv6_gateway_enable="YES"
rtadvd_enable="YES"
rtadvd_interfaces="em0"

ipv6_ifconfig_em0="2001:980:5E29::1 prefixlen 64"

ipv6_defaultrouter="-interface tun0"

ipv6_gateway_enable="YES"

rtadvd_enable="YES"

rtadvd_interfaces="em0"

This configures IPv6 for your interface and tells it to function as a gateway.

Now setup the config for rtadvd so it will give out the right IP range. Edit /etc/rtadvd.conf

em0: 
:addr="2001:980:5E29::":prefixlen#64:

1 2	em0: :addr="2001:980:5E29::":prefixlen#64:

Now fire up a client connected to the LAN side on em0 and visit the following page to check if you are using IPv6:

https://www.xs4all.nl/klant/veiligheid/mijnip

Another useful page with information how to configure IPv6 on your server is in the FreeBSD handbook.
