Renewed your SSL certificate and importing it into IIS 7

Copy your certificate you receive and save it on your windows machine.

Now open the MMC window ( start -> run -> mmc) and go to file -> add/remove snap-in, choose certificates from this list. Click on Add and choose Computer account in the list.

Click Next and select Local computer, and click Finish and then Ok.

Go to Certificates (local computer) -> personal -> certificates.

In the certificates box, right mouse click -> all tasks -> import.

Choose your certificate file and finish the import process.

Now you’ll see that the certificate misses its private key.

Double click on your certificate, go to the details tab and choose thumbprint.

Copy this and open a command prompt:

certutils –repairstory my “thumbprint” (of iets gelijk dat)

When you refresh your certificates you should see that the key has an extra symbol attached, and your certificate should be valid again.

Exim blacklist on directadmin

One of the interesting things in exim is blacklisting, unfortunately this is not enabled by default.

To enable blacklisting you need to execute these 3 commands as root on your server:

cd /etc/virtual
rm use_rbl_domains
ln -s domains use_rbl_domains

Using a huawei E1750 as a sms gateway

First we need to install some debian packages we need:

apt-get install build-essential libhid-dev bzip2 tcl8.5-dev

Because the huawei E1750 has a card reader integrated we need to disable this to use the modem, to do this we need to download Usb-modeswitch.

cd /usr/src
wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-1.1.4.tar.bz2
wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20100826.tar.bz2
tar xvjf usb-modeswitch-1.1.4.tar.bz2
tar xvjf usb-modeswitch-data-20100826.tar.bz2
cd usb-modeswitch-1.1.4

make install

cd usb-modeswitch-data-20100826
make install
cp 40-usb_modeswitch.rules /etc/udev/rules.d/
udevadm control –reload_rules

Edit the file /etc/usb_modeswitch.conf en paste this below the other options.

# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# This file is evaluated by the wrapper script “usb_modeswitch_dispatcher”
# in /usr/sbin
# To enable an option, set it to “1”, “yes” or “true” (case doesn’t matter)
# Everything else counts as “disable”

# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0

# Enable logging (results in a extensive report file in /var/log, named
# “usb_modeswitch_

EnableLogging=0

########################################################
;DefaultVendor= 0x12d1
;DefaultProduct= 0x1446

MessageEndpoint = 0x01

########################################################

Lets execute usb_modeswitch to disable the card reader

usb_modeswitch -v 0x12d1 -p 0x1446 -H -s 5 -c /etc/usb_modeswitch.conf

You should get some output like this:

Mode switch succeeded. Bye.

The part where it says: “Mode switch succeeded. Bye.” is important, if it doesn’t say succeeded you’ll have to look for the right vendor and product id. You can find this by using lsusb.

I’ll assume it said succeeded and we are going to install everything we need to use gnokii, as i’m a great fan of MySQL i want to put all my data in mysql so we need a mysql server and the mysql version of gnokii.

apt-get install gnokii-smsd-mysql mysql-server-5.0 gnokii-cli

Setup the mysql database, create a database + user.

echo “create database smsd” | mysql -u root -p

echo “grant all on smsd.* to gnokii@’localhost’ identified by ‘password'” | mysql -u root -p

Import the gnokii sql file

mysql smsd < /usr/share/doc/gnokii-smsd-mysql/sms.tables.mysql.sql

Now our database is ready for use, the next thing we need to do is configure our gnokii.

edit /etc/gnokiirc

(this is what mine looks like)

# This is a sample ~/.gnokiirc file. Copy it into your
# home directory and name it .gnokiirc.
# See http://wiki.gnokii.org/index.php/Config for working examples.
#

[global]
port = /dev/ttyUSB0
model = AT-HW
initlength = default
connection = serial
use_locking = yes
serial_baudrate = 9600
handshake = hardware
smsc_timeout = 30

[xgnokii]
allow_breakage = 0

[gnokiid]
bindir = /usr/sbin/

[connect_script]
TELEPHONE = 12345678
[disconnect_script]

[logging]
debug = off
rlpdebug = off
xdebug = off

We should be able to see some data of our modem, lets see if gnokii can identify our huawei:

gnokii –identify

GNOKII Version 0.6.26
Couldn’t read /root/.gnokiirc config file.
Couldn’t read /root/.gnokiirc config file.
IMEI : 351910046446428
Manufacturer : huawei
Model : E1750
Product name : E1750
Revision : 11.126.00.00.00

If you see this everything should work fine.

Now we can test if we can send a sms manually.

echo “testing if we can send sms” | gnokii –sendsms +32477……

A couple of seconds later you should receive the sms on your phone.

Now lets start the smsd daemon.

/usr/sbin/smsd -u gnokii -p password -d smsd -m mysql -f /var/log/smsd/smsd.log &

And fill in some data in our outbox.

mysql smsd
insert into outbox(number,text,dreport) values (‘+32477……’,’testing if we can send from gnokii-smsd’,1);

You should receive a text message shortly

Faster way to install directadmin

Sometimes I need to install directadmin on our vds servers, as we don’t use templates for this I was looking for an easy and faster way to install new servers.
A couple of weeks ago I found the solution and i thought I’d share it.

apt-get install gcc g++ debianutils binutils make autoconf automake vim pwgen
wget http://www.directadmin.com/setup.sh
chmod +x setup.sh
mkdir -p /usr/local/directadmin/custombuild
wget http://bugoff.be/wp-content/uploads/2010/04/options.conf -O /usr/local/directadmin/custombuild/options.conf
echo 1.2 > /root/.custombuild
./setup.sh <User ID> <License id> <servername> <eth>

This will install your directadmin server with my options.conf file, correct the options to what you want. I always install my servers using php-cgi.
