Setting Courierpassd

download courierpassd-1.1.2.tar.gz

# tar -zxvf courierpassd-1.1.2.tar.gz

# cd courierpassd-1.1.2

# ./configure

# make && make install

OK. Courierpassd is installed now. Next, we are going to configure Xinetd/Inetd to run courierpassd.

If your server uses Xinetd, here’s how you integrate Courierpassd into it:

# cd /etc/xinetd.d

Here we create the xinetd script for courierpassd…

# vi courierpassd

Add the following to the file you are creating:

service courierpassd
{
port = 106
socket_type = stream
protocol = tcp
user = root
server = /usr/local/sbin/courierpassd
server_args = -s imap
wait = no
only_from = 127.0.0.1
instances = 4
}

Note: You may want to add additional IP’s to the “only_from” setting above, depending on your needs.

Save and exit.

OR

If your server uses Inetd, here’s how integrate Courierpassd into it:

# vi /etc/inetd.conf

Add the following line:

courierpassd stream tcp nowait root /usr/local/sbin/courierpassd -s imap

Save and exit.

Now let’s add the Courierpassd service to the system’s services file:

# vi /etc/services

Append to following line to the /etc/services file:

courierpassd 106/tcp #for /etc/xinetd.d/courierpassd

Now lets restart xinetd OR inetd (whichever you are using):

# /etc/init.d/xinetd restart

OR

# /etc/init.d/openbsd-inetd restart

Note: The daemon names on your system might be named differently. On Sarge and perhaps Ubuntu systems, the inetd command minght need to be /etc/init.d/inetd restart

Now let’s test Courierpassd by trying the reset the password for a mail account. Here’s what a successfull test should look like (change the bold items to your own information):

root@syngin:/# telnet localhost 106
Trying 127.0.0.1…
