This guide assumes you have CentOS 5.5 installed, a  working Postfix configuration and that you would like to sign mail for more than one domain. It was carried out with the following software versions:

• Postfix 2.3.3
• OpenDKIM 2.0.4
• Sendmail (sources) 8.13.8
• OpenSSL 0.9.8e

Important links:

• OpenDKIM
• Sendmail DKIM tools

Install other necessary software

# yum install sendmail-devel
# yum install openssl-devel

If you want to know exactly where the files belonging to a package are (OpenDKIM’s compiler should find them automatically):

# rpm -ql sendmail-devel
/usr/include/libmilter
/usr/include/libmilter/mfapi.h
/usr/include/libmilter/mfdef.h
/usr/lib/libmilter.a
/usr/lib/libsm.a
/usr/lib/libsmutil.a

Installing OpenDKIM

Download then extract OpenDKIM. Change to the extracted direcotry and run configure, make and then, as root, make install

$ tar -xzvf opendkim-2.0.4.tar.gz
$ cd opendkim
$./configure
$ make
$ su -
# make install

You will need the following information to complete this guide:

• The email address of your IMAP enabled email account.
• The address of the server you connect to to retrieve your emails (incoming mail server).
• The address of the server you connect to to send emails (outgoing mail server or SMTP server) and whether it requires authentication.
• The user name for your IMAP email account (this is often the same as your email address or the part before the ‘@’ symbol).
• The password for your email account.
• The ports that your provider’s incoming and outgoing server uses and whether they use secure password authentication (SPA) and SSL/TLS

Setting up Outlook 2003 with your Calmblue email account?
Check our Calmblue email page for the information.

If this is the first time you have run Outlook 2003 you will be presented with the Accounts wizard so you can skip this first bit…

Go to the menu ‘Tools’ and click on ‘E-mail Accounts…’ if you cannot see ‘Email Accounts…’ click the two blue arrows at the bottom of the menu to reveal all the options.

You will be presented with the Accounts wizard, click on ‘Add a new e-mail account’ then click ‘Next’

Now select IMAP and then click ‘Next’ again

Now click on ‘More settings …’. You will be presented with another window that has four tabs: General, Outgoing server, connection and Advanced. In the ‘General’ tab you can enter your organisation name or ‘private’ if you like, then your email address again, although this is not essential.

Change to the ‘Outgoing server’ tab, this is where we set up how you send emails. Tick ‘My outgoing server (SMTP) requires authentication’ if yours does – most do. Then leave ticked ‘Use same settings as my incoming mail server’ as this will normally be the case. If your outgoing server requires different login details then you will need to tick ‘Log on using’ and enter them in there.

Finally, click on the ‘Advanced’ tab to select the ports Outlook should connect to you sever on and whether the server uses SSL.

• Under ‘Incoming server (IMAP), tick ‘This server requires an encrypted connection (SSL)’ and the port should change to 993. This will be correct for most secure servers.

• Under ‘Outgoing server (SMTP) tick ‘This server requires an encrypted connection (SSL)’ then manually change the port to 465. This will be correct for most secure servers*. For example:

*When using Outlook 2002 (XP) with a server that supports TLS you should leave the outgoing (SMTP) server port as 25.

After clicking ‘OK’ you will be dropped back at the ‘Email accounts wizard’ where you can click ‘Next’ followed by ‘Finish’ to finish setting up your account.

It may not be immediately clear where your IMAP mail and folders are because they do not appear in the ‘Personal’ (local) folders. However if you look on the left, below the personal folders you should see an icon with the name of your IMAP account to the right of it. Click the small ‘+’ symbol to expand the folder and reveal all of your IMAP folders and emails.

Managing IMAP email with Outlook 2003 tips:

Deleting and moving emails

You may find that when you delete an email from one of your IMAP folders or move one from one folder to another that Outlook does not behave as you would expect. This may be because when you tell Outlook 2003 to delete an email it just marks it for deletion, which is portrayed to you by the email having a line through it, it does not move it to a ‘deleted’ folder. When you tell Outlook 2003 to move an email from one folder to another it copies it to the new folder and just marks the old one for deletion.

To delete emails which are marked for deletion you need to go to the ‘Edit’ menu and click on ‘Purge deleted messages’.  Note, this will only ‘purge’ the emails in the currently selected folder.

If you like the idea of having a ‘deleted items’ folder in operation you could move mails to your ‘Personal’ ‘Deleted items’ folder then purge the IMAP folder they were moved from before you exit Outlook.

To move an email, right click on it then click on the option ‘Move to folder …’ and choose which folder to move it too.

With all this purging it might be nice to have a quick short cut to ‘Purge’:

• Go to the ‘Tools’ menu and click on ‘Customize’
• Choose the ‘Commands’ tab and select ‘Edit’ from the box on the left hand side.
• Find ‘Purge deleted Messages’ in the right hand box and drag it to your tool bar (just next to the delete button for example)

Sound a little complicated? It is. I recommend Thunderbird.

WebDAV can be viewed as a network filesystem suitable for the Internet. It is an open, IETF proposed standard.

To connect Windows XP/2000 to a WebDAV share you will need to know the following infomation:

• The server address where the WebDAV is (this will most likely be a sub domain ie. dav.example.com).
• The folder (directory) name you wish to access.
• Whether you should connect securely (over https) or not.
• Any user names and passwords necessary to view/edit files contained in the share.

Once you have this information handy, click on the Start button in the bottom left of the screen followed by My Network Places. If you cannot see My Network Places, open My Computer then click on My Network Places under the Other Places heading on the left hand side.

Once you have the My Network Places window open, click on Add a Network Place:

You will now be presented with the Add Network Place Wizard. Click Next then, leaving Choose another network location selected, click Next again.

You will now be asked what the address of the network location is. Format it as follows; if you are connecting securely enter:

https://

Otherwise enter:

http://

Next you need to add the server address to that, followed by the directory you wish to access eg.

https://dav.example.com/webdav

Click Next again and Windows will connect to the server. Depending on the server configuration you may be asked for a User name and Password, enter them and then choose a name for your shortcut icon.

From now on, when you go to My Network Places you will have a shortcut to the WebDAV net share.

Possible problems:

1. As far as I am aware it is not possible to connect Windows XP/2000 to a WebDAV share running on a non default port ie. It has to be on 80 (http) or 443 (https).

WebDAV can be viewed as a network filesystem suitable for the Internet. It is an open, IETF proposed standard.

To connect Ubuntu to a WebDAV share you will need to know the following infomation:

• The server address where the WebDAV is (this will most likely be a sub domain ie. dav.example.com).
• The folder (directory) name you wish to access.
• Whether you should connect securely (over https) or not.
• The port number (if it is not running on a default http or https connection).
• Any user names and passwords necessary to view/edit files contained in the share.

Once you have this information handy, go to Places > Connect to Server… and select the Service type Secure WebDAV (HTTPS) or WebDAV (HTTP) – depending on whether you connect to your WebDAV share securely or not.

Enter the server name in the ‘Server’ field, directory in the ‘Folder’ field and your login name after ‘User Name’.

Add a bookmark if you like (this will put a shortcut tothe WebDAV share under the ‘Places’ menu) then click on connect. You will be prompted for your password if you need one.

That’s it!

Possible problems:

1. There seems to be a bug in Nautilus 2.28.1 which effects the creation and renaming of any files within a WebDAV share.

If you attempt to create a file or folder with a name other than the default name, or if you rename a file/folder you may get an error like this:

The item could not be renamed.
Sorry could not rename "untitled folder" to "New name": Bad Request.

After clicking ‘OK’, if you refresh the window by clicking on the ‘Reload’ button…

You will see that the renaming/creation did actually take place.  As annoying as this bug is, it won’t actually stop you from using the WebDav share, just ‘Reload’ after any file or folder activity.

The BCM4318 chipset is also found in Dell and Acer laptops

As Linux distros that support PPC are thinning out a bit and it was time for an upgrade, I decided to install Debian. I’m not sure why I haven’t used it as a desktop before, there is certainly no reason to get rid of my 12″ ibook G4 yet!

Anyway, just got Lenny installed and of course the wifi can’t work out the box due to the firmware not having a compatible licence. Fortunately this isn’t to hard to fix.

To double check if you have this wireless chipset run:

[user@localhost ~]# lspci | grep Broadcom

Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g

Then install the linux-headers and build-essential packages using apt (in my case):

[user@localhost ~]# apt-get install linux-headers-2.6.26-2-powerpc

[user@localhost ~]# apt-get install build-essential

If you’re not sure which kernel headers to install, running the command uname should help:

[user@localhost ~]# uname -a

Now it is just a case of installing the firmware package which comes from the ‘contrib’ Debian repos, which in turn grabs the firmware from openwrt.og, then dmps it in the right place.

Add ‘contrib’ to the end of the main Debian repo, like this (/etc/apt/sources.list):

deb http://debian.mirror.com/ lenny main contrib

deb-src http://debian.mirror.com/ lenny main contrib

Then install the firmware cutter using apt:

[user@localhost ~]# apt-get install b43-fwcutter

That’s it! Just say yes when it asks you if you would like to download and extract the firmware. Now if you’re using a graphical desktop clicking on network manager should now reveal any wireless networks in the area.

I had no trouble connecting to a WPA2 encrypted network using a 63 character key.

Being able to set a quota (limit the total directory size) on a WebDAV share can be very useful. Unfortunately, this is not supported by the Apache module mod_dav yet. There is, a patch available though and patching then recompiling the module is not difficult.

You can get the patch here.

You need to download the most recent ’system-independent’ version of the patch. If you have trouble translating the page it was the first link in the second group of links, about a third down the page, just use wget like this:

[user@localhost ~]$ wget http://leche.goodcrew.ne.jp/webdav/webdav-2.2.11-quota-2.4any.txt

Next you need to download the Apache source code. First, double check which version of Apache you have installed:

[user@localhost ~]$ rpm --query --info httpd

In my case it was version 2.2.3. Head over to http://archive.apache.org/dist/httpd/ and you should be able to find yours, again wget is your friend:

[user@localhost ~]$ wget http://archive.apache.org/dist/httpd/httpd-2.2.3.tar.gz

Extract the tar file, then cd to the httpd directory:

[user@localhost ~]$ tar -xvzf httpd-2.2.3.tar.gz

[user@localhost ~]$ cd httpd-2.2.3

You can now apply the patch:

[user@localhost httpd-2.2.3]$ patch -p2 < /home/user/webdav-2.2.11-quota-2.4any.txt

Configure it, enabling the modules:

[user@localhost httpd-2.2.3]$ ./configure --enable-modules=most --enable-mods-shared=all

And after it successfully configures:

[user@localhost httpd-2.2.3]$ make

You will now have versions of mod_dav.so and mod_dav_fs.so with support for quotas built in:

/home/user/httpd-2.2.3/modules/dav/main/.libs/mod_dav.so

/home/user/httpd-2.2.3/modules/dav/fs/.libs/mod_dav_fs.so

Copy them over your original versions in /usr/lib/httpd/modules restart Apache and you’re ready to go (it might be a good idea to back up your original modules before hand).

Apache config options

The extra option you can now add in your Apache config is ‘DAVSATMaxAreaSize’, this allows you to limit the total size of the WebDAV enabled directory.

For example:

<Location /dav>
Dav                                On
DAVSATMaxAreaSize       256000
DavMinTimeout               600
</Location>

A couple of notes on usage:

• ‘DAVSATMaxAreaSize’ is also inherited by subdirectories that have their own directory entry in your Apache config
• ‘DAVSATMaxSize’ is in kB’

An interesting bespoke project initially designed and developed by us and Reborn Media. We used WebDAV shares for adding content such as sermons, WebCalendar provides an easy way to add events which can then be shown on the home page and Wordpress was used for for a blogging.

Content from the blog and calendar is fed over RSS and iCal for any one wishing to keep in touch without checking the site.
