Had an Xserve with the RAID card on order since before time began?

As of 10.3.5 you can take a look at man megaraid or at Apple’s RAID card docs and learn how to use it before it comes.

Ever wished that you had setup your Mac OS X Server with a boot RAID before you installed everything? Afraid that making a RAID mirror now will require you to backup, format, and restore?

Read on to see how to create a RAID mirror without formatting your drive.

This script synchronizes AD group membership with OD group membership.

Use this to better manage MCX settings for AD groups. You can download it here.

I’ve occasionally encountered IMAP mailboxes that were unreadable and undeletable
using any mail client. In Mac OS X Mail, this usually produces an “Unable to Select” error.

Here’s how to fix the server-side mailbox. At the bottom is a bonus: how to recover the locally cached .imapmbox file from Mail.

A detailed overview of how to integrate OS X clients into an Active Directory environment while still retaining the ability to manage the clients with the OS X Server tools.

Now up to version 1.4. Lots of changes including a section on troubleshooting. Grab the AD Integration pdf here.

I’ve noticed at times that although I can send mail in SquirrelMail on OSXS, I can’t see any visible sign that the mail went out – I don’t get redirected to the Inbox, and can only see that I’ve sent mail if I look at the Sent mailbox…

Check out KB#107982 for the fix.

I recently came up with the idea of using sieve scripts that I installed using Joel’s article to filter my spam. I work for a University that filters all mail that comes to our site mail server through spamassassin. Messages that they suspect are spam get marked with the header X-SPAM-Level: and a number of stars. This header was unavailable in the sieve plugin of squirrelmail. I found that under /usr/share/squirelmail/plugins/avelsieve/config.php there is an array that holds the values of the headers you can use. I added my specific header in, saved it, went back to squirrelmail, applied it, and everything worked great. I sent a faked out test message with a spam level that I specified and it bounced back with the message “I don’t like SPAM!” so I know it worked.
You will want to search for something looking like this in your config.php file.

/* Headers to display in listbox widget, when adding a new header rule. */

$headers = array(
'From', 'To', 'Cc', 'Bcc', 'Subject', 'Reply-To', 'Sender', 'List-Id',
'MailingList', 'X-ML-Name', 'X-List', 'X-Mailer', 'X-MailingList',
'X-Mailing-List', 'X-Spam-Flag', 'X-Spam-Status', 'X-Spam-Level', 'X-Priority', 'Importance',
'X-MSMail-Priority', 'Precedence');


Now that you know how to make a SSH tunnel how can you make it work without a password challenge?

Useful for automated processes, and lazy fingers, a public-private key set may be what you are looking for. You can also use keys with a passphrase for even more security.

Stuck behind a draconian firewall and you need access to your Mac OS X Server? Read on to find out about the only tunnel on your Mac where you are not likely to be eaten by a grue…

After a software update and reboot together with some system tweaking, my personal webserver was not loading httpd successfully. I checked /var/log/httpd/error_log and found this: "[alert] mod_unique_id: unable to gethostbyname" followed by my hostname – actually, the hostname I had specified when setting up my server.

I had changed the Rendezvous name in Sharing Preferences, and forgotten that my hostname would be changed too – this conflicted with settings in httpd’s conf files. For now, I’ll just switch off the unique id module in Server Admin under Web service.

Web service is back up.
