Getting SMB Network Homes to Automount with 10.4 Client and Windows 2003 Server

I'd been wrestling on and off at work for a few months with a thorny issue.  Management wanted to see user's network home directories (hosted on Red Hat Enterprise Linux and manged with Windows 2003 Server and Active Directory) automounted for background syncing of select folders during user sessions.

Read on for a quick thing to check when AD integration begins to go south…

10.4.3 System Image Utility (Nice Feature)

I believe this is new to SIU as of 10.4.3.

You can now, when choosing the source for a Network Install, after clicking the ‘Customize’ button, select install options the way you would during a local CD install.

For the enterprise this is pretty nice – for example, at the newspaper where I work we have roughly 10 ‘remote’ offices connected to our core network by T1 lines. Removing the enormous number of unneeded printer drivers in the base install is quite useful in this scenario.

Resetting PCI RAID

If you are having trouble with ‘megaraid -destroyconfig’ run ‘megaraid -showdevices’ first to see drive status – stop rebuild processes with ‘megaraid -rebuild pd -stop’

Setting Screen Effects Defaults for Mass-Imaging

Not quite OS X Server, but since most of us do some kind of imaging…

Check out this command:

sudo pico /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/EngineDefaults.plist

This command is on one line, remember.

Does anyone know of other defaults this concept hold true for? (This determines what settings are used for "ByHost" plists, which are used by OS X to reset certain preferences after imaging).

***WIP*** cyradm Shared Folders syntax

I’ll incorporate this into the other article.

I had a deal of trouble with cyradm after installing it – things simply would not work as I wished (though the install was easy).

I wanted shared folders for employees at my client’s office, but couldn’t seem to hack out a shared folder in Other\ Users/ – then, while digging through the advanced config for Mozilla Thunderbird, I got it…

cyradm -u [usernam] [fqdn]
– here i entered my password as prompted-
localhost>cm Shared\ Folders/Spam
localhost>sam Shared\ Folders/Spam lrswip

(the order of the acl flags seems to matter)

(also, the master "Shared" Folder must be named "Shared\ Folder" – the \ escapes out the space in the name…)

SquirrelMail Sends, But Does Not Return User to Inbox

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.
