iPhone 3GS, iOS4 and MMS not working

I ran into a problem with MMS after I upgraded to iOS4 on my iPhone 3GS. Somehow, it was impossible to send MMS messages on the KPN cellular network. Searching the Internet revealed that I wasn't the only one.

The general consensus to solve this issue was a restore of the iPhone and not to restore old settings, but start from scratch.

After doing this, MMS still couldn't be sent from the iPhone, so time to do some more research. It turned out that KPN must have change the MMS settings, since my old MMS settings weren't correct anymore. So try these settings BEFORE you restore your iPhone. It might save you a lot of work and time.

Note: the following settings are for the Dutch KPN Network, and probably won't work on other networks / carriers.

Old Settings

APN: portalmmm.nl
Username:
Password:
MMSC: http://mp.mobiel.kpn/mmsc
MMS Proxy: 10.10.100.50:5080
MMS Max Message Size: 300000

New Settings

APN: portalmmm.nl
Username: kpn
Password: kpn
MMSC: http://mp.mobiel.kpn/mmsc
MMS Proxy: 10.10.100.20:5080
MMS Max Message Size: <leave empty>

Notice the differences? Anyway, with these new settings, MMS worked again.

KPN does have a page dedicated to the iPhone (in Dutch), regarding the Internet, and MMS settings. Just check those pages for the lastest settings.

I've updated the original page on my blog with the new settings.

OS X Kerberos / Open Directory Logging

Ever since I switched to OS X server at home I use Splunk> to see what's happening 'underneath the hood'. This revealed that there's a lot (really a whole lot) of Kerberos logging going on. Each and every day I get thousands of log entries regarding krb5kdc which results in over 1 million log entries only for krb5kdc in little over a week.

These syslog messages only contain the following 'text';

krb5kdc[16179](debug): routing msg not interesting
krb5kdc[16179](info): got routing msg type 5(RTM_LOSING) v5
krb5kdc[16179](info): routing socket readable

Looks like that the debugging level is set to debug (why??). And why can't we change it? Others seem to have this problem as well.

Looks like that the following command seems to work:

sudo defaults write /Library/Preferences/DirectoryService/DirectoryServiceDebug "Debug Logging Priority Level" FALSE

After entering that 1 line I haven't seen any new logentries in the kdc logs. More info on that command can be found @ Apple.

Nevermind......

Slow Open Directory on OS X Server

Ever since I've been playing with my Mac mini with OS X server 10.6.4 I have had on-and-off problems in the authentication/Open Directory area.

• Some accounts authenticate really quick, while others take minutes to authenticate.
• Accessing the Open Directory through the Workgroup Manager is as slow as a slow boat to China. Changing users (just by selecting them) takes another boat along the Pacific.

So it was time to start digging into the phenomenon called 'Open Directory'.

The manual from Apple isn't much help in troubleshooting a slow Open Directory, so it was time to search the interwebs and start experimenting. If it didn't work, I can always reinstall the entire server from scratch.

The Problems with Apple OS X (10.6.4) Server

Updated on Monday, July 12, 2010 at 21:48 by Willem

It has finally been done. I've switched off the old Windows 2003 server at home and officially replaced it with an Apple Mac mini server. For now... And with 'for now' I really mean for now. It turns out that Apple OS X Server doesn't resemble its client counterpart at all. Where the client is stable and intuitive, the server edition lacks both.

I'll try to explain why I think there's lots of room for improvement. Mainly stuff I ran into while configuring the server/services.
Since the Windows fulfilled several functions, I needed these functions to be available on the OS X server as well. These were;

• Networking services like DNS and DHCP
• Webserver
• Mailserver
• MySQL Database
• SSH Server
• File sharing on the internal network
• Public Key Infrastructure for issuing certificates
• Download station

Evaluating these functions, one would think that this shouldn't be a problem. Well it actually is.... At least some of those features.

My iPhone 3GS and iOS 4

Apple released the latest Operating System/software/firmware for the iPhone. This new OS (iOS) adds several new features and lots of enhancements (which I wont be going into).

I upgraded my iPhone earlier this week. No problems with that. The only real hick-up I ran into was the Voicemail number. The phone had forgotten the Voicemail, MMS and Tethering settings, so I needed to add it again. Even tethering was still available on the SIM-lock free iPhone with the KPN carrier.

There's one thing that's not 'Apple' about this update. With the regular Apple operating systems there's always the experience that an upgrade to a new release (10.4 -> 10.5 -> 10.6) leaves you with a faster/snappier OS. Even if the hardware is relatively old. Don't know how they do it, but it's something that Microsoft hasn't accomplished yet since MS-DOS 3.

Anyway, the OS upgrade on the iPhone is completely different. The device is less snappy. It looks like the device goes into some sort of suspended animation and when you need to use it it takes a couple of milliseconds (it's not much, but it's noticeable) for the phone to react. After a couple of seconds it seems to be gone.

For me, the new/improved features are more important than the snappy-ness of the device, so I'll stick to the new iOS for the moment.

Installing Adobe Coldfusion 9 on OSX Server 10.6.4

Updated on Tuesday, July 20, 2010 at 11:08 by Willem

Updated on Friday, July 30, 2010 at 7:53 by Willem

After Apple updated the Mac mini to it's current form (mid 2010), I decided that it was time to start replacing my 'faithful' Windows 2003 server with something a bit less power consuming. The original Mac Mini was basically a consumer device, but a while back, Apple released a server version of the device. The main differences are:

• Only 1 CPU model available (2.66GHz at this moment)
• No DVD drive
• 2 * 500GB internal disks
• OSX 10.6.4 Server edition (unlimited clients)

Basically everything you could ever need for a server with a very small footprint.

The installation of Coldfusion is not straight forward. Not that I expected it to be [1], [2], [3], but one keeps hoping on an installer that actually installs the complete package, and where you don't have to edit files yourself to get it to work. It's not that it's the very first version of the scripting engine......

Anyway, the installer guides you through everything needed to INSTALL the software. Getting it to work comes next....

SafeSign and Apple OSX Snow Leopard

Last week I got an e-mail from one of the product managers @ AET Europe regarding the availability of SafeSign / Tokenlounge for OSX Snow Leopard.

The content of the e-mail wasn't very encouraging.... It seems that the Snow Leopard of SafeSign / Tokenlounge release is delayed by a bug in the Apple Keychain;

---------
We use systemkeychain -T to create a login keychain (for a new FV user) associated with our token. When trying to unlock this newly created keychain during login with the smartcard, we get prompted with the "unable to unlock login keychain" panel - as you have observed -.
This is basically our main concern, as this was perfectly running under 10.5. Any idea why the system wants to update the login keychain password, prompting the user with that panel???

What we have discovered beside, is that when you click Create New Keychain on that panel, the keychain gets encrypted with the PIN of the smartcard instead of the RSA key, which is a major security issue (Same behavior if you click Update Keychain Password)...
You can easily verify this last issue by removing your smartcard, launching Keychain Access and entering your PIN code to unlock the keychain...

Once again, we didn't have this kind of problems with Leopard.

As long as this issue isn't resolved, there will be no version for Snow Leopard. The (security) risk is just too big.
-------------

So, we need to be patient, and wait till Apple solves this. In the mean time, when you need the SafeSign software for your every day work, you shouldn't upgrade to Snow Leopard.

Check the follow-up on the original SafeSign post for the availability on the Leopard version of SafeSign / Tokenlounge.

DIY Porn on the iPhone

Updated on Tuesday, December 13, 2011 at 23:25 by Willem

Most of the regular iPhone / iPod Touch users already know that there's no sign of porn or erotica to be found in the Apple App Store. Reason for this is (according to Steve Jobs);

You know, there’s a porn store for Android. You can download nothing but porn. You can download porn, your kids can download porn. That’s a place we don’t want to go – so we’re not going to go there.

So no porn for the iPhone (at least not the jailbraked versions), or is it? It seems that Apple facilitates the biggest 'app' for getting your porn 'fix'. The app is called 'Safari'. The good old browser. The application that made the Internet for what it is today. As an alternative you can use iTunes to provide you your 'fix'.

Note that eventhough I'm talking porn/erotica here, you can project this to any piece of content.

Before continuing, I must warn you. The complete article might have some explicit pictures, so continue at your own risk. I can't and won't be held responsible for the consequences.

Apple Released OS X Update 10.6.3

Apple released the .3 update to Snow Leopard (10.6) today. You can find this update under the Software Update menu, or on the Apple website as a single (combo) download [.dmg].

The update was ~450MB, and took about ten minutes to install. After the reboot everything seemed to work fine. Some applications (I guess the ones that got updated) reverted back to their default settings. E.g. Firefox wasn't my default browser anymore, but NetNewsWire was still my default RSS reader.

I also thought that QuickTime X (how I dislike that app....) reverted back to its default settings, since my pr0n..... euh movies started opening in different windows. Since I can't find a Terminal command for this on the Internet, I guess that I'm mistaken on that. I might be confusing the excellent QuickTime Pro v7.x with this piece of whatever.
There are no visible enhancements on QuickTime X

An annoyance that got fixed is the deletion on SMB shares (Windows 2003 Server). Without the update, the files got deleted, but the directory they were in stayed behind. When you tried to remove this directory, you got this fancy error code.

The important pieces of software that functioned properly after the update uncluded:

• Adobe Photoshop CS4
• Adobe Lightroom v2.6
• BBEdit v9.2.1

Anyway, (more) updates will follow when I run into unexpected behavior.

Update on Tuesday, March 30, 2010 at 8:42 by Willem

Apple also released a security update for OSX 10.5.8 (Security Update 2010-002). The update (in my case) was 210MB and installed without (a noticable) flaw on my iMac.

iPhone 3GS Tethering with Firmware 3.1.3

Updated on Thursday, February 4, 2010 at 8:38 by Willem

With the release of firmware 3.1.3 the tethering option is back on the iPhone. After the reboot of the iPhone you get additional fields in the 'Cellular Data Network' section in the 'Network' menu (Settings -> General -> Network -> Cellular Data Network). Just enter the appropriate information in the APN field (for KPN in the Netherlands enter internet in the APN field) and the Internet Tethering option is back (w00t) in the 'Network' menu.
