AFP Mounting Breaks After Updates
 

I updated my 10.4.8 MacBook Pro with a bunch of the latest Apple OS updates. A lot of them concerned wireless networking; others were the new QuickTime and iTunes.

After updating, I connect remotely mount AFP servers. Another Mac can remotely mount them, so the server itself is not the problem (I could connect to this server before the update).

Also, I tried creating a new user account locally and logging in. That produced the same error, no it is not a userspace problem.

When I use the Finder to mount the AFP volume, I get Error code -35, "The operation cannot be completed because one or more required items cannot be found."

Using the terminal:

sudo mkdir /Volumes/user
sudo mount afp afp://user@machine/user /Volume/user

mount_afp: the mount flags are 0000 the altflags are 0020
mount: /Volumes/user: Segmentation fault

I have pasted in the AFP crash log below from mount_afp.crash.log , but I have no idea how to read it. Can anyone help?

Download and install the 10.4.8 Combo updater for Intel. It's somewhere at http://www.apple.com/support/downloads/

Unfortunately, I have a new Mac Book Pro Core 2 Duo, and the 10.4.8 Intel combo updater will not install on my machine.

I have the same problem as talkitron.

The SMB protocol won't let me connect to the external drives of my mac mini from my laptop. It does let me mount one volume. It is really uncool without AFP.

I don't have the talent to figure this out on my own; I looked in the System Preferences and was unable to come up with any ideas. I'm sure willing to try a manual solution (learned the unix that i do know from trying to configure gentoo stage one installs).

Thanks all!

I downloaded and installed the 10.4.8 combo update (all 290 megs) and, sadly, there's no AFP. :confused:

Is there a way to uninstall updates?

mp

well there are a few things you can try here....

1) If you have another macbook pro lying around you can target mode boot the problematic one with the other and use the cp command to copy over some of those frame works and what not and over write them with known good copies. Though it looks like the problem is the kernel can't access things in memory, or it is erroring out when doing so...

2) Run fsck -fy in single user mode or in disk utility and see if it can not fix anything.

3) Try third party apps like diskwarrior.


You can also look through your system log for anything relating to afp under /var/log/system.log. You may want to search through that stuff and try maybe something like this

See all the specific errors that come up with AFP, you can also try to browse through the logs for the other things in your AFP error log to see if anything may be causing the problem.

Go into your ~/Library/Preferences and delete all the com.apple.Appleshareclient.plist or any plist that may refer to the afp client.

Does this problem persist in a brand new user account?

OP Poster Here
 

I'm the original poster. I did repair the disk using Disk Utility, but the changes were so minor I didn't feel, technically, that they were likely to get AFP working again.

I ended up reinstalling the OS from the 10.4.8 disks that came with my MacBook Pro. When I was creating the first account as part of startup, I used my old user name and password. Somewhat amazingly, after the reinstall my account was exactly as before and all of the applications I had installed just worked, and even the Apple software updates (iTunes 7.1 for example) were still installed.

Amazing.

sounds like you did an archive and install off the OS X install disc

Uggh, the problem is back. After upgrading to 10.4.9, I could not hold a wireless connection because of a problem with the System Keychain.

I followed a hint on MacOS X Hints to junk and recreate the system keychain. That allowed me to resolve the wireless problem.

But now the AFP problem is back, and more importantly now the old error code -35: "...one or more required items cannot be found" is reappearing when I try to mount an AFP drive that worked a few hours ago before the update.

Reapplying the combo updater does not fix the AFP issue. I cannot upgrade my old OS back to 10.4.8. I guess I will have to do an archive and install, again if I did it the first time.

Updates, damn you.

How are you trying to mount the volume? By double-clicking an alias? Try using the Connect To Server dialog to explicitly enter the server address. If that works, delete your existing alias and make a new one.

I was using the "Connect to Server" dialog box in the Finder.

I spent about six hours to fix this. After installing 10.4.8 from disk, I reinstalled the 10.4.9 combo updater, only to find the wireless problems and AFP issues.

I reinstalled Mac OS 10.4.8, then reinstalled the patches other than 10.4.9. As before, patching the 10.4.8 causes AFP issues. Again as the first time, I reinstalled 10.4.8 from disk (the third time today!) and now everything works well, just like I had it before the application of the 10.4.9.

Not surprisingly, in the absence of a technical answer as to what is going wrong, I am really gunshy about applying the 10.4.9 patch. One thought is to skip more patches until 10.5 is released, then to wipe the computer and start over.

The afp protocol has been broken in the last two Apple updates, at least on Intel machines. The problem is in the kerberos framework, which is a library of code used not only in afp but also in ssh if you use the default level 2 instead of specifying level 1. It is annoying that Apple hasn't apparently dealt with this.

Anyway, the fix is to replace the kerberos framework with one that is old enough to not have the broken code. I downloaded the 10.4.8 Intel combo updater file from Apple- this version works.

Then you need a program that can extract and replace individual modules from the updater package. A good shareware tool for this is Pacifist, which you can find by googling the name. Run Pacifist, extract the zipped file called Archive.pax.gz, and un-gzip it. You can find the acrhive in the updater file because it is so large, and will be obvious in the Pacifist window.

Then use Pacifist to select and reinstall just the Kerberos.framework (see Pacifist instructions, but it's just point and click stuff). This will replace the library and afp and ssh will both come back to life.

Incidentally, save both Pacifist and the combo updater archive file as I have had to do exactly the same thing for two updates now. It will likely happen next time too.

Maybe it's because I don't use secure AFP connections, but I'm using 10.4.8 on a Mac Pro and Kerberos is working great for me.

afp error -35 on intel macs
 

The original 10.4.8 update seems to have the working code in it, that's why I used the combo updater file. That's probably why your machine works. I first noticed the problem in a security update to this package, and had to fix it with Pacifist. All was well until the 10.4.9 update, which broke it again.

If you have access to a machine that allows ssh connections, you can test your system by typing "ssh machine.ip.address.orname" in a terminal window. To make sure you are using ssh level 2, try "ssh -2 machine.ip.address.orname." ssh will generate a segmentation fault if you have the broken kerberos library.

If not, connecting to an apple server using afp will give a -35 error after a timeout if your software is hosed.

Anyway, the problem is fixable but it's a pain to have to do this each time. And if Apple makes more modifications to its networking software then replacing the kerberos framework with the older version could really break the networking setup.

Thanks for the detailed explanation about the Kerberos problems, hz_mac. When I get a block of time where I could reinstall everything if Kerberos is not the issue, I will try your solution.

Thanks a bunch!

OP here, the problem has returned without me knowingly installing any updates. I am still on 10.4.8; the problem showed up after waking the computer from sleep.

I am going to try the Kerberos fix. I will keep everyone updated.

Arghh!

Now that I think about it, my Kerberos works fine in ssh. If I type

ssh -2 machinename

I can remotely log in fine. Same goes for version 1 of ssh.

I have a similar problem.

Mine occurred when we updated to 10.4.9. I am using an ethernet connection.

I, also, can SSH into the machines fine... simply can't connect via AFP.

is the error over wireless? The 2007-02 airport update botched lots of third party support as well with wifi connections.

Mine is not. My error occurs tethered to an ethernet cable.

My AFP issue occured with both ethernet and wireless, although upgrading to 10.4.9 caused a separate issue with wireless.

So I erased the hard drive and reinstalled from the 10.4.8 discs that came with my machine. I immediately upgraded to 10.4.9 (and other updates) after first log in, even before syncing with .Mac.

The machine works fine after a few hours.

Note that it was importat that I erased the drive. Archive and install was not a permament fix.

Oh come on!

There has to be some other fix than erasing the damned hard drive!!!

Are there any trollers on here from Apple?

:mad:

Thank you, thank you, thank you....

This has been plaguing me for months!

I reinstalled the kerebos framework from the combo updater using Pacifist... and voila! AFP and SSH are back!

Note - merely running the combo updater did NOT fix the problem. Forcing the re-install of the kerebos framework using Pacifist DID fix the problem.

What files are responsible for the kerebos?

I downloaded the 10.4.9 updater pkg that had originally caused my issue. But, am unsure how to reinstall the kerebos framework. Can you be a tad more specific, please?

Ok, I forced the re-installation of my kerebos frameworks and nothing, nada, nil.

:(
