Re: News around MacOS X

the bad:
* if you do an upgrade (archival) and you had some kernel patches installed in 10.2x, get ready for some headaches. if your system hangs, you can ssh in trough the back, which makes things easier to fix. therefore my recommendation is a clean install. if your system hangs due to kernel problems, then you are screwed. another option is to boot into console mode (user: >console, password: console) to do some debugging.
* X has been moved from Applications to Applications/Utilities/. be sure to change the path. in my case the install did not remove the old X and so things were utterly hanging until i realized that.
* since X was moved, all the fink packages were also broken. therefore, after installing 10.3 i recommend you get the latest fink version 0.5.3 (i think) and reinstall it from scratch as well.
NOTE: at this point i would like to ask our admins to install the whole fink distro on the D-PHYS macs to make them more compatible with the linux machines.
* issues with the crypto filesystem: i could be wrong and i have not fully tested it, but if i am not logged into the console X interface, and ssh into the machine, i will not have access to my files because they are encrypted. does anyone know a way around this? is there a command to issues on the command line to get the homedir back?
* i did an upgrade and now and then my system behaves funky: some preferences are lost, things are reverted to defaults, ...
the good:
* expose rocks! i wish linux had something like that. finding stuff on your workspace has never been easier!
* the system runs noticeable faster. clearly many things were optimized in panther.
* apparently finder is much better now. i never used this because i think that if you cannot find your stuff you should clean up more often. conversely the wonderful unix tool "locate" is installed and can be run on the command line. muuuuuch better.
* crypto filesystem: best idea ever for a laptop. if you lose it, you do not have to worry too much about people getting to your stuff. little drawback: the system is a bit slower when writing and accessing files (you will feel it when you ssh large files).
* preview now understand postscript files. whoa!
* i guess fast user switching might also be a great feature for an institute machine. i have nit tested it.
* and finally if you have not tried iChat AV, you are missing the best feature.
NOTE: it would be nice if the D-PHYS admins had a mac with iChat in their cave so what we can chat with them online when we need someting!
Final comment on Apples new upgrade policy: This is nothing new. Redhat for example dropped their free products from one day to the other and now they charge $180 PER YEAR for a license of (what should be free) linux. makes you wonder...

Thanks a lot for your posting! Here our comments:

It will be a huge work to keep the software from Fink (usually bleeding edge) and Debian GNU/Linux (usually "stable") in synch. We assume that we will stop installing Fink on our workstations and instruct the users to use ssh to one of the Linux workstations.

Nice idea :-) On the other hand, the world except Apple uses H.323 for video and audio communication over the net. For example Microsoft's Netmeeting or GnomeMeeting. Because of this issue, it's unclear which kind of video conference we should support in the future.

| A comment from the Linux User Group meeting friday night: No more classic when new installing! Why that?
The CD-ROM Version of 10.2. required to install MacOS 9 before or after MacOS X to get a working Classic. This is no longer a solution for systems who won't boot MacOS 9.
The DVD-Version of 10.2. contained a MacOS 9 system to drive Classic. This is no longer the case with the current 10.3. install CD set. The new G5 and all future System won't boot from those DVD anymore.
On the other hand, Classic has several improvements over the version distributed with 10.2. It is worth to go through the configuration.

Final comment/warning:
As mentioned in my earlier post, I did an archival update. Well, In my case, things are now completely messed up.
I am not sure what conflicted with what else, but several files are corrupted and so I am not forced to do a clean install...
Cheers, h.

NFS on Panther
by Beat Rubischon on Tuesday November 11, @10:08AM

In 10.3, Apple integrated the new NFS stack from FreeBSD 5 into their system. Several problems together with Linux fileservers arrived:
- Apple's rpc.lockd uses 20 bytes cookies and Linux only accepts 8. You see kernel: lockd: bad cookie size 20 (only cookies under 8 byte
s are supported.) in the server's logfiles.
- You may patch the Linux kernel with this patch
- FreeBSD knows about this problem and has also a fix for FreeBSD 5.1
- rpc.lockd of Darwin and FreeBSD drops root priviledges before opening the socket - on the other hand, Linux only accepts locking requests from priviledged ports. You see kernel: nfsd: request from insecure port (XXXXXXXX:YYYYY)! in the server's logfiles.
- FreeBSD has a patch fro FreeBSD 5.1, but it seems to be a dirty hack.
A quick and dirty solution is to disable locking on the client. Add the line NFSLOCKS=-NO- to /etc/hostconfig. You loose locking but since 10.2 did'nt have locking, this is not (yet) a problem.
You may also export the filesystem with the insecure option. But this is not a solution in a environment as ETHZ where untrusted users works on the machines.
The patch for FreeBSD may be applied to the Darwin sources. We'll see!

Patching the Linux kernel and rpc.lockd from MacOS X works. See our readme about this topic.

Re: NFS on Panther (Priv Port)
by James Hammett on Tuesday March 30, @11:26PM

You can also use the -P option. This tells mount_nfs to use a priviledged port. (However I don't know how you'd do it from the finder).
(You can also add it into one of the arguments stored in your netinfo mount directive)

Re: NFS on Panther

I have a problem where I export a file system from a linux machine that is owned by root and has permissions 700 (so only root on the client can read/write to it). This works fine on 10.2 but fails on 10.3. Any ideas on why and a workaround are appreciated.
Thanks

Authentication

It tooks me a lot of work to find out how MacOS X 10.3 authenticates and collects information about hosts, users and groups. See the results in my readme.
