Mac OS X (Leopard) and ssh-agent

I had SshKeychain installed before and am trying to get back 10.5’s ssh agent to work. I found this article which pointed me to the solution and this fascinating file
From How to get Leopard ssh agent to work:

The solution is to use terminal, go to your home directory, cd to .MacOSX and look and see if there’s an environment.plist file. In there will be some XML to set this persistent string for SSH_AUTH_SOCK. You need to take that out. If there’s other stuff in the file, like a CVSHOME entry, hand-edit the XML to take out the SSH_AUTH_SOCK entry. (How to do that is beyond the scope of this post.) If the only thing is that entry, just delete the environment.plist file.”

And this is an even better article that describes the the past situation, how it works now, and the integration with launchd

Mac OS X (10.5), NFS, and Linux

I got around to getting my MacBook to mount an NFS filesystem from my Linux server. There’s a nice set of instructions on using the Directory Utility to do so. The problem stumping me was:

kernel: nfsd: request from insecure port (!

And the bit of magic that eluded me before was adding the “-P” option:

Unfortunately, my uid on my MacBook is 500 and on my Linux server it is 1000.
There’s an option for more recent implementations of NFS that allow the
/etc/exports file to include a ‘map_static=”/etc/nfs_map”‘ option to specify a
uid mapping but it’s not available in OpenSuse.


Updated to latest XQuartz (from 2008-09-15)

The Xquartz project is an open-source effort to develop a version of the X Window System that runs on Mac OS X. Together with supporting libraries and applications, it forms the that Apple has shipped with OS X since version 10.5.

NewNewsWire and NewsGator

Ok, maybe it really is time to try that new fangled thing: RSS Feeds
First, I signed up for an account on and then I opted to use NetNewsWire for my Apple MacBook and this one for Microsoft Outlook.
From Mac RSS Reade – NetNewsWire by NewsGator:

Looking for an easy-to-use RSS and Atom reader for your Mac? You’ve found it!
The Eddy award-winning NetNewsWire has a familiar three-paned interface and can
fetch and display news from thousands of different websites and weblogs. ”

Time capsule rules!

I’ve got to admit, Apple’s Time Capsule rules!
Starting off was a little slow. The initial backup was 60Gbytes or so and took
nearly 16 hours to finish. I did this over the wireless connection. It
wasn’t a big deal. I had my laptop plugged in and just left it on overnight.
The transfer rate average to be about 1.2MB/sec (~10Mbit/sec) but as you are
watching, it really drags on
My girlfriend’s MacBook got backed up as well.
So now I’ve got this nice wireless backup going on. Both laptops share the backup drive without interference.
It’s a little of a let down at that point. You start up “Time Machine” and all
you see is exactly what’s on your desktop. After that, it starts to back up
every hour. The interface took a few tries before it really sank in how it
works. I’d expected to drag and drop to get to a backup file since it provides
a “Finder” interface to the backups. Instead, there is a “Restore” button to
bring things back.
Another thing that outsmarted me is that I kept checking for when the next
backup would happen. But it wouldn’t happen. The big “Power off” letters in
the Time Machine menu didn’t click for a long time. Finally, I realized it
wouldn’t do the backup unless I add my laptop plugged in to power. Makes pretty
good sense since you don’t want a lot of disk activity if it’s running on
In the event of a my laptop disk failing, I’m supposed to be able to have the
install disk go to the backup and recover the system to any point in time.
Hopefully, I’ll never have to find out if it works but what’s the expression:
“Hope is not a plan”.
