Microsoft's Mac OS X Exchange client, Entourage, operates in a syncing cached mode where it downloads server-side data, stores it locally, and occasionally synchronizes that data with Exchange. This setup in effect provides a local backup of your Exchange data that you can read when offline. At the university for which I provide computer support, I have seen more than one case where server-side issues have made the local backup of contacts and calendar items look very useful. Unfortunately, Microsoft does not provide any way to export or restore from cached Exchange data in Entourage.

If you find yourself in a similar situation, here's a workaround that takes advantage of Entourage's integration with Apple's Sync Services:

This method is for use when a user has an Entourage identity with an Exchange account that contains locally cached contact/calendar data that differs from and is preferable to the server-side Exchange data. This method will restore the locally cached Exchange contacts and calendar to overwrite the server-side Exchange data.

With the recent upgrades to Fedora 7 I have done on several systems, I have become more aware of the terrible state of VNC clients on Mac OS X. The issue arose when I set up Remote Desktop (vino) preferences on the Fedora 7 systems. The VNC client on other Fedora 7 systems and the Tight VNC viewer on Windows have no problem connecting to Fedora 7's vino server. I have found that the VNC viewer in Fedora Core 6 and any VNC client on Mac OS X throw back an "Authentication failure" when connecting. After typing in the target computer's hostname, the password prompt appears as usual.

The best way I have found to enable NFS on a Fedora system that has a firewall is to manually assign some of the NFS ports that are usually auto-negotiated and open just those ports in the firewall.

To do this, you can use Fedora's gui tool: system-config-nfs. In that interface, you can adjust the Server Settings as in the following screenshot:

...or just edit /etc/sysconfig/nfs to read:
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001
MOUNTD_PORT=4002
STATD_PORT=4000
