1. Unix Stuff
- 1.1. How do I boot into single user mode?
- Restart and press Appl-s
- 1.2. How can I enable sshd?
- edit /etc/xinetd.d/ssh - set disable to yes and kill -HUP xinetd if it's running or start it as root with /usr/sbin/xinetd -pidfile /var/run/xinetd.pid if it's not
Or from System Preferences check on the Remote Login box
- 1.3. Why is /etc/passwd, /etc/group, et al empty
- Darwin does not use the standard unix maps by default. Instead it uses something called NetInfo and lookupd. You can configure lookupd to use different name resolution agents to find information in various locations including NIS, LDAP, DNS, and normal flat files. Check these out for more information

- 1.4. Can I use kerberos to authenticate?
- Yes, but only from the loginwindow. See http://docs.info.apple.com/article.html?artnum=107154 for instructions on how to do this.
- 1.5. How do I mount Linux NFS shares?
- mount -t nfs -o"-P" host:/foo /mnt
or from the finder: Appl-k nfs://server/share
- 1.6. Can I authenticate against an NT domain?
- Yes, and no. You can authenticate against an NT domain when trying to mount an NT share but you can not force the loginwindow to authenticate against an NT domain.
- 1.7. Where have all the compilers gone?
- You need to install the developer tools freely available from Apple's ADC web site: http://developer.apple.com/macosx/.
- 1.8. Where is strace?
- The closest equivalent is ktrace(1)
- 1.9. How do I automagically mount file systems?
- Mac OS X has amd(8) built in although by default it seems to run automount(8). From the finder you can navigate to the Network icon.
- 1.10. Does Darwin really have a built-in firewall?
- Why yes it does. It's called ipfw(8).
- 1.11. How do I enable filesystem journaling?
- $ sudo diskutil enableJournal /
Timed out waiting for arbitration
Allocated 8192K for journal file.
Journaling has been enabled on /
$ mount
/dev/disk0s5 on / (local, journaled)
Or File->Enable Journaling (Appl-j) from Disk Utility
- 1.12. How do I run softwareupdate without having QuickTime pop up a confirmation window?
- export COMMAND_LINE_INSTALL=1 into your environment. See installer(8).
- 1.13. Why does squirremail send mail from user@getenv.mydomain.com?
- dunno - php thing? run sudo /etc/squirrelmail/config/conf.pl. Select 2 and set the domain name (1) explicitly.
- 1.14. How do I access a file's resource fork?
- assuming an HFSish filesystem... file/..namedfork/rsrc - likewise, file/..namedfork/data for the traditional part.
- 1.15. Why isn't the user's page refreshed when they send mail using SquirrelMail on 10.3 Server?
- It has to do with SSL and Server Admin. Check out http://docs.info.apple.com/article.html?artnum=107982
- 1.16. How do I change the startup disk from the command line?
- # nvram -p | grep boot-device
boot-device fwx/node@d04b311505e281/sbp-2@c000/@0:9,\\:tbxi
# bless -mount /Volumes/noisebox -setBoot
noisebox:~ root# nvram -p | grep boot
boot-device mac-io/ata-4@1f000/@0:10,\\:tbxi
#
- 1.17. How do I change the domain name used in Mailman web page links?
- # /usr/share/mailman/bin/withlist -l -r fix_url z-forsale -u z-world.com
