To adjust the various system preferences from the command line you need the systemsetup utility which ships with OSX Server although I’ve found some versions of OS X client have it installed in /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Support. On my G5 with Tiger (10.4.8) installed I used systemsetup-tiger and on my iMac (Intel) that was missing so I used systemsetup-panther which also worked.

You can adjust all sorts of things with the tool -help shows you all the options, I wanted to adjust sleep times. Below is an example session, showing the settings before and after I had made the change

# ./systemsetup-panther -getsleep
Sleep: Computer sleeps after 10 minutes
Sleep: Display sleeps after 10 minutes
Sleep: Disk sleeps after 10 minutes
# sudo ./systemsetup-panther -setcomputersleep 60
setcomputersleep: 60
# ./systemsetup-panther -getsleep
Sleep: Computer sleeps after 60 minutes
Sleep: Display sleeps after 10 minutes
Sleep: Disk sleeps after 10 minutes

Just found this hanging around in an ‘undated’ folder, I carried a zippo of one kind or another for over 10 years and now I dont even know where any of them are!

So the office has had a spring clean, I’ve got 50% less computers and a smaller desk. I think I like it! /me taps fingers waiting for iMac

I’ve moved this post into a page specifically about the SystemRescueCd which can be found here (Broken link /systemrescuecd-network-boot/).

I’ve recently spent some time trying to get linux running out of the embedded firmware on a Compaq Evo T20. I’ve succeeded with a lot of help from this page. I’ll be adding some notes on how I did it and how I used ThinStation to get the NX client in the firmware.

To add an alias to a network device on freebsd do this:

[root@book etc]# ifconfig fxp0 alias 10.0.0.2 netmask 255.255.255.255

Note: The netmask is always /32

To remove one do this:

# ifconfig fxp0 -alias 10.0.0.2

To add these to rc.conf do something like:

ifconfig_fxp0="inet 10.0.0.1  netmask 255.255.255.240"
ifconfig_fxp0_alias0="10.0.0.2 netmask 255.255.255.255"

I never remember how to do this, if you need vendor specific bits inside a spec file (like init scripts etc) you can use this to do different things depending on vendor.

%if "%{_vendor}" == "suse"
  # Suse specific stuff
%endif
%if "%{_vendor}" == "redhat"
  # Redhat specific stuff
%endif

If…else works like this:

%if "%{vendor}" == "suse"
  # Suse specific stuff
%else
  # Redhat specific stuff
%endif
