OSX: Per domain DNS servers

Little known OSX feature (or at least it was new to me): You can specify a separate DNS resolver configuration per domain. This can be useful to supplement or over-ride VPN connections. Best of all, it's really easy -- to specify a custom server for mydomain.int, just run: sudo

OSX Time Machine Backups to Solaris ZFS Volume

Tested on Solaris 11.1, Netatalk 3.0.4, and OSX 10.8.4 Goal: Back up the household laptops over the network to a solaris fileserver This seems to work better with AFP rather than SMB, so I installed netatalk 3.0.4 from source. Note: This was cobbled

Automated monthly ZFS pool scrubbing

Tested on solaris 11.1, but should work 10 and up. Just a quick shell script and cron job to perform a monthly scrub of all pools in your system. Whether this is appropriate or not depends on the frequency of data reads in your system and whether they would

Renaming Solaris zones

Tested on solaris 11.1 SRU 8, 4JUL2013 Goal: rename solaris zone name the ZFS dataset oldzonename to renamedzone, from the global zone perspective, and rename the ZFS dataset to match the new name. We'll also rename the non-global zone inside the zone. Here is the Oracle Documentation on renaming

Determining installed packages on Solaris 11

If we need to determine which packages have been added to a solaris 11 machine, say because someone is asking for documentation, or you need to build a similar machine/zone, we can use the pkg command's built in history function: Show everything, from all time: # pkg history -l Show

Automatic ZFS snapshots on Solaris 11

Solaris 11 has a built-in mechanism to take hourly/daily/weekly snapshots of your ZFS datasets, e.g. rpool/export/home. The service is called "time-slider", which can integrate with a nice GUI (which I don't have installed. Older snapshots are automatically deleted either when space is too

Solaris 11 Patching and Updates

Solaris 11 is patched differently to previous versions of solaris. Solaris 11 is installed and patched/updated from "Image Package System" repositories, typically over http/https. Oracle maintains two repositories, one public which is only updated with major releases, and a second repository which contains regular support updates

Solaris 11: Zone Boot environment selection

Tested on Solaris 11.1, specifically [email protected] I couldn't find this documented anywhere, so here's what I found. How do solaris 11 zones determine which boot environment to use? Seems they use ZFS properties. On my test zone, I have: root@

Solaris 11.1 -- Easy SMF manifest creation

The following command will generate a basic SMF manifest for a simple daemon process (in my case, the transmission bit torrent program) $ svcbundle \ -s service-name=application/transmissionbt \ -s start-method="/usr/local/transmission-2.76/bin/transmission-daemon" \ -s model=daemon \ > /tmp/xmiss.xml .. In my case, I want my

Zone installation errors on Solaris 11

Had a "checkpoint error" when installing a zone: 2012-12-10 00:58:35,549 InstallationLogger ERROR Checkpoint execution error: 2012-12-10 00:58:35,599 InstallationLogger ERROR 2012-12-10 00:58:35,649 InstallationLogger ERROR The following pattern(s) did not match any allowable packages.

Simple Solaris 11 Automated Installation Server (sparc client)

Enabling PLAIN LDAP binds on OSX 10.7 Lion and 10.8 Mountain Lion

OSX 10.7 and 10.8 have some issues talking to OpenLDAP and 389 (Red Hat Directory Server), because the server advertises non-plain BINDs in the root DSE entry, but these binds don't work when your user entries have hashed passwords (which they should). PS: 10.7.0 and 10.

Running X11 programs within a solaris 11 zone

Here are the list of packages I installed along with firefox to get X11 programs running within a solaris 11 zone: pkg install SUNWarc SUNWbtool SUNWhea SUNWlibms xorg-iso8859-1 SUNWmfrun SUNWxorg-client-programs SUNWxorg-clientlibs SUNWxwfsw pkg://solaris/SUNWxwplt truetype/fonts-core Thanks to this post for the starting point -- I've added ttf fonts
