Well worth a read: Linux to Solaris Administrators Guide. The competitors have long had Solaris to linux guids, so it is nice to finally see a guide leading people back in the right direction.
Also, there's plenty of other sysadmin documentation in Solaris 10 System Administrator Collection, in the How-To Guides and on Bigadmin.
Or for the really basic instructions, try the OpenSolaris Screencasts.

Solaris 11/06 has been released

The latest Solaris has just been released. I've had the pleasure of testing the beta for a few months, but now it is available for general download.
The release notes detail plenty of exciting new features. For me, the interesting bits are all the Zones and ZFS improvements, finally having "Secure by default" and I'm starting to think that Trusted Extensions would be well worth a look as well.
So, that's the first "christmas wish" come through - now if we could just get Cluster 3.2, that should be enough toys to keep me busy well into the new year ;)

2 troublesome patches

Lately I've run into two Solaris patches that broke things for me:

122663-06 libzonecfg patch
Breaks zone related utilities and can't be easily uninstalled if you already have zones on the system because patchrm wants to check the patch in all zones even if passing -G (having another unpatched machine handy made it easy to replace the 3 files).
120051-04 usermod patch
Breaks tools like user/group/role add/del/mod - simple patchrm is enough to fix: useradd: fatal: version `SUNW_1.22.2' not found
(required by file /usr/sbin/useradd) useradd: fatal: open failed: No such file or directory

At least 120051-04 has a sparc counterpart (120050-04) that leads to the same problem, but I'd not be surprised if the same was the case for 122663-06.
UPDATE: there's a Sun Alert for the issue with 120051-04.

Sun is giving away free media kits.
The kit includes:

For those wanting bleeding edge and not minding downloads, there's also the option of grabbing Sun Studio Express and Opensolaris.

Opensolaris user groups

Thursday night I went to the first meeting of the Netherlands Opensolaris User Group.
The program was quite interesting (even if I only understood half of it). Both Bart Muijzer and Casper Dik spoke in dutch but at least their slides were in english so that I think I might have understood the important parts and only missed most of the jokes. The one joke I didn't entirely miss was the one about why they chose NLOSUG rather than NOSUG. The main talk of the night was Darren Moffat talking about opensolaris development and zfs crypto. The zfs crypto project looks very interesting and I was quite pleased to hear that many of the hard bits in the implementation of an encrypted filesystem already has been identified and are being handled in the implementation. I hope Darren will soon manage to get some code online because I think this code has the potential to become one of the most solid implementations of an encrypted filesystem and by using the Solaris crypto providers, support for hardware acceleration and key storage should be simple.
The turnout was quite impressive with something like 60 people there.
The trip there and back again was a bit more interesting than I had planned. First was a 1:30 train ride through Utrect to Amersfoort and then the fun began. I'd looked at the usually quite practical 9292ov site and found that the last bit of way from the station was supposed to take around 30 minutes involving 2 busses and a fair bit of walking as well. Rather than having to deal with that, I opted for the 45 minute walk that viamichelin suggested. Note to self:not all routes suggested by them for walking are good - a sidewalk would have been a nice feature rather than having to walk the grass at the roadside. The walk back to the station was a lot less eventful, although I'd have preferred a map with slightly more detail than the whole city in 2x2 inches. The usual trick of checking that you're headed in the right direction by looking at the maps in bus stops also failed because for some reason they had taken away the detailed maps from every stop I passed leaving only a large map with less detail than my own. Other than that, it was quite uneventful, I got some good exercise and was back at my place by 1:30.

Saturday I met up with a couple of friends and went to Bof day and was quite impressed by the turnout at the opensolaris bof. For some time I've been talking to a friend about starting a DK OSUG, but we were still in the early planning stages because Solaris isn't all that widely used in Denmark and most of the opensource activities in the Copenhagen area seems to be either Linux or BSD. The turnout at the bof and the enthusiasm and curiosity displayed by the people there has made us rethink the whole thing and we've started looking at the possibility of doing an evening with a couple of introductory presentations and a sort of installfest. Watch this space and announcements going to for more details. The bof day also had sessions about virtualisation and tuning of live systems where we got to talk even more about opensolaris.
