Solaris Infiniband Update 2
Monday, July 14. 2008
An important update for the Infiniband Stack in Solaris was released yesterday. Josh Simons reports in his blog:
Yesterday, the Sun InfiniBand engineering team released Solaris 10 driver support for ConnectX (a.k.a. Hermon), the latest generation of InfiniBand silicon from Mellanox.[...]In addition to the driver, the update also includes a new flash updating tool for ConnectX, a uDAPL update, and several additional components, all of which is described in the documentation.You can get Solaris Infiniband Update 2 at the usual location ...
Get rid of root - or: PSARC/2008/321
Wednesday, July 9. 2008
An interesting PSARC case got it´s approval: PSARC/2008/321 - No Root Login:
Besides of making root a role, this would be another way to get rid of a direct usable root account in Solaris. With this change you can use your own username and password to log into an "root shell" without knowing the root password ... there doesn´t even have to be a root password. You only need the authorization
(via ceri on twitter)
It has been suggested that Solaris should permit "root" to be a no login account.
[...]
Add a "solaris.system.maintenance" authorization. Modify sulogin(1M) toprompt for a username and password. If the username entered is authenticated by the password and has the "solaris.system.maintenance" authorization, enter system maintenance mode. If not, as before this project, deny access.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 15: Using flash archives for recovery
Friday, July 4. 2008
You can´t use flash without any further thinking for system recovery. As i wrote before, the new system is cloned and has a new personality, it´s not a copy. But there is a trick.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 14: Using flash archives
Friday, July 4. 2008
As i stated before, the installation mechanism of Jumpstart Flash is quite different from a normal installation. So i will start with a new template on a new server to demonstrate Jumpstart Flash.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 13: Deep dive to post installation
Friday, July 4. 2008
As i told you before much of the configuration takes place after the installation executed by the orignal Jumpstart mechanism. We used several modules of the JET toolkit so far, thus this is a good moment to do a deep dive into the process that takes place after the normal Jumpstart installation.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 12: Automatic hardening with SST
Friday, July 4. 2008
It´s a best practice to harden a system before you place it into your production network to reduce possible attack vectors. Sun developed the Solaris Security Toolkit for this task to collect all the knowledge about hardening Solaris in a tool thats simple to use. I´ve wrote already about the usage of the toolkit in another installment of the LessKnownSolarisFeatures series.
It would be really neat to have an automatized hardening of new systems. The Jumpstart Enterprise Toolkit can do exactly this with the help of

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 11: Mirrored boot disks
Friday, July 4. 2008
Okay, in enterprise computing you wouldn´t use a system without redundant boot disks (at least, when you haven´t an application that can survive a loss of computing nodes without a problem). So it would be nice to automatically configure a mirror of the boot disks with the Solaris Volume Manager. I assume in the following part, that you have a working knowledge with the SVM. When this not the case, it isn´t really a big problem, as this part it somewhat selfexplaining when you are aware of the concept of RAID.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 10: A polished basic installation
Friday, July 4. 2008
Okay, now we´ve done a basic installation. But mostly we do a standard set of customizations on every system we touch, like installing a few essential tools or integrating the actual recommended patch cluster. So we want to polish the standard installation a little bit. We will extend a basic Solaris 10 Update 5 installation with the following items:
- installing the SMCjoe package
- nstalling the recommended Patch Cluster
- configuring the Secure-by-default mechanism to limited

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 9: Basic installation of a new system
Friday, July 4. 2008
At first we will do a really basic install. No tricks, just the pure operating system. Nevertheless this part will be a little bit longer as i will do a technical deep-dive into the process of installation in this example to show you the inner workings of JET with this installation as an example.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 8: Preparing the first installation
Friday, July 4. 2008
Now you have to copy your Solaris install media. Obviously you need the Solaris files before you can install them to a system via network. You can do this on two ways.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 6: Prerequisites
Friday, July 4. 2008
Okay, before working with the Jumpstart Enterprise Toolkit we have to prepare some stuff. We need systems, a network (as fast as possible to reduce installation time, but even 10 MBit/s would suffice), operating system ISOs etc.

Less Known Solaris features: Jumpstart Enterprise Toolkit - Part 5: The toolkit
Friday, July 4. 2008
Now we get to the tool that will be the centerpoint of the whole tutorial: The Jumpstart Enterprise Toolkit. This tool was started as an internal tool by some project engineers to make their job easier. And with the time a really mighty tool was born.
