In my previous write up here, I wrote a brief description of the Sun VTS (Validation and Test Suite) which can help one to run tests on any Sun Supported hardware and hardware components and report the health status and identify faulty devices. Now, lets get installing and run Sun VTS in Solaris 10.

SunVTS, Sun Validation Test Suite, tests and validates Sun hardware by verifying the configuration and functionality of hardware controllers, devices, and platforms. SunVTS is used to ensure a “clean bill of health” of the overall system under test and its underlying hardware. Several diagnosability features incorporated in the latest release makes SunVTS an effective online/offline diagnostics tool. The added emphasis on failed FRU (field replaceable unit) identification, and data safe, low impact testing, makes it appropriate for use online and offline in ant environments.

SunVTS supports a flexible interface that allows a user to remotely schedule and monitor anything from a single test on a single piece of hardware to multiple instances of multiple tests in order to fully stress the system. SunVTS runs on all Sun SPARC based platforms supporting Solaris 2.5 or later releases. SunVTS also runs on many Sun x86 based platforms supporting Solaris 10 or later.

The nscd daemon is a caching daemon in Sun Solaris. It provides caching services for hosts,passwd,group,ipnodes databases using various nameservice lookups like hosts file, DNS, NIS,NIS+ and more. Each cache has a separate time-to-live for its data and modifying the local database like /etc/hosts invalidates that cache within ten seconds. nscd doesn’t cache /etc/shadow (contains encrypted passwords for /etc/passwd) file simple for security reasons as anyone would understand.

As nscd daemon provides caching service, it is necessary when you run a name service like DNS, NIS or NIS+ in your network. The configuration of nscd daemon can customised using the /etc/nscd.conf file and it is important more from a security point of view where you can control what is and how is cached on your solaris server.

Network File System (NFS) security in Sun Solaris can be enhanced by restricting the source ports for the client connections for NFS to be only privileged ports. The privileged port range is from 512 to 1023. Enabling this security feature for NFS in solaris, checks if the source ports from the clients from privilege ports. This prevents malicious users from gaining access to files exported/shared by the NFS server by preventing custom RPC based scripts or applications being used on unprivileged ports.

I discussed here about resetting the password on Sun Solaris Operating system in SPARC platform. While the procedure is almost the same wherein you boot with the CD into single user mode and mount the root partition, here we discuss the procedure to reset the password for the root user on the x86 platform.

It is recommeded that the security for the physical access to the server is restricted so as to ensure that there is no unauthorized access and anyone who follows this routine is an authorized personnel.

There is every little chance that one loses or rather forgets the root password of his Sun Solaris servers. In the event, this happens, there is a way out of it. Well the way and infact the only way is to reset the password as there is no way to recover it. Recovering/restting the password involves booting the server in Single User mode and mounting the root file system.

As you are aware of, every Operating System has a Hardware Compatibility List (HCL). The Hardware Compatibility List (HCL) identifies hardware that is compatible with the Operating System and provides information about available software support.

Hardware Compatibility List (HCL) for Solaris 10 OS:

http://www.sun.com/bigadmin/hcl/data/sol/

There are totally 906 system which includes OEM & System Vendor Products, VMWare,Servers, Desktops, Laptops andMotherboards and 1568 system components

Hardware Compatibility List (HCL) for Solaris Express Developer Edition:

This includes 975 Systems and 1602 system components

The Sun Device Detection Tool can help you to determine if the Devices on the system is detected by the Sun Solaris Operating System.
If your device or system is already on the Hardware Compatibility List (HCL) then this may not be necessary. Click here for the HCL in Sun Solaris.

However, there is no harm in running the tool. The tool also allows you to submit the device to HCL under the Reported to Work Function (RWF).

Solaris Operating System for x86 Installation Check Tool checks the system on which you try to install the operating system and report if the system can run the Sun solaris OS properly.
The download is a simple ISO file which then needs to burnt onto a CD to create a boot CD. Once created, start the X86 system with the CD. The ISO can be downloaded from here.

For Sun Solaris Express Edition, click here
