NFS a Remote File System on Solaris

You must be logged into Solaris as the root user account.

The syntax to mount a remote file system using NFS is as follows:

mount -F nfs <remote file system> <mount point>

The following example will mount the file system /share2 located on the host cartman to the mount point /cartman:

<b>mount -F nfs cartman:/share2 /cartman</b>

How to mount a CD ROM in Solaris

Determine the name of the device by entering the following command:

   ls -al /dev/sr* |awk '{print "/" $11}'

This command returns the name of the CD-ROM device. In this example, the command returns the string /dev/dsk/c0t6d0s2.

Enter the following commands to mount the CD-ROM:

   mkdir -p /cdrom/unnamed_cdrom
   mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom/unnamed_cdrom

where /dev/dsk/c0t6d0s2 represents the name of the device that was returned in the preceding step and /cdrom/unnamed_cdrom represents the CD-ROM 3 mount directory.

Simple Logging in Perl

Set a Logging Variable

my $logging=1

Conditionally Open and Close the Logfile

At the earliest reasonable time, open the logfile in append mode:

if($logging){open FILE , ">>./my.log";}

At the latest possible time, close the logfile

if($logging){close FILE};

Don't
forget to close the logfile as part of your error handling routines as
well. Perl cleans things up nicely for you, but there are always
exceptions to those kinds of rules.

Logging Subroutine

A simple subroutine to enable logging as follows:

sub logit{
  if ($logging){
        print FILE "$_[0]\n";
  }
}

It
prints whatever it receives in the first parameter to the log file. If
you need to print something simple, just call "logit('text to log');"
and your log entry will be created.

C++ Convert string to upper/lower case

To convert an std::string to upper case you can use the following:

#include <algorithm>
#include <string>
…
std::string data = “Abc”;
std::transform(data.begin(), data.end(),
data.begin(), ::toupper);

For converting to lower case, you need to replace ::toupper with ::tolower.

Why is Microsoft running ads for BING via Google ??????

While watching Top Gear today I stumbled onto something rather "special" as I would like to call it.

Its an ad for Microsofts new search engine "Bing" on Youtube which is owned by Google.

The situation is special in more than one way though if you really think about it.

A. Microsoft is trying to gain visibility via a source it knows is used my most people. So by displaying an ad there most earthlings like me who use various services of Google get to know that there exists something called Bing.

B. Google gets nothing by displaying the ad (assuming its under AdSense sort of arrangement) unless someone clicks on the advertisement. So this means that if Microsofts Bing is not popular enough and most people do not click its ad, Google will not generate revenue which is the sole purpose for Googles interest in displaying ads.

C. If people start clicking on ads for Bing via Google, then Google will generate revenue for itself at the cost of losing people who may potentially like Bing and may possibly start using it actively ditching Google.

So should Google display ads for Microsoft ?
Should Microsoft display ads on Google ?

I don't know .. but its sure that things like these keep the humor going.

How to Enable or Disable a processor in Sun Solaris

In multiprocessor environments, Sun Solaris can allow enabling or
disabling Processors. This although is not something that we would do
all the time but can come handy when troubleshooting hardware issues.

Sun
Solaris has the psradm utility which allows enabling or disabling a
Processor on the system. The psradm utility changes the operational
status of processors. The legal states for the processor are on-line,
offline, spare, Faulted, and no-intr. An online processor processes
LWPs (lightweight  processes) and can be interrupted by I/O devices in
the system.

To enable or disable
a processor on the system we need to know the Processor ID. This can be
found using the psrinfo utility as follows:

sunsolaris# psrinfo
0       on-line   since 05/09/2008 19:41:32

where 0 is the processor ID.

To know the path of the psradm command

sunsolaris# which psradm
/usr/sbin/psradm

To disable a processor

sunsolaris# psradm -f 0

where ‘0′ is the processor ID and ‘-f’ indicates the processor is taken offline (disable)

To enable a processor

sunsolaris# psradm -n 0

where ‘0′ is the processor ID and ‘-n’ indicates the processor is brought online (enable)

Review: Angels and Demons

http://www.imdb.com/title/tt0808151/

Well I went to watch this movie today. Having read the book 4 times I come to the conclusion that it wasn't what Dan Brown wrote. The story was changed quite a bit to adapt it for the screen. However I liked the movie.

I know people are going to judge the movie based on the book but if you watch the movie from a standpoint where you don't expect whats in the book to happen and let the story unfold its a good watch. The story made sense and the reinterpretation of events from the book was fluent. However I would have loved it if they kept it the same way and made an 8-10 hr movie covering everything.

The major reason I wanted to watch this movie was to get a sense of vatican architecture which is covered extensively in the book. I thought the filming of churches was good and presented the sense of grandeur which I imagined through the eyes of the book having never been there. I do have a wish now to visit vatican. The acting was fine and not the best i've seen. I think the hassasins character was a bit week than whats in the book and could have been a potential improvement. Also CERN should have been covered in more detail which I was actually looking forward to.

Anyways I cannot say that the movie did justice to the book but I can say it was an above average effort. I'd highly recommend the book though to all the people whether they have watched the movie or not.

Extract files from a Solaris 10 .pkg Package

To extract the files just use this

mkdir tmp

pkgtrans pkgfile tmp

All the files will be extracted without any package installation


Readd files

pkgtrans -s /tmp /tmp/name.pkg

Add and change a default route in Solaris 10

Add a default route (gateway).

Create an /etc/defaultrouter file with the IP to have it set to this for each boot.

route add default xxx.xxx.xxx.xxx

Change the default route

Step 1: edit /etc/defaultrouter

Using the editor of your choice, edit the file /etc/defaultrouter — the only line in the file should be the default route of the system, for example: 192.168.1.1. This change will not take effect until the system is rebooted.

Step 2: Delete the current default route

To make the route change take effect immediately, you must first delete the default route. If the current default route is 192.168.254.1, then the command would be:

route delete default 192.168.254.1

Step 3: Assign the current default route

To implement the new default route without rebooting the system, use the following command substituting your default route for 192.168.1.1:

route add default 192.168.1.1

Photographic Evidence of Mac OS X Leopard on my HP Laptop

Here is the photographic evidence of my latest hack.

After brutal killings of my boot sector, multiple rounds of saves by ubuntu live CD and Vista DVD, several partitioning plans that failed to work, in-depth encounters with Grub, NTLDR and Darwin, inspiration drawn by Wozniak and 2 sleepless nights later, I managed to install Macintosh OS X 10.5.6 Leopard on my HP laptop.

Now I am the happy owner of a laptop with

Windows Vista 32-bit
Windows 7 64 bit
Ubuntu 9.04 32 bit
Machintosh OS X 10.5.6 Leopard

all working in harmony with three bootloaders greeting me when I start my machine.

Eye candy :)











The battery info in OS X gives the final proof of the fact that its indeed a hacked install and not an painted linux install which I have tried and it comes very close to the real thing.
