#!/bin/ubergoonz -x: it looks good ... http://sun.com revamp
a few weeks after I complained abt the revamped sunsolve search tool. it have improved a lot!
it would be doing the developers dis-services if I did not withdraw my complains.
A great thanks to the developers! great work!

Installing OS over the network - part 1
It seems like more major Operating System (OS) vendors are providing various method of installing their flavour of Operating Systems onto systems via the network. It is somewhat confusing with the different terms it was used and how it work. Here's a quick note on network OS installation on some OS that I am familiar with.
Vendor: Sun Microsystem
OS: Solaris Status: Current version --> Solaris 10
Framework : Jumpstart
Network Protocol used: Bootparam, TFTP, DHCP, NIS, NFS, HTTP
Boot Media: Network booting via OBP, CDROM, DVDROM
Vendor: RedHat
OS: RHEL
Status: Current version --> RHEL 4
Framework: Kickstart
Network Protocols used: HTTP, DHCP, NFS, TFTP, PXE,
Boot Media: Network booting via PXE, CDROM, DVDROM, Floppy
Vendor: NeXT
OS: NeXTSTEP/OPENSTEP
Status: defunct
Framework: Network install ??
Network protocols used: bootp, nibootpd, nibootparam, NFS, netinfo
Boot Media: Floppy, CDROM
Vendor: Apple
OS: Current version --> MacOSX 10.4
Framwork: NetBoot
Network Protocols used: TFTP, DHCP, NFS, DNS
Boot Media: Open Firmware, CDROM, DVDROM
more details wll follow on each network install technologies ... when i grep some time.

it looks good ... http://sun.com revamp
If you have noticed ... Sun have just revamp their website. The new website is way too cool (the look) ... if using a correct browser.....
I have always told my wife when it comes to condo's ads. fancy resturant served food ..
"They looks good".
Yes. They really looks good. atrist impression ..
But it is darn buggy!! The worst website revamp that Sun have ever done I would say. (dun belive? check the The history
for a moment, I thought it only happens to IE on windows (cos I was using form the office) ... then when i try that at home .. it's the same thing ..
:(
(BIG BOO)
I tried searching for OBP level matrix for various Sun h/w platforms on Sunsolve to create a script to validate the firmware level ... but when I tried to click on page 2 of the search result ...
Here's the screen shopts of how it looked ...
On a windows's IE
and on a Mac's Safari
...

The Strange New World of the SolarisTM 10 Service Management Facility
read abt it , The Strange New World of the SolarisTM 10 Service Management Facility, .. brand new way to managed startup scripts ..
sorta like RHEL's chkconfig / service command.
IMOHO, I like the way the SMF works like the wat linux manages the startup scripts.
Som BSD schoool of thoughts perople like the rc.local method of startup services and daemons on UNIX. But I prefer the SysV way.
NEVER MEDDLE WITH BULK THINGS.
modular. objected oriented. that's the way I like it. easier to troubleshoot and manage of cos.

RHEL 4 launch in Singapore
gotten myself some time off to leave office earlier to attend a RHEL 4 launch today, and I must remember to tell myself "never to attend one of such product launch talk again".
I wont mind going to MacWorld Expo
Good lesson learned.
not that I have anything against RH. No! I love RH. In fact, I started my unix/linux venture with Rh5.1. It is redhat that made me be able to learn and have real hands-on on Linux(and later unix).
but such product launch ... is really too marketing .. a total waste of time for any unix SA to attend.
(now .. it may be a good excuse to attend one if it covers the whole day during office hours).
One thing cool may be the free beers after the talks, but too bad the beer pump is way too slow, and and the beer queue is way too long. I did a slapslick joke on the beer pump being slow (it slow because it's not running on an 2.6 kernel).. and invited unfriendly stares .... gosh .. I think there are many w|nd0ws people around, or no one understands what I am talking about!
But one thing I learned is the SELinux feature is gonnna be available on RHEL 4. That should be cool! Great stuffs if the RHEL installed server to be used in an amberzone server.

The network is the computer
I am extremely disappointed with the support from a vendor for the past few weeks.
The OS is reporting ECC memory, but correctable ones that it.
As a diligent SA that I am. I logged in a service call. As there isn't any service distruptions (yet), I did not pressed on like I was from the past.
The error message persists and many alerts were triggered on the monitoring software, causing much alarm for the rest of the SA.
It went off for a few days, and while the vendor called, I told them maybe we can closed for now as they did not give any constructive solutions nor being proactive as I hope them to be.
then a few days later, the error keep comming back. triggering a lot of error messages!
This time round, I log in a service call with the vendor again. Guess what, all I have in response is their new DIMM replacement policy.
Nothing constructive. I mean if I was the vendor, I'd sugggest something to find out more details, instead of asking for data collection tools only.
I would have request the user to run some diagnostics tool. extended POST maybe, of Validation Test maybe?
oh hell no .. all I have is the pdf file of DIMM replacement policy.
If you are a SA, you will know that it doesn't thrills a least bit to know your vendor's DIMM replacement policy.
All I want is availability and performance!! By all means give me something constructive!
anyway, I requested some down time from my user, shut the box down. setted up extended diags and ran a full POST.
AH AH! 1 bank of memory was blacklisted!
the server booted up with 1GB ram less.
let see how long they take to response to this ....
gold support contract .....
*mutters*
guess i better study harder to get my RHCE.

du & df inconsistency???
I am extremely puzzled that du and df inconsistency.
I know that open files will be hogging the filesystem, and df will report it as being used. but strangely, lsof / did not show anything!
nevertheless, the df command is being used for the monitoring, as such many alerts were reported in the monitoring tool.
I logged on and did some checks. upon checking, it was found that many process is hogging onto the filesystem. by grace of fuser -cu / .
I did a for loop to check on it. using ptree, pfiles with the output of fuser and found that a particular processes (hundreds of them !) is hogging the filesystem ...
hmm ... does runing process using the filesystem is hogging the filesystem?
it looks like the filesystem is meant to be an application homedirectory, and logging to it .. users are extreme inclined to run tail -f on it very much. ....
*mutters*
does that caused the df output to be high? (will find out ..)
i wonders ....

MacWorld Expo 2005 San Fran
Whohoooo .. just finished viewing the MacWorld Expo 2005 SanFran Keynote. Amazing new products from Apple again.
I like the iWork product very much! Especially the Pages application which is a word processor. I have been using a lot of Words in my daily course of work for documentating. Sure hope to be able to use that as my daily work as well. It looks amazing solid!
My Jedi master wonders if the new Pages from iWork is the same as Pages.app in NexTSTEP. hmm.. I wonder too.. used that on OPENSTEP before. and it's pretty cool.
The new Mac Mini rocks! The size of a shoe box? well, it's packed with enuff power for my daily email, web surfing and chat.
I wonder if the Mac mini would scaled up as a cool firewall. Sure hope to have bunch of em. geat to use them in a grid computing evnironment. Normal Intel Blades servers are way too bulky!
Finally! I love the iPod Shuffle. A thumbdrive size player, that integrates with my Mac, and great to use when jogging! :)

cd /net
A few months ago, i did a `find -type=job /net`as I felt that after working for almost 5 years in a same envrionment, I am begining to feel tired and tunnel vision`ed at the things that I did.
many people at my old workplaces loves and think that i am a good SA. i get compliments all the times. but i have been feeling doubts at myself.
The main reason that I could think of why people compliments me "i understand the environment very well".
My old work place is my first real UNIX SA job. (earlier jobs also deals with UNIX and a lot of Sun Hardware) It's a lovely place with lovely technology and lovely people. Many things I have learned from there, helped shaped me as a better unix SA, if not, a better person.
It's such sweet sorrows that I felt having to part all these, after 5 years of fond memories. But life goes on. I look forward for new challanges.
I wonder if my skillsets is still relevant at the new place that I will be working in.
But the answer will be know pretty soon.
Once this week of in-between-jobs holiday is over.
aggrhhh ... GOSH! I haven't had a root shell for days! I am having root access withdrawal!

No More Mdm Wong! It's Mr Wang manz!

1st working day in 2005
started the 1st day by going through the mails, reading the systems alerts over the weekend. Lucky nuthing much happen. (finger crossed) ...
Then I saw this mail from HR showing this URL, which i think is very useful http://www.humandynamic.com/hdaptimes/times_Trauma.htm in light of the recent natural disaster, tsunami.
I need this earlier if not I won't have insomia last night.
A few collegue suggested to pool up some money ($10 each) to bet in the TOTO draw and I was tasks as the implementor to place the betting. Too bad we did not win anything. If not, i would most glad to donate portions of my winnings to Red Cross and spend the rest to Mac World Expo
