After searching for hours for the ASRock on board vga drivers by the wrong name "755vm800" I finally found the drivers at
ASRock -> Download
So yea, great accomplishment. :)

lost.... libgcc
What a quest.... the hunt for libgcc on solaris 10. The problem was to find if Solaris 10 ships with libgcc. Now anyone else would know that on top of their head, but not me! I have to make everything a challenge.
So I found the package listing for Solaris 10 sparc and x86 at
http://docs.sun.com/app/docs/doc/819-6399/6n8droaea?a=view Sparc
http://docs.sun.com/app/docs/doc/819-6399/6n8droaec?a=view x86.
that showed that gccruntime was included in the standard packages. However, that wasnt enough. I had to confirm that libgcc was part of the gccruntime. So I tried
pkginfo SUNWgccruntime
with no luck. Then my coworker suggested to get the vmware image and do a pkgadd or pkgrm and find out. So I could get around that when my system permitted (faced lot more problems before I could get the vmware running). Once I had the vmware I did a pkgrm SUNWgccruntime and it showed removing libgcc.so.
Which I believe confirms that libgcc is part of gcc runtime files.

I am in control
Hehe.. for the psychologists out there, the subject is not a statement of analysis of my mental state. Its more of the tool i've been searching for for a while and just couldn't remember what it was called or what to search for. Until, my co-worker said he had used it before and to search the web for "sourceforge keyboard mouse". And I got the link that I was looking for a while.

#Hack 4 Creating a Persistent Daemon with init
Make sure that your process stays up, no matter what
There are a number of scripts that will automatically restart a
process if it exits unexpectedly. Perhaps the simplest is something
like:
$ while : ; do echo "Run some code here..."; sleep 1; done
If you run a foreground process in place of that echo line, then the
process is always guaranteed to be running (or, at least, it will try
to run). The : simply makes the while always execute (and is more
efficient than running /bin/true, as it doesn't have to spawn an
external command on each iteration). Definitely do not run a
background process in place of the echo, unless you enjoy filling up
your process table (as the while will then spawn your command as many
times as it can, one every second). But as far as cool hacks go, the
while approach is fairly lacking in functionality.
What happens if your command runs into an abnormal condition? If it
exits immediately, then it will retry every second, without giving any
indication that there is a problem (unless the process has its own
logging system or uses syslog). It might make sense to have something
watch the process, and stop trying to respawn it if it returns too
quickly after a few tries.
There is a utility already present on every Linux system that will do
this automatically for you: init. The same program that brings up the
system and sets up your terminals is perfectly suited for making sure
that programs are always running. In fact, that is its primary job.
You can add arbitrary lines to /etc/inittab specifying programs you'd
like init to watch for you:
zz:12345:respawn:/usr/local/sbin/my_daemon
The inittab line consists of an arbitrary (but unique) two character
identification string (in this case, zz), followed by the runlevels
that this program should be run in, then the respawn keyword, and
finally the full path to the command. In the above example, as long as
my_daemon is configured to run in the foreground, init will respawn
another copy whenever it exits. After making changes to inittab, be
sure to send a HUP to init so it will reload its configuration. One
quick way to do this is:
# kill -HUP 1
If the command respawns too quickly, then init will postpone execution
for a while, to keep it from tying up too many resources. For example:
zz:12345:respawn:/bin/touch /tmp/timestamp
This will cause the file /tmp/timestamp to be touched several times a
second, until init decides that enough is enough. You should see this
message in /var/log/messages almost immediately:
Sep 8 11:28:23 catlin init: Id "zz" respawning too fast: disabled for 5 minutes
In five minutes, init will try to run the command again, and if it is
still respawning too quickly, it will disable it again.
Obviously, this method is fine for commands that need to run as root,
but what if you want your auto-respawning process to run as some other
user? That's no problem: use sudo:
zz:12345:respawn:/usr/bin/sudo -u rob /bin/touch /tmp/timestamp
Now that touch will run as rob, not as root. If you're trying these
commands as you read this, be sure to remove the existing
/tmp/timestamp before trying this sudo line. After sending a HUP to
init, take a look at the timestamp file:
rob@catlin:~# ls -al /tmp/timestamp
-rw-r--r-- 1 rob users 0 Sep 8 11:28 /tmp/timestamp
The two drawbacks to using init to run arbitrary daemons are that you
need to comment out the line in inittab if you need to bring the
daemon down (since it will just respawn if you kill it) and that only
root can add entries to inittab. But for keeping a process running
that simply must stay up no matter what, init does a great job.

another filesystem sshfs
Although I don't know enough about file systems to say how secure this is. But since its running on ssh, I am assuming its secure enough for my humble earthly file sharing. So I found sshfs while looking for alternative for smbfs as it really was giving me quite a bit of problems. Here are the steps involved in getting it working.
Firstly, it only needs to be installed on the guest system. i.e the system where you are going to mount to.
You will need the following packages.
fuse-2.6.1.tar.gz (if your OS is not compiled with fusefs support)
sshfs-fuse-1.7.tar.gz
Just the standard should do.
./configure
make
sudo make install
Once the above two packages are compiled and installed, we now need to set up the system. Follow the steps below:
First you need to load the fuse module into the system.
sudo modprobe fuse
lsmod should show you fuse to be loaded.
fuse creates a device /dev/fuse on the system. Change the permissions on this device to allow read/write/execute as you see fit.
sudo chmod user:group /dev/fuse
Now you can create a local directory where the host OS will be mounted. I keep my smb mounts and sshmounts in /SHARES
mkdir /SHARES/hostname
Now you can mount the host system using sshfs
$sshfs -h
usage: sshfs [user@]host:[dir] mountpoint [options]
sshfs rohan@gandalf:~/sources /SHARES/gandalf
I would suggest to take a look at sshfs -h. It has a lot of options that can be configured.
Note: I had the error below when I tried to run sshfs
"check /etc/ld.so.conf for a line containing '/usr/local/lib'. If it's missing, add it, and run ldconfig afterwards." at

Firstly, it only needs to be installed on the guest system. i.e the system where you are going to mount to.
You will need the following packages.
fuse-2.6.1.tar.gz (if your OS is not compiled with fusefs support)
sshfs-fuse-1.7.tar.gz
Just the standard should do.
./configure
make
sudo make install
Once the above two packages are compiled and installed, we now need to set up the system. Follow the steps below:
First you need to load the fuse module into the system.
sudo modprobe fuse
lsmod should show you fuse to be loaded.
fuse creates a device /dev/fuse on the system. Change the permissions on this device to allow read/write/execute as you see fit.
sudo chmod user:group /dev/fuse
Now you can create a local directory where the host OS will be mounted. I keep my smb mounts and sshmounts in /SHARES
mkdir /SHARES/hostname
Now you can mount the host system using sshfs
$sshfs -h
usage: sshfs [user@]host:[dir] mountpoint [options]
sshfs rohan@gandalf:~/sources /SHARES/gandalf
I would suggest to take a look at sshfs -h. It has a lot of options that can be configured.
Note: I had the error below when I tried to run sshfs
foofs: error while loading shared libraries: libfuse.so.2:I found the solution
cannot open shared object file: No such file or directory

installers on os's
Alright.. so, trivial for a lot of people, but jsut so I dont forget the usage here are the different installers in different OS
linux: rpm
rpm -ivh pkg.rpm #install an rpm package
rpm -qa | grep pkg #search for a package
rpm -e `rpm -qa | grep pkg` # erase a given package... use with care .. grep may matche more than one package..
hp-ux: swinstall
swinstall -s source.depot pkgname #install pkgname form the source.depot
swinstall -s source.depot.gz pkgname #also deals with gz archive
solaris: pkg-*
pkg-add -d #add a package
pkg-rem # remove the package
grrrr forgot already... memory is just not my thing...
debian: apt-get
apt-get install "exact name"
okay will update when i find the right info...
linux: rpm
rpm -ivh pkg.rpm #install an rpm package
rpm -qa | grep pkg #search for a package
rpm -e `rpm -qa | grep pkg` # erase a given package... use with care .. grep may matche more than one package..
hp-ux: swinstall
swinstall -s source.depot pkgname #install pkgname form the source.depot
swinstall -s source.depot.gz pkgname #also deals with gz archive
solaris: pkg-*
pkg-add -d
pkg-rem
grrrr forgot already... memory is just not my thing...
debian: apt-get

time and again
I was listening to a gazal, "Woh kagaz ki kashti". An excellent gazal, and i heard the line
"Na Duniya Ka Gham Tha Na Rishton Ke Bandhan
Badi Khoobsoorat Thi Wo Zindgaani"
and that made me think (I won't say realize, as i believe you really don't know when you realize), Where I stand. Where I was, where I will be. To elaborate, I am probably in a situation where I am understanding relationships. Their value. How its hard to keep ties. Life's been great to me so far, but why does it have to make me choose? Why do I need to be in a position where I will hurt someone or another? Why can't we all just get along? Being in a position to make a decision is bad, well probably not as bad as not having right to make decisions. And then I think, how great it was to be young, small, little!! Had no worries, didn't need to worry about keeping everyone happy. And thats exactly what the song fits in.
I've always loved gazals, and felt them. Felt them, to my experiences. And after hearing a gazal for years, suddenly, someday, I see the beauty in them that I missed out every time I heard it. Like the line I quoted above. Didn't mean much to me. Well, I liked it. Nothing too exceptional, until while driving home from our Christmas party it struck me. Beautiful! And that led me to write.
Its funny, how I feel grown up. Grown up. Those words resonate. And make me think, how this is absolute nothing compared to what others face. What I am going to be facing some day. I am doing what I think is the right thing for me to do now. Prepare for that time when I will be in a crises. Lucky, as I consider myself (lucky enough to hope for a Jack of Hearts on the last card in poker and get it :).. yes DAMN I rock.. Okay, tad bit of my self there) to have not been in any situation that I consider taxing my emotions. I believe I have lived a very sheltered life. Sheltered by luck. I believe I will some day be in a situation where I will breakdown. What does one do to prepare oneself? I was, and am again (with a short break in between), a risk taker with a plan for worst case. So whats the worst case that life's going to throw at me? And how will I take it? How do I prepare myself for that? Practically, I think there is no point worrying about it till its there. And then deal with it whole heartedly.
I don't know what am I. I've always thought I know myself. Been confident and believed myself. Trusted myself over anyone else, and had complete faith in my decisions. But.. now I begin to "realize". I am not bigger than life. I understand what they would mean when they would say that.
Ego. I, apparently have a huge ego. But where is the line between Ego and Confidence? I dont mean confidence in oneself. Confidence to show, is what i mean. A little of show is needed to get anywhere. Sales is the key. And confidence is the first and foremost aspect of that. But how do I curb the ego leave the confidence intact?
Guess, on the whole, this post doesn't really appear to make much sense. But an trained mind will tell you that this really doest. :) Well, things that have been on my mind are out there. If any one can answer the questions that I didn't ask, I'd like to hear it. Although, comming back to my ego. I really don't think that there are many people out their that are better than me. So that would mean, I don't think many people can guide me. That lead me to ever really go to many classes in high school, lectures in university, T.A's at university.
Now atleast I am willing to accept that there is intelligence out that thats higher than mine. And I think thats a good start.
Dil-e-nadaan tujhe hua kya hai
Just a song I like. I love ghazals. To the extent I have may be 2-3 CD's I've bought with multiple songs repeated. Just so that I can have all the ones I like in the best quality in one place! Bad Excuse? Love knows no reason. Sorry.

eth0 has different MAC address than expected, ignoring.
So following my previous post where I got kernel 2.6.9 finally running on my desktop, I had problem with eth interface.
Error said "eth0 has different MAC address than expected, ignoring."
So google search gave me some things that I treid and failed. One thing that worked was a nice link on how to spoof your mac address.
http://whoozoo.co.uk/mac-spoof-linux.htm
In summary:
1. set bootproto=none
2. ifconfig down eth0 (if it isnt already down)
3. ifconfig eth0 hw ether 11:22:33:11:22:22 (your choosen mac address)
4. service network restart
5. now you can go back and set the bootproto to dhcp
(Although step 1 and 5 don't make sense. I dont want to go back and narrow it all down right now. Have some deadlines to meet and so needed this pc running with 2.6.9 asap. Will update later, hopefilly :))

kernel woos
Alright, so I have compiled the linux kernel 32485902483 times, and failed. Big deal! So I took it upon my hands to explore this uncharted territory that I've always feared.
Okay now I am too bored to continue giving a background and how I sucked at that for last 3 years. Lets jump right to the point.
The problems I faced and solutions are below. All though you can search the same error string on google and get the same results that i am posting (thats what I did :)).
linux 2.6.19:
error: kernel panic saying "enforcing enabled but no policies"
fix: disable enforcing. add enforcing=0 in /boot/grub/grub.conf at the end of the line "kernel..."
linux 2.6.9:
kernel panic:
Cannot open root device "LABEL=/" or unknown-block(0,0)
fix: this has lots of fixes covered at
http://www.linuxquestions.org/questions/showthread.php?t=269230
What worked for me was increasing my block dev ramsize! Apparently sometimes ramdisk is too small for initrd to fit in (or so I understand). So solution,
grep BLK_DEV_RAM /usr/src/linux/.config
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_SIZE=8192
Add the above 2 lines to your kernel config.
