backup-sms.sh

I always have the feeling that huge sms.db will slow down SMS application startup. So I created a script to be run in Terminal and I wish I can do an application for this.

Aperture: A tiny thing that saves a lot of time.

Just for expressing an excitement. A new thing I just discovered and love about Aperture.

I have a lot of pictures and my last trip to Langkawi produced more than 1700 shots - and my mother wants them ALL! So as I started to export hundreds of pictures, I went through one by one to reject bad photos - even the exporting is still running (right now). Suddenly I came to a photo that attracts me. After a simple edit, I decided to upload it to Flickr and this is the good part. I don't have to wait for the earlier exporting process to complete before exporting a new picture. It really saves my time.

What a good software design in customer point of view!

Intrepid On Acer Aspire 4720

Previous day, I had setup the latest Ubuntu on my sister's laptop. I
was surprised of how cool & beautiful Linux these days. It is even
easier to setup comparing to old days. I also compared Ubuntu with
Fedora Core 10 on my VirtualBox. I have to agree, I like pre-installed
Ubuntu better. Picasa also works great.

Now, with VirtualBox, she keep a copy of an uninfected Windows. She
still need it I for her iPod because iTunes doesn't work well with
Wine. But still a few issue she face - USB & Shared Folder in
VirtualBox.

Installing NTFS-3G on your Mac OS X will render your Windows drives invisible from your "Startup Disk" preference pane. [1] They suggested disabling or uninstalling to bring the disappeared drive back. But I accidentally see a Windows partition in my VMWare Virtual Machine Library.

Wth with my sort?

Leopard Re Installation: Part 2

I reformat using the same filesystem my external hard drive uses. Then set UID to 1000 in the System Preferences > Accounts > Advanced Options (right click on username). After that chown whole home directory.

Leopard Re Installation: Backup & Restore Issue

I wanted to replace my OS X Server because of lack of Internet Sharing feature. So I do both Time Machine backup and manual backup before making a fresh OS X installation. These are the issue that I faced.

Restoring using Time Machine right after Leopard Installation is not as I expected. There will be folders like 'System (from old mac)', 'Applications (from old mac)'. For me, this is not neat.

Your OSX filesystem must have the same format as your Time Machine backup filesystem. I'm using HFS Journaled with Case Sensitive, but my external hard disk is using HFS Journaled NOT with Case Sensitive. I have to reformat either my OS X partition, or my external hard disk.

Restoring files from Time Machine is strict because of UID. My user uses 501 as UID but my last Server system was using 1000 as UID. So restoring could get complicated.

Right now I'm going to change my UID and reboot and see what will happen.

Shell Auto-completion

I feel it is too late for me to realize that auto-completion using ESCAPE ESCAPE is actually came from a shell variable, $EDITOR

stty kill ^U
stty intr ^C

Be Gentle With Your Keyboard

I just learn that, (after years of facing terminal), the more you minimize your typing mistakes, lesser the potential of screwing up or end up your work dissatisfied. It helps me thinking better too.

Think before you type. Think again before you press enter. Avoid typing too fast (because there are kids who think typing fast shows that they're good). Type slow not too slow, sit back and relax. Enjoy the cleanliness of your terminal output.

p/s: Yeah, I've worked with business critical environment... and I did screw up a few times :-p And this came to my mind while I was watching a 'really good' but not sys admin guy, typing neatly.

Unresponsive Dock and Finder

I can't access Dock just now. No respond. And I'm unable to go through Finder too, so I can't get a touch on Terminal. I forced quit some applications, but there's only TextEdit which I left because there's work which wasn't saved yet. Then how do I rescue this without force quitting the TextEdit which I'm not even sure if it is the cause of all this? But I'm pretty sure that it was about the hung Dock. I really wanted to avoid logging out or reboot.

But user fast switch is enabled. I logged in as administrator and used terminal to kill other's Dock process.

PS=`ps aux | awk '{if($1="amanyus") print}' | grep -i dock`; kill $PS

PS is temporary shell variable to hold a value. This value is coming from a ps command after few filtering with awk and grep. Awk only print lines that match the first column with user amanyus, which result in all amanyus' processes. Next with grep, only match insensitive case dock rather that all processes under user amanyus because we only want to find Dock process and put in the PS variable. Up to this point, PS variable will hold the process number of amanyus' Dock. After the semicolon, the process will be killed.

Silly is you just can simply use ps aux | grep amanyus | grep Dock and kill the Dock's process without bothering with awk command =p

p/s: Hey, I forgot about spotlight at the first time to search Terminal, but not sure if it would work.

The owner of my original home folder gave me a clue. They are all owned by directory admin. And I remember last time when I changed the Open Directory role to the Directory Master, we need to set password and verified it. There is also a username already written there as diradmin. So what I did is I set the role to standalone and set it back again to Directory Master. This time I replace the diradmin as my original account name. I backed up before commit to prevent any loss or the potential of my home folder be overwritten. Fortunately it doesn't. No files affected. The owner also automatically changed. And once again, the day is saved thanks to the powerpuff mac :-P

Screwed Up: Open Directory Part 2

amanyus:log root# host amanyus.puj52
;; connection timed out; no servers could be reached

After few smacks on the head lol, I played around with DNS service on the Server. I created a zone, named it and added machine record in it. That solved my problem.

amanyus:log root# nslookup amanyus.puj52
Server: 127.0.0.1
Address: 127.0.0.1#53

Name: amanyus.puj52
Address: 192.168.1.14

amanyus:log root# host amanyus.puj52
amanyus.puj52 has address 192.168.1.14


Since the DNS is clean, Kerberos finally running. But the my usual login still doesn't show up :-(

Screwed Up: Open Directory

Server is sucks when waking up from sleep. I suck too. Coz I made Server run on portables. I'm not sure of this but I think Open Directory or Kerberos service is affected by wake and sleep mechanism. There was time when my password doesn't work if I typed in immediately after the Server woke up.

Tonight something went wrong which I don't have any clue why. Failed to login even after few reboots. So I suspect the authentication system - which I'm not sure LDAP or Kerberos - might not running or maybe not even started. So I logged in as root and check the System Preferences where I found out that my usual account is gone. Now that really bothers me. I checked my home directory and fortunately it's there.

Server Admin show LDAP and Kerberos stopped. I've checked through numerous posts on the internet. There's one instruction that says to set the Open Directory role as standalone. I followed without knowing what I'm doing. And that is where I screwed up. I can't change back to the original role.

Now I have to figure out what the heck is happening. A lot messages in the logs like has got something to do with DNS. Hope someone tells me how to make the changeip happy.

amanyus:etc root# sudo changeip -checkhostname
Primary address = 192.168.1.12
Current HostName = amanyus.puj52
The DNS hostname is not available, please repair DNS and re-run this tool.

Insert installation disc. Open up terminal.


$ cd /Volumes/Mac\ OS\ X\ Server\ Install\ Disc/System/Installation/Packages/
$ open .

Run Essentials.pkg and install it to an empty filesystem or empty folder. the libphp.so will be inside [install_dir]/usr/libexec/apache2 directory.

Screwed Up: Apache2 & PHP Part 2

I went through tough times figuring out how. Google tried to help me but the results are meant for Leopard, not Server. I can't find any pre-compiled php for Server. I also tried to set CFLAGS and LDFLAGS as intruction for Leopard and the compilation failed.

At last I solve it with the Server Installation disc. But you can't find it simply by Finder. Even if you use Finder to look into the package contents, still you won't find the packages used to install all the Server components. I spawned up my terminal and go through the installation disc. There are a lot of packages and I have to install one by one on an empty filesystem so that I will know what each package for. And I found what package installs the libphp.so - the fix is in the next post.

It is fixed. What a relief.

Screwed Up: Apache2 & PHP

I screwed up. I overwritten pre-installed PHP on Server that cause problem for Apache startup. God help me.

Edit: I suspect that the libphp5.so not compiled to match the correctly architecture. So to make the apache running, I hashed out 2 lines that load php module inside /private/etc/apache2/httpd.conf. It runs but without php support. So localhost:80 show a nice Server webpage. I also notice that my computer automatically downloads a php source hehe. Because it is un-identifiable.

Size Comparison between TIFF, JPEG & PNG

These are file info for 3 images with different format. It occur to me when I was wondering which format have the best optimization for size, regardless of the quality. Grab application (in Utilities) save snapshots to a TIFF format. I agree Grab made for quality but in a web arena, size does matter. Bandwidth affect a lot of things. Web hosting limited bandwidth, download time and most importantly, our browser cache - performance. So why wait, create an automator plugin

For decoration only.

But it is a different case for screenshot shortcut key. By default it will automatically save to your Desktop as PNG format. Surprisingly, JPEG size is a lot better.

Access iPhone using Finder

First, make sure you have AFP installed on the iPhone - you need Installer. Turn on Airport on your Mac and create network from the airport icon menu. If the network is set, you'll see the airport icon changed. Set iPhone to join the network you just created. Take note of the iPhone IP address. On your mac, activate Finder. From the top menu, choose Go > Connect to Server. Type you iPhone IP address like this example. You will be prompt for login. Type 'root' as user, and 'alpine' for password. Choose Root's Home instead of Root Filesystem because the earlier has bigger disk space.

For what? iPhone as your wireless external disk drive.

Get Automated

Automator has been there since Tiger. I had a lot of Automator plugins on Tiger last time. The main goal of Automator is it can simplify repetitive work thus save you a lot of time.


I take digital photo experience as an example. When we take pictures using the digital camera, it normally save the file using a combination of letters and sequential number, right?


Let say we want to rename all image files so they will be more meaningful. Automator lets you rename all of them once without you rename each file one by one.


You can save every workflow you created as a plugin. Plugin can help you run workflow directly from your Finder so that you don't have to create the same workflow each time you come to a same task.

Infrared Apple Remote Does Work, FrontRow Can't Find iTunes Songs

Infrared remote is disabled by default on Server. You can find the option under Security section in System Preferences. Then you will discover that FrontRow would not be able to find songs in your iTunes. Thanks to appleguru1, he repackaged the original update and made it available for download.

If you want to backup your original files before upgrading, copy your:
/System/Library/CoreServices/Front Row.app
/System/Library/PrivateFrameworks/BackRow.framework
/System/Library/LaunchAgents/com.apple.RemoteUI.plist


Window minimize disabled. I wonder when Apple will solve this. It's been bugging me since Tiger.

Spotlight Doesn't Search a Thing

Open Terminal application (Application > Utilities > Terminal) and run this command:

sudo mdutil -a -i

This command will turn on indexing on all volumes except impossible volumes such as DVD volumes and unsupported filesystems volumes. mdutil command is a command to manage the metadata stores used by Spotlight. Every volumes are separated-ly managed. Means for example you can turn on indexing on /home only instead of all volumes.

You can check the status first before simply turning on by running this command:

sudo mdutil -a -s

There is a good side for enabling indexing on few Volumes. It will narrow down search with the area that we want. Definitely we don't have to go through / to search documents in /Volumes/ExternalDisk.

PS: Volumes is not mount points. Volumes can be seen on your desktop. The hard disk icon, Macintosh HD is a volume.

Once you turn on indexing, you can see a slow blinking dot at the spotlight button at the top right corner of your Mac.

Since my girlfriend had the privilege to buy Apple product for cheaper price, I asked her a favor. She was very lucky to purchase a MacBook Pro at insanely good price. You'll dropped your jaw if I tell you :-D

I let my girl use it for a couple of days. She is so happy I can tell. She never really have the chance to really feel owning a laptop in her room. And for few days, we had wonderful time.

Yes, MacBook Pro is a sleek and beautiful machine. But when my girlfriend handed it to me, I did not turn it on right away. I had personal problem that day, and even the problem disappeared, the machines didn't really interest me. At that night, when I was so boring and my girlfriend seems a bit disappointed when she knows I didn't even take it out from the bag, I light it up. Yeah. It is Leopard. My mom have a MacBook and I've played with Leopard so looking at my MacBook Pro still nothing to me. The nice metallic machine didn't captivate me at all because I have experience my PowerBook for 5 years.

Until I started to USE it. Yes. I admit. Software captivates me a lot. Every button, every option and every menu I explore on Leopard, they sit perfectly. Apple programmer really knows how to balance the need and not need. They have added so much features and most of them I craved on when I use Tiger last time.

But that didn't fully satisfied me. With dual core, this machines wasn't really do much work. Guess, what is my attempt on my PowerBook last time? PowerBook running Leopard Server. Yes. It didn't work. My PowerBook can't read dual layer disc. There are few workaround I used, but no avail. The next day I went to my bachelor house - is this what people call? :-p - and grab the dual layer disc and install Leopard Server. Hehe. It feels like I'm rocketing to the sky! I have used all names of server - Solaris, HP-UX, Linux, FreeBSD - but this is the NEATEST UNIX SERVER EVER!

Since this post is not about Server, I will stop now. I'm sure I got a lot coming. Only software excites me. And only that excitement can lead me to blogging :-)

PS: I want to thank my girl. You are a wonderful person. Take a good care of my tiger, baby.

❖ Boot Camp : Ignore the Installation Guide

Yes, ignore it. You don't need it. What you need for boot camp setup is this post :-p which have I kindly made you a list. You need:

1. Windows Installation CD for installation of course.
2. Leopard Installation CD that will take care the drivers for you.
3. Gut. Which you don't really need because Boot Camp will cause you no pain.

During the journey you should:

1. Format the prepared partition named BOOTCAMP. Just choose (quick) because you can't wait to see Windows on your mac right? I choose FAT32 so that I can write files to it when I'm running Leopard. But if you want the more advance NTFS, no problem.
2. When Windows is installed, you may find that the eject button on your mac keyboard is not working. Simply go to My Computer and right click on the D: drive. Choose eject from there. Then insert your Leopard installation disc and you'll be surprise that the setup is just in one click.

I got a hiccup during my first and second attempt, so I advise you to use a good version of XP or Vista.

PS: I love mac. I have to use Windows because people pay me to.

333348.1 Install 10gR2 on Solaris 64 bits fails with: 'library -ldce: not found'

To implement the solution, you can use the patch for the bug or use a workaround:

A) Use the patch
Download patch 4589082 from metalink and apply it following instruction in README file
and install 10.2 software

B) Use the workaround
Rename /usr/lib/libdce.so to other name. Do installation before rename back the file in first step.

What Shadow Holds...

When passwords are shadowed, the /etc/passwd file shows '*', 'x', or another character, instead of the password and /etc/shadow holds the following user information:

* User login name
* Salt and Hashed password
* Days since Epoch of last password change
* Days until change allowed
* Days before change required
* Days warning for expiration
* Days before account inactive
* Days since Epoch when account expires
* Reserved

apt-get update problem

One of the reason which the reason i had is the incorrect date. So try check your date.

nfs setup on solaris 10

Edit /etc/dfs/dfstab file and add this line for example:

share -F nfs -o rw -d "for grid" /opt/n1ge6

Save it and run:

# svcadm restart network/nfs/server:default

or you can user shareall command.

hints : man dfstab share

debian inetd restart

After configuring /etc/inetd.conf

/etc/init.d/openbsd-inetd restart

enable start rsh / rlogin service on solaris 10

Add these to /etc/inetd.conf

# RSHD - rsh daemon (BSD protocols)
shell stream tcp nowait root /usr/sbin/in.rshd in.rshd
shell stream tcp6 nowait root /usr/sbin/in.rshd in.rshd

The inetd was not enabled, so a extra svcadm enable did the trick

% svcadm enable svc:/network/inetd:default
% svcadm enable svc:/network/login:rlogin
% svcadm enable svc:/network/shell:default
% svcadm enable svc:/network/login:rlogin
% svcadm refresh inetd

rsh

Make sure username are the same on client and remote.

server side
You need ~/.rhosts file with this line:
192.168.1.5 codept

OR you can write this line in /etc/hosts.equiv

client terminal
$ rsh remotehost date

WARNING! RSH is not secure.

ssh client bypass password authentication

client side
$ ssh-keygen -t rsa
$ scp ~/.ssh/id_rsa.pub servername:

server side
$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

client side
$ ssh-agent $SHELL
$ ssh servername

DONE!

convenient way is to add `ssh-agent $SHELL` line in shell profile file.

execution host installation : Unsupported local hostname

Unsupported local hostname
--------------------------
The current hostname is resolved as follows:

Hostname: frog.pond
Aliases: frog
Host Address(es): 127.0.1.1

It is not supported for a Grid Engine installation that the local hostname contains the hostname "localhost" and/or the IP address "127.0.x.x" of the loopback interface. The "localhost" hostname should be reserved for the loopback interface ("127.0.0.1") and the real hostname should be assigned to one of the physical or logical network interfaces of this machine.

Installation failed.

Check /etc/hosts and replace the ip with the correct one.

Save putty default settings

I hope there is an easier way to save the default settings for Putty. Rather than have to write 'Default Settings' in the Saved Sessions textfield, and click Save. By the way, I use PortaPutty. Because it stores saved sessions in a folder, not in the Windows Registry like what original Putty does. So you can store Putty on your thumbdrive.

edquota problem | open is a directory

You should touch a filename quota, not to create a folder quota. Rename it or remove the folder.

crontab edit problem

if crontab -e gives some random number, and you didn't see any existing cron, might be you didn't set your EDITOR variable:

$ export EDITOR

understanding between blocks and kilo bytes

I admit I'm a bit slow for this kind of basic convertion. During my young age, I always wonder about blocks and bytes and how to convert between them and recently it became clear after some try and error calculation on df output. This is important because some program require user to input size in blocks such as ulimit.

In ulimit manpage, I read an option which is
-c The number of 512-byte blocks on the size of core dumps.

So I can assume that 1 block equals to 512 bytes (to reader, please assist, thanks). If I look at one line of my df output:

/export/home (/dev/dsk/c0t0d0s7 ):53645828 blocks 3232280 files

Then I know that my home directory took 53645828 * 512 / 1024 of Kilobytes. To be sure it is correct, use df -b:

/dev/dsk/c0t0d0s7 26822914

That means 53645828 blocks equals to 26822914 bytes.

one of the reasons apt-get fails

My apt-get failed lastnight, and I realized it was because of my /etc/services:

finger 79/tcp
ssh 80/tcp # customized port
ssh 80/udp # customized port
#www 80/tcp http # WorldWideWeb HTTP
#www 80/udp # HyperText Transfer Protocol
link 87/tcp ttylink


After I commented the ssh lines and uncommented the www lines, apt-get runs fine.

insmod Insert an LKM into the kernel.
rmmod Remove an LKM from the kernel.
depmod Determine interdependencies between LKMs.
kerneld Kerneld daemon program
ksyms Display symbols that are exported by the kernel for use by new LKMs.
lsmod List currently loaded LKMs.
modinfo Display contents of .modinfo section in an LKM object file.
modprobe Insert or remove an LKM or set of LKMs intelligently. For example, if you must load A before loading B, Modprobe will automatically load A when you tell it to load B.

..and a script thanks to Sandra Henry-Stocker & David Cashion

cron, at by example b4 rtfm

want to use cron? first create a script

#!/bin/sh
apt-get update

and create mycron.txt(or w'ever name u want), add:

30 23 * * * /home/bambino/script

will run script on 11.30pm everyday. finally, `crontab mycron.txt` as root

want to use at? just `at 11pm 2days`, then enter your commands.

bambino:/home/bambino# at 11pm + 2days
warning: commands will be executed using /bin/sh
at> apt-get update
at> [^D]
job 4 at 2007-01-22 16:00
bambino:/home/bambino#

will run update apt 2days later at 11pm.
to list jobs, `atq`
to show spec. job, `at -c [jobnumber]`

apache, authentication, htaccess, htpasswd

Create a file .htaccess in the web directory

#.htaccess
AuthUserFile /home/bambino/public_html/.htpasswd
AuthGroupFile /dev/null
AuthName EnterPassword
AuthType Basic
require user bambino

To create a user, `htpasswd -c .htpasswd bambino`

navigating Solaris default man pages sucks

Solaris man pages are using more.

So to change to less, set PAGER environment variable to less:

$ export PAGER="less"

Update August 18th '07

# export PAGER="less"
PAGER=less: is not an identifier

so i use,
`PAGER="less"; export PAGER`

enable rstatd on Solaris 10

rstatd is important for stdperfmeter to work. But 5.10 disables it by default.

# svcadm enable rstat

to check, use rpcinfo -p

secure solaris, auto-boot and eeprom

Auto-boot parameter in eeprom can disable Sun's machine from entering PROM.

# eeprom "auto-boot?"=false

And there are more parameters for consideration credit to Jeff Hunter

today's note: solaris

kayword: solaris unable to boot CD DVD PROM man -k windex

Get into PROM during boot: command + A

if `man -k` returns /usr/share/man/windex: no such file or directory we have to create the windex database which is also used by whatis and apropos by `catman -w`. While in Linux, `catman` is enough.

classful addressing

10000000 - 10111111 = class B = 128.xxx.xxx.xxx - 191.255.xxx.xxx
11000000 - 11011111 = class C = 192.xxx.xxx.xxx - 223.255.255.xxx
11100000 - 11101111 = class D = 224.xxx.xxx.xxx - 239.x.x.x

Safe kill procedure

kill pid (sends a TERM, wait 5 seconds)
kill pid (yes, try again, wait 5 seconds)
kill -INT pid (wait for it)
kill -INT pid (damn, still not dead?)
kill -KILL pid (same thing as -9)
kill -KILL pid (something is wrong)

If the process is still running, then stop sending it signals. It's either stuck in I/O wait or it's Defunct. 'ps auxw | grep processname', if you see it's in state D, then kill its parent process (the 3rd column of 'ps -ef' is the parent pid). If it's in I/O wait, then you have a deeper system problem. Most home users will never have this problem.
