ssh can be used in while or for loop

-n Redirects stdin from /dev/null (actually, prevents reading from stdin). This must be used when ssh is run in the background. A common trick is to use this to run X11 programs on a remote machine. For example, ssh -n shadows.cs.hut.fi emacs & will start an emacs on shadows.cs.hut.fi, and the X11 connection will be automatically forwarded over an encrypted channel. The ssh program will be put in the background. (This does not work if ssh needs to ask for a password or passphrase; see also the -f option.)

ssh do not display motd

Use quite option:

ssh -q host

Semaphores exhausted: OS support please check: 0 semaphores available.

//Solaris 10:

# expr `ipcs -s | wc -l` - 3
you will get the current number of semaphores ids

# prctl -n project.max-sem-ids $$
the maximum limit is the privileged value

Temporarily increase the value to double
# prctl -n project.max-sem-ids -v 256 -r -i project default


//Solaris 9:
The default semmni value (max sem ids) is 10. Set the new value in the /etc/system and reboot is compulsory.

# expr `ipcs -s|wc -l` - 3
you will get the current number of semaphores ids

Check your $DISPLAY.

echo $DISPLAY

Should be like localhost:10.0

10 could be 11 12 13 etc

If you dont see that, check where $DISPLAY value comes from

grep DISPLAY ~/.*

try commented it out

if still not work try google somewhere else, u may find

1. plumb the ip6 localhost
2. use sshd -4 (edit /lib/svc/method/sshd for solaris 10)
3. Change ListenAddress in sshd_config from :: to 0.0.0.0

Some alteration to Mike's Sidebar Login code

Mike is a brilliant guy. He developed a WordPress plugin which place a login widget on to the sidebar. I loved it the first time I used it.

Not to disrespect, but I want it to look more compact and clean. So I made some modification to the input text area. It would be nice if the labels are inside the text area and disappear when they are clicked upon.

Customize Time Machine Intervals

Why? You don't want Time Machine to backup your data too frequently that it fills up your backup disk quickly. Unless you are someone who works in a production area or your files moved and altered very frequently in one day.

What happen when your backup disk is full? This is what happened to my mom. It automatically removes the oldest files until the latest backup made it's way safely to the backup disk. You don't want that. The worst thing is, it doesn't ask for your permission. Or make it this way. It doesn't ask a question that can be understand by a non geek user.

When you restore a large files to the current time, Time Machines will do hourly backup in the next hour. This will fill up your backup disk fast. What happen if the large file that you just restore isn't the file that you want? Some people will go back in time and restore another one. And they forget to remove the earlier files.

Time Machine users should know how this thing works before they start using it. Unless they have a super huge disk or unlimited storage, they should aware of their backup disk usage. So if needed, you can customize your backup interval using TimeMachineEditor.

Ubuntu 10.04 Lucid Lynx on HP Mini 5101 Setup

This week I 'ubuntunized' - there goes a new word! - my sister's netbook. She frowned about the viruses. I spilled the offer. Time has come baby!

Since 5101 doesn't come with a disc drive, I've created a Ubuntu bootable USB using Startup Disk Creator which comes pre-installed with 10.04 under System > Administration menu.

Installation and setup wasn't quite a breeze. Now everything is working - broadband modem, webcam, printer, functional buttons and power management. Wireless driver doesn't work right away but Lucid will prompt you to activate the 'proprietary drivers'. If not, just manually find it under Administration > Hardware Drivers menu.

Well I am going to tell you my actual story. There was a few things that didn't work properly or didn't work at all - webcam, Gwibber, broadband - but to my surprise, everything solved after I figure out the keyring issue. But this is just a blind theory.

What is it? Well if you authorized Lucid to remember passwords, keyring is where he stores them.

All started when Gwibber - an app that update social network status simultaneously - did not respond on different Ubuntu account. So I ran it from the terminal and saw an error mentioning keyring daemon.

I also notice something in the Passwords and Encryption Keys under the Application > Accessories menu - "can't communicate with keyring daemon".

So I googled. I discovered that some people edit the Certificate and Key Storage in the Startup Application Preferences. Remove all arguments. Leave it as "gnome-keyring-daemon".

I'm not sure how but it also solved my broadband problem. My webcam suddenly happen to work too. Also worth to mention on the broadband issue if you're experiencing it, once I disconnect the modem, I can never simply reconnect it. I have to reboot with the modem plugged in.

My wild guess is, something to do with keyring & permissions. So if you happen to read this in an attempt to 'ubuntunize' your netbook, go for it! Lucid is awesome!

...but wait. You might want to consider UNE instead of full fledge Ubuntu. Adios :)

Free, Simple, Looks Pro & Legit. My friend receive $, so I just give it a try.

Adding Space to an ESX Server Virtual Disk

ESX 3.5. Use clone to backup. Go into the vm directory which suppose to be in the corrected data store directory. Grep scsi on *vmx file to identify which disk u want to extend. First one should be C: and second should be D: etc etc.

# vmkfstools -X 60G virtualdiskiwanttoextend.vmdk

Refer here. Careful with the number you choose. Above example means change the disk capacity to 60GB, not by 60GB.

2. Disc image, a size of DL DVD
3. Documents
4. VMs

It's been long since we had a picture posted here.. Wait, had we?

Now currently converting 2 laptops to Ubuntu. Lately I've been
promoting solution to run Windows on VirtualBox. The catch is of
course, less virus threat & VB snapshot. Compiz effect also gives
bonus to attraction.

P/s: mood is unhappy because my huge hfs filesystem is corrupt due to
improper usb removal

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.

#!/bin/sh

# backup-sms.sh

DATE=`date +%y%m%d`

echo "${DATE}"

if test -f /var/mobile/Library/SMS/sms.db.$DATE

then echo "Today's backup already exists."; exit; fi

if ! test -f /var/mobile/Library/SMS/sms.db.$DATE

then cp -npv /var/mobile/Library/SMS/sms.db /var/mobile/Library/SMS/sms.db.$DATE; fi

ls -lrt /var/mobile/Library/SMS/

if test -f /var/mobile/Library/SMS/sms.db.$DATE

then echo "Today's backup successful"; fi

Update: Something fishy here. Applications installed by Cydia do not appear on the springboard...

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?

$ ls -al | sort -n +4
sort: open failed: +4: No such file or directory

Convert plist binary to xml, back and forth.

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.

Phone Number Fix on iPhone (localization)

Problem is iPhone doesn't recognize callers. Although they exist in the address book, iPhone only show their number with extra country code prefix.

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

EDITOR=`which vi`; export EDITOR

Few servers gave me hard times on stty important function. So I:

echo "stty erase ^H
stty kill ^U
stty intr ^C
TERM=vt100
EDITOR=`which vi`
export TERM EDITOR" >> ~/.profile

Use putty to access vnc using ssh tunnel

This is to overcome firewall which filter connection on the application layer. In putty:

Hostname: ssh_server
X display location: localhost:0
Source port: 5901
Destination: vnc_server:5900

On vnc, connect to localhost:1

16:06 < codept> is there any tool to ...like ...present logs in the /var/log
...in more simpler format, let say httpd-access.log, a tool
that can analyze it and gives number of connection for each
unique source, ...that is just an idea
16:10 < geek00l> codept, we call it - awk, sed, sort, uniq, grep and fuck

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.
