Troubleshooting in Linux

noreply@blogger.com (simplengRoeL) — Mon, 11 Oct 2010 06:17:00 +0000

I should not forget the basic of troubleshooting. Walang kwenta kung marunong kang gumamit ng mga open source operating system kung hindi mo naman alam mag troubleshoot.

sa rpm-based distro.

## rpm -qa | grep
kung may hinahanap kang package name na dapat nakainstall

## netstat -tunap
tignan ung net status mo. nakalagay ung mga nakaconnect sa mga port mo.

Generic troubleshooting tips

1) Use tail –f to watch log file in real time, advantage is simple you can spot error or warning message in real time.
tail –f /path/to/log/file
Example(s):
# tail –f /var/log/maillog

2) Use telnet command to see if you get response or not. Sometime you will also see some informative message:
telnet ip port

Example(s):
# telnet localhost 53
# telnet localhost 25

3) Make sure you can see PID of your service.
pidof service-name
cat /var/run/service.pid
Example(s):
# pidof sshd
# cat /var/run/sshd.pid

4) You need to make sure that your DNS server or third party DNS server (ISP) is accessible. This is an important step, as many network services depend upon DNS; especially sendmail/postfix or Squid etc for example. Run dig or nslookup. No timeout should occurred.

# dig your-domain.com
# nslookup gw.isp.com
# more /etc/resolv.conf

5) For networking troubleshooting, make sure your ip address configuration is right, gateway, routine, hostname etc all configured. Here is list of tools on RedHat Linux to verify or modify information:

Hostname verification or setup tools

hostname : To get hostname of server.
hostname –s : To get FQDN hostname of server
more /etc/sysconfig/network : To setup hostname and networking can enabled or disabled.
dnsdomainname : List or setup domainname.
more /etc/hosts :Make sure at least localhost entry do exist.
Ethernet configuration tools

ifconfig : To see running network card information.
ifconfig eth0 up|down : To enable|disable network interface
service network reload|restart|stop|start : To reload (after changed made in ip config file)|restart|stop|start network interface with all properties.
route|netstat –rn : To print routing table
ping ip-address : To see if host is alive or dead
more /etc/modules.conf : To see your network card configuration alias for eth0 exists or not.
lsmod : To list loaded modules (read as drivers), here you need to see that eth0 module is loaded or not, if not loaded then use insmod to insert (load) driver.
dhclient : Dynamic Host Configuration Protocol Client, run this if your Ethernet card is not getting ip from DHCP box on startup; this command does by default shows useful information.
To see if service blocked because of access control

iptables –n –L : To list all iptable rules; useful to see if firewall blocks service or not.
service iptables stop|start : To start|stop iptables
more /etc/xinetd.conf
OR

more /etc/xinetd.conf/SERVICENAME = To list configuration of xinetd server. Again useful to see if firewall xinetd based security blocks service or not (xinetd includes host-based and time-based access control)
more /etc/hosts.allow : To see list of hosts allowed to access service.
more /etc/hosts.deny : To see list of hosts NOT allowed to access service. NOTE first TCP wrappers (hosts.allow|hosts.deny) checked and then xinetd-based access control checked.
more /etc/path/to/application.conf : See your application configuration file for access control. For example smb.conf and many other applications/services got own access control list in application. You need to check that as well.
Read man pages of all above command for more details on syntax and usage.

Hey Shittymind,

It's been a while since you posted. Never heard much from you anymore. How is it going? As for me nothing much. Hey gratz for the gift, if you know what i mean. It's a blessing bro. Now you've got someone to have your motivation. Would it be like you? Or Would it be a princess? Anyways man, good luck. What are your plans for next week? the next month? I keep calling you but you never answered my calls. Hmmm, i think your preoccupied right now. Give me a ring when you need to talk alright?
How is your girl doin? Seems like you two are havin' a hard time eh? your both different man. you may have fights but it's what keeps you from knowing each other deeper. Don't give up bro. You know those challenges are just things that builds the foundation of your relationship so don't go wasting your time arguing who's wrong or who's right. you know what i mean? peace!

P.S.
What the fuck are you up to posting linux shit in your blog?

Cheers,
--WEL--

Hey Wel,

Nice to here from you! It's a relief you gave me buzz or somethin..yeah, We never got to talk and hang out lately, i'm sorry man. I feel like i'm so alone carrying an invisible 2 tons of weight, if you know what i mean. I don't know where to start. You know, my family is killing me. They are so hard on me man. I don't know their issues or something. They wouldn't let me face this kind of trouble. Although i already told them that i can handle it. They are just freakin' afraid i'm not gonna be the man they want to be. But hey!! its my LIFE.. it was done, all i can do is to face it. right? I don't know what's up with them. Would that be a hindrance to me for being successful? nah!! They are just flaring me up. Whew! It's hard to explain to them that i have my own life now and its time for me to experience the so called "life". Uhm, I know you're always there for me an will be there for me.

Who told you about that? yeah, i'm having my first child, and i am so excited. Well, i guess i am the only one excited about it. yeah, yeah. i know it's a blessing and it's true its going to be my main motivation for my life. Can't wait for that day, I always pray to God he/she is goin to be healthy. That's all i can ask for Him for now. Hmmmm.. since when you had the authority to ask me about my girl huh!? hehehe..My girl, she's staying with her sibling for the moment, as my family was "packed" in that small room of mine. Even I can't sleep well in that room. Whenever close my eyes i can hear their noise. Aww. stress for me. She's been moody lately, what do i know about harmones anyway. Well, for now. she's not missing me, if you know what i mean. I've been reading all of her facebook status and her blogs. If you read it man, there's something into it. It's like uhm she's tired of me or something like that. I don't know. I guess she's still into him you know. She wants to patch things up with him, i guess. Hmm.. It's like before huh, i ended up being ALONE. I shouldn't be sayin this to you, lol. But how would i know she was never open to me. How i wish she would. Thanks man for the buzz. till next time.

P.S.
Mind your own business asshole. It's for future references.

Peace,

Shittymind

A bunch o f How-to's

noreply@blogger.com (simplengRoeL) — Thu, 08 Apr 2010 12:00:00 +0000

View Specs of you linux pc

If you want to view the hardware spec of your pc, you can use this command
--> lshw
By default, this command is installed on ubuntu linux but not installed on Centos. You can use you tools like yum to install it
--> yum install lshw

Mounting cdrom

If you are using a pc with linux that does not have automount feature, here are the steps that you can do to mount it on linux terminal.

* After inserting the cd, create a folder. Usually we create a folder inside folder /mnt. Type --> mkdir /mnt/cdrom.
* To mount it, type --> mount /dev/cdrom /mnt/cdrom. This step will mount the content of the cdrom to the folder /mnt/cdrom
* After you finish, just type --> umount /mnt/cdrom to unmount it from the folder.

You can also use this steps for other devices such as flash drive. To check where is the folder containing the device, type --> df.

how to check your kernel version

Sometimes you want to know the particulars about the kernel of your linux. This can be done using uname command.
To check kernel version:
->uname -v
To check kernel release:
->uname -r
To check kernel name:
->uname -s

Using crontab scheduler

Crontab is a tool for scheduling tasks for the computer to run. It will automate the jobs that needs to be done but will be difficult to be done by human because of time limitation. There are only 4 options for crontab which are -u, -e, -l and -r and the usage is described below:

* crontab -l - list all the crontab on standard output
* crontab -e - edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables
* crontab -r - remove the current crontab
* crontab -u - specify the user
o example: $ crontab -u username -l - this command will list the crontab belongs to the username

Crontab is set by running the crontab -e command and add the necessary time and the command to be run on that particular time. Crontab scheduling format are as below:

* * * * * command to be run

1st * is for minutes (0-59)
2nd * is for hour (0-23)
3rd * is for day of month (1-31)
4th * is for month of year (1-12)
5th * is for day of the week (0-7) where 0=Sunday and 7=Sunday

Example:
To backup your pc using rsnapshot everyday at 7.30 a.m.;

1. $ crontab -e
2. 30 7 * * * /usr/local/bin/rsnapshot daily
3. save your crontab setting

SSH without password

Using the below steps, you can ssh to the server from client without the entering any password.
The machine which run the ssh command is the client
The machine that the client access using ssh is the server

1. Run the following command on the client
* -> ssh-keygen -t dsa
2. File id_dsa and id_dsa.pub will be created inside $HOME/.ssh
3. Copy id_dsa.pub to the server's .ssh directory
* -> scp $HOME/.ssh/id_dsa.pub user@server:/home/user/.ssh
4. Change to /root/.ssh and create file authorized_keys containing id_dsa content
* -> cd /home/user/.ssh
* -> cat id_dsa >> authorized_keys
5. Change "StrictModes yes" in /etc/ssh/sshd_config to "StrictModes no"
6. Restart ssh server
7. You can try ssh to the server from the client and no password will be needed
* -> ssh user@server

Another alternative to the above steps is to use ssh-copy-id command. The steps are:

1. Run the following command on the client
* -> ssh-keygen -t dsa
2. File id_dsa and id_dsa.pub will be created inside $HOME/.ssh
3. Copy the id_dsa.pub to the server's .ssh directory
* -> ssh-copy-id -i ~/.ssh/id_dsa.pub user@server
4. Change "StrictModes yes" in /etc/ssh/sshd_config to "StrictModes no"
5. Restart ssh server
6. You can try ssh to the server from the client and no password will be needed
* -> ssh user@server

Resetting mysql root password

Sometimes you have to access a mysql database and you somehow does not know the password or the user of the database. The last resort is you have to use the root password but the password is unknown. There is always the way to solve anything and the way to reset the root password is described below. Enjoy!

1. Open a terminal and stop mysqld daemon if it has been started: $ /etc/init.d/mysqld stop
2. Type this command: $ mysqld_safe --skip-grant-tables
3. Open a new terminal, and access mysql database using root:
$ mysql -u root mysql
4. Change root password to new password: mysql> update user set password=password('newpassword') where user='root';
5. flush mysql privileges: mysql> flush privileges;
6. Exit mysql: mysql> exit
7. Close the terminal with the mysqld_safe command
8. Restart mysql: $ /etc/init.d/mysqld start

Backup using tar and ssh

Doing backup is important. You do not want to store your backup at the same machine where the data is stored. It is to avoid data loss when the machine broke down. To do this job, you can use tar paired with ssh to archive your important data and transfer it through network to another machine. Below are the steps:

1. Make sure the backup machine is installed with ssh server and the service is running
# yum install openssh-server
# service sshd start

2. Go to the folder where you want to backup. Use tar to archive and send it though network to backup machine
# tar -cvjf - /path/to/backup | ssh user@backupmachine "cat > /home/backup.tar.bz2"

3. Finish. Congatulations, your backup file is now safely kept in the backup machine

Setting up samba with password protection

To easily share your files to linux and windows clients, samba is still the preferred choice. In this guide I will show how to setup a samba server on centos 5 machine, that can be accessed only by certain people protected by password.

1. Install samba on the server
* # yum install samba
2. Create the group that all the samba users will be contained in, for example 'samba'
* # groupadd samba
3. Create samba users and add it to the above group, which is in this example is 'samba'. Below is the example to create a user named 'user1' and add it to group 'samba'. Set the password for user1
* # useradd user1 -g samba
* # passwd user1
4. Create the directory to be shared. In this example, i will use /home/shared. Change the ownership to root and group ownership to the 'samba' group. Change permission so that only user and group can read write and execute
* # mkdir /home/shared
* # chown -R root.samba /home/shared
* # chmod -R 775 /home/shared
5. Below is a simple setting of samba
* [global] workgroup = samba
server string = Samba Server
security = user [shared_folder]
comment = Sharing place
path = /home/shared
public = no
writable = yes
printable = no
write list = @samba
create mask = 0755
force create mode = 0755
directory mask = 0775
force directory mode = 0775
* What the above setting does basically is to setup /home/shared as samba shared directory but can only be accessed by user from group samba
6. Add user/users to samba
* # smbpasswd -a user1
7. Start smb service, restart if it has already been started
* # /etc/init.d/smb start
8. 'user1' can now access the samba server using address 'smb://samba_server_ip_address/shared_folder' at any nautilus address bar. For windows client, you can see at your 'My Network Places' and find a workgroup named 'samba'

Ubuntu forgotten password

What to do when you forgot your password for your ubuntu machine?? Here are some simple steps on how to change the password using single user mode.

1. Reboot the machine
2. When grub is loading, press 'Esc'
3. Choose 'Ubuntu kernel...........(recovery mode)'
* Press 'e' to edit the kernel parameter
* Append 'single init=/bin/bash' to the kernel parameter
4. Press 'b' to boot from that particular kernel
5. You will enter single user mode
6. Your hard drive will be in read-only mode. Remount it in read-write mode
* # mount -o remount,rw /dev/sda1
7. Change your passwd
* # passwd user
8. Reboot your machine
9. Access your machine using your new password

Congratulations, you just changed you user password using single user mode

CentOS/Fedora forgotten password

What to do if you forgot the password for your CentOS/Fedora/Redhat machine?? Here are some simple steps to change back the password by entering into single user mode of your machine provided you do not forgotten your grub password if you have set it ;)

1. Reboot your machine
2. Press 'Esc' key once grub starts loading
3. Select your kernel press 'e' on one of the kernel to edit the kernel parameter
4. Press 'e' on the line that starts with 'kernel /vmlinuz...'
5. Append ''single" or "1" at the end of the line
6. Press 'Enter'
7. Press 'b' to boot from the appended kernel
8. You are now in the single user mode of your linux machine once you get to the shell. You can now change the password of your account using command passwd
9. Reboot back your machine normally
10. You can now log in to your machine using your new password

Suse forgotten root password

In suse, if you forgot your root password, you can go to the single mode as usual. Steps are explained below:

1. Reboot the machine
2. When Startup Options(blue background in SLES) appear, choose Failsafe mode
3. In the Boot Options, append init=/bin/sh at the end of the line
4. Press Enter to boot
5. You will be presented with a shell. Change your password using command passwd root
6. Reboot the machine. root is now can be accessed using your new password

Restore GRUB

GRUB is a boot loader commonly used with linux operating system. It can be used to managed dual boot environment where linux and windows can coexist easily in a same machine without problem provided you install the windows OS first so that when you install linux, GRUB will overwrite Windows boot loader and automatically detect and manage both operating system the next time you boot your computer. Problems will happen if you alter your partitions outside the knowledge of GRUB, for example, you create new partition in your hard drive using windows. This will cause GRUB to automatically go into GRUB shell when boot. To restore back your GRUB is very simple, just follow easy steps below:

1. find in which partition does GRUB store its configuration file, which is your /boot partition. (hd0,2) means third partition of the first hard drive
grub> find /boot/grub/stage1
(hd0,2)

2. set the root for GRUB to be (hd0,2)
grub> root (hd0,2)

3. write GRUB to the Master boot record(MBR) of your hard drive. Change (hd0) to (hd0,2) to write GRUB to your /boot partition instead
grub> setup (hd0)

4. Reboot machine
grub> reboot

All those steps can also be used using livecd, if let say the grub shell did not come out but you cannot boot your machine or you cannot boot your linux due to messed up GRUB. just boot from livecd, open a terminal, and type "grub" as a superuser to go to GRUB shell

Logging your terminal activity

When typing on the terminal, sometimes we need to record what commands we have typed for later reference. Sure, we can simply copy the .bash_history file, but that file only shows what you have typed and not the result of the commands that you have typed. To do these kind of jobs, there are two applications that you can use:

1. script

To use script, simply run script before you start using your terminal

# script -f logfile.log

where -f is to flush output after each write, and logfile.log is the file to write whatever script has recorded.

After finish using script, simply type exit or logout to quit script

2. rootsh

Please install rootsh first if it is not installed. To use rootsh, run rootsh before start using your terminal similar to script

# rootsh -f logfile.log --no-syslog

where -f is to show which file will be used to record the session, in this case logfile.log and --no-syslog is to tell rootsh not to log to /var/log/messages. To quit from rootsh, type exit or logout. All the commands and output will be written to logfile.log.closed to show that rootsh has closed the session.

To view the output file of rootsh and script, more command can be used.

Send message to a user

noreply@blogger.com (simplengRoeL) — Thu, 08 Apr 2010 11:57:00 +0000

To send message to a particular user, you have to know what is the user tty. You can do this by typing:

# w

This command is used to show who is logged on and what they are doing. The output of the above command is usually like below(Click to see the image clearly):

To send message to a specific user:

$ write username tty

Example, to send message to user user1:

$ write user1 pts/3

Write you messages, and then press Ctrl-d to exit 'write'

To send message to all connected user, use wall command:

$ wall

Type your message and Ctrl-d to exit 'wall'

Send email in linux terminal

noreply@blogger.com (simplengRoeL) — Thu, 08 Apr 2010 11:56:00 +0000

To be able to do as the above mentioned, a tool named mutt is needed. Mutt is a mail user agent (MUA) and a very excellent one in my opinion. To install mutt:

* # yum install mutt

To send email, you can use this commands (Choose whichever you like):

* # echo "your messages" | mail -s "your subject" johndoe@yahoo.com
o where -s is for subject and johndoe@yahoo.com is your recipient name
* # echo "your messages" | mutt -s "your subject" johndoe@yahoo.com
o where -s is for subject and johndoe@yahoo.com is your recipient name

To send email with attachment

* # echo "your messages" | mutt -s "your subject" -a /path/to/attachment johndoe@yahoo.com
o where -s is for subject, johndoe@yahoo.com is the recipient name and /path/to/atachment is the path to attachment file

Do you wanna share something in the local area network quickly..without wasting your time with apache or any daemons..here is the technique for that..

First of all, open a terminal and move into the folder you wanna share.Say i want to share /home/xxx/Downloads folder..So open a terminal and then cd /home/xxx/Downloads.

Then type this command

python -c "import SimpleHTTPServer; SimpleHTTPServer.test();"

Then your folder can be accessed through web browser by typing http://your_ip:8000/.

Installing Apache

Everything that I suggest here will be done through terminal. To launch terminal follow these steps:
Application -> Accessories -> Terminal

1. Once terminal is open type or copy the following command:
sudo aptitude install apache2
2. Answer any questions that arise as you see fit. Once the process is finished installing you will need to test that the installation worked. To do this open another tab in your browser and in the address bar type localhost (link to help http://localhost). You should see the text “It works” and that means you have installed Apache2 correctly

NOTE:
If at the end of your installation you get an error or a message inside the terminal window that says “Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName” you can fix this by running the following command in terminal.
gksu gedit /etc/apache2/conf.d/fqdn

You might need to enter your password before the file will open. This command will open a file in gedit (a text editor for Linux).

* When gedit opens, type “ServerName localhost” (without the quotes) inside the file and click Save.
* Close the file.

Installing Mysql

Everything in the MySQL section will be done through the terminal window. To launch terminal follow these steps: Application -> Accessories -> Terminal

1. Once terminal is open type of copy the following command:
sudo aptitude install mysql-server libapache2-mod-auth-mysql php5-mysql
2. Near the end of the installation you will be asked to give a user name and password for MySQL
If you leave the user name blank it will default to “root”

That is it. At this point you should now have MySQL installed an running on your localhost. You can test this by typing mysql in the terminal window. If all is setup correctly you should get a “Welcome to MySQL monitor. Commands end with ; or \g.” and a prompt that says mysql>. From here you can run your mysql commands.

Installing PHP

Everything in the PHP section will be done through the terminal window. To launch a terminal follow these steps: Application -> Accessories -> Terminal

1. Once your terminal is open type or copy the following command:
sudo aptitude install php5 php5-common libapache2-mod-php5 php5-gd php5-dev curl libcurl3 libcurl3-dev php5-curl
2. After everything is installed you will need to restart Apache for the server to see and implement PHP
sudo /etc/init.d/apache2 restart
3. You can now test to see if PHP5 is working with Apache. To test if PHP is installed you can create a .php file inside your /var/www/ directory
sudo gedit /var/www/test.php
4. The command will open gedit (Linux text editor). Once gedit is open type in the following code:
phpinfo();
?>
5. Open a new tab in your browser and in the address bar type localhost/test.php (link to help http://localhost/test.php)

After running step 5 you should see your PHP Info page. This page will display the settings of your PHP configuration file and what is available via Apache2, MySQL and many other settings you may not care to know about. But the thing is if you see the PHP Information page you have successfully set up PHP5 to work with Apache.

Congratulations, I hope this means you have been able to install one, two or even all three of the items outlined in this post. If everything has worked out correctly you know have a local environment to develop on. Good luck and have fun.

Streaming Live and VoD

noreply@blogger.com (simplengRoeL) — Tue, 30 Mar 2010 07:12:00 +0000

First you need to setup your server.A good streaming server is the Darwin Streaming Server(DSS). It's an open source application and you can download it on apple.com. In video streaming there are a lot of things you need to consider. One would be the bandwidth of your network connection cause it eats up a lot of you bandwidth in your network.

Naaahh... tinatamad ako magturo ng tutorial..igoogle nio na lang..pero masarap pagaralan ang video streaming..hehehe..

i hate the way i feel today.

Everything's is fine. it started out fine. Why the hell i'm feeling this way today? Maybe i'm just bored. Yeah i think I'm BORED!!!

I'm bored with my work. You ask why? i'm not learning anymore. just staring at this damn graphs the whole shift, staring to this oversize lcd monitors, withstanding its heat which makes my balls cry out for cold shower.. nothing to do much. is there more challenging than this? for crying out loud? do this company have something to give to their employees? like a hands-on training. yeah training will be good. they already provided training but i call it a LECTURE. it wasn't training at all, i can google it myself! What am i saying?!? shit all i can do is to whine at my blog and never let them hear me. I guess that's better for now. whew.

And one thing..

have your ever felt that everything between you and your partner is all doing fine?
you feel good about your relationship. you feel good for both of you..you feel good that you are the only one for her life? that you're the one she's been thinking about while you're apart. blah blah blah.. but then..you suddenly bump to something like she's always reminded of .. something like a song that links them between your partner and her past..have you?

the other thing..

it's march..my sister's bday is coming up..got to find a way to patch things up with her..

but for now..

there's myself and my shittymind.

Is the way to a man's heart is through his stomach?

Well, my bhe cooked a ramen for me.. and it was a blast for my taste..i was so full. Some good lovin would be a best follow up after a good meal. Im happy she can cook! and she cooks good..a one of a kind, keeps me from falling in love with her again and again. Hhhaayy...love the ramen!

Oye! a way to a man's heart is my bhebhe's ramen! hahaha

When she cries

noreply@blogger.com (simplengRoeL) — Wed, 17 Feb 2010 19:50:00 +0000

The road I have travelled on
Is paved with good intentions
It's littered with broken dreams
That never quite came true
When all of my hopes were dying
Her love kept me trying
And she does her best to hide the pain that she's been through

When she cries, at night
And she doesn't think that I can hear her
She tries, to hide all the fear she feels inside
So I pray, this time
I can be the man that she deserves
'Cause I die a little each time
When she cries

She's always been there for me
Whenever I've fallen
When nobody else believed
She'd be there by my side
I don't know how she takes it
Just once I'd like to make it
Then there'll be tears of joy
That fill her loving eyes

When she cries, at night
And she doesn't think that I can hear her
She tries, to hide all the fear she feels inside
So I pray this time
I can be the man that she deserves
'Cause I die a little each time
When she cries

So I pray this time
I can be the man that she deserves
'Cause I die a little each time
When she cries

somehow i know when she's hurt, when she's in pain, when she's not in the mood somehow i know..no matter how she hides it with her smile..right at the moment i saw her, i knew she's sad and lonely..i can tell whether she's happy or not..most of the time she's taking it by herself..i hope i can mend how she feels whatever she may feel..

Sleep Deprivation

noreply@blogger.com (simplengRoeL) — Sat, 13 Feb 2010 01:22:00 +0000

waaaah! alarming..

Generally, lack of sleep may result in

* aching muscles
* dizziness and nausea
* dry mouth[citation needed]
* hallucinations
* hand tremors
* headaches
* increased blood pressure
* increased risk for diabetes
* increased risk of fibromyalgia
* irritabilityhttp://www.blogger.com/post-create.g?blogID=2310858111184642124
* memory lapses or loss
* nystagmus (rapid involuntary rhythmic eye movement)
* obesity
* slowed word recall[citation needed]
* temper tantrums in children
* yawning
* symptoms similar to:
o Attention-deficit hyperactivity disorder(ADHD)
o psychosis

Sleep deprivation can adversely affect brain and cognitive function.[16] A 2000 study, by the UCSD School of Medicine and the Veterans Affairs Healthcare System in San Diego, used functional magnetic resonance imaging technology to monitor activity in the brains of sleep-deprived subjects performing simple verbal learning tasks.[17] The study showed that regions of the brain's prefrontal cortex displayed more activity in sleepier subjects. Depending on the task at hand, the brain would sometimes attempt to compensate for the adverse effects caused by lack of sleep.

The temporal lobe, which is a brain region involved in language processing, was activated during verbal learning in rested subjects but not in sleep deprived subjects. The parietal lobe, not activated in rested subjects during the verbal exercise, was more active when the subjects were deprived of sleep. Although memory performance was less efficient with sleep deprivation, greater activity in the parietal region was associated with better memory.

A 2001 study at Chicago Medical Institute suggested that sleep deprivation may be linked to more serious diseases, such as heart disease and mental illnesses including psychosis and bipolar disorder.[18] The link between sleep deprivation and psychosis (psychiatric disorders) was further documented in 2007 through a study at Harvard Medical School and the University of California at Berkeley. The study revealed, using MRI scans, that lack of sleep causes the brain to become incapable of putting an emotional event into the proper perspective and incapable of making a controlled, suitable response to the event.

A 2002 University of California animal study indicated that rapid eye movement (REM) sleep was necessary for turning off neurotransmitters and allowing their receptors to "rest" and regain sensitivity which allows monoamines (norepinephrine, serotonin and histamine) to be effective at naturally produced levels. This leads to improved regulation of mood and increased learning ability. The study also found that REM sleep deprivation may alleviate clinical depression because it mimics selective serotonin reuptake inhibitors (SSRI).

This is because the natural decrease in monoamines during REM is not allowed to occur, which causes the concentration of neurotransmitters in the brain, that are depleted in clinically depressed persons, to increase. Sleep outside of the REM phase may allow enzymes to repair brain cell damage caused by free radicals. High metabolic activity while awake damages the enzymes themselves preventing efficient repair. This study observed the first evidence of brain damage in rats as a direct result of sleep deprivation.[19]

Animal studies suggest that sleep deprivation increases stress hormones, which may reduce new cell production in adult brains

Attention

Among the numerous physical consequences of sleep deprivation, attention deficits are perhaps the most important; attentional lapses in mundane routines can lead to unfortunate results, from forgetting ingredients while cooking to missing a sentence while taking notes. The attentional lapses also extend into more critical domains in which the consequences can be literally life-or-death; traffic accidents and industrial disasters can result from inattentiveness attributable to sleep deprivation.

To empirically measure the magnitude of these attention deficits, researchers typically employ the psychomotor vigilance task (PVT) which requires the subject to press a button in response to a light at pseudo-random intervals. Failure to press the button in response to the stimulus (light) is recorded as an error, attributable to the microsleeps that occur as a product of sleep deprivation.

Crucially, individuals' subjective evaluations of their fatigue often do not predict actual performance on the PVT. While totally sleep-deprived individuals are usually aware of the degree of their impairment, lapses from chronic (lesser) sleep deprivation can build up over time so that they are equal in number and severity to the lapses occurring from total (acute) sleep deprivation. Chronically sleep-deprived people, however, continue to rate themselves considerably less impaired than totally sleep-deprived participants.[24] Since people usually evaluate their capability on tasks like driving subjectively, their evaluations may lead them to the false conclusion that they are able to perform tasks that require constant attention when their abilities are in fact impaired.

Impairment of ability

The dangers of sleep deprivation are nowhere more apparent than on the road; the American Academy of Sleep Medicine reports that one in every five serious motor vehicle injuries is related to driver fatigue, with 80,000 drivers falling asleep behind the wheel every day and 250,000 accidents every year related to sleep[25], though the National Highway Traffic Safety Administration suggests the figure for traffic accidents may be closer to 100,000.[26] The AASM recommends pulling off the road and taking a 15- or 20-minute nap if you begin to feel drowsy.[25]

According to a 2000 study published in the British Medical Journal, researchers in Australia and New Zealand reported that sleep deprivation can have some of the same hazardous effects as being drunk.[27] People who drove after being awake for 17–19 hours performed worse than those with a blood alcohol level of .05 percent, which is the legal limit for drunk driving in most western European countries and Australia. Another study suggested that performance begins to degrade after 16 hours awake, and 21 hours awake was equivalent to a blood alcohol content of .08 percent, which is the blood alcohol limit for drunk driving in Canada, the U.S., and the U.K.[28]

In addition, as a result of continuous muscular activity without proper rest time, effects such as cramping are much more frequent in sleep-deprived individuals. Extreme cases of sleep deprivation have been reported to be associated with hernias, muscle fascia tears, and other such problems commonly associated with physical overexertion. Beyond impaired motor skills, people who get too little sleep may have higher levels of stress, anxiety and depression, and may take unnecessary risks.[citation needed]

A new study has shown that while total sleep deprivation for one night caused many errors, the errors were not significant until after the second night of total sleep deprivation.[29] However, combining alcohol with acute sleep deprivation results in a trebled rate of driving off the road when using a simulator.[30]

The National Sleep Foundation identifies several warning signs that a driver is dangerously fatigued, including rolling down the window, turning up the radio, trouble keeping your eyes open, head-nodding, drifting out of your lane, and daydreaming. If you notice one of these cautionary signals, you should pull off the road and take a nap, even if you do not feel especially tired. At particular risk are lone drivers between midnight and 6AM, when the circadian rhythm is at its lowest point.[31]

Sleep deprivation can negatively impact performance in professional fields as well, potentially jeopardizing lives. Due largely to the February crash of a regional jet in Buffalo, N.Y., which killed 50 people and was partially attributed to pilot fatigue, the FAA is reviewing its procedures to ensure pilots are sufficiently rested.[32] A 2004 study also found medical residents with less than four hours of sleep a night made more than twice as many errors as residents who slept for more than seven hours a night, an especially alarming trend given that less than 11% of surveyed residents were sleeping more than seven hours a night

Microsleeps

Microsleeps occur when a person has a significant sleep deprivation. The brain automatically shuts down, falling into a sleep state for a period that can last 10 to 60 seconds. The person mentally falls asleep no matter what activity he or she is engaged in. Microsleeps are similar to blackouts and a person experiencing them is not consciously aware that they are occurring. Great sleep deprivation mimics psychosis: distorted perceptions can lead to inappropriate emotional and behavioral responses.[34]

Wouldn't it be nice

noreply@blogger.com (simplengRoeL) — Sat, 06 Feb 2010 16:57:00 +0000

Wouldn't it be nice if we were older
Then we wouldn't have to wait so long
And wouldn't it be nice to live together
In the kind of world where we belong

You know its gonna make it that much better
When we can say goodnight and stay together

Wouldn't it be nice if we could wake up
In the morning when the day is new
And after having spent the day together
Hold each other close the whole night through

The happy times together we've been spending
I wish that every kiss was never ending
Oh Wouldn't it be nice

Maybe if we think and wish and hope and pray it might come true (run, run, run)
Baby then there wouldn't be a single thing we couldn't do
We could be married (we could be married)
And then we'd be happy (then we'd be happy)

Wouldn't it be nice (ba ba ba ba ba ba ba ba)

You know it seems the more we talk about it
It only makes it worse to live without it
But lets talk about it
Oh, wouldn't it be nice

good night my baby
sleep tight my baby

good night my baby
sleep tight my baby

good night my baby
sleep tight my baby

good night my baby
sleep tight my baby
