2. Gunakan deterjen khusus. Gunakan detergen, turuti aturan pakainya dan khusus untuk mobil.

3. Dahulukan velg-nya. Ketika mencuci mobil bagian yang sebaiknya paling awal dicuci adalah velg. Bersihkan pula bagian yang sulit, semisal sela-sela velg dan bagian kolongnya.

4. Mandikan badan mobil. Semprotlah seluruh badan mobil secara merata. Tekanan semprotan tidak boleh terlalu kuat, semprot dengan air yang menyiram biasa saja.

5. Keringkan mobil dengan lap katun. Gunakanlah lap katun yang lembut saat mengeringkan mobil. Letakkan lap pada permukaan mobil yang akan dikeringkan, biarkan hingga air terserap oleh lap. Jangan mengusap mobil saat mengeringkannya, sebab hal itu akan menggores permukaan mobil.

6. Gunakan penyedot debu alias vacuum cleaner. Biarkan beberapa saat agar sisa-sisa air cepat mengering. Dan untuk membersihkan kotoran di dalam kabin gunakan penyedot debu alias vacuum cleaner.

CPanel Guide: allow SSH connection to a Cpanel server

kriwelz — Wed, 02 Jun 2010 12:38:00 +0000

As an administrator of a cpanel server sometimes WHM is cannot handle all the actions you want to do, thats when SSH comes in handy to handle problems by directly accessing the command line.

To allow SSH connection to a CPanel server you need to do several things in your WHM :
1. Go to the “ConfigServer Security&Firewall Link”
2. Click on the “Firewall configuration” button, then let it show the configuration, find the “TCP_IN = ” text box and fill the port you want to allow to SSH access your server, let say u fill 9000, Klik “Change button”
3. When you go back to the ConfigServer homepage, click the “Firewall Allow IPs”, insert your IP or using this line below
tcp:in:d=YYYYY:s=xxx.xxx.xxx.xxx
whereas Y is your port number that you have set on the 2nd step, and X is the IP you want to allow SSH connection to your CPanel server,
Next Klik the “Change” button, then klik the “Restart LFD+CSF” button

Thats it, your done, but hey.. when your allready allowed SSH connection to your CPanel server, you access the root ??? relax, all you need to do is :
1. go back to your WHM,
2. search for “Manage Wheel Group Users” then click the link,
3. go to the “Add a user to the wheel group” then click the link you want to add, click the “Add to group” button.

wait a minute… before continuing, you still have one last step to do, that is adding your IP to Host Access List,

Voila, now you can use the “su -” command to login as root in your command line.

Hope this post helps you manage your server,

Schedule shutdown

kriwelz — Fri, 30 Apr 2010 10:15:49 +0000

Commands
at- Execute a task at a specific time. For example, shutdown computer, send birthday remainder etc. Useful to schedule one job at a time or a single future event.
cron – If you want to shutdown Linux box automatically everyday 8 pm then you need to use cron instead of at command (see below for examples). Useful to schedule recurring events or daily events such as backup data, or check system security etc.

at Command Examples

Let us see how to shutdow a Linux automatically at 8 pm, type the command at 8pm and press [enter] key, then type halt followed by enter key. To save your job press CTRL+D.

# at 8pm

Sample outputs:
at> halt

(Press CTRL+D)

Try out the following utilities:
atq – List the current at jobs pending.
atrm – Used to remove pending at jobs.

at command accept fairly complex time specifications, for example:
Run job at 6am on monday:
at 6am monday

Run job in 5 minutes time:
at now + 5 minutes

Run job at 4pm but 3 days later:
at 4pm + 3 days

Run job at 10am on 31st July:
at 10am Jul 31

See the file /usr/share/doc/at/timespec for complete time specifications and read man pages of at, atq, atrm. Make sure you have atd service running, if not start it using the following command:
# /etc/init.d/atd start

I personally wouldn’t schedule a shutdown if i was downloading a few tarballs and the system needed to be off when it was complete, unattended.
what if the speed decreases and it doesn’t finish in time?
Sure, you could expect it to take long and give it lots of time… But what if it gets done early, wouldn’t it be better if it shut down after it was complete, and not wait for the set time?
best to do something like this, chain commands. so you tell it to download the file and then when its done, shutdown.
wget http://somehwere.com/path/to/some.file && halt

note: it has to be double & signs. single one will cause both commands to execute at the same time. double causes it to wait for the first one to exit (clean exit or not) before continuing.
i personally would probably use more along the lines of
wget http://somehwere.com/path/to/some.file 2>/home/kai/wget.log && halt

so level 2 outputs (errors) are logged. if the file stopped downloading before it was done, i would then know why by reading the output of wget.log

scheduled shutdowns with at or cron are better for just having a system shutdown _nomatter what_ at said time. if you want your tasks to finish first, chain them.

Or if you want to schedule a shutdown in the next 24 hours:

shutdown -h time

e.g:
shutdown -h 06:45

Linux find large file size

kriwelz — Thu, 14 Jan 2010 10:42:45 +0000

Sometimes after using your linux box, data consumes spaces in your hard drive, then you start to think how to find large file size in linux box, after searching a while then i found the solution for this,the following command will list all files in sorted order in human readable format

find /var -size +10000k -print0 | xargs -0 ls -lSh

the explanation for this is : look for files bigger than 10MB in the /var directory, sort it by biggest file first (descending), and show it in human readable format (MegaBytes)

That’s it.. now you can find large file size in your linux box, simple right
