Shutdown computer server with the power button

Shutdown computer server with the power button
If we ever use windows, then to menshutdown windows, enough
by pressing the power button once, then the system will shutdown normally.
In ClearOS, default if doing so is to restart the system, to change
to shutdown the system then do the following:
1. Edit the following file / etc / inittab
2. Find and change the code to be like below
...................
# Trap CTRL-ALT-DELETE
ca:: ctrlaltdel: / sbin / shutdown-h now


3. Save changes
Next, if you press the power button on the PC only once, then the system will
start routine to shutdown

Looking at the proxy server activity

Looking at the proxy server activity
To determine the course of a proxy, you can monitor squid access.log files
Press Alt + F2 to enter the CLI mode. Enter the root user and password, run
this command:

code :
# tail -f /var/log/squid/access.log



If the proxy path, you will find the display ongoing cache access during
there are clients who access the Internet.

To exit press Ctrl + C
Back to the server admin menu, press Alt + F1

Clearing the cache proxy manually

Clearing the cache proxy manually
Actually, the proxy cache is not necessary in the empty, because it will automatically
remove itself if the cache that has long reached a certain parameter, but
sometimes we want to clear the cache manually
1. Turn off the running squid

code :
#service squid stop 


2. Clear the cache of his

code :
#rm –rf /direktori_cache 
example : # rm –rf /var/spool/squid 


3. Create a swap again
code :
#squid -z

4. run squid
code :
#service squid start

Squid Delay Pools as a limiter download

Squid Delay Pools as a limiter download
If we want to limit the client in downloading the files with the extension
particular, the use squid delay pools.

How, from the server ClearOS press Alt + F2, enter user = root pwd = your root password,
we do edit via the CLI (Command Line Interface)

code
#vi /etc/squid/squid.conf 



press insert
enter the following syntax:

code:

acl lokal src 192.168.1.0/24 

acl ekstensiblok url_regex -i \.wmv \.mpg \.mpeg \.wma \.wav 

\.3gp \.3gpp \.avi \.dat \.aac \.ogg \.mp4 \.mp3 \.mov \.rar 

\.zip \.7z \.iso \.ace \.exe \.torrent \.mkv \.flv \.rm \.asf 

delay_pools 1 

delay_class 1 1 

delay_parameters 1 15000/1000000 

delay_access 1 allow ekstensiblok lokal 

delay_access 1 deny ALL 

Description:

- src is local ip address your clients, adjust themselves in the sample mean-192.168.1.1

192.168.1.254

- download the file extension you want on the block like the example above, you can reduce or

add their own

- 15000/1000000 delay parameter means that if the file is downloaded already exceed 1MB

then the download speed will drop to 15Kbyte/s.Sesuaikan own parameters according to

you.

Example: if I want to download files. mp3 the magnitude 4MB, then the first time

download will get the maximum bandwidth available, so it reaches 1MB

bandwidth will go down until rata2 15KBps aja until the download is complete.

When finished editing press the Esc

then save with: wq [enter]

restart squid

Code:

# service squid restart

Making Squid cache outside the default directory

Making Squid cache outside the default directory
Squid proxy cache server in ClearOS default located at / var / spool / squid.Jika us
want to use another partition or another hard disk as separate from the squid
system, then inevitably have to replace its cache directory.
The steps are as follows:
1. Create another partition (not a directory / folder you know, but partitions) on my hard drive, for example /    cache
2. Create a large volume, such as Ext3 12GB
3. Give access rights to the partition squidnya

code
# chown squid:squid /cache 



4. Edit the squid.conf file, the cache_dir, change its path to / cache, the other parameters do not need
replaced (if you do not understand the distribution of L1 and L2), let us change it later via
webconfig aja
5. Create swap Squid

code
# squid -z 



6. Login webconfig, adjust the parameters, but remember, the maximum cache size should not
maximized until the cache volume, make it 75% only, eg / Cache = 12GB, maximum
cache sizenya = 9GB
7. Run squid and set it to automatic re-loaded so that if a server restart. activate
transparent if necessary ...
