Alternatively, you can use the squidclient program that comes with Squid:

% squidclient http://www.squid-cache.org/

CHECK CONFIGURATION FILE

Before trying to start Squid, you should verify that your squid.conf file makes sense. This is easy to do. Just run the following command:

% squid -k parse

Re-INIT CACHE with PROGRESS

Cache directory initialization may take a couple of minutes, depending on the size and number of cache directories, and the speed of your disk drives. If you want to watch the progress, use the -X option:

% squid -zX

EXAMPLE CONFIG SQUID for ACL

(1) To allow http_access for only one machine with MAC Address 00:08:c7:9f:34:41

To use MAC address in ACL rules. Configure with option -enable-arp-acl.

acl all src 0.0.0.0/0.0.0.0
acl pl800_arp arp 00:08:c7:9f:34:41
http_access allow pl800_arp
http_access deny all

(2) To restrict access to work hours (9am – 5pm, Monday to Friday) from IP 192.168.2/24

acl ip_acl src 192.168.2.0/24
acl time_acl time M T W H F 9:00-17:00
http_access allow ip_acl time_acl
http_access deny all

(3) Can i use multitime access control list for different users for different timing.

AclDefnitions

acl abc src 172.161.163.85
acl xyz src 172.161.163.86
acl asd src 172.161.163.87
acl morning time 06:00-11:00
acl lunch time 14:00-14:30
acl evening time 16:25-23:59

Access Controls
http_access allow abc morning
http_access allow xyz morning lunch
http_access allow asd lunch

This is wrong. The description follows:
Here access line “http_access allow xyz morning lunch” will not work. So ACLs are interpreted like this …

http_access RULE statement1 AND statement2 AND statement3 OR
http_access ACTION statement1 AND statement2 AND statement3 OR

……..

So, the ACL “http_access allow xyz morning lunch” will never work, as pointed, because at any given time, morning AND lunch will ALWAYS be false, because both morning and lunch will NEVER be true at the same time. As one of them is false, and acl uses AND logical statement, 0/1 AND 0 will always be 0 (false).

That’s because this line is in two. If now read:

http_access allow xyz AND morning OR
http_access allow xyz lunch

If request comes from xyz, and we’re in one of the allowed time, one of the rules will match TRUE. The other will obviously match FALSE. TRUE OR FALSE will be TRUE, and access will be permitted.

Finally Access Control looks…

http_access allow abc morning
http_access allow xyz morning
http_access allow xyz lunch
http_access allow asd lunch
http_access deny all

(4) Rules are read from top to bottom. The first rule matched will be used. Other rules won’t be applied.

Example:

http_access allow xyz morning
http_access deny xyz
http_access allow xyz lunch

If xyz tries to access something in the morning, access will be granted. But if he tries to access something at lunchtime, access will be denied. It will be denied by the deny xyz rule, that was matched before the ‘xyz lunch’ rule.

FOR LIMIT DOWNLOAD AND UPLOAD

Tag Name request_body_max_size
Usage request_body_max_size (KB)

Description
This specifies the maximum size for an HTTP request body. In other words, the maximum size of a PUT/POST request. A user, who attempts to send a request with a body larger than this limit receives an “Invalid Request” error message. If you set this parameter to a zero, there will be no limit imposed.
Default request_body_max_size 1 MB

Tag Name reply_body_max_size
Usage reply_body_max_size (KB)

Description
This option specifies the maximum size of a reply body. It can be used to prevent users from downloading very large files, such as MP3′s and movies. The reply size is checked twice. First when we get the reply headers, we check the content-length value. If the content length value exists and is larger than this parameter, the request is denied and the user receives an error message that says “the request or reply is too large.” If there is no content-length, and the reply size exceeds this limit, the client’s connection is just closed and they will receive a partial reply.
Default reply_body_max_size 0
If this parameter is set to zero (the default), there will be no limit imposed.

Caution
Downstream caches probably cannot detect a partial reply if there is no content-length header, so they will cache partial responses and give them out as hits. You should NOT use this option, if you have downstream caches.

Ctfmon is the Microsoft process that controls Alternative User Input and the Office Language bar. It’s how you can control the computer via speech or a pen tablet, or using the onscreen keyboard inputs for asian languages.

If you are using any of the above, you should leave it enabled. For everybody else, we’ll get to the job of disabling this annoying service.

You can just completely unregister the dlls that run the alternative input services by running these two commands from the run box (one at a time)

Regsvr32.exe /u msimtf.dll

Regsvr32.exe /u msctf.dll

find . -name "FILE-TO-FIND"-exec rm -rf {} \;

OR

find . -type f -name "FILE-TO-FIND" -exec rm -f {} \;

The only difference between above two syntax is that first command can remove directories as well where second command only removes files.

More Examples of find command

(a) Find all files having .bak (*.bak) extension in current directory and remove them:
$ find . -type f -name "*.bak" -exec rm -f {} \;

(b) Find all core files and remove them:
# find / -name core -exec rm -f {} \;

(c) Find all *.bak files in current directory and removes them with confirmation from user:
$ find . -type f -name "*.bak" -exec rm -i {} \;

Now your browser should be faster but if you want to “go over” then you should try this little extension that speed up Firefox startup: Chrome Cleaner.

Restart your browser and go to (actually I’m not using the English version so I’m sorry if the following path it’s not 100% exactly!) “Tools” > “Add-Ons” > “Chrome Cleaner” > “Options” and then click on the “Clean!” button. Done!

Mounting samba bisa dilakukan secara manual menggunakan konsole. Meski terbilang primitif , cara ini kadang diperlukan untuk memastikan apakah ada suatu kesalahan pada baris perintah yang kita lakukan.

Mount pada folder yang hanya bisa diakses oleh user tertentu (butuh user name dan password)
mount -t cifs //NamaServerSamba-AtauIPAddressSamba/NamaShare /FolderUntukMount/NamaFolder -o username=UserSamba,password=PasswordSamba,iocharset=utf8,file_mode=0777,dir_mode=0777

Contoh :
mount -t cifs //192.168.0.1/Warehouse /home/vavai/Desktop/whs2 -o username=vavai,password=passwordvavai,iocharset=utf8,file_mode=0777,dir_mode=0777

Penjelasan :
- mount -t cifs adalah perintah untuk mount folder Samba. Jika menggunakan distro lain bisa diganti dengan perintah mount -t smbfs

- 192.168.0.1 adalah IP Address Server Samba. Jika menggunakan Nama HostName / Netbios, kita perlu melakukan setting pada file /etc/nsswitch.conf. Ini belum saya bahas pada panduan ini

- Warehouse adalah nama folder share. Nama folder share pada suatu komputer dapat dicheck dengan perintah smb://ip-address-server-samba pada Konqueror

- /home/vavai/Desktop/whs2 adalah nama folder tujuan untuk proses mounting. Folder ini harus sudah ada. Jika belum ada ya harus dibuat.

- -o username=vavai,password=passwordvavai, adalah nama dan password user samba

- iocharset=utf8, untuk memastikan proses konversi huruf / font. Pada komputer dengan font non latin, ada masalah jika opsi ini tidak didefinisikan.

- file_mode=0777,dir_mode=0777, perintah untuk memastikan bahwa folder atau file yang dibuat pada hasil mount bisa diakses dengan modus read dan write.

Cara ini memiliki kekurangan karena username dan password samba dibuat secara plaintext yang artinya bisa dilihat oleh orang lain dengan mudah. Untuk melindunginya, kita bisa menggunakan opsi file credentials, yang menyimpan user name dan password pada suatu file teks yang diletakkan difolder tertentu dan hanya bisa diakses oleh user tertentu.

Caranya adalah dengan membuat file teks, misalnya root/.filecredentials. Tanda titik pada file menunjukkan bahwa file ini berjenis hidden file. Buatlah file tersebut dengan text editor non GUI, misalnya dengan vi. Kenapa tidak dengan GUI Editor, karena file ini harus berisi perintah teks murni tanpa format macam-macam. Isilah file tersebut dengan isi sebagai berikut

username=UserSamba
password=PasswordSamba

Lakukan chmod pada file tersebut agar hanya root yang bisa mengaksesnya, chmod 700 /root/.smbcredentials

Mount pada folder tanpa user name dan password :
mount -t cifs //NamaServerSamba-AtauIPAddressSamba/NamaShare /FolderUntukMount/NamaFolder -o guest,rw,iocharset=utf8,file_mode=0777,dir_mode=0777
Mount dengan akses read only
mount -t cifs //NamaServerSamba-AtauIPAddressSamba/NamaShare /FolderUntukMount/NamaFolder -o guest,iocharset=utf8
