Tôi giới thiệu Squirrelmail v1.4.4
Đây là vesion mới nhất, bạn có thể download trên net hiện tại (20/05/2005). Squirrelmail (SM) cực kỳ dễ dùng, setup dễ dàng, đặc biệt không yêu cầu Database.
 
Nhưng yêu cầu Server phải support IMAP, SM chỉ làm việc theo chuẩn IMAP (bắt buộc server phải có cài 1 dịch vụ IMAP, không phải POP3).

Nếu Server của bạn support IMAP, xin hãy đọc tiếp.

Sau khi download SM, bạn giải nén xong, tìm thư mục DOC để xem hướng dẫn setup.
SM rất dễ setup, chỉ cần bạn tìm file CONFIG.PHP trong thư mục CONFIG, thiết lập các thông số về Server, xong tải lên server là xong.

Basic SSH Commands  Commands used for webhosting providers, and those with cpanel.
Some of these commands are NOT basic linux commands, they are only available for users with CPanel or those who have installed certain scripts for monitoring their website, or to assist them in running their webhosting business. So if some of these commands do not work, please take note this is normal and you probably don't have the software required installed on your dedicated server.

1.  I just uploaded/moved some files to a customers/user of mine and now they can't modify/rename/delete this file?
o  This is because you uploaded the file as a different user/root.
o  Login to your server via SSH & Type: /scripts/chownpublichtmls

SIM (System Integrity Monitor)  
Install System Integrity Monitor

SIM is a system and services monitor for ‘SysVinit’ systems. It is designed to be intuitive and modular in nature, and to provide a clean and informative status system.
It does this by consistently verifying that services are online, load averages are in check, and log files are at reasonable sizes. Many other SIM modules sport different and in-depth features to bring a well rounded tool to your disposal to stop otherwise common issues daunting internet hosts.
1.   Login to your server via SSH as root.

2.  Type: wget http://www.r-fx.org/downloads/sim-current.tar.gz
This will download the most current version of SIM (System Integrity Monitor)

3.  Type: tar -xzvf sim-current.tar.gz
This will extract the tar.gz file at once.

Chào các bạn!
Với dân Webmaster, cPanel đã không còn quá xa lạ. Nhưng chưa hẳn bạn đã sử dụng hết các tính năng của cPanel và thực sự làm chủ nó. Mình cũng chưa làm chủ được tất cả. Nhưng nhờ google. Đôi khi mình cần gì đều có thể có kết quả. Hôm nay lang thang tìm một cái User Guide dành cho người dùng cuối của cPanel. Tình cờ mình tìm thấy một loạt bài Tutorials viết về cPanel. Toàn bộ bài viết trong chuyên trang cPanel Tutorials này được mình lấy từ WebHostGear. Các bạn cũng có thể truy cập trang web trên để tìm thêm nhiều điều bổ ích hơn nữa.

Hiện chuyên trang này đang có 27 bài viết bao gồm cả hướng dẫn sử dụng và phần lớn là các bài viết về Secu cpanel. Mình sẽ Update thường xuyên và nếu rỗi mình sẽ dịch qua tiếng Việt cho các bạn tham khảo. Có điều mình vẫn muốn các bạn sử dụng tiếng Anh ^^.

Chúc các bạn thành công và làm chủ được cPanel

Learn how to assign reseller accounts with their own private name servers such as ns1 and ns2 for their own clients in WHM.
Resellers can also have their own private name servers for their own clients making the server provider more anonymous and the reseller more credible.

Lets Begin!
We assume that you have already setup your resellers account and that you want to just add private name servers for them.
A guide on setting up reseller accounts will be provided soon in the Cpanel Tutorials section.

What You Need
2 free ip addresses
WHM root access to the server

Since the beginning of time, cPanel has had logs that it simply does not rotate properly. Why this has been an ongoing problem that has never been fixed is beyond me, but it CAN be fixed and we'll go through what is needed to accomplish this.

The most important logs that are missed are the Apache system logs that are located in /usr/local/apache/logs. SSH into your server as root.

pico /etc/logrotate.d/httpd
(on some servers this file is called apache)

The first line should read:

/usr/local/apache/logs/*log {

Also you need to change the line that reads:

What is BIND?
BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name System (DNS) protocols and provides an openly redistributable reference implementation of the major components of the Domain Name System, including:

- a Domain Name System server (named)
- a Domain Name System resolver library
- tools for verifying the proper operation of the DNS server

The BIND DNS Server is used on the vast majority of name serving machines on the Internet, providing a robust and stable architecture on top of which an organization's naming architecture can be built. The resolver library included in the BIND distribution provides the standard APIs for translation between domain names and Internet addresses and is intended to be linked with applications requiring name service.

Why hide the BIND version number?
Although hiding the BIND version number will not prevent automated cracking tools from exploiting vulnerable nameservers, you should prevent "banner grabbing," or allowing others to gather version information about services running on your machines. This is no substitute for keeping your BIND version updated. You must keep your server updated to be protected from the latest security threats and exploits. If a hacker runs an exploit on your outdated version of BIND, even if you hide the version number, you will get hacked into.
