1.ASA Security Level
By default, the Cisco PIX firewall applies security levels to each interface. The more secure the network segment, the higher the full level. Security levels range from 0~100, by default, security level 0 is adapted to E0, and its default name is external (outside), and security level 100 is suitable for E1. And its default name is inside. Use the name if to configure any additional interfaces, security levels in the 1~ Between 99

This document describes the IPSec configuration between the router and the Cisco firewall. The traffic between the headquarters and the branch office uses the private IP address, when the branch's local area network user accesses the Internet, needs to carry on the address conversion.

Configuration
Define the traffic to the router:
Access-list IPSec permit IP 10.1.1.0 255.255.255.0 10.2.2.0 255.255.255.0

The difference between sleep () and wait () is that the wait () method is unlocked when invoked, but where we can use it is only in a synchronized method or block of code.

Static outside IP_Address inside IP_Address
11. Set some control options:
Conduit GLOBAL_IP Port[-port] Protocol foreign_ip [netmask]
Global_ip refers to the address to be controlled.
Port refers to the ports that are acting, where 0 represents all ports
Protocol refers to the connection protocol, such as: TCP, UDP, etc.
FOREIGN_IP represents an access to GLOBAL_IP's external

Logging Sybase error messages
When used in conjunction with Heartsone backup™ Backup and Recovery software, Sybase records all information in a private log file. During backup and restore operations, Heartsone backup™ intercepts log information related to the current task and sends a copy to the Heartsone backup™ log, which is displayed along with other Heartsone backup™ task information.

to learn a programming language before learning a database?
The answer is not required, but by the TL _sql, which helps to learn SQl, has a circular command.

The database is at the application level, studying the error and operation
Data structure in the system software level of vision of the error and operation,
are different levels of the problem

Message exchange is the only means for WCF to communicate, the service access required by means of call is translated into specific messages and encoded (Encoding) to be sent to the server via the transport channel. The results of the service operation execution can only be returned to the client in the form of a message. As a result, messages are at the core of the entire WCF architecture, and WCF can be viewed as a conduit for message processing.
