Okay, everybody.This weekend seems to have been very fast, because there are too many customers after-sales problems need to actively cooperate with the processing, in short, the time for engineers to do a good job of technology has gone, many times we have to assume too many original role, and not just Huawei, China three, Cisco.this share, but also focused on the configuration of the idea of Huawei, rock Mesh firewall configuration ideas, in favor of everyone comprehend by analogy, spend a few
What the hell is a sub-interface? I explain too much here that if you do not understand one-arm routing, please "repair your homework", it will be easier to understand the SSG series configuration details and problems.Next, in the Common enterprise network, many have some "unprofessional" network and network management to do some simple rough network, such as switch all when pure two-layer fool to use, all the gateways are in the export equipment, in

As noted in the previous entry, you can increase this with the Envar, but you need to use them in multiples of 8, and the combination of cluster ID ' s and VSD ' s cannot exceed . Y
Problem description:
When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files.
Problem Analysis:
These problems are often caused by the identification of data packet fragments by devices during data transmission. Generally, data packets are too large and nee
SSG-5 is the Juniper Firewall entry level products, some emergency situations need to log into the intranet of a PC or server, need to temporarily open the firewall 3389 ports and do the corresponding VIP mapping.

There are some small rivers and some lakes on the campus of Nanyang Institute of Technology. Now we take them all as pools. Su
To a certain extent, the pool technology can significantly optimize the performance of server applications, improve program execution efficiency and reduce system resource overhead. The pool mentioned here is a pool in a broad sense, such as the database connection pool, thread pool, memory pool, and Object pool. The object pool can be seen as a container for saving objects. A certain number of objects are created during process initialization. When needed, a free object is taken directly from t
of this time, you can avoid this error!
The core of IIS 6 is worker process isolation mode , and the application pool defines how the worker process works, so that the application pool is the core of the entire IIS 6.
Unlike IIS 5, which uses only a single application pool, IIS 6 working in worker process isolation mode can create multiple application pools, which are completely isolated from each other, and no application pool will be affected by

This method can greatly reduce the complexity of transaction management.4.

Reasonable Allocation and release can increase the reusability of connections, reduce the overhead of establishing new c

When IIS 6.0 is running in worker process isolation mode, you can combine WEB applications into application pools. Application pools allow specific configuration settings to be applied to multiple application groups and allow worker processes to service these applications. You can specify any Web directory or virtual directory to the application pool.
