Linux firewall named FLOPPYFW can be stored in a normal floppy disk and run independently in RAM memory. It enables you to start your computer, use IPChains to filter out unwanted IP packets, and use it to configure IP camouflage (IP masquerade), the monitoring port, through which you can use the host to remotely control computers in other networks. The FLOPPYFW function is very powerful, but it requires a very low hardware environment, in addition to a floppy disk, as long as 8MB of memory is

Found another Mac closer to the conflicting Mac, this Mac LAN only two, what is this device? On the IEEE Web site to find out that it is 3Com equipment, thinking of 3com equipment, the company has access to only a few switches, is it it? So, open IE, even one of the IP, opened! Sure it is!

With the development of the exchange industry, many new products have emerged. Among them, the Core routing switch is one of them, and it supports high-performance 10-Gigabit interfaces to improve the overall efficiency of the network. Quidway S8500 series 10-Gigabit core route switch is a new generation high-performance 10-Gigabit core route switch developed by Huawei 3Com, it can be widely used in the core layer of the E-government network, the core

With the development of China's routing industry, Gigabit Routers have become one of the mainstream products in the market. It is also a good product for Internet cafes. ER5200 is a dual-WAN port high-performance gigabit router customized by Huawei 3Com for Internet cafes. It uses a professional 64-bit dual-core network processor and features a clock speed of up to 500 MHz, it also provides a wide range of proprietary features for Internet cafes. It i

internal network of the enterprise, check emails, use the Internet, and listen to voice mails through a connection established on the POTS online. In addition, after the voice or email is checked, remote users can connect to the phone number connected from the PC. The cost saved by this function and the increased employment opportunities will make the enterprise more competitive. Simple upgrade and scalability-because Total Control VOIP is a software solution built on the Total Control server,

Currently, most Internet cafes have around 200 servers and are still in a MB network environment, which cannot meet the needs of Internet cafe guests. Internet cafe owners are actively considering upgrading and resizing their own Internet cafes. The key to upgrading internet cafes is network switches. Here I recommend the famous NT series of "Gigabit popularity pioneer" speed technology for Internet cafe owners.SpeedNetworks NT series private switches have five advantages over similar switches:1

(SMEs). These products generally provide four or eight telephone relay interfaces and simple routing functions and network interfaces, the telephone switch or group phone of an enterprise branch can be easily connected through an IP network. For small and medium-sized enterprise users, VOIP gateways of major manufacturers such as CISCO and 3com are expensive and difficult to accept. The functional performance of VOIP gateways of some domestic manufac

Virtualization Unified Messaging (UM) refers to the combination of e-mail, voice, and fax in the same mailbox. Unified Communication (UC) integrates UM with conference, cooperation, and attendance management, they present more possibilities of virtualization. For IP technology, UM and UC functions are similar. UM and UC servers are not constantly busy, so they are not fully utilized during the operation cycle. Virtualization can be applied to UM and UC support. VoIP virtualization platform As I

For our user groups, how can we prevent the strong intrusion of network hackers? Here we will take 3Com as an example to see how they implement network defense. How can users reduce or even eliminate the risk of hackers entering Wi-Fi or 802.11 standard Wireless LAN? First, you must control the qualifications for entering the network, that is, authentication. Second, protect the information sent in wireless mode, that is, data encryption. The followin

networks earlier and use network devices as products of other vendors. Later products cannot be unified with those of earlier stages. In this way, some problems may occur in VLAN division.For example, VLAN is divided in the hybrid network structure of Cisco products and 3Com products. For the Trunk Encapsulation Protocol of Cisco network devices, 802.1Q must be used for communication with 3Com. Although no

. Authentication Sever can adopt standard Radius Authentication Server or service switch. The latter is mainly used in scenarios with a small network size (about 300 users, in the new software version, the Quidway 3000 and later vswitches of Huawei 3Com all provide the built-in Authentication Sever function, the user authentication configuration function is efficiently completed through the internal cluster communication protocol of Huawei

the device. In fact, the Gigabit Switch is now available in many brands to meet these requirements. Such as SpeedNetworks, TP-LINK, Huawei 3COM, Cisco, etc. In the face of these many products, what are the unique highlights of GE switches in terms of technology implementation, product form, and functional features, then, how do users select a Gigabit Switch product that is more suitable for their networks? Some may think that the Gigabit Switch in th

Multiple port listening configurations clear technical barriers for you. Port Monitoring configurations for Cisco 3Com Avaya Huawei and other vswitches are described below. In the 3COM Switch user manual, port monitoring configurations are called "Roving Analysis ". The listening Port is called the "listening Port" Monitor Port), and the Port connecting to the listening device is called the "analysis Port"
