The web technology has been one of the most rapidly developing fields of technology. Just from static simple html web pages who could do nothing except delivering you information, the web pages have evolved to the extent that today’s web pages even remembers your password and which computer you logged in last time and several other data. So, as the technology flourishes so do its problems and drawbacks. There are several problems prevalent today which might arise in your web browser. Sometimes they become so severe leaving no option for you other than uninstalling it. But if you’re an Internet Explorer user, you have another option called resetting its settings. Resetting Internet explorer will bring it to the condition and state similar to the day when you freshly installed your operating system. All settings will be removed, all passwords and history of web pages will be erased, but you can be happy that your favorites or your feeds or web slices will be there as they were. They will remain unaltered and unchanged. Rest everything you will have to start it all over again. But it will at least offer you a good option during troubleshooting. One other point is that once you opt for resetting your Internet explorer, you can’t undo your action. It is irreversible and all data along with the settings will be lost. There will be no more prompting of web URL’s or even email addresses or any other assistance. You will have to configure your browser all over again. Taking an elaborated look at the settings which will be deleted, we can conclude that the toolbars or add-ons which you had disabled will be gone, the settings which blocked certain websites or trusted zones will be effaced, security settings , advanced settings, home page, etc will be set to default and settings of pop-up blocker will be wiped off. Settings that remain as it were are proxy and VPN settings, certificate information, Favorites, feeds, web slices, etc. read all instructions carefully before you go for resetting so that you can configure your Internet browser as is was in your personalized settings. To perform resetting of the Internet Explorer 7 or 8 you have to follow some very easy steps as mentioned below: First of all close all windows explorer windows or other Internet explorer windows and start the Internet explorer from start menu by clicking on start button. You will have a menu in the top part of the window, if you don’t have press’ Alt key’. Once you have it click on tools and go to ‘Internet Options’. There you will have several tabs, browse to ‘Advanced tab’ and click ‘reset’ there. If you opt for ‘deleting personal settings’ by checking it, it will remove all entries of home page, download history, searches, etc. Then in the dialog box called “Reset Internet Explorer settings”, click on Reset. And there you go, your browser will be reset and once it completes click on ‘Close’ and then ‘OK’. Close Internet Explorer settings and restart it. All new settings will be applied. As mentioned earlier, be careful before resetting the settings and make yourself aware of all consequences which will arise after that. After all we don’t want the troubleshooting process to become troublesome.

L2-L4 layer filter New switch now rule most of the way through the establishment of a variety of filtering needs to achieve. Rule set has two modes, one is MAC mode, the source according to user needs based on valid MAC or destination MAC for data isolation, the other is the IP model, can be the source IP, the purpose IP, protocol, source application port and Objective port filtering data packets; establish good rules must be attached to the corresponding receive or send port, then when the switch this port to receive or transmit data, according to filtering rules to filter packets, the decision is forwarded or discarded. In addition, the switch via hardware “logic and non-gate” to the filtering rules of logic operation, determined to achieve filtering rules, and not affect the data forwarding rate. 802.1X port-based access control To prevent unauthorized users access to the local area network to ensure network security, port-based access control protocol 802.1X wired LAN or WLAN in terms of both widely used. For example, a new generation of ASUS latest GigaX2024/2048 products not only support the 802.1X switch the Local, RADIUS authentication, and support the DynamicVLAN 802.1X access, that VLAN and 802.1X based on accounts held by a user users regardless of where within the network access, will go beyond the original 802.1Q Port-based VLAN, under the restrictions, has access to this account within a specified VLAN group, this feature not only for mobile users within the network application of resources provides convenience and flexibility, while applications to protect the security of network resources; addition, GigaX2024/2048 switch also supports 802.1X’s GuestVLAN function, that the application of 802.1X, if the port specified GuestVLAN item, under the port access into the user if authentication fails or if not free user account, will be GuestVLAN group members can enjoy this group to the corresponding network resources, such a function can also be applied for the network open to certain groups of minimum resources, and to the network provides the most secure external access. Flow control (trafficcontrol) Switch flow control can be prevented because the broadcast packets, multicast packets and error because the destination address unicast packet switch bandwidth of data flow anomaly caused by excessive load, and improve overall system performance, maintaining network security stable operation. SNMPv3 and SSH SNMPv3 security network put forward a new architecture, will focus on all versions of SNMP standards together, thus enhancing network security. SNMPv3 security model proposed is based on the user’s security model, that USM.USM messages on the network encryption and authentication is based on users, and specifically, what protocols and keys for encryption and authentication by user name (userNmae ) authoritative engine identifier (EngineID) to decide (recommended encryption protocol CBCDES, authentication protocol HMAC-MD5-96 and HMAC-SHA-96), through authentication, encryption and time to provide data integrity, data origin authentication, data confidentiality and message time services, so as to effectively prevent non-authorized users to manage information changes, camouflage and eavesdropping. The remote network management via Telnet, Telnet service as a fatal weakness?? It is transmitted in clear text user name and password, so it is easy to steal passwords by people with ulterior motives, being attacked, but were using SSH communication, the user name and password are encrypted, effectively prevent eavesdropping on passwords, network management personnel to facilitate the safety of remote network management. Syslog and Watchdog Syslog logging can switch the system error, system configuration, status changes, state periodic report, the system set out the expectations of other users to log messaging server, network management personnel based on that information to master the operating conditions, early problems are identified, timely configuration and troubleshooting to ensure network security and stability in operation.

Copyright (c) 2007 Thomas Husnik With the extent with which we use computers today ‘ for both professional and personal use ‘ it’s safe to say we’ve all encountered the need for computer repair in some form. Whether it’s spyware or a network crash, computer repair is what can save us from slowed computer performance, corrupted files, data loss, and time wasted. Not surprisingly, the birth of computer repair coincided with the rise of computer use. A complicated piece of technology, a computer is nonetheless used by most of us daily. We sit down at our computers and effortlessly check our emails, stock quotes, and the latest news. We research showtimes and restaurants. We work our 9 to 5 jobs, using laptops, virtual communication, and handheld devices. Indeed, much in our lives revolves around the computer. It’s no wonder why computer repair is so valuable a solution and for the technician, a coveted skill. Given the many uses for computers, there are as many potential problems, errors, and failures. Thus for computer repair, there are at least as many possible fixes. As a result, knowing what to do to fix your computer can seem like an impossible task. However, if you think about it, most of us have picked up a few tricks along the way that have proven effective. For smaller problems, computer repair is entirely possible by ourselves. For more serious problems though, consulting a professional is the best route. The main reason why professionals should be consulted is because a person could do more damage to a computer by trying to fix an unknown problem on their own. To avoid such mishaps, it’s best to ask an expert to take a look. Pinpointing the problem is really the biggest part of any computer repair, as it will reveal the exact fix that’s needed to get the system working properly again. For computer repair technicians, this is the main aspect of their service. Diagnostics do not have to be performed in person necessarily, as most computer manufacturers and Internet service providers have call centers for troubleshooting and offer their advice over the phone, via live chat, or email. Business-wise, most companies have a tech-support staff that can help with most problems, from email to lost files. Computer repair can be as simple as choosing different settings to full-on data recovery using involved techniques such as zero-knowledge analysis. Given that most computer technicians are specialized, the chances are good that a team can help with all your problems: viruses, spyware, firewall protection, virtual private networks (VPN), emergency data recovery, RAID recovery, system upgrades, etc. Computer repair pertains to both hardware repair and software repair. At times, installation or uninstallation of software is needed. At others, a small adjustment to preferences will solve the problem. Again, computer repair is wide-ranging. Desktops, mainframes, and supercomputers can all encounter similar problems, but on a different scale. Portable devices will also have related problems, but knowing the system inside a laptop or notebook is a bit different than a PC. This is the reason why most companies have a number of technicians on staff, as one may be more specialized in one area of computer repair than another. Computer repair can be as basic as rebooting your computer, but it can also be as complex as taking the entire system apart. Overall, the service of computer repair is relatively new, but the demand for it is growing at a rapid pace. Naturally, the aim is to keep up with all of the new advancements in computer technology ‘ which seemingly change by the day.
Modern VPN and web session technologies allow you to receive ERP remote support and by attending the same session as your supporting technician, you can communicate on what is the problem plus contribute to problem resolution scenario. In fact, it is even better to have somebody, who supports multiple SB1 customers nationwide and aware about all the potential problems and known cases, than somebody who serves you locally, but have to do very different implementation assignments every new day. Let’s review remote connection and support techniques: 1. VPN or virtual private network. This technology could be realized in hardware or in software. Hardware option is when your router supports VPN and software is when you enable VPN on one of your servers. Having VPN connection channel, SB1 support engineer connects to your network and use remote desktop connection to your application server to work with SAP B1 application. Please, note that in VPN connection you do not share the same screen with supporting technician as you do in web session 2. Web Session. Popular options are WebEx and Gotomeeting. These technologies allow you to see the screen of each attendee, where you can switch attendee desktops as needed. Plus, you use either hosted by web session provide conference phone number, of use popular voip technologies such as skype. Skype is especially popular in international support environments, where regular phone calls might be too costly 3. SAP Business One support specifics. SB1 is self contained application, which does not require tight integration with peripheral technologies, and so it is very convenient in remote support, at it doesn’t require synchronous involvement of your IT people 4. Remote centralized deployment. We recommend remote ERP installation, initial data conversion, modules and system settings and then transferring and implanting it onsite on your SQL Server. This streamlines the installation and implementation phase
