In turn, the shell is, in fact, what humans tell the machine at some point, what it does, what it does, and what it does, except that the operating system is made up of the basic elements of the file. Therefore, the shell is to find the required files, that is, what behavior to use.　　And a certain moment, the completion of what can be understood as parameters, to achieve the effect depends on the user's familiarity with a variety of commands, because a number of commands (a number

The first time in 51 to write a blog, is my beauty, I hope this is a good start.The university is not the computer, so how much in later work there are a variety of problems. But this is not the key to stop me from learning the skills. The first contact is due to my eldest brother's recommendation to my "bird Brother Linux Private Dishes", remember the beginning of college contact, look at those things are very strange, even the basic installation system is very difficult, can not tell the Linux

involved in the SAV mentioned above to read-only and cannot be changed. This problem can be solved temporarily.Figure 4In addition, you can use tools such as setacl.exe 0.904 and regini to set Registry Permissions. The SetACL tool is recommended here. If you have learned CCNA, you should know that ACL is the meaning of the access control list. This tool can not only set permissions for the Registry, but also set permissions for files (folders), simil

routing protocol? The link status routing protocol is more suitable for large networks. However, due to its complexity, the router needs to occupy more c p u resources. It can detect broken links or new routers in a shorter period of time, so that the convergence time of the Protocol is shorter than that of the Distance Vector routing protocol. Generally, if you do not receive the ccna Examination Report from the neighboring station within 10 seconds

At present, the demand for Routing Switching equipment is very high in the market, especially in enterprises. It can be seen from the data that the performance of Routing Switching equipment is also gradually improving. The vro and vswitch password recovery methods must be mastered by the network administrator. These contents are displayed in the CCNA courses. However, from the description of this user, we can see that the model of the routing switch

RIP, it selects an OSPF route. Because the OSPF management interval is 110, and the RIP management interval is 120. Here is another example: for example, if your vro receives a route from Internal, its management interval is 90, But you accidentally input a static route to an IP address, the Gap Management address of this IP address is 1. The vroeigrp uses a static route instead of an IPsec route. The last point is to emphasize that the management interval is the focus of the

Many people may not have a special understanding of juniper enterprise-level routing. Next we will give a comprehensive introduction to juniper enterprise-level routing certification, so that you can have a better understanding of juniper routing. Juniper network, a high-performance network leader, today announced the launch of the juniper enterprise-level route certification shortcut plan in the Asia-Pacific region, which is expected to end by December 31 this year from now on.

powerful it can protect your servers and data. Many ISPs and websites in China may not pay much attention to this aspect. bosses pay more attention to the bandwidth of several megabytes. Once your server is inaccessible, you will pay dozens of times the cost. In fact, it takes only a few hours or a few dollars to pay for the software. In fact, finding someone who will configure ssh or vpn will not be much more expensive than ccna. But speaking of th

time, I had to learn by myself. I think it would be more difficult. I went to my brother's college to listen to some courses, went to the enterprise to attend some training, and also heard beiyou's teacher talk about courses such as ccna, and had a consensus with them: if the students can understand the content within an hour, the teacher does not need to spend two classes in the class to introduce it. This is too inefficient, this learning method ca

Before you get started, I 'd like to point out a couple of things to keep in mind: NTP is a slow protocol, and the formation of NTP associations can take a long time. So, don't expect CT anything to happen fast. You can keep an eye on it usingDebug NTP Set of commands. If you decide to use an Internet NTP server, make sure you open UDP port 123 inbound on your firewall to yo

However, some of them also raise the TCP/P basis, the content regulations are clear, and the method of analyzing the definition is easy to get in love. Even if your curre
