example, assuming that the name server processes queries against USC-ISIC.ARPA, it requires query a information, and the following are the contents of the RR: Usc-isic. ARPA in CNAME c.isi.edu c.isi.edu in A 10.0.0.52 All two RRs are returned as responses, and only the CNAME query returns CNAME. A domain name in a RR that points to another name should point to the primary name rather than the alias, which

In linux, how to add a second IP address to the NIC-Linux Enterprise Application-Linux server application information is as follows. Add an alias (for example, pop) to the network configuration in the graphic interface and bind the alias to the driver of the same Nic. However, you can define another ip address (for example, 33.36.3.6 ), I used very well. Ping this CODE: $ ping pop$64 bytes from pop (33.36.3.6): icmp_seq = 6 ttl = 255 time = 144

The Ubuntu Software Center has just received support from PayPal for the long-awaited payment of the USC 'spayed application by credit card. PayPal supports login. According to Canonical's StuartMetcalfe, "those that do not have a credit/debit card or get their bank's conversion fee for non-local currency transactions are frequently required by users ". Easy to use: navigate to the USC purchase category, lo

All the random crashes of Ubuntu in the latest version no longer exist. What is the performance? I installed Ubuntu 15.10 64-bit, updated everything, and then started running. A week later, I threw away the installed version and installed Ubuntu GNOME 15.10 64-bit. Performance improvement is quite obviou

Here's an excerpt: Alexander Sawchuk estimates that it is in June or July of 1973 when he, then an assistant professor of elect Rical Engineering at the USC Signal and Image processing Institute (SIPI), along with a graduat

ASCII-compatible (that is, the first 128 characters are consistent), but it is not compatible with DBCS because other characters are re-encoded in the UCS (rearranging the location).UCS is available in two formats: UCS-2 and UCS-4. The former is encoded in 2 bytes (16 bits), which is encoded with 4 bytes (actually 31 bits only). USC-4 the first 2 bytes are 0 of the part called BMP (Basic multi-language plane), that is, BMP removal of the first 2 0 by

at the end of a line 3. Cabinet top aggregation (using fiber optics or switches) First, we will introduce point-to-point cabling. This is the cabling method used by the data center over the years, as we have seen before-a mess. Point-to-point means to pull the network cable under the floor, in the air (whether or not there is a cable trough) or through the server Cabinet as long as necessary. Cables are usually made on the spot or directly used with existing links. The old cables are usually no

directions. Use the worst attenuation parameter value to determine whether your link can pass the standard. The installation standards recognize the directionality of tests on optical fibers and provide testing methods. You can splice multiple optical fibers into one Backbone link by using connectors or other methods. TIA/EIA-568-B.1 requires you to test the Backbone link at least once in one direction. In fact, it implies that two-way testing should be a good method ). Based on the same standa

The job of a network administrator is often to diagnose and troubleshoot a variety of server failures. Although no one likes trouble, but trouble always find their own door. Only with superb diagnostic skills can you respond quickly in an emergency and ensure that your network runs smoothly. The following Hengyang high-anti-machine room technical staff summed up some common problems in the server solution, and rented a server friend Exchange.When you're challenged by a network failure, start by

Jumper consists of two parts. One part is fixed on the motherboard, hard disk, and other devices. It consists of two or more metal jumpers (1) and the other part is the Jumper cap (2 ), this is a movable part, the outer is insulating plastic, the inner is conductive material, can be inserted in the Jumper needle above, connect two jumper pins.Figure 1 metal jumper Figure 2 Patch Cord cap When the Jumper cap is buckled on two jumper pins, it is swit

weld the optical fiber cables and pigtails. 3. What is the difference between pigtails and jumpers? Can jumper be split into two parts as pigtails? In fact, both the optical jumper and pigtails are optical fibers! The protective layer of the optical fiber jumper is thicker, which is connected to pigtails and terminal devices.Pigtails are used in the trunk box to connect the optical fiber cables and the flange of the trunk box. Pigtails are used

believes that the advantages of special jumpers mainly have the following advantages: First of all, the special jumper once the electrical performance is higher than the manual on-site production products. The same super five wiring link uses the special jumper and the self-made jumper test respectively, usually its channel performance difference is about 30%. Secondly, the special jumper adopts multi-core core (usually 8 cores) and proprietary core

For Integrated Wiring, telecommunications and equipment are the gathering places of data, voice, and image services. Its importance is self-evident. However, they have made great efforts in their overall design, device finalization, hardware configuration, construction and maintenance, and other aspects. However, the construction party often ignores the maintenance and installation of the largest number of equipment in the telecom and equipment rooms-cables and optical fiber

With the decrease in hard disk prices and the increase in software installation, many people have adopted the method of adding a hard disk to increase the storage capacity. However, the installation of dual hard disks is relatively simple, but there are many things to consider. Based on my own practice, the author puts forward the following points of attention. 1. There are two ide interfaces on the motherboard. Up to four ide devices can be installed. Before installing a dual hard disk, you

system provides reliable solutions The various cables and jumpers in the data center, crowded room space, frequent changes, and continuous connection problems are one of the biggest headaches for IT supervisors. If the number of users increases, you need to constantly add network devices, such as racks, distribution frames, and switches. Not only does the cost increase, but even the unspacious IDC space becomes narrower and more difficult to manage.

Point-to-point means that no matter whether there is a cable trough under the floor or in the air) or through the server Cabinet, the network cable is pulled as long as necessary. Cables are usually made on the spot or directly used with existing links. The old cables are usually not removed or marked, which makes tracing and searching more difficult. As a result, data center personnel need to maintain the cables in a "rat's nest" envir
