Advantages of iSCSI Technology
Compared with traditional SCSI technology, iSCSI technology has three revolutionary changes:
The original SCSI used only on the local machine is transmitted through the TCP/IP network, so that the connection distance can be extended in an unlimited region;
The number of connected servers is infinite (the upper limit of the original SCSI-3 is 15 );
Because it is a server architecture, online resizing and dynamic deployment can
algorithm of the temporary port is 204*256 + 73. To better understand the process, we have monitored the data transfer in this process. The following section describes how to use the client to log on to the temporary port.08/24-15:24:24. 052846 0: E0: 4C: F0: E0: Ea-> 0: D0: F8: 51: FC: 81 type: 0x800 Len: 0x4a192.168.10.8: 32791-> XXX.

Next we will start to install adrms. adrms is actually a function built in windows, so we can simply add it to Windows server. Note that adrms must be added to a domain, but do not install adrms on DC. If necessary, adrms can be used as a cluster, but it is rarely used. After adrms is installed, we not only need to implement regular document encryption, but also integrate it with the Exchange Server, restrict email permissions. First, let's look at the configuration of adrms.

Knowledge about cobbler principles
Distribution: Specifies the release version. PXE can only provide one installation scenario for one release version (when kickstart is used)
This is the core component of cobbler.
The definition of distribution is to specify the kernel and ramdisk file (initrd) of a release version to determine which version it is. After installation and startup, you can find the repository, download the components to be installed
Use distribution and repository to define the p

First, I will draw the following topology, which is marked in the basic configuration map of each vro. The loopback ports are added to the three routers, respectively, with the addresses 1.1.1.1; 2.2.2.2; 3.3.3.3. In the subsequent configuration, each route uses its own loopback port address as its own router ID. (To facilitate OSPF region planning and troubleshooting, a loopback port address is usually configured as the router ID of the route. If the router ID or interface address is changed af
