Here is because I need to do a bug with contact SELinux, so I looked for a lot of information to learn.The whole half a month of my problem, finally resolved, so hereby to record, also learn. Here I will summarize some of the recent query summary of the data then the collation of a lot of information, many are reproduced from the Internet, some of their additions, for future standby, but also for everyone to learn Kazakhstan. Here this background, I put some links, after all, this can slowly un

Label:Stored procedures created using the WITH ENCRYPTION option in SQLSERVER2005 are still encrypted with XOR, as in sqlserver2000. Unlike 2000, encrypted ciphertext has not been found in the system table syscomments of 2005. To check ciphertext after you have connected to the database using a DAC (dedicated Administrator connection), in the system table Sys.sysobjvalues query, the table column Imageval stores the corresponding ciphertext.

The network center uses the RHS4616GMS full-gigabit managed optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entir

With 500 computers, the Gigabit Optical Fiber switch solution is required. Internet cafes need to support port mirroring, port aggregation, QOS, and other functions of the Gigabit Optical Fiber switch, to meet different network application requirements. Internet cafes with a large number of computers should also have other solutions. 300-about 500 Internet cafes The network center uses two RHS4624GMS fully Gigabit managed Ge Optical Fiber switches for 10 Gigabit cascade. It can provide 32 Gigabi

managed Internet cafe optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entire Internet cafe. It also supports ARP security, port VLAN, and 802.1 QVLAN, Port Mirroring, port aggregation, QOS, and other functions to meet different network application requirements. 2. Eight

Optical fiber is generally made from Z (SiO2) after special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals, it features high bandwidth, large transmission capacity, low signal loss, and long transmission distance. Therefore, the emergence of the Internet cafe Optical Fiber solution will undoubtedly bring a spring breeze to the entire Internet cafe. The development of the Internet cafe industry has gone through countless leaps an
