Malicious Software infected MySQL servers as part of the global DDoS botnet
Symantec has discovered that attackers use malware to hijack the MySQL server, add it to the global DDoS botnet, and then launch a DDoS attack. According to Symantec, attackers can use SQL injection (unconfirmed), use a special UDF (User-Defined Function) file to infect the MySQL server, and then save Downloader on the server. ch

The following describes the installation of Ralus (the Legacy agent is now rarely used, and is not introduced)
The following assumes that your media server (the backup server that is installed with Backup Exec) has already been installed and has the Ralus option installed.
First, the Ralus installer is large and is provided on a separate disc. If you do not have a CD, you can also download it via the

The split package does not insert other data.
Therefore, to use socket communication, you must define a protocol. Currently, the most common protocol standard is: Message Header (Baotou) + message length + Message BodyWhy is TCP subcontracting?
TCP sends data in segments. After a TCP link is established, there is a maximum message length (MSS ). If the application layer data packet exceeds

The network packet size and transmission speed are useful in UDP and almost useless in TCP. For example, if MTU in Ethernet is 1500 and valid data of a packet sent in UDP is 10 bytes, a packet must have 20 bytes of IP header, for 8-byte UDP headers, the valid data rate sent over the network is 10/(20 + 8 + 10). If-20-8 bytes of valid data are sent, then the valid data rate sent over the network is (1500-20-8)/1500, which means the efficiency is high, however, if the size of the data sent is larg
BGP protocol-neighbor PMTU checks that the BGP protocol runs on TCP, so the TCP parameter settings will affect the performance of BGP. When the number of routes is small, the adjustment of TCP Parameters may not affect the BGP performance. However, when the number of routes is large, the adjustment of TCP Parameters can optimize the performance. Next, we will analyze the specific optimization methods. First, let's take a look at the BGP protocol packet sending method. See: BGP and TCP data trans
successfully sent or accepted. ------------- TCP-------------1. TCP is connection-oriented and provides full duplex services, that is, TCP connections are bidirectional and point-to-point. Three handshakes are required to establish TCP. The sender transmits data to the TCP sending cache through a socket. When the data reaches the maximum message length (MSS) TCP adds a TCP header to the cache to form a packet segment and sends it to the receiver's TC
, but tend to linear growth, in order to avoid network congestion, this stage has a number of algorithm implementations, usually keep the default, here is not explained.? How to adjust "rwnd" to a reasonable value many times the TCP transmission rate is abnormally low, it is likely that the receiving window "rwnd" too small, especially for the network with a large delay, actually receive window " The reasonable value of the rwnd"depends on the size of the BDP, which is the product of bandwidth a
