In the local area network, how to get the MAC address of the PPPoE server is a headache, especially in the Windows environment; There are two ways to get the PPPoE server MAC address:1. Under Windows, we run the Wireshark software, we can get all the packet format and content in and out of the network card, the Wireshark filter is set to PPPoE filter, and then the empty user name password dial, you can see the PPPoE discovery phase of 4 packets, Speci

maintenance. Similarly, in MINA and Netty, encoding and decoding must be inherited to implement the corresponding Encoder and Decoder, while in Twisted, Protocol is inherited to implement encoding and decoding. Although the implementation methods are different, their functions are the same: 1. Fit the message according to certain rules, such as fixed-length messages, specifying the Body length by line, separator, fixed-length headers, etc;

D. Fix a Tree time limit per test 2 seconds memory limit per test megabytes input standard input output standard OUTPU T A Tree is an undirected connected graph without cycles. Let's consider a rooted undirected tree with n vertices, numbered 1 through N. There is many ways to represent such a tree. One-is-to-create an array with n integers p1, p2, ..., pn, where Pi denotes a parent of vertex I (here, for C

very interesting, it receives the IP of the destination host, first sends a ttl=1 to the destination host (remember what TTL is?). UDP (the next to know what UDP is the packet), and after the first router receives the packet, the TTL is automatically reduced by 1, and the TTL becomes 0, the router discards the packet, and simultaneously produces a time-out ICMP datagram to the host. The host receives this datagram and sends a ttl=2 UDP datagram to th

after migrating a database to a new server through a restore or an attached form: 1. Identification: SELECT Dp.name, dp.sid from sys.database_principals DP left joins sys.server_principals sp on dp.sid = Sp.sid WHERE Sp.sid is NULL and dp.type_desc = ' sql_user ' and dp.principal_id > 4; 2. FIX: ALTER USER Fred with LOGIN =

host (Do you still remember what TTL is ?) After the first router receives the packet, the TTL is automatically reduced by 1 and the TTL is changed to 0, the router discards the packet and generates an ICMP datagram that is inaccessible to the host. After receiving the datagram, the host sends a UDP datagram with TTL = 2 to the target host, and then stimulates the second router to send an ICMP data report to the host. Until the target host is reached

addresses over Ethernet, their values are 6 and 4, respectively. The operation field indicates four operation types: ARP request (value: 1), ARP response (value: 2), and RARP request (value: 3) and RARP response (value: 4 ). The following four fields are the sender's hardware address (in this example, the ethernet address), the sender's

discard the packet, and at the same time produce a host unreachable ICMP datagram to the host. The host receives this datagram and sends a ttl=2 UDP datagram to the destination host, then stimulates the second router to send ICMP datagrams to the host. This is repeated until the destination host is reached. In this way, traceroute gets all the router IPs. This avoids the problem that the IP header can only record limited routed IP.Someone asked, how
