LECTURE TCP-IP PROTOCOL SUITE - CHAPTER 23: SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)

We have already talked about using SSL between the user’s computer and the server. You should also think about the situation where you are transmitting data from one component of your system to another over a network. A typical example arises when your MySQL database resides on a different ma[r]

Testing the Network Layer
• ICMP is the messaging protocol for the TCP/IP suite.
ICMP provides control and error messages and is used by the ping and traceroute utilities. Although ICMP uses the basic support of IP as if it were a higher-level protocol ICMP, it is[r]

27.6 TCPAP Standards For Electronic Mail Service
Recall that the goal of the TCP/IP protocol effort is to provide for interoperability across the widest range of computer systems and networks. To extend the interoperabil- ity of electronic mail, TCP/IP divides its mail stand[r]

Switch: A device used to connect multiple network segments or devices. Switches can perform routing to the correct network segment rather than broadcasting transmissions to the entire network as hubs do.

Recall from Chapter 4, "TCP and UDP," that there is an initial handshake process that must take place between hosts before a TCP conversation can occur. It is during this phase that the attacker would have to guess the initial sequence number sent in reply to the SYN request from[r]

The same thing is happening with voice. Many skeptics do not believe IP can give the proper QoS for such a real-time application, but with the proper network design and the right tools, it is possible.
This chapter also covered different queuing techniques, such as WFQ, CB-WFQ, LLQ[r]

The Ping.exe command-line tool for Windows Server 2008 and Windows Vista is the primary network tool for troubleshooting IP connectivity. The Ping tool tests reachability, name reso- lution, source routing, network latency, and ot[r]

4.6.4 Packet Traffi c
If the MAC is even partially functional, then by far the simplest way of getting frames into and out of the DUT is to use an external traffi c generator and transmit frames to the DUT. For example, most AP MACs will issue beacons and respond to probe requests, provided the[r]

One additional aspect of SNMP MIBs should be discussed, in that this concept is extremely helpful in managing large networks. There is a potential problem with man- aging SNMP devices on a network over the network itself (security is another matter). The problem is simply this:[r]

In order to negotiate and create IPsec SAs, the two IKE processes on both peers must first establish a secure IKE key-management session over which they will negotiate and instantiate IPsec protection policy.Because IKE negotiations must be protected, each IKE negotiation begins by each pe[r]

The easiest way to protect read/write data is to use a single lock for all the data that needs to be protected. This is a simple approach, but results in problems related to serialization. Every thread that attempts to manipulate the data will have to wait in line to acquire the lock. If a[r]

In this chapter, we introduce a wide area network (WAN), SONET, that is used as a transport network to carry loads from other WANs. We first discuss SONET as a protocol, and we then show how SONET networks can be constructed from the standards defined in the protocol.
