SoftPerfect Network Protocol Analyzer – Network sniffer for Windows

SoftPerfect Network Protocol Analyzer is an advanced, professional tool for analyzing, debugging, maintaining and monitoring local networks and Internet connections. It captures the data passing through your dial-up connection or network Ethernet card, analyzes this data and then represents it in an easily readable form. SoftPerfect Network Protocol Analyzer is a useful tool for network administrators, security specialists, network application developers and anyone who needs a comprehensive picture of the traffic passing through their network connection or segment of a local area network. SoftPerfect Network Protocol Analyzer presents the results of its network analysis in a convenient and easily understandable format. It also allows you to defragment and reassemble network packets into streams. The program can easily analyze network traffic based on a number of different Internet protocols as listed below. SoftPerfect Network Protocol Analyzer features full decoding of the followi

LAN Search Pro 8.4.0

LAN Search Pro 8.4.0 description LAN Search Pro 8.4.0 supports a method to find out files on your network . It helps you save your time and money when you need to find some information in your LAN. It features include a very fast multi-threaded search engine, ability to search hidden network resources , restricted access resources and IP sub-networks and much more. Major Features: Search according to the specified criteria, search filters. Ability to search the hidden resources, IP sub-networks, LAN FTP servers. Ability to search the resources with restricted access (the ones you need a login and password to access). Ability to ignore some computers (e.g. slow servers) when performing the search. You can also search for specific servers only. Ability to search specific network folders and much more. Save, load, sort, navigate, and perform any other actions on the search results. Fast multi-threaded search engine Support of large amounts of data the list can now contain up to 2,000,00

LAN Switching Modes

LAN switch types decide how a frame is handled when it’s received on a switch port. Latency– the time it takes for a frame to be sent out an exit port once the switch receives the frame– depends on the chosen switching mode. There are three switching modes: Cut-through (FastForward) When in this mode, the switch only waits for the destination hardware address to be received before it looks up the destination address in the MAC filter table. Cisco sometimes calls this the FastForward method. FragmentFree (modified cut-through) This is the default mode for the Catalyst 1900 switch, and it’s sometimes referred to as modified cut-through. In FragmentFree mode, the switch checks the first 64 bytes of a frame before forwarding it for fragmentation, thus guarding against forwarding runts, which are caused by collisions. Store-and-forward In this mode, the complete data frame is received on the switch’s buffer, a CRC is run, and, if the CRC passes, the switch looks up the destination addres

Using Telnet on Cisco Router

Telnet, part of the TCP/IP protocol suite, is a virtual terminal protocol that allows you to make connections to remote devices, gather information, and run programs. After your routers and switches are configured, you can use the Telnet program to reconfigure and/or check up on your routers and switches without using a console cable. You run the Telnet program by typing telnet from any command prompt (DOS or Cisco). You need to have VTY passwords set on the routers for this to work. Remember, you can’t use CDP to gather information about routers and switches that aren’t directly connected to your device. But you can use the Telnet application to connect to your neighbor devices, and then run CDP on those remote devices to get information on them. You can issue the telnet command from any router prompt like this: RouterA#telnet 172.16.10.2 Trying 172.16.10.2 … Open Password required, but none set [Connection to 172.16.10.2 closed by foreign host] RouterA# As you can see, I didn’t set m

CCNA v4 - E2 - Module 6

I don't sure in question 19, please check it. may be true answer is "The default gateway on host B is not correctly set." You can comment about your thing. (95.1%) 1. Refer to the exhibit. In the network that is shown, the router interfaces are assigned the first address in each subnet. Which IP address would be usable for a host on one of the LANs in this network?   192.168.2.130/25 2. Which of the following problems does VLSM help to alleviate?   the shortage of IP addresses 3. What two advantages does CIDR provide to a network? (Choose two.)   reduced routing table size   reduced routing update traffic 4. Refer to the exhibit. The network administrator wants to minimize the number of entries in Router1’s routing table. What should the administrator implement on the network?   CIDR 5. Which of the following are contained in the routing updates of classless routing protocols? (Choose two.)   32-bit address   subnet mask 6. A router has a summary route to network 192.168

CCNA v4 - E2 - Module 5 (100/100)

1. Refer to the exhibit. All routers in the exhibit are running RIP v1. The network administrator issues the show ip route command on router A. What routes would appear in the routing table output if the network is converged? (Choose two).   R 192.168.2.0/24 [120/1]   R 10.10.1.0/24 [120/2] 2. Refer to the exhibit. The Ethernet interface on Router2 goes down and the administrator notices that the route is still valid in the routing table of Router1. How much longer will it take for Router1 to mark the route invalid by setting the metric to 16?   155 seconds 3. Refer to the exhibit. The network that is shown is running RIPv1. The 192.168.10.0/24 network was recently added and will only contain end users. What command or set of commands should be entered on Router1 to prevent RIPv1 updates from being sent to the end user devices on the new network while still allowing this new network to be advertised to other routers?   Router1(config-router)# passive-interface fastethernet 0/0 4. Which
