Interaction Between Web Browsers and Script Engines

The script engine which executes JavaScript needs to Ångströmlaboratoriet Lägerhyddsvägen 1 interact with web browser to get access to its DOM elements and other host objects. Hus 4, Plan 0 Browser from host side needs to initialize the script engine and dispatch script source code to the engine side.

Lab Exercise – Ipv4
Lab Exercise – IPv4 Objective To learn about the details of IP (Internet Protocol). IP is the network layer protocol used throughout the Internet. We will examine IP version 4, since it is ubiquitously deployed, while the IP version 6 is partly deployed. The trace is here: https://kevincurran.org/com320/labs/wireshark/trace-ipv4.pcap The text file is here: https://kevincurran.org/com320/labs/wireshark/trace-ipv4.txt Requirements Wireshark: This lab uses the Wireshark software tool to capture and examine a packet trace. A packet trace is a record of traffic at a location on the network, as if a snapshot was taken of all the bits that passed across a particular wire. The packet trace records a timestamp for each packet, along with the bits that make up the packet, from the lower-layer headers to the higher-layer contents. Wireshark runs on most operating systems, including Windows, Mac and Linux. It provides a graphical UI that shows the sequence of packets and the meaning of the bits when interpreted as protocol headers and data. It col- or-codes packets by their type, and has various ways to filter and analyze packets to let you investigate the behavior of network protocols. Wireshark is widely used to troubleshoot networks. You can down- load it from www.wireshark.org if it is not already installed on your computer. We highly recommend that you watch the short, 5 minute video “Introduction to Wireshark” that is on the site. wget / curl: This lab uses wget (Linux and Windows) and curl (Mac) to fetch web resources. -

K30503041: Creating a Virtual Server with ARP And/Or ICMP Disabled at Creation
K30503041: Creating a virtual server with ARP and/or ICMP disabled at creation Non-Diagnostic Original Publication Date: Apr 16, 2020 Update Date: Apr 16, 2020 Topic You should consider using this procedure under the following condition: You want to create a new virtual server with the Address Resolution Protocol (ARP) and/or the Internet Control Message Protocol (ICMP) disabled at creation. Description In some network environments, you may want to create virtual servers that have ARP and/or ICMP disabled. When creating a new virtual server (one that does not use an IP address of an existing virtual server), you can enable or disable the virtual server. However, you cannot set the IP address of the virtual server with ARP and/or ICMP to 'disabled' when creating the virtual server. You can only enable or disable ARP or ICMP by modifying the virtual address that is automatically created when you create the virtual server. In this scenario, you create the virtual address with ARP and ICMP enabled at the time of creation. You can work around this scenario by creating the virtual address for the virtual server in advance with ARP and/or ICMP disabled. After creating the virtual address, you can then create the virtual server that references the same IP address of the virtual address as the destination IP address of the virtual server. Prerequisites You must meet the following prerequisite to use this procedure: Administrative access to the BIG-IP Configuration utility or the TMOS Shell (tmsh). Note: You cannot create a virtual address using the Configuration utility. -
