Using the Cisco IOS Web Browser User Interface
Using the Cisco IOS Web Browser User Interface The Cisco IOS software includes a Web browser user interface (UI) from which you can issue Cisco IOS commands. The Cisco IOS Web browser UI is accessed from the router home page, and can be customized for your business environment. For example, you can view pages in different languages and save them in Flash memory for easy retrieval. For a complete description of the Cisco Web browser UI configuration commands in this chapter, refer to the “Cisco IOS Web Browser User Interface Commands”chapter of the Configuration Fundamentals Command Reference. To locate documentation of other commands that appear in this chapter, use the Cisco IOS Command Reference Master Index or search online. • Finding Feature Information, on page 1 • Prerequisites for Cisco IOS Web Browser User Interface, on page 1 • Restrictions for Cisco IOS Web Browser User Interface, on page 2 • Information About Cisco IOS Web Browser User Interface, on page 2 • How to Configure and Use the Cisco IOS Web Browser User Interface, on page 7 • Configuration Examples for the Cisco IOS Web Browser User Interface, on page 12 Finding Feature Information Your software release may not support all the features documented in this module.

Voice Over IP Digital Phone Concerns with Security and Fire Alarm Communications Systems
Voice Over IP Digital Phone Concerns with Security and Fire Alarm Communications Systems OMNI Fire and Security Systems LP, 9811 North Freeway #A101, Houston, TX, 77037, (281) 591-1944 Disclaimer: The term “digital phone” as used within this document refers to the generic VOIP phone infrastructure and layout. The term does NOT refer to the Digital Phone service offered by Time Warner Cable or Time Warner. The Digital Phone service is a trademark of Time Warner Communications and for more information on their service, please visit http://www.twcdigitalphone.com. This article outlines the new weaknesses concerned with Voice Over IP (VOIP) Digital Phone Service and how it can affect security and fire alarm system communication. VOIP service is much different than classic POTS telephone lines in that it routes all phone traffic through a digital converter, then over the internet. When compared with a POTS line, new concerns are introduced that could affect the stability and dependability of burglar or fire alarm system communication. Plain old telephone service, or POTS, is the service available from analogue telephones prior to the introduction of electronic telephone exchanges into the public switched telephone network. These services had been available almost since the introduction of the telephone system in the late 19th century. VOIP is a very new technology and this list will help reduce the possibilities of failure wherever possible by educating the end user and presenting possible solutions. 1 Power Supply Problem The VOIP modem can come as a stand-alone network device, or a combination broadband modem/router/and VOIP converter. -

Rebooting a Router
Rebooting a Router This chapter describes the basic procedure a router follows when it reboots, how to alter the procedure, and how to use the ROM Monitor. For a complete description of the booting commands mentioned in this chapter, refer to the “Booting Commands” chapter in the Cisco IOS Configuration Fundamentals Command Reference. To locate documentation of other commands that appear in this chapter, use the command reference master index or search online. Rebooting a Router Task List You can perform the tasks related to rebooting discussed in the following sections: • Displaying Booting Information • Rebooting Procedures • Modifying the Configuration Register Boot Field • Setting Environment Variables • Scheduling a Reload of the System Image • Entering ROM Monitor Mode • Manually Loading a System Image from ROM Monitor • Configuring High System Availability on the Cisco 7500 Series Cisco IOS Configuration Fundamentals Configuration Guide FC-207 Rebooting a Router Displaying Booting Information Displaying Booting Information Use the following commands in EXEC mode to display information about system software, system image files, and configuration files: Command Purpose show bootvar Lists the contents of the BOOT environment variable, the name of the configuration file pointed to by the CONFIG_FILE environment variable, and the contents of the BOOTLDR environment variable. more nvram:startup-config Lists the startup configuration information. On all platforms except the Class A Flash file systems, the startup configuration is usually in NVRAM. On Class A Flash file systems, the CONFIG_FILE environment variable points to the startup configuration, defaulting to NVRAM. show version Lists the system software release version, system image name, configuration register setting, and other information. -

TCP/IP Protocol Suite
TCP/IP Protocol Suite Marshal Miller Chris Chase Robert W. Taylor (Director of Information Processing Techniques Office at ARPA 1965-1969) "For each of these three terminals, I had three different sets of user commands. So if I was talking online with someone at S.D.C. and I wanted to talk to someone I knew at Berkeley or M.I.T. about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them. I said, oh, man, it's obvious what to do: If you have these three terminals, there ought to be one terminal that goes anywhere you want to go where you have interactive computing. That idea is the ARPANET." – New York Times Interview: December 20, 1999 Overview • Terminology • History • Technical Details: – TCP – IP – Related Protocols • Physical Media • Social Implications • Economic Impact 3 Terminology • Protocol – A set of rules outlining the format to be used for communication between systems • Domain Name System (DNS) – Converts an Internet domain into an IP address • Router – A computer or software package used in packet switched networks to look at the source and destination addresses, and decide where to send the packets • Uniform Resource Indicators – Uniform Resource Location (URL) • How to find the resource: HTTP, FTP, Telnet – Uniform Resource Names (URN) • What the resource is: Not as common as URL 4 History: Pre-TCP/IP • Networks existed and information could be transferred within • Because of differences in network implementation communication between networks different for each application • Need for unification in protocols connecting networks 5 History: TCP/IP Development • 1968: Plans develop for using Interface Message Processors (IMPs) • Dec. -

First start and login: After booting from CD, the system is reachable with a browser at the http secure: https://192.168.0.75 Accepting the secure connection we are asked user and password to login: Use these: User: admin Password: zeroshell Now we can use web interface to setup our firewall. Preparing a partition disk where to store our configurations: It’s so important to save our changes that Zeroshell lets us save them in a configuration file. It can be stored in a partition on a hard disk. It’s not necessary to farmat any existing partitions, we can save our configuration files in existing partition such as: ext3, reiserfs, ext2 o fat32. For my own preference I prefer to create a new partition ext3. -
