    dig, a DNS query tool for Windows and replacement for nslookup 2008-04-15 15:29 Disclaimer dig (dig for Windows ) (dig is a powerful tool to investigate [digging into] the DNS system) Source of the binary is from ftp.isc.org Manual Page of dig, in the cryptic Unix style, for reference only. (1) Download: Windows 2000 or Windows XP or Windows Vista ( dig version 9.3.2) Create a folder c:\dig Download this dig-files.zip and save it to c:\dig Use winzip or equivalent to extract the files in dig-files.zip to c:\dig Note: If msvcr70.dll already exists in %systemroot%\system32\ , then you can delete c:\dig\msvcr70.dll Note: Included in dig-files.zip is a command line whois, version 4.7.11: The canonical site of the whois source code is http://ftp.debian.org/debian/pool/main/w/whois/ The whois.exe file inside dig-files.zip is compiled using cygwin c++ compiler. (2) Do a file integrity check (why ? Because some virus checkers destroy dll files) Click Start.. Run ... type CMD (a black screen pops up) cd c:\dig sha1 * You should see some SHA1 hashes (in here, SHA1 hash is used as an integrity check, similar to checksums).

  • Streamlining Integrated Infrastructure Implementation “Dig Once” Strategy Development Workshop June 9, 2016
    Streamlining Integrated Infrastructure Implementation “Dig Once” Strategy Development Workshop June 9, 2016 Workshop Report February 2017 Sponsored By: Alliance for the Chesapeake Bay Local Government Advisory Committee (LGAC) Funding: National Fish & Wildlife Foundation (NFWF) Prepared By: Alliance for the Chesapeake Bay Hirschman Water & Environment, LLC 1. Workshop Overview and Focus The focus of this workshop was to explore better ways to integrate green infrastructure (GI) into other infrastructure projects, such as roads, school and park improvements, and other capital projects. The workshop was hosted by the Alliance for the Chesapeake Bay (ACB) in conjunction with the Local Government Advisory Committee to the Chesapeake Executive Council (LGAC), with funding from the National Fish & Wildlife Foundation (NFWF). Mary Gattis, Director of Local Government Programs for ACB, was the lead facilitator for the workshop. The workshop was held on June 9, 2016 at the Eisenhower Hotel in Gettysburg, Pennsylvania. The organizers targeted certain sector representatives for attendance in order to achieve the necessary cross-section of experiences and points of view. Figure 1 shows the breakdown of attendees by type of organization. A total of 58 individuals attended the 1-day workshop, 52 participants and six staff representatives. See Appendix A for a list of workshop participants. Prior to the workshop, the following problem statement and workshop goal Figure 1. Representation of 52 Workshop Attendees were sent to attendees as part of the agenda. This was done in order to maintain a clear focus for the workshop, as the topic of green infrastructure has many facets, each of which could fill the entire agenda for a one-day event.

We reserve the right to assign partial credit, and to deduct points for answers that are needlessly wordy. 1. True/False [40] For each of the following questions, circle T (true) or F (false). T F 1.1 COBOL was designed as a programming language for scientific and engineering applica- tions. FALSE T F 1.2 The procedural programming paradigm treats procedures as first class objects. FALSE T F 1.3 The “Von Neumann” computer architecture is still used as the basis for most computers today. TRUE T F 1.4 One of the advantages of interpreted over compiled languages is that they tend to offer more run time debugging support. TRUE T F 1.5 Any finite language can be defined by a regular expression. TRUE T F 1.6 Attribute grammars can specify languages that can not be specified using a context free grammar. TRUE T F 1.7 A recursive descent parser can not directly use a grammar that has right recursive rules. FALSE T F 1.8 The lexical structure of complex programming languages like Java can not be defined using regular expressions. FALSE T F 1.9 A non-deterministic finite automaton for a regular language is generally easier to write than a deterministic one, but harder to apply to a string to see if it matches.

  • Manipulating Files and Directories
    MANIPULATING FILES AND DIRECTORIES At this point, we are ready for some real work! This chapter will introduce the following commands: z cp—Copy files and directories. z mv—Move/rename files and directories. z mkdir—Create directories. z rm—Remove files and directories. z ln—Create hard and symbolic links. These five commands are among the most frequently used Linux com- mands. They are used for manipulating both files and directories. Now, to be frank, some of the tasks performed by these commands are more easily done with a graphical file manager. With a file manager, we can drag and drop a file from one directory to another, cut and paste files, delete files, and so on. So why use these old command-line programs? www.it-ebooks.info The answer is power and flexibility. While it is easy to perform simple file manipulations with a graphical file manager, complicated tasks can be easier with the command-line programs. For example, how could we copy all the HTML files from one directory to another—but only those that do not exist in the destination directory or are newer than the versions in the destination directory? Pretty hard with a file manager. Pretty easy with the command line: cp -u *.html destination Wildcards Before we begin using our commands, we need to talk about the shell fea- ture that makes these commands so powerful. Because the shell uses file- names so much, it provides special characters to help you rapidly specify groups of filenames. These special characters are called wildcards.

  • Command-Line IP Utilities This Document Lists Windows Command-Line Utilities That You Can Use to Obtain TCP/IP Configuration Information and Test IP Connectivity
    Guide to TCP/IP: IPv6 and IPv4, 5th Edition, ISBN 978-13059-4695-8 Command-Line IP Utilities This document lists Windows command-line utilities that you can use to obtain TCP/IP configuration information and test IP connectivity. Command parameters and uses are listed for the following utilities in Tables 1 through 9: ■ Arp ■ Ipconfig ■ Netsh ■ Netstat ■ Pathping ■ Ping ■ Route ■ Tracert ARP The Arp utility reads and manipulates local ARP tables (data link address-to-IP address tables). Syntax arp -s inet_addr eth_addr [if_addr] arp -d inet_addr [if_addr] arp -a [inet_address] [-N if_addr] [-v] Table 1 ARP command parameters and uses Parameter Description -a or -g Displays current entries in the ARP cache. If inet_addr is specified, the IP and data link address of the specified computer appear. If more than one network interface uses ARP, entries for each ARP table appear. inet_addr Specifies an Internet address. -N if_addr Displays the ARP entries for the network interface specified by if_addr. -v Displays the ARP entries in verbose mode. -d Deletes the host specified by inet_addr. -s Adds the host and associates the Internet address inet_addr with the data link address eth_addr. The physical address is given as six hexadecimal bytes separated by hyphens. The entry is permanent. eth_addr Specifies physical address. if_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used. Pyles, Carrell, and Tittel 1 Guide to TCP/IP: IPv6 and IPv4, 5th Edition, ISBN 978-13059-4695-8 IPCONFIG The Ipconfig utility displays and modifies IP address configuration information.
