Very Simple Network Scanner

php-port-scan

phpPortScan It's a little handy port-scanning class written in PHP - it can connect to IP's and then check if the specified port is open or not.

geoipgen

Usage Usage: ./geoipgen [OPTION]... [COUNTRYCODE]... IPv4 network tool for generating geotargeted IP addresses. Features: Random or sorted order, unique or repeating ips, skips broadcast addresses, uses MaxMind GeoLite Country database. Target: COUNTRYCODE One or more country ... [More] codes, delimited by spaces Use 'all' to target all country codes Use -l to see the list -n NUM Exits after NUM IPs Unique or repeating: -u, --unique Return each IP in the countries once only (default) --repeat IPs can repeat with random order Order: -s, --sorted Order is sorted, ascending --random Order is random (default) --less-random Order is random seeming, returns each IP only Provides significant performance gain when used with 'all' countrycodes Other: -h Help This message -l, --list-countries List countries and their country codes -c DIRECTORY Location of GeoIPCountryWhois.csv database Default locations: ./, /home/dc/.geoipgen/, /usr/local/share/ -V, --version Print version information. This version is 0.3 ` Examples: geoipgen nz Each IP in New Zealand in a random order without repeating geoipgen nz au Each IP in New Zealand and Australia in a random order without repeating geoipgen --repeat -n 100 cn hk mn tw mo jp kr kp 100 random IPv4 addresses in Far East Asia. It's faster to produce non-unique IPs with --repeat geoipgen all Produce each IP in the world, once only, in a random order. Defaults to use less-random for lower memory overhead. NotesUses the Max-Mind Free Open Source Geo-Lite Country database (www.maxmind.com). It's slower the first time you generate a set of countries, the countrycode map files are created and saved in #{$OURDIR}. After the first time, the countrycode map is reused. It's faster to use --repeat than to make a Bitfield to store whether each IP has been produced. There is another geoIP database here http://software77.net/cgi-bin/ip-country/geo-ip.pl How to dns resolve a countryThis can aid in testing the accuracy of the Max-Mind location data by finding the presence of ip blocks that are potentially allocated to the wrong country. For example, if hostnames ending in .sk are found in a specific IP range belonging to New Zealand then that indicates the IP range allocation is incorrect. For faster dns resolving, use an asynchronous resolver like adns. Install GNU adns Download and follow instructions from http://www.chiark.greenend.org.uk/~ian/adns/ or sudo apt-get install libadns1-bin Pipe IPs to adnsresfilter and only output resolved IPs ./geoipgen nz | adnsresfilter -w -a | egrep "\[.*\]" Example Output 125-238-151-47.broadband-telecom.global-gateway.net.nz[125.238.151.47] 161-65-114-241.ip.fx.net.nz[161.65.114.241] c0.d0.33.static.xlhost.com[209.51.208.192] 203-114-177-78.dsl.sta.inspire.net.nz[203.114.177.78] ds7a04.cc.waikato.ac.nz[130.217.64.150]CreditsAuthored by Andrew Horton (urbanadventurer) horton.nz at-nospam gmail.com Thanks to Max-Mind for making their Geo-Lite Country database freely available.
