Gnetworktester is an application that helps users in testing the quality of a network connection and in sending complaints on that to the network provider. A procedure of testing takes three steps: choosing the network nodes; automatic pinging of those nodes to collect statistics on packet losses, delays, and overall quality; and automatic report writing.
Wiremaps is an application that gathers layer 2 wiring information on a network using protocols like LLDP, EDP, CDP, and SONMP. It also gathers information from the FDB (MAC-port table on switches), the ARP table (MAC-IP table), and some miscellaneous information like interface names.
sslsweep tests TCP services for the presence of SSL and reports things about the services found, such as the certificate's CN, the certificate's expiration timestamp, what kinds of ciphers the SSL service supports, and what versions of SSL the service supports. It can be used for security testing as well as ongoing monitoring of services. It can produce output in human readable text, HTML, and CSV. It can also run as a Nagios plugin. It can accept input on the command line or on standard input (one host:port pair per line). It can also accept Nmap scan output (in the greppable format) as input, and it will test all open TCP ports found by the Nmap scan.
By using the nmblookup facility from Samba, and configuring hosts to use the WINS service, IP-ID lets you resolve named hosts within your local network. As an added feature, IP-ID can discover and add a hostname for an Xbox running XBMC, allowing simple and repeatable FTP transactions with the Xbox. By drawing on the functionality provided by the MiniUPnP project program, IP-ID can also configure UPnP port forwarding to machines to allow SSH access from the wider world.
mod_asn is an Apache module that uses BGP routing data to look up the autonomous system (AS) and the network prefix (subnet) which contains a given (client's) IP address. mod_asn is highly scalable. To do lookups in high-speed, it uses the PostgreSQL ip4r datatype, which is indexable with a Patricia Trie algorithm to store network prefixes. This is the most suitable algorithm, being able to search through around 250,000 existing prefixes quickly. mod_asn is usable as a standalone module, and the lookup result can be used by scripts or other Apache modules. For instance, a download redirector could base its decisions on the lookup result provided by mod_asn.
The pylib library features the popular py.test command line tool for rapidly writing and running tests in Python and py.execnet, a new way to do ad-hoc distribution of Python code to remote processes. py.test runs well on Linux, Windows, and OSX using Python 2.4 through to 2.6. It can distribute a single test run to multiple machines. It is used in many projects, ranging from running tens of thousands of tests integrated with buildbot to a few inlined tests on a command line script.
