ICMPINFO: icmpinfo is a tool for looking at the ICMP messages received on the running host. The source code comes from an heavily modified BSD ping source. USAGE: icmpinfo o Gives info about weird packets only [mainly icmp_unreachable]. icmpinfo -v o Gives info about all ICMP packets [that includes your own traceroutes...] except pings (icmp_echo_reply). icmpinfo -vv o To see pings too. icmpinfo -vvv o Will add an ascci/hexa dump of the packet. icmpinfo -n o Avoids name queries (faster, lighter). icmpinfo -p o Avoids port number to service name queries (faster, lighter). icmpinfo -s o Also decode the ip_src field which is the address of the interface receiving the packet. This option is not usefull for hosts with a single network interface. icmpinfo -l o Run like a daemon (forks) and output to SYSLOG. (It now checks that you are root for that)

The Enhanced TightVNC Viewer package started as a project to add some patches to the long neglected Unix TightVNC Viewer. However, now the front-end GUI and wrapper scripts features dwarf the Unix TightVNC Viewer patches (see the lists below). It adds a GUI for Windows, Mac OS X, and Unix that automatically starts up STUNNEL SSL tunnel for SSL or SSH connections to x11vnc, and then launches the TightVNC Viewer to use the tunnel. It also enables SSL encrypted VNC connections to any other VNC Server running an SSL tunnel, such as STUNNEL, at their end. It can be used to perform SSH tunnelled connections to any VNC Server as well. The tool has many additional features (see below for a list). The short name for this project is "ssvnc" for SSL/SSH VNC Viewer.

OWAMP is a command line client application and a policy daemon used to determine one way latencies between hosts. It is an implementation of the OWAMP protocol as defined by http://www.rfc-editor.org/rfc/rfc4656.txt. (When referring to the protocol within this document, "OWAMP" will be in italicized. In all other instances, "OWAMP" will be referring to this implementation.) With roundtrip-based measurements, it is hard to isolate the direction in which congestion is experienced. One-way measurements solve this problem and make the direction of congestion immediately apparent. Since traffic can be asymmetric at many sites that are primarily producers or consumers of data, this allows for more informative measurements. One-way measurements allow the user to better isolate the effects of specific parts of a network on the treatment of traffic.

Finding the home country of a client using only the IP address can be difficult. Looking up the domain name associated with that address can provide some help, but many IP address are not reverse mapped to any useful domain, and the most common domain (.com) offers no help when looking for country. This module comes bundled with a database of countries where various IP addresses have been assigned. Although the country of assignment will probably be the country associated with a large ISP rather than the client herself, this is probably good enough for most log analysis applications, and under test has proved to be as accurate as reverse-DNS and WHOIS lookup.

EPP is the Extensible Provisioning Protocol. EPP (defined in RFC 3730) is an application layer client-server protocol for the provisioning and management of objects stored in a shared central repository. Specified in XML, the protocol defines generic object management operations and an extensible framework that maps protocol operations to objects. As of writing, its only well-developed application is the provisioning of Internet domain names, hosts, and related contact details. RFC 3734 defines a TCP based transport model for EPP, and this module implements a client for that model. You can establish and manage EPP connections and send and receive responses over this connection. Net::EPP::Client also provides some time-saving features, such as being able to provide request and response frames as Net::EPP::Frame objects.

Net::Random - get random data from online sources This module gets truly random data from online sources. Or at least, they claim to be truly random. The two sources of randomness above correspond to http://www.fourmilab.ch/cgi-bin/uncgi/Hotbits?nbytes=1024&fmt=hex and http://random.org/cgi-bin/randbyte?nbytes=1024&format=hex. We always get chunks of 1024 bytes at a time, storing it in a pool which is used up as and when needed. The pool is shared between all objects using the same randomness source. When we run out of randomness we go back to the source for more juicy random goodness. The maintainers of both randomness sources claim that their data is *truly* random. A some simple tests show that they are certainly more random than the rand() function on this 'ere machine.

SimpleServer is a Perl module which is intended to make it as simple as possible to develop new Z39.50 servers over any type of database imaginable. All you have to do is implement a function for initialising your database (optional), searching the database, and returning "database records" on request. The module takes care of everything else and automatically starts a server for you, listens to incoming connections, and implements the Z39.50 protocol. It couldn't really be easier. SimpleServer is based on the popular YAZ toolkit which means it is robust, efficient, widely portable, and it interoperates with all known Z39.50 clients. Use SimpleServer together with other Perl modules to provide gateways to relational databases, local file stores, SOAP/RDF-servers, etc. SimpleServer currently supports the Init, Search, Present, Scan and Close services.

This is a standalone version of W. Richard Stevens' "sock" program, based on the code available for the UNIX Network Programming book. Adapted and reworked code for W. Richard Stevens' "sock" utility by Christian Kreibich. From the author: In TCP/IP Illustrated Vol. 1, Richard Stevens used a program called "sock" to demonstrate the many properties of TCP/IP. Unfortunately, the book only speaks about how to use the program but does not point to a site for downloading its sources. While sock is contained in the code package accompanying UNIX Network Programming, this code is also getting dated. The program can be used to generate TCP or UDP packets for testing various network features. It runs as either client or server.
