Description ----------- Net::Syslog implements the intra-host syslog forwarding protocol. It is not intended to replace the Sys::Syslog or Unix::Syslog modules, but instead to provide a method of using syslog when a local syslogd is unavailable or when you don't want to write syslog messages to the local syslog.

The Net::XWhois class provides a generic client framework for doing Whois queries and parsing server response. One of the more important features of this module is to enable the design of consistent and predictable interfaces to incompatible whois response formats. The Whois RFC (954) does not define a template for presenting server data; consequently there is a large variation in layout styles as well as content served across servers.

Net::TCLink is a thin client library to allow your e-commerce servers to connect to the TrustCommerce payment gateway easily and consistently. The protocol (which is the same across all platforms and languages) is well-documented in the Web Developer's Guide, so please consult it for any questions you may have about the protocol syntax itself.

net-http-persistent manages persistent connections using Net::HTTP plus a speed fix for Ruby 1.8. It's thread-safe too! Using persistent HTTP connections can dramatically increase the speed of HTTP. Creating a new HTTP connection for every request involves an extra TCP round-trip and causes TCP congestion avoidance negotiation to start over. Net::HTTP supports persistent connections with some API methods but does not handle reconnection gracefully. Net::HTTP::Persistent supports reconnection and retry according to RFC 2616.

Description ----------- Net::Telnet allows you to make client connections to a TCP port and do network I/O, especially with a port using the TELNET protocol. Simple I/O methods such as print, get, and getline are provided. More sophisticated interactive features are provided because connecting to a TELNET port ultimately means communicating with a program designed for human interaction. Some interactive features include the ability to specify a timeout and to wait for patterns to appear in the input stream, such as the prompt from a command interpreter.

Net::SSH2 is a perl interface to the libssh2 (http://www.libssh2.org) library. It supports the SSH2 protocol (there is no support for SSH1) with all of the key exchanges, ciphers, and compression of libssh2. Unless otherwise indicated, methods return a true value on success and false on failure; use the error method to get extended error information. The typical order is to create the SSH2 object, set up the connection methods you want to use, call connect, authenticate with one of the auth methods, then create channels on the connection to perform commands.

This is a simple but fast pure Perl module for determining whether a given IP address is in a given set of IP subnets. It's iterative, and it doesn't use any fancy tries, but because it uses simple bitwise operations on strings it's still very fast. All documented functions are exported by default. Subnets have to be given in "address/mask" or "address/length" (CIDR) format. The Socket and Socket6 modules are used to normalise addresses, which means that any of the address formats supported by inet_aton and inet_pton can be used with Net::Subnet.

Virtual Network Computing (VNC) is a desktop sharing system which uses the RFB (Remote FrameBuffer) protocol to remotely control another computer. This module acts as a VNC client and communicates to a VNC server using the RFB protocol, allowing you to capture the screen of the remote computer. This module dies upon connection errors (with a timeout of 15 seconds) and protocol errors. This implementation is based largely on the RFB Protocol Specification, http://www.realvnc.com/docs/rfbproto.pdf. That document has an error in the DES encryption description, which is clarified via http://www.vidarholen.net/contents/junk/vnc.html.

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.
