Tool for uploading disk images into Amazon EC2 and creating Amazon Machine Images from them.

This is shelldap, a handy shell-like interface for browsing LDAP servers and editing their content. Among its features: - history - sane autocompletes - credential caching - site-wide and individual config - it's in perl - it's fun to say! shelldap! shelldap! shelldap! For more info, 'perldoc' the script.

Shmux is program for executing the same command on many hosts in parallel. For each target, a child process is spawned by shmux, and a shell on the target obtained one of the supported methods: rsh, ssh, or sh. The output produced by the children is received by shmux and either (optionally) output in turn to the user using an easy to read format, or written to files for later processing making it well suited for use in scripts.

The u6rd is a user-space 6rd (RFC 5569) implementation, which uses tun(4) and the raw socket interface. The u6rd daemon runs on the 6rd border router of a 6rd site that is isolated from the native IPv6 Internet. It does not provide the functionality of 6rd "relay" routers.

UCARP allows a couple of hosts to share common virtual IP addresses in order to provide automatic failover. It is a portable userland implementation of the secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD's alternative to the VRRP).

UDPTunnel by Jonathan Lennox; copyright 1999,2001 by Columbia University. UDPTunnel is a small program which can tunnel UDP packets bi-directionally over a TCP connection. Its primary purpose (and original motivation) is to allow multi-media conferences to traverse a firewall which allows only outgoing TCP connections. Source code for Unix is available from See udptunnel.html for installation and usage instructions. See COPYRIGHT for conditions and terms of redistribution. A current version of udptunnel.html is located at Jonathan Lennox September 6, 2001

Simpleproxy program acts as simple TCP proxy. It listens for local socket, and any connection to this port will be forwarded to another socket at remote host. LICENSE: GPL2 or later

Sippy B2BUA is a RFC3261-compliant Session Initiation Protocol (SIP) Back-to-back user agent (B2BUA) server software. The B2BUA is a SIP call controlling component. Unlike a SIP proxy, which only maintains transaction state, the B2BUA maintains complete call state and participates in all call requests. For this reason it can perform number of functions that are not possible to implement using SIP proxy, such as for example accurate call accounting, pre-paid rating and billing, fail over call routing etc. Unlike PBX-type solutions such as Asterisk for example, the B2BUA doesn't perform any media relaying or processing, therefore it doesn't introduce any additional packet loss, delay or jitter into the media path. Features: o Realtime calls control and call data records (CDRs) generation; o Optional ability to use Sippy RTPproxy for media relaying; o Optional ability to perform Cisco-compatible RADIUS AAA (Authentication, Authorization and Accounting); o RFC3261 compliance; o RFC3326 support; o IPv6 support; o Seamless compatibility with majority of popular SIP software and hardware on the market today; o Robustness and Resilience.

Sipsak is a small command line tool for developers and administrators of Session Initiation Protocol (SIP) applications. It can be used for some simple tests on SIP applications and services.

Skstream is an iostream based C++ socket library. It is ideally suited for use as the underlying transport for Atlas-C++, and has been well tested and debugged. It was first discovered for WorldForge when it was used in UClient and has since been packaged up as its own library for use on other WorldForge projects. The code was originally written by Rafael Guterres Jeffman who is not involved with the project but we have extensively rewritten it, and added new features such as IPv6 support and Unix domain sockets. It now maintained for WorldForge by Al Riddoch and others.
