JDxpc is a reimplementation of dxpc (the Differential X Protocol Compressor) in pure Java. It is an X protocol compressor designed to improve the speed of X applications run over low-bandwidth links (such as dialup PPP connections). JDxpc encrypts the compressed data stream in SSL.
Jetmon is a client/server NOC monitor tool, allowing light-weight applet in any browser to monitor network device reachablity information from a central server. It provides simple red-light/green-light indicators in a tiered display, with optional history and status windows, accumulative stats, and exteral URL links to MRTG-like pages, all from a single interface.
JFwadmin is a Java 2 high-level X11 tool for ipchains. The GUI displays easy-to-understand services. Features include scripts generation, firewall save and restore, automatic interface and IP address and routes detection, current firewall configuration display, and handling of masq-modules and port-forwarding.
IPWatch will reconfigure your machine after an IP change by reinitializing the hostname, restarting the system logging facilities to use the new hostname, restarting your firewall, and updating your dynamic hostname (it supports yi.org, homepc.org, justlinux.com, dhs.org, dyndns.org, and dyndns.com). It will also restart your network if your machine loses connectivity. In both cases, email is sent with a full log of everything that's been done (including your new IP address).
ip_relay can shape the TCP traffic forwarded through it to a specified bandwidth and allow this specified bandwidth to be changed on-the-fly. Multiple data streams to different hosts/ports may be shaped to the same total bandwidth, much like a traffic shaping router would; however, this application runs in user space, and works by acting as a TCP proxy.
IRCtl is a LIRC-compatible driver for the IR remote control in the FlyVideo98 TV card. There is always a newest version of this driver in the Lirc CVS tree. It is a patch against kernel bttv driver plus loadable lirc driver module. The kernel patch also enables support of the FV98 card in the kernel bttv driver.
IrNET is a protocol allowing to carry TCP/IP traffic between two IrDA peers in an efficient fashion. It is a thin layer, passing PPP packets in a IrTTP socket. It uses PPP in synchronous mode for efficiency, and offers lots of flexibility and various features. The main part of IrNET in included in kernel 2.4.x, and a user-space daemon (to automate connections) is available on the web page.
IsinGlass is a firewall setup script designed to protect dial-up users (but also useful for others). It protects your system against security holes in programs the user may not even know they're running. Most users can run it "out of the box" without any configuration required. It will automatically detects network interfaces and IP addresses. Now works with ipchains.
Isinglass is a firewall setup script designed to protect dial-up users. It protects a user's system against security holes in programs user may not even know are running. Most users can run it "out of the box" without any configuration required. It will automatically detect network interfaces and IP addresses. isinglass-hzd is an unofficial bugfix/2.2 support release.
iSSL (independant Secure Sockets Layer) is a minimalistic cryptographical API that uses the RSA and AES ciphers to establish SSL-alike, secure encrypted communications between two peers communicating through a network socket, including session key generation and public key exchange.
