Hardened Debian improves Debian GNU/Linux with high security and hardening features, hardened kernels and packages, DHKP, and other security related enhancements. It makes systems more difficult to compromise using common attacks such as race conditions, chroot jail escapes, and buffer overflows.
Nast is a packet sniffer and a LAN analyzer based on Libnet and Libpcap. It can sniff the packets on a network interface in normal mode or in promiscuous mode. It dumps the headers of packets and the payload in ASCII or ASCII-hex format. Various packet filters can be applied. The data sniffed can be saved in a separate file. As an analysis tool, it can check for other NICs on the network which are set in promiscuous mode, build a list of all hosts on a LAN, find a gateway, perform port scanning on a multiple hosts, catch daemon banners, follow the TCP data stream, reset a connection, and determine whether a link type is a hub or switch.
PHP Shell is a shell wrapped in a PHP script. It's a tool you can use to execute arbiritary shell-commands or browse the filesystem on your remote Web server. This replaces, to a degree, a normal telnet-connection. You can use it for administration and maintenance of your Web site using commands like ps, free, du, df, and more.
Telconi Terminal is an unique network management application with interactive full-screen configuration editing, browsing, help facility support, debugging, and more. It focuses on common Cisco IOS functionality present with any hardware or software configuration, and complements the command line interface with a rich set of features. It is intended for users with knowledge of Cisco IOS, and is designed to work with any IOS-based device, such as routers and switches.
Telephone Control Daemon allows a user to dial a system and perform some predefined commands. It uses a voice modem (tested with Rockwell) to provide a DTMF-based interface to the user. It is useful for systems that only have a temporary Internet connection but may need to be connected at the demand of some remote user.
Mail2sh makes it possible to carry out shell commands by email. Email is sent to a particular user on your host and the commands will be carried out if the user and password given matches ones in /etc/passwd. Commands are executed with the user's privileges, and combined with a PGP module ensures a certain level of security for use. Note that the system is not natively encrypted, so use of an encryption mechanism is highly recommended for security reasons.
