OpenSSH                                         A secure way to access remote computers
               Bilgi:                                   Ssh (Secure Shell) is a program for logging into or executing commands on a remote machine. It provides secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. It is intended as a replacement for rlogin, rsh and rcp, and can be used to provide rdist, and rsync with a secure communication channel. OpenSSH is affiliated with the OpenBSD project, though a portable version runs on most UNIX systems. Note that the SSH.Com link above costs money for some uses, while OpenSSH is always free. Windows users may want to try the free PuTTY SSH Client or the nice terminal-based port of OpenSSH that comes with Cygwin. There are dozens of other clients (free or prorietary) available for most platforms

They complement each other well.

LSOF                                                LiSt Open Files
               Bilgi:                                   Lsof is an extremely powerful unix diagnostic tool. Its name stands for LiSt Open Files, and it does just that. It lists information about any files that are open by processes currently running on the system. It is useful for pinpointing which process is using each network socket. FAQ available here. Changes: Supports reporting of TCP flags, socket options, and states. Adds support for OS X 10.3.2, improved POSIX support, added compatability with newer OS's, and fixed some bugs.

Hunt                                                  An advanced packet sniffing and connection intrusion tool for Linux
               Bilgi:                                   Hunt can watch TCP connections, intrude into them, or reset them. Hunt is meant to be used on ethernet, and has active mechanisms to sniff switched connections. Advanced features include selective ARP relaying and connection synchronization after attacks. If you like Hunt, also take a look at Ettercap and Dsniff.

Honeyd                                              Your own personal honeynet
               Bilgi:                                   Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses on a LAN for network simulation. It is possible to ping the virtual machines, or to traceroute them. Any type of service on the virtual machine can be simulated according to a simple configuration file. It is also possible to proxy services to another machine rather than simulating them.

Achilles                                             A Windows web attack proxy
               Bilgi:                                   Achilles is a tool designed for testing the security of web applications. Achilles is a proxy server, which acts as a man-in-the-middle during an HTTP session. A typical HTTP proxy will relay packets to and from a client browser and a web server. Achilles will intercept an HTTP session's data in either direction and give the user the ability to alter the data before transmission. For example, during a normal HTTP SSL connection a typical proxy will relay the session between the server and the client and allow the two end nodes to negotiate SSL. In contrast, when in intercept mode, Achilles will pretend to be the server and negotiate two SSL sessions, one with the client browser and another with the web server. As data is transmitted between the two nodes, Achilles decrypts the data and gives the user the ability to alter and/or log the data in clear text before transmission.

Stunnel                                             A general-purpose SSL cryptographic wrapper
               Bilgi:                                   The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. It will negotiate an SSL connection using the OpenSSL or SSLeay libraries.

Paketto Keiretsu                             Extreme TCP/IP
               Bilgi:                                   The Paketto Keiretsu is a collection of tools that use new and unusual strategies for manipulating TCP/IP networks. They tap functionality within existing infrastructure and stretch protocols beyond what they were originally intended for. It includes Scanrand, an unusually fast network service and topology discovery system, Minewt, a user space NAT/MAT router, linkcat, which presents a Ethernet link to stdio, Paratrace, which traces network paths without spawning new connections, and Phentropy, which uses OpenQVIS to render arbitrary amounts of entropy from data sources in three dimensional phase space. Got all that? :).

Fragroute                                          IDS systems' worst nightmare
               Bilgi:                                   Fragroute intercepts, modifies, and rewrites egress traffic, implementing most of the attacks described in the Secure Networks IDS Evasion paper. It features a simple ruleset language to delay, duplicate, drop, fragment, overlap, print, reorder, segment, source-route, or otherwise monkey with all outbound packets destined for a target host, with minimal support for randomized or probabilistic behaviour. This tool was written in good faith to aid in the testing of intrusion detection systems, firewalls, and basic TCP/IP stack behaviour. Like Dsniff, and Libdnet, this excellent tool was written by Dug Song.
