1. mTAIL
TAIL command is well known at the UNIX users. It shows the real-time changes of a text file. Very usefull for log watching operations. A similar to TAIL command wasn’t available for Windows users till now. Here comes mTAIL,a freeware Windows program that emulates the TAIL Unix command.
2. Putty
PuTTY is a free SSH, Telnet and Rlogin client for Windows system.
SSH, Telnet and Rlogin are three ways of doing the same thing: logging in to a multi-user computer from another computer, over a network.
Using public keys for SSH authentication:
Public key authentication is an alternative means of identifying yourself to a login server, instead of typing a password. It is more secure and more flexible, but more difficult to set up.
You generate a key pair, consisting of a public key (which everybody is allowed to know) and a private key (which you keep secret and do not give to anybody). The private key is able to generate signatures. A signature created using your private key cannot be forged by anybody who does not have that key; but anybody who has your public key can verify that a particular signature is genuine.
So you generate a key pair on your own computer, and you copy the public key to the server. Then, when the server asks you to prove who you are, PuTTY can generate a signature using your private key. The server can verify that signature (since it has your public key) and allow you to log in. Now if the server is hacked or spoofed, the attacker does not gain your private key or password; they only gain one signature. And signatures cannot be re-used, so they have gained nothing.
PuTTYgen is a key generator. It generates pairs of public and private keys to be used with PuTTY, PSCP, and Plink, as well as the PuTTY authentication agent, Pageant. PuTTYgen generates RSA and DSA keys.
3. WinSCP
WinSCP (Windows Secure CoPy) is a free and open source SFTP and FTP client for Microsoft Windows. Its main function is secure file transfer between a local and a remote computer. Beyond this, WinSCP offers basic file manager and file synchronization functionality. For secure transfers, it uses Secure Shell (SSH) and supports the SCP protocol in addition to SFTP.
4. nmap
Nmap (Network Mapper) is a security scanner used to discover hosts and services on a computer network, thus creating a "map" of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes the responses. Unlike many simple port scanners that just send packets at some predefined constant rate, nmap accounts for the network conditions (latency fluctuations, network congestion, the target interference with the scan) during the run.Linux is the most popular nmap platform with Windows following it closely.
5. SQuirrel SQL Client
The SQuirreL SQL Client is a database administration tool. It uses JDBC to allow users to explore and interact with databases via a JDBC driver. It provides an editor that offers code completion and syntax highlighting for standard SQL. It also provides a plugin architecture that allows plugin writers to modify much of the application's behavior to provide database-specific functionality or features that are database-independent. It should run on any platform that has a JVM.
6. Tortoise SVN
TortoiseSVN is a really easy to use Revision control / version control / source control software for Windows. It is based on Subversion.
Since it's not an integration for a specific IDE like Visual Studio, Eclipse or others, you can use it with whatever development tools you like.
7. JXPlorer
JXplorer is an open source ldap browser.
