Free port scan utility software for linux

Port Scanner provides a tool to check for open ports.

Port Scanner will try to connect on every port you define for a particular host. If a connection is made, it will try to read any data returned.

This product is intended for individuals to test their own equipment for weak security, and the author will take no responsibility if it is put to any other use.

Amazon sell many books on Security that will enhance your ability to keep your computer secure.

Port forward is a java application which gives you the ability to open tunnels between your local computer and a remote ssh server. With Port forward, tunnels can be created both local or remote.

Examples:

1. Open a local tunnel to reach a remote mysql database

- Your application needs to connect to a remote database server (mysql for example), but the database server (remote.server.example) is not configured to expose mysql to internet directly.
- Port forward will open a local port (3306) and redirect the connections to remote.server.example ssh server
- The remote.server.example ssh server will connect to its local mysql server

2. Open a local tunnel to use a remove VNC desktop

- You want to connect to your home computer which has a vnc server but from work, the firewall blocks vnc connections (generally on port 5901)
- If you have a ssh server at home, you could use it as bridge to connect to a client in your home:

Your position internet your linux ssh server ->>
-->> you client with vnc (192.168.0.40)

you office
internet >

3. Open a remote tunnel to pilot a remote linux server non reachable through internet
In this example, you will create a remote tunnel, this will give the remote man to connect to and reach you.

I used this example if I have to pilot a remote pc, but this pc has no static IP or is behind a firewall
The good solution is to activate port forward on the pc to be piloted and to connect it to a server we can access.


PC 1 (to be piloted) --||||-- firewall ----- internet ----- accessible-server

Installation:

Be sure java is in you classpath
tar zxvf portforward.tar.gz
cd portForward
sh run_linux.sh

Email Administration Utility provides an IMAP-based email account management utility.
The Email Administration Utilities package can be used to manage email accounts with a series of PHP-based scripts through a browser.
Addition, Removal, and modification of accounts is possible as long as an IMAP port is available on the mail server.
The Mailadmin project was originally designed to help owners of domains that were hosted by Hub.Org Networking Services. The company wanted users to be able to create, remove or modify email accounts when ever they wanted, giving them a quicker turnaround for Mail Administration Purposes.
As the utility was developed, tested and matured into what it is today, many users requested more features or contributed reports of issues to help improve the utilities stability. Hub.Org has given me permission to release the utility as an Open Source package so that others may also benifit from the simplicity that the Mailadmin utility offers to those who need complete control over email accounts.
With this in mind, I intend to continue development by adding new features as they are requested and fix any issues that may pop up. The more users who use and test the features that the Mailadmin utility offers will help to improve the functionality offered by Mailadmin. I have opened a Sourceforge account to help manage the development and releases of the utility as it matures into what users and developers see the Mailadmin to be.
Main features:
- Administrator:
- Adding/Deleting Email accounts.
- Setting Account Quotas.
- Obtaining Administrative Access Over Older Accounts.
- Changing An Accounts Password.
- Interfaces with the Cyrus IMAP/POP3 server.
- Transaction Log system, allowing you to track changes or to help debug issues.
- Standard User:
- Changing The Accounts Password.
- In Development:
- Transaction Log system, allowing you to track changes or to help debug issues.
