Angry IP Scanner – Fast Network Scanner

Angry IP scanner is a very easy to use, fast network scanner – basically a cross-platform IP address and port scanner. It can scan IP addresses in any range as well as any their ports, it’s also very lightweight and doesn’t require any installation, it can be freely copied and used anywhere.

 

Angry IP scanner simply pings each IP address to check if it’s alive, then optionally it is resolving its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be extended with plugins.

How it Works

Angry IP Scanner implements several different methods of detecting alive hosts (pinging).

As a rule, if hosts don’t respond to pings, they are considered dead and therefore not scanned further. This behaviour can be changed in the Preferences dialogue -> Scanning tab. In the same place, you can also select the pinging method:

  • ICMP Echo pinging – This is the same method used by the ping program.
  • ICMP.DLL pinging – This is Windows-only pinging method to compensate for the absence of Raw Sockets.
  • UDP packet pinging – This pinging method is preferred when you don’t have administrative privileges.
  • TCP port probe – This method tries to connect to some TCP port that is unlikely to be filtered (e.g. 80).

Critical OpenSSL security exploit (aka Heartbleed)

Important: Critical OpenSSL security exploit

A serious vulnerability has been discovered in OpenSSL (the most popular SSL module used on Linux based servers). This exploit allows a third party to steal information that would otherwise be secured and encrypted with the SSL/TLS protocol.

If you have a virtual server (VPS) or dedicated server you urgently need to apply the latest OpenSSL patches. Instructions below –

cPanel/WHM:

  1. Login to WebHostManager
  2. Go to cPanel in the left hand menu
  3. Click Upgrade to Latest Version
  4. Follow upgrade instructions
  5. Go to Software in the left hand menu
  6. Click Update System Software
  7. Follow upgrade instructions

SW-Soft Plesk

  1. Login to the Plesk Control Panel
  2. Go to to Settings
  3. Run the Plesk Updater

For the CentOS operating system:

  1. SSH in as root
  2. Run the command ‘yum update’ from the command line
  3. Yum will update the at-risk packages

For Ubuntu or Debian operating system:

  1. SSH in as root
  2. Run the command ‘apt-get update && apt-get upgrade’

If you need assistance patching your systems consider contacting a technical services company such as Aorta Consulting.

Mining Pool Recommendation

Not a lot of time to post at the moment due to a busy work schedule and several life changes.

I do want to take a quick moment and give a shout-out to Jason Hughes (aka wizkid057) over at Eligius. Eligius, maintained by wizkid057, is a 0% fee Bitcoin mining pool which is completely anonymous and provides solid, reliable infrastructure to support the pool user base. Wizkid057 is quick to support pool users via the BitcoinTalk forums.

If you are looking for a primary pool or a secondary pool for your mining rig/s, check out Eligius!

 

SFTP Server for Windows Server 2008 / Windows Server 2012

Those managing and supporting Windows based web servers from the Linux world will be familiar with using Secure FTP (SFTP) which provides file transfer support over an SSH tunnel, generally using port 22. Windows Server 2008 R2 and Windows Server 2012 lack support for Secure FTP (SFTP) and only natively support FTP over SSL which is cumbersome to setup and lacks granular permission and log management.

A number of third party open source and commercial Secure FTP solutions are available for Windows servers including CYGWIN, FileZilla, FTP Shell and IPSwitch.

The fastest and easiest solution to setup is Core FTP Server which  supports SSL/TLS (FTPS), SFTP (SSH2), HTTPS, and clear FTP modes. Core FTP can be setup in a matter of minutes and provides full SFTP support including public/private key authentication.
