2015: A Cloud Security Wake Up Call
2015 was no stranger to security breaches, so we have to wonder: What needs to change?
Elliott Management Was a Disruptive Force in 2015
Citrix, Riverbed, Juniper, and EMC were on the receiving end of the hedge fund’s meddling ways.
Python script to generate RADIUS users
Just for future reference, I wrote this quick script using python to generate RADIUS users in the Freeradius /etc/raddb/users file. Makes light work of what I used to do rather painfully in Excel:
__author__ = 'amulheirn'
# Create lots of radius users for /etc/raddb/users file
interface = 'ge-0/2/0' # Local source interface
ipaddr = '89.20.80.' # First three octets of IP addr
startuser = 1 # Start of the user range
enduser = 20 # End of the user
for i in range (startuser, enduser):
print 'user%[email protected] Cleartext-Password := "password"' % (i)
print ' Service-Type := "Framed-User",'
print ' Framed-Protocol := "PPP",'
print ' Framed-IP-Address := "%s%d",' % (ipaddr, i)
print ' Context-Name := "tuk_llu",'
print "======[END]====="

How does Internet work - We know what is networking
Routing table will then leave to the switching process the job of load-sharing. That is, route-cache mechanisms like CEF on Cisco device will do load-share per session using source-destination IP.
What’s in a Name?
What’s the difference between .local and .here? Or between .onion and .apple? All four of these labels are capable of being represented in the Internet’s Domain Name System as a generic Top Level Domains (gTLDs), but only two of these are in fact delegated names while the other two cannot be delegated. It seems that Internet no longer has a single coherent name space, but has developed a number of silent and unsignalled fracture lines, and instead of being administered by a single administrative body there are a number of folk who appear to want to have a hand on the tiller! How have we managed to get ourselves into this somewhat uncomfortable position?Process images for your blog with ImageMagick
When writing a blog post about a technical topic, I often capture a lot of screen shots that I need to edit before adding them to my blog article. Usually I want to add a border around each image and I sometimes want to reduce the size of images that are too large. I want to do this quickly and easily so I use ImageMagick, an open-source command line image editor.
It takes too long to edit a large number of images one by one in an image editor like Photoshop or Gimp. Using ImageMagick makes it easy to batch process all images in a folder by entering a simple command. You may also incorporate ImageMagick into shell scripts, batch files, or other programs to automate the preparation of images for your blog.
ImageMagick is a powerful image manipulation tool with an intimidating set of options and subcommands. However, most bloggers will use only a few simple options. In this post, I will show how to install and use ImageMagick to perform the simple image conversions bloggers typically need. I will show how this can be done on each of the major operating systems: Linux, Windows, and Mac OS X.
