While preparing for some Juniper exams, I wanted to test RADIUS authentication for Junos device access. This way of authenticating is helpful in larger networks. Instead of providing all the devices with several usernames and passwords you can use a centralized RADIUS server for authenticating on all those devices. If that RADIUS server uses the Active Directory as a user database you can login on your network devices using your regular username and password.
The RADIUS server of choice (at the moment of writing this) is Cisco Identity Service Engine (ISE). Overkill for this specific blog post, but fun to do.
Usually, I export my photos from Adobe Lightroom for print or for online display. The exports for online use (SmugMug, Flickr, or several online forums contain a watermark in the bottom right corner. Something that can be done by using the export module in Adobe Lightroom.
I wrote an article a while back on how to do this using Photoshop actions, but this time I want to use a different approach. One without (or at least minimizing) the use of Adobe Photoshop, and using the power of Adobe Lightroom (plugins).
Network Access Control (NAC) is hot in Enterprise environments. NAC offers an excellent mechanism to (safely) allow various devices network connectivity and staying in control as a network administrator. There are numerous ways to allow iOS devices, BYOD, CYOD, Corporate laptops onto your network without compromising valuable corporate resources.
In my line of work I deal with several vendors / solutions to create these NAC protected environments. The most popular at the moment are;
- Identity Service Engine (ISE) from Cisco
- Junos Pulse Access Control (UAC) Service from Juniper
Both solutions have their pro's and cons. Juniper has an excellent client for the desktop to safely connect to the network, and an integration with their SRX firewalls to (dynamically) enforce firewall policies on a per user basis. Cisco on the other hand has a more flexible way of creating access policies, and the use of so-called downloadable Access Lists (dACL).
is not as easy (of funny) as it might sound.
Last weekend we a dinner celebrating the 12.5 years of marriage of my sister-in-law. Our gift was a gazillion envelops filled with;
- useless paper
- 10 euro bill
- .....
This way they had something to do when they came home from the dinner. The fourth option was supposed to be funny money; scanned and severely altered euro billet.
The initial idea was to create a euro bill for 12.5 euro's, but that would take too much work, so I opted for a 55 euro bill (just clone the existing 5 on the 5 euro bill).
