feature for NeDi default Topology Map
Because of our requirements I have changed the Topology-Map, primary the d3.js / json part.
It does work, but I think the implementation in the libmap.php can be better.
It’s not finished yet. I’m open for suggestions and feedbacks.
Additional features like save positions, map zoom, change background and more will be implementend soon. For more information please visit the NeDi-Forum http://forum.nedi.ch/ .
Warn:
The code is in the alpha phase.
This is coded for the NeDi version 1.5 .
Info:
I didn’t touch the original functions in the libmap.php file.
I copied it and created two new functions with my changes.
When you call the Topolgy->D3jsmap it creates a new json map file called “map3js_$username.json” instaed of “map_$username.json”
WriteJsonNew()
MapNew()
Install:
1.
please backup the original file first.
like that \hmtl\inc\libmap.php.backup
2.
copy the two files on your nedi HTML folder.
\html\Topology-D3jsmap.php
\hmtl\inc\libmap.php
3.
edit nedi.conf and put this line on GUI Settings.
module Topology D3jsmap paint net
Options:
1. Filter:
I haven’t change anything here.
2. Main
In the d3js map I have only changed the D3js code for my expected results.
I have focused on the Output from the Devices and Nodes(nodes without interface).
3. Layout
Metric: you can set the Charge of the forcelayout // lal default is 120, 120/4=30
Length: you can change the link distance between devices or nodes // len default default is 50, -3*50=-150
4. Show
If Name: show the linked interface between the two devices
Device IP: show the device IP expected in nedi
Room: show the room from the snmp string
OR
Rack: show the rack from the snmp string
When you select both Room and Rack then it show the complete snmp string
Region.City.Building.Floor.Room.Rack
To better indentifying the devices on the same building or room, they have the same font color.
Mode: show the device contact
Mode: show the device model
Tipp:
Go to print mode and then position your devices to print as PDF… or so.
Default Output with Interface like SVG and PNG output… but you can place your devices vy yourself .

Cisco Introduces Cloud and Internet of Things (IoT) Certification
With the Slogan >>Connect the Unconnected<< begins Cisco to build on the Internet of Everything (IoE) and the Internet of Things (IoT) . To education the peoble on this new material Cisco introduces the new Cloud and Industrial Training and Certification program. Very interesting is that for the CCNA Cloud you don’t need to get the CCNA RS first. So you can save time and money to get the new Cloud certification.

Create Binary Image with Linux
To create an image file on Linux we have various options to do the job. We have commands like dd, truncate, mkfile and others. On most linux systems we have fallocate installed by default. The command fallocate is supported only on certain file systems such ext4, xfs, ocfs2 and btrfs. The best choice to create a large file on a Linux system is the command fallocate. Fallocate only allocates/reserves blocks and marking them as uninitialized without requiring I/O and CPU time. This is much faster than creating a file by filling it with zeros like the command dd does.
To make sure we have sufficient disk space to create an image file, we use the command df.
|
1 |
root@OSMIOM:/var/www# df -h /var |
Output:
|
1 2 3 |
Filesystem Size Used Avail Use% Mounted on /dev/mapper/OSMIOM-var 6.0G 1.3G 4.4G 22% /var root@OSMIOM:/var/www# |
We can see, that we have enough disk space to create some image files. To create an image file we use the command fallocate.
Syntax:
|
1 |
fallocate -d [-o offset] [-l length] filename |
Example to create a 100 Megabyte file:
|
1 |
root@OSMIOM:/var/www# fallocate -l 100M myfile.img |
Example to create a 1 Gigabyte file:
|
1 |
root@OSMIOM:/var/www# fallocate -l 1G myfile.img |
Example to create a 10 Gigabyte file:
|
1 |
root@OSMIOM:/var/www# fallocate -l 10G myfile.img |
Let’s verify our new file.:
|
1 |
root@OSMIOM:/var/www# ls -lh myfile.img |
Output:
|
1 2 |
-rw-r--r-- 1 root www-data 1.0G Mar 22 11:05 myfile.img root@OSMIOM:/var/www# |
LAB – NM-8A/S arrived

Are you Shellshock(ed)?
The Shellshock bash bug is a critical security hole for all Unix, Linux and *nix based systems. Bash(Unix Shell) is a piece of Software released by Brian Fox in 1989 for the GNU Project.
The bug can affect you trough malicious requests sent to web servers or network devices.
A number of Cisco products use an affected version of the Bash shell.
Cisco made an official statement that meraki devices are not affected from the Shellshock and Heartbleed vulnerability. See detailed information at the official cisco website.
Cisco Meraki Shellshock
Cisco Meraki Heartbleed
There is a very simple test to check if you are vulnerable. Run the following lines in your default shell.
|
1 2 |
env x="() { :;} ; echo vulnerable" /bin/sh -c "echo stuff" env x="() { :;} ; echo vulnerable" 'which bash' -c "echo completed" |

Last day for 350-001 CCIE Routing and Switching
Today is the last day to take the legendary 350-001 CCIE Routing and Switching v4.0 written or lab exams. The CCIE Routing and Switching exams will be available tomorrow, 4. June 2014.If you have already passed the CCIE Routing and Switching written v4.0 you have to take the CCIE v5 R&S lab exam.
For me everything is clear, I have to focuses my study to the 400-101 CCIE Routing and Switching v5.0 Exam Topics. To prepare for the exam, I have to read many Cisco Press books (see my booklist) and lot of other stuff. At the moment I’ve started to rereading my CCNP Books. My goals for my lab time is to go through the INE’s and Narbik’s workbooks.
Hello World!
Welcome to my blog. This is my first post. My name is Thiago Perrini and currently I’m working as an Network Specialist at the Zurich Airport.
I’ve been in IT for about 11 years, starting with my apprenticeship as Information Technology at the FHBB/FHNW.
I have earned the CCNA RS, CCNA Voice and the CCNP RS certifications. The next logical step is to go for the CCIE. At the next time I’m gonna share my study time and experiences.
Thanks for visiting my blog.
