Login to D-Link switch

D-Link switch by default (or on reboot/ reset) has following credentials. Following has been verified on model DGS 1210-10P:-

1) IP Address = 10.90.90.90/8
2) Username = admin
3) Password = admin

Pressing the reset pin on switch after disconnecting from router resets it's IP to default value. This takes about 3 minutes. Connect the switch to laptop using ethernet cable. Inorder to connect and login to the switch you need to set the laptops IP within network range of switch. Set static IP on wired network for laptop to 10.90.90.10/8. 
(In ubuntu go to Network > Wired > IPv4.
Select Manual option and add following
Address = 10.90.90.10
Netmask = 8
Click Apply. )

Now go to browser. Type 10.90.90.90 at url field. Prompt to login for switch appears.

Else open terminal in ubuntu. Type
$ sudo telnet 10.90.90.90
Prompt to login with username and password appears.

Settings can be now customised refering to the switch manual.

How to set static IP address for Raspberry pi in headless setup?

Image
For a headless raspberry pi device, which was configured for dhcp service in the network, if the router has become unavailable, the device IP assignment is not done in the network. In such scenario, the device will not be accessible in the network as no IP address is available to it.  Using ssh, the raspberry pi device can be accessed from remote system. This require IP address of the raspberry pi device to be know beforehand. For raspberry pi running Raspbian OS from an SD card, there is a way to directly configure the IP address as static. 1) Remove the SD card and load it into an SD card reader. Now plug the card reader to laptop or reader slot attached with the system. Now two partitions will be mounted on the system /boot and /rootfs. To enable ssh simply create an empty file named ssh in the /boot partition  $ cd /boot  $ touch ssh 2) Navigate to "etc" folder in rootfs partition. In ubuntu terminal  $ cd /rootfs/etc 3) Edit the file dhcpcd.conf

Send and Capture icmp packets with type&code using hping

Here TCL script files are run at terminals of different hosts setup in a mininet environment. The code at one host generates packets of different ICMP types and codes (Please refer to different types and codes associated with ICMP packets at https://www.iana.org/assignments/icmp-parameters/icmp-parameters.xhtml ). The code run at the second host captures these packets and extract the type and code fields. Here hping3, TCL and mininet are installed on Ubuntu system for the experiment. I)    SCRIPTS Script for creating mininet hosts ~~~~~~~~~~~~~~~~~~~~ Save the following in net.py from mininet.topo import Topo class MyTopo( Topo ):     def __init__( self ):         Topo.__init__( self )         # Add hosts and switches         left_host = self.addHost( 'h0' )         right_host = self.addHost( 'h1' )         centre_switch = self.addSwitch( 's0' )         # Add links         self.addLink( left_host, centre_switch )         self.addLink( right_
