I have a system with two Lan cards
Eth0 is assigned with 10.22.33.21 IP address and default gateway is 10.22.33.1
Eth1 is assigned with 192.168.0.1 IP address and default gateway is 192.168.0.100
Now the system communicate with any system in these networks(10.22.33.0 and 192.168.0.0). The answer is no.
Never try to assign multiple gateways to a system if it have more than one LAN card.
Just assign a single gateway for effective communication.
So in this example we can have two scenarios:
Either you can assign Eth0 10.22.33.21 IP address with default gateway as 10.22.33.1 and Eth1 should have just an IP 192.168.0.1 no default gate for this Eth1 interface
Or
Eth0 10.22.33.21 IP address without default gateway and Eth1 IP address 192.168.0.1 with default gateway as 192.168.0.100.
You may get doubt if I assign multiple default gateways what will happen?
Ans : You cannot communicate/ping properly to other networks. If you want to try this out try on a test network and feel the difference.

In most of the linux machins terminal option will be there on right clicking on desktop. But strangely in Ubuntu there is no such fecility.
For admins/power users who are using linux require terminal/console access with easy. So in this post i will show you how to right click terminal option in ubuntu. Just execute below command you terminal is there on your right click of the mouse.
apt-get install nautilus-open-terminal
Once this installed try to check if you are able to get terminal option on right clicking on desktop, if you didnot get any such option just restart the machine and check. You will get the terminal option.
