Use firefox browser to do ping and tracert

The title says it all, you can run ping and traceroute in your internet browser. It's can be handy for sys admin to do their troubleshooting without the need to open a terminal/command prompt.

Steps

1. Open up your firefox browser.

2. Bookmark these 2 links and put a “ping” & “tracert” keyword for each.

http://network-tools.com/default.asp?prog=ping&host=%s
http://network-tools.com/default.asp?prog=trace&host=%s

3. To create a keyword for your bookmark,  if you are using firefox, hit <Ctrl> + <B> then search for the 2 URL's that you have added just now. When you found it, right click and choose "Properties" on it and you will see something like this

5. After clicking "Properties", a window will pop up and from there you can see there is a "Keyword" field. So just enter the keyword accordingly.

• "ping" keyword for bookmark http://network-tools.com/default.asp?prog=ping&host=%s


• "tracert" keyword for bookmark http://network-tools.com/default.asp?prog=trace&host=%s

Example:

4. Ok, you are all set. Now try to type "ping www.google.com" or "tracert www.google.com" without the double quote on your browser URL address bar

Example:

5. See, the ping/tracert result is showing in the browser

Quite handy isn't it.

Test Your Website Loading Speed

[ad#ad-2]

If you feel that your website is taking ages to load, you can go to http://tools.pingdom.com/ to find out the total loading time for each objects like css, scripts, images and etc. Base on  that, you can find out which object actually causing the long loading time.

The following is the test result of google.com

The Fastest way to calculate hosts/subnet/broadcast

Yes, you are right. The fastest way is to use an IP subnet calculator. You can find tons of free IP subnet calculators over the Internet, example like http://www.subnet-calculator.com/

But, what if something happened to your PC, where you can't use the software or internet to do the calculation for you. Therefore, you should always have a backup, like every IT staff did. Make yourself a backup and learn how to count without any 3rd party tools.

Actually is not as difficult as you think. Here, I will show you an easy way to do it.

Given a scenario, if provides you the IP address and subnet mask. And ask you to find out what is the number of valid hosts, subnet and broadcast address.

Example:
IP - 192.168.10.34
subnet mask - 255.255.255.224 or CIDR (Classless Inter-Domain Routing) :/27

To find subnet and broadcast address.

1) 256 - 224(subnet mask last octet) = 32

First subnet is 32.
Second subnet is 32 x 2 = 64
Third subnet is 32 x 3 = 96
.
.
.

etc

Since our IP (192.168.10.34) is fall between 32 - 64 subnet, so the subnet address is 192.168.10.32 and the broadcast address is 192.168.10.63.

Find Host range

1) Valid hosts range is 192.168.10.33 - 192.168.10.62
- as 192.168.10.32 is subnet, 192.168.10.63 is broadcast

Find total valid hosts

1) 192.168.10.(62) - 192.168.10.(33) = 29

or

32 - 27(CIDR) = 5

2^y = 2⁵ - 2

= 31 - 2
= 29

All solution only got 1 step. Simple isn't it. Still don't understand? Nevermind, let's do another example.
