Network commands

Do I start with Dos commands? Ok Yeah!
Click Start>Run and type command then click OK.
Then use the following commands (If you like)
ipconfig -all This displays all the information about you Network card {<Do not expect to display information like > your card is dusty. :) }
Information like The physical address (MAC Address) IP Address and more.
-all is a switch to use switches we use the hyphen- or the slash/
ping [computername/ipaddress] -t Use this command to see if a host is reachable in a network.(communicating with the other)
E.g the other comp is called WORKSTATION2 with IP 192.168.0.2 we can use this command ping workstation2 -t or ping 192.168.0.2 -t Using the t switch it will ping continously untill you cancel.
Without the t switch it will ping 4 times
After the ping is complete You will get a summary showing you the number of packets sent/received/lost and Approximate round trip times in milli-seconds
The more the milliseconds the less the data transfer rate between your computer and the host.
By the way Do you want to ping yourself. Use this IP Address 127.0.0.1 or this computer name LOCALHOST
Tracert > The traceroute utility is an internet coonectivity Utility may like ping but here, if I tracert www.google.com it will display all the router between my computer client and the host (google)
NET command
This command is sweet.
NET SEND [computer name] [message] > This will send a message to the computer name you specify
Example. net send workstation2 Come quick. > That will show a message (come quick) on the computer named workstation2 *** Cool Huh***
Do you want to change your user password or for another user account in your computer without entering the old password? (Hack)
NET USER [USER NAME] [NEW PASSWORD] May be I want to change the password of My boss/Administrator to "cow"
NB: Here you need an administrator account capabilities.
I will type> net user boss cow the user name of my boss is boss
NB: All DOS Commands are followed by an enter/return
Lets now Shut down the computer using a command
Shutdown -f -s -t 7200
The above command will:
-f force all running programs to close without warning
-s and Shut Down
-t After 7200 Seconds equavalent to two hours
OK LETS LEAVE DOS
How do you access a computer's documents in a network? Do you go to my network places> view workgroup computers?
C'mon, thats not for smart pple, go to Start>Run type \\computername and click ok, simple!
May be next am looking at some hardware stuff
For now Bye, If my Content is helping you, Please show your interest through sageauk at yahoo dot com

CREATING A CROSS-OVER CABLE

CREATING A CROSS-OVER CABLE
OK, Isaid four pins are used. Take an example of a simple tin phone you
 
created when in primary school. Your mouth-piece (mic) to the earpiece
 
of the other party and vice versa.
Same case applies here.
Only pins 1,2,3, and 6 are used (the orange and green pairs)
So in this case, the blue and the brown pair are plain wasted.
 
Crimp one end like we did in straight through cable (i.e W.Orange,
Orange, W.Green, Green, Blue,W.Blue,Green,W.Brown,Brown)
Since we are using a Direct connection, Like our example phone we will
 
do the transmitter/receiver stuff all by ourselves. So for the other
 
end SWAP the Orange and the green pairs so thatthe other end will be
 
like (i.e W.Green, Green, W.Orange,Blue,W.Blue,Orange,
Green,W.Brown,Brown)
This is where the name cross-over came from.
Q. Why didn't we do this swaping stuff in straight thro' connection.
A. The cross-over function is done by the switch.
 
Next I will show some simple commands that will help in your windows
 
network.
