Was trying to get a list of systems up on the network. Pingall.sh would not work at all. It was driving me nuts. So I went to another system and it worked.

$ cat pingall.sh
a=""
for i in {1..254}
do
ping 192.168.1.$i -c1 -w1 -v | grep "icmp_seq=1"
done

$ ./pingall.sh
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.623 ms
64 bytes from 192.168.1.32: icmp_seq=1 ttl=64 time=0.113 ms
64 bytes...

Our goal here to see what is live on the network and how possibly vunerable those machines are. Might be interesting to use with a wifi network.

First lets get the live systems at the moment. You will need to change your code depending on your network,

alive.sh

Code:

 #!/bin/bash
rm goodips
is_alive_ping()
{
  ping -c 1 $1 > /dev/null
  [ $? -eq 0 ] && echo $i >> goodips
}

for i in 192.168.1.{1..255}

A 486 laptop running floppy based Pitux linux connected via rs232 to a Pogoplug v2 running Arch linux. Knew I would find a use for that old laptop yet.

Microsoft below the surface.

Microsoft Surface is just another touchpad. Why not get a generic touch pad for a fraction of the cost that will virtually do the same thing.

C conversion.

The main thing we did was to add a substitution for get(ch) and clrscr();

Original code:
#include<stdio.h>
void main()
{
int n,d=0,j,a[9];
clrscr();
printf("Enter the Integer which u want to Convert Decimal to Binary : ");
scanf("%d",&n);
while(n>0)
{
a[d]=n%2;
n=n/2;
