An easy to do samba scanner

If you had read the post I made some months ago called "Checking the network with bash" and you liked it, you'll probably like this new one. ;)

I used that same script I wrote to find public samba shared resources, data particulary. Windows by default leave some "open resources" that normally you can access mounting it or with some samba tools. So, the thing is: How do I find public resources in a network? This is what I did:

#!/usr/bin/env bash

function scan(){
   SUBNET=${1}
   LAST=${2}
   PING="$(which ping) -c 1 -W 1"
   ${PING} ${SUBNET}.${LAST} > /dev/null 2>&1
   if [ $? -eq 0 ]; then
       SMBRESOURCES=$(smbclient -N -L ${SUBNET}.${LAST} 2>/dev/null |            grep Disk | grep -v \\$)
       if [ ! -z "${SMBRESOURCES}" ]; then
           tput setaf 2
           echo -e "Public samba resources in ${SUBNET}.${LAST}:"
           tput setaf 1
           echo "${SMBRESOURCES}"
           echo -e "------------------------------------------------------\n"
           tput sgr0
       else
           tput setaf 3
           echo "${SUBNET}.${LAST} is up, but doesn't have public resources"
           echo -e "------------------------------------------------------\n"
           tput sgr0
       fi
   fi
}

if [ -z ${2} ]; then
  for((x=1;x<255;x++)); do
      ${0} ${1} ${x} &
  done
else
  scan ${1} ${2}
fi

#EOF

Again, and like always... I hope some find it useful
