Requirements
smbmount, smbclient,nmblookup (samba tools)
nmap (Network Mapper)
grep, sed, dialog

a smb scanner written in shell by me

smbscan.sh

# clean old temp files
#rm -f *.out

and the umount script for this smb scanner

umountall.sh
#!/bin/sh
#get forced
echo "unmounting smb file systems (force)"
umount */*/*
#umount `mount | grep smbfs | awk '{print $3}'`
kill -9 `ps aux | grep mount.cifs | awk '{print $2}'`
