 Forums >>  Debuggers  >>  Plugins for Windbg

Topic created on: January 14, 2013 21:02 CST by drew77 .

I am fairly new to using Windbg and am looking for plugins to make it easier to use.

I have not been able to get it to work with symbols stored on my hard drive.

Thanks.

windbg doesnt have plugins it has a few public extensions
one of the more well known extension is by SkyWing Aka Ken Johnson is sdbgext

the next is a grep extension by the name of domdbg

code machine has an extensions that expands the pte pfn and virtual address space explanations a bit more

microsoft securtity research has published an extension for
!is_it_exploitable or some thing to that name  (codeplex i think)

assuming you have stored the symbols on say d:\symbols folder

the directory would / should look like this

D:\SYMBOLS\ntdll.pdb\1751003260CA42598C0FB326585000ED2\ntdll.pdb


now open mycomputers->properties -> advanced -> environment variables->system variables->new

and add an entry for _NT_SYMBOL_PATH

it should look like this

SRV*D:\symbols*http://msdl.microsoft.com/download/symbols



C:\>reg query "hklm\system\controlset001\control\Session Manager\Environment" /v
"_NT_SYMBOL_PATH"

! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\system\controlset001\control\Session Manager\Environment
    _NT_SYMBOL_PATH     REG_SZ  SRV*D:\symbols*http://msdl.microsoft.com/downloa
d/symbols


C:\>

open windbg and it should be able to find the symbols

if you have some more problems

you can issue !sym noisy

inside windbg and it will print diagnostics about what and where and how it is searching for symbols and why it thinks it cant find your symbols
