[Openvas-discuss] OpenVAS and Cygwin

[John Chajecki]

Jan,

I don't know whether this is a general problem of two Cgwin
applications or OpenVAS build method. All I know is that when Cygwin is
loaded (and I don't need to lanuch any Cygwin applications either)
OpenVas won't launch. The reverse is also true. If I open OpenVAS first,
then Cygwin won't run. The error I get in Cygwin (and I have to type it
out because there seems to be no copy and paste in Cygwin - sigh!) is:

"7 [main] ? (3856) C:\cygwin\bin\bash.exe: *** fatal error - system
shared
memory version mismatch detected - 0x75BE0084/0x8A88009C.
This problem is probably due to using incompatible versions of the
Cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version
*should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL."

The Cygwin installation is vanilla so there should be no issues with
multiple versions of DLLs lying around.
If I shut down OpenVAS and start Cygwin, then it starts fine.

I have found that OpenVAS uses the Cygwin1.dll. Its in C:\Program
Files\OpenVAS-Client\bin but its version 0.132 as opposed to verson
0.156 installed in C:\cygwin\bin. Replacing the file in C:\Program
Files\OpenVAS-Client\bin with the one in C:\cygwin\bin seems to fix the
problem.

Is there any way of making OpenVAS use the already installed Cygwin?

I've heard about this type of problem once, quite a long time ago.
IIRC, the Cygwin versions clashed somehow.
Is this a general problem of two cygwin applications on the same
machine
or more a specfic problem of the OpenVAS build method?

In fact the PDF manual should open up if you click the respective menu
item
in the OpenVAS-Client GUI.

Thoughts

Well, currently LyX is only needed for modifying the manual. Just
reading,
a PDF viewer is sufficient.
