Re: [rdesktop-devel] rdpproxy problem

[Stefan G. <Ste...@an...>]

Hi Tim,

I think I had the same problem once. It only appears when using an MS RDP5 
Client. If you use rdesktop as client everything works fine.

Try to modify the following in rdpproxy.c

< static const unsigned char client_salt_hdr[] =
<        { 0x01, 0x02, 0x00, 0x00, SEC_MODULUS_SIZE + 8, 0x00, 0x00, 0x00 };
> static const unsigned char client_salt_hdr[] =
>       { 0x01, 0x00, 0x00, 0x00, SEC_MODULUS_SIZE + 8, 0x00, 0x00, 0x00 };

or vice versa - I don't remember which one was rdesktop and the win client ...

Hope this helps!

Did you install the keys (privkey.der, ...) as described in the rdpproxy 
README ?
Hint: You have to boot the w2k servers in "debug mode" to be able to run 
lsadump2.exe successfully!

Stefan
