#210 Rdesktop 1.8.3 when neg_proto = PROTOCOL_SSL > g_client_random is empty = failed auto reconnection

admin of admins — Sun, 28 Jun 2015 03:57:16 -0000

Got what was wrong, had to fill it with zeros 32 bytes long. Just took a look into frerdp and possibly there is some bug, they create it with 16 bytes length (not 32 as I did to make it working because 16bytes failed) filled with zeros when protocol == rdp, not ssl and not nla.
But in my assumption, that is security risk to fill clients random key with zeros, than it is not random.
Pretty sure we should extract exponent and modulus from public key and encrypt own random key. I assume, Microsoft RDP server always uses RSA keys.

Well, will continue the tests...

Rdesktop 1.8.3 when neg_proto = PROTOCOL_SSL > g_client_random is empty = failed auto reconnection

admin of admins — Sat, 27 Jun 2015 22:51:27 -0000

Hello,

this situation is easy to reproduce, let's assume you setup proto = PROTOCOL_SSL only connection without providing pass (also proto = PROTOCOL_HYBRID disabled therefore pass can be typed in the session)
In such case packets are sent via established SSL connection without RDP packet encryption and therefore the g_client_random is not created, and when processing reconnection cookie after reconnection it seems rdssl_hmac_md5 function produces wrong sum and auto reconnection fails.
I assume, same would happen with proto = PROTOCOL_HYBRID, but because on my cygwin I was unable to compile with cssp support, can not say to much here, but expect to 99.9% same behaviour, because password gets emptied after succeed logon and can not be reused for auto reconnection.

Tiny Core rdesktop update to 1.8.3

Pieter Van Dam — Wed, 13 May 2015 14:03:44 -0000

Hay,

I am trying to figure out how I can update rdesktop from 1.7.1 to 1.8.3 due to problems with the pointer not showing onscreen but I have no clue on how to do this.

Kind regards

Time Zone redirection

Jonathan Fernandez — Fri, 01 May 2015 14:39:59 -0000

We currently run Remote Desktop Services (windows 2008 R2 SP1) and we have Linux based thin clients, rdesktop version we have running is 1.8.2 and 1.8.3. When connecting to the an RDS server with time redirection active. on the client side it says "Your current time zone is not recognized. Please select a valid time zone using the link below (see attached file). Client time zone is "America/New York", Server is "(UTC-05:00) Eastern Time (US & Canada)".
Outlook client see TZ as "(UTC-05:00) Bogota, Lima, Quito Rio Branco" which causes the calendar entry an hour off.

Tested this on Fedora 21 and Ubuntu 14.04 with rdesktop 1.8.2 and 1.8.3 with the same result.

#207 rdesktop-1.8.3 - Issues connecting to Windows 2012 R2 w/ NLA

Have you setup Kerberos correctly? rdesktop does not support NTLM CredSSP yet.

SLED 11 Service Pack 3
Compiled rdesktop-1.8.3
Compiled with smart-card and CredSSP support (installed PCSC-lite-devel, libgssglue-devel)

Receiving Output:
ERROR: Failed to open keymap en-us

Let me know if there's any additional information I can provide.

#206 Getting Expected data got 3 error for some Windows 2008 and 2003 servers

one more observation is this issue is not reproducing when we try to connect to the server using "mstsc".

Thanks,

#206 Getting Expected data got 3 error for some Windows 2008 and 2003 servers

Pavan G — Sat, 31 Jan 2015 05:05:31 -0000

Hi Team

I saw and found the code in mcs.c file

Below is piece of code where it gets the error.

if (appid != MCS_SDIN)
{
if (appid != MCS_DPUM)
{
error("expected data, got %d\n", opcode);
}
return NULL;
}

What does the meaning of code and when it will get into this error while taking RDP server console.

What is the opcode value if we get 3

Thanks & Regards,
Pavan G.

Getting Expected data got 3 error for some Windows 2008 and 2003 servers

Pavan G — Fri, 30 Jan 2015 13:59:52 -0000

Hi Team

We have some servers with operating systems of below flavors.

Microsoft Windows 2008 Enterprise edition
Microsoft Windows 2008 Standard edition
Microsoft Windows 2003 servers

When we are trying to get RDP to those servers, getting "Expected data got 3" error. One more main thing here is the specified error is not getting for all the servers of same operating system in above list.

Is this issue exists in the server point of view and code point of view ?

Could you please explain me on this issue and solution with server side configuration and code fix ?

Thanks & Regards,
Pavan G.
