To enable 32-bit color depths a earlyCapabilityFlag in the CS_CORE
packet is required. When 32-bit color depth is requested, this
RNS_UD_CS_WANT_32BPP_SESSION flag will now be set. We also advertise
support for 32-bit color depths through the RNS_UD_32BPP_SUPPORT flag.
rdesktop is an open source client for Microsoft's RDP protocol. It is
known to work with Windows versions ranging from NT 4 Terminal Server
to Windows 2012r2 RDS. rdesktop currently has implemented the RDP version 4
and 5 protocols.
Installation
rdesktop uses a GNU-style build procedure. Typically all that is necessary
to install rdesktop is the following:
% ./configure
% make
% make install
The default is to install under /usr/local. This can be changed by adding
--prefix=<directory> to the configure line.
The smart-card support module uses PCSC-lite. You should use PCSC-lite 1.2.9 or
later. To enable smart-card support in the rdesktop add --enable-smartcard to
the configure line.
Note for users building from source
If you have retreived a snapshot of the rdesktop source, you will first
need to run ./bootstrap in order to generate the build infrastructure.
This is not necessary for release versions of rdesktop.
Usage
Connect to an RDP server with:
% rdesktop server
where server is the name of the Terminal Services machine. (If you receive
"Connection refused", this probably means that the server does not have
Terminal Services enabled, or there is a firewall blocking access.)
You can also specify a number of options on the command line. These are listed
in the rdesktop manual page (run "man rdesktop").
