This macro checks if a pointer is valid _after_ we've already used
that pointer. So it will only trigger if we're already performed some
for of buffer overflow. As such, it provides little to no value and
can only server to encourage broken behaviour.
Let's remove it and replace it with proper bounds checking before
access instead.
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 2012 R2 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 retrieved 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).
