rdesktop: A Remote Desktop Protocol client.
rdesktop is a client for Microsoft Windows NT Terminal Server, Windows 2000 Terminal Services, Windows 2003 Terminal Services/Remote Desktop, Windows XP Remote Desktop, and possibly other Terminal Services products. rdesktop currently implements the RDP version 4 and 5 protocols.
Installation
rdesktop uses a typical GNU-style build procedure:
% ./configure [options]
% make
% make install
where documentation for [options] can be found by running "./configure --help". Usually no options are necessary. The default is to install under /usr/local, this can be changed with --prefix=directory.
Invocation
% rdesktop [options] server
where server is the name of the Terminal Services machine. Note: if you receive "Connection refused", this probably means that the server does not have Terminal Services enabled, or there is a firewall blocking access.
The rdesktop manual page lists the possible options ("man rdesktop").
