Linux RDP Clients

michael writes "Does anyone know a RDP Client for Linux? RDP clients allow you to access Microsoft terminal servers - quite similar to Citrix ICA. I know there are at least two of them - from Compaq and Igel. However, both seem to be bundled with the hardware (thin clients). I spoke to someone at Igel last year and they said they were still unsure whether they'd sell it seperately (or even give it away for free). I wasn't able to reach somebody at Compaq. Are there any other products like this (free or commercial)? "
