The other day a coworker of mine was trying to test if he could access an RDP server on our network, we started by pinging it to see if it was live. My computer is a laptop that runs Linux, but we happened to have a Windows XP machine nearby which I was setting up for someone else. So we used that to test if RDP itself worked. It occurred to me that RDP is used pretty often by people on our network, and that it might be handy to be able to access RDP servers from my laptop in case I ever needed to. After a bit of googling I found rdesktop: http://www.rdesktop.org/
I recall finding this once before, but back then I didn’t feel I needed it. In any case, on most Linux distributions, installing a new application is as simple as one command:
apt-get install rdesktop
yum install rdesktop
…or in my case:
emerge rdesktop
Which compiled/installed the package for me. Emerge is a Gentoo Linux utility, not all distributions require compiling, the two other commands I listed before are on Debian/Ubuntu and RedHat/Fedora respectively, and install binary packages as opposed to compiling.
After that, I simply typed “rdesktop n.n.n.n” where “n.n.n.n” is the IP address of the server we were test-connecting to earlier, and it worked fine. Of course I didn’t have the password for that machine.
Today, Koopa gave me an address so I could try it out a bit more extensively, I connected to it, logged in, and began playing around. It seemed to work fairly reliably, I was able to open several applications and check various server logs, I even opened up IE and browsed around just for the sake of testing. The last thing I did, which I considered the ultimate test, was to see if I could copy text from the RDP session and paste it into my local Linux machine. The first time I tried it didn’t work, but I believe this was just because of Linux’s sometimes random clipboard behavior, I tried it later and it worked great.
All in all I have to say that this is a great solution for anyone who works at a primarily Windows company, but wants to run Linux on their desktop. I’m sure many of you already are aware about Samba which will let you use windows file and printer shares. And if you need to access Exchange/AD stuff, there is the Ximiam Evolution email client which is comparable to Outlook in it’s features and compatibility with microsoft protocols.
As a bonus, a bit of googling reveals that there is also an RDP server for Linux which I have to say surprised me, especially given that the protocol was designed specifically for Windows and integrates a bit more deeply with the Windows system than say… VNC. The server is named Xrdp, and it is available here. As the screenshots show, it seems to work pretty well, despite having an ugly login screen. I think that the login screen is likely a result of some strange details in the RDP protocol, my guess is that the screen that is normally presented to windows users via RDP isn’t exactly the same one they see when logging on locally, and even if it is, it’s likely deeply integrated with the RDP protocol, so they probably had no choice but to write one from scratch for Xrdp directly on top of X11, which isn’t a bad thing, it doesn’t affect functionality.
If I ever have some time I might try setting up a Linux server at home that uses Xrdp, and I’ll make a more detailed post about it. For now, I’m signing off. Later everyone, and happy remote-computing. :)
