There's no Radmin version for Linux OS. We are planning to develop a Linux version of Remote Administrator, but now we are extremely busy with beta-testing of Radmin 3.0. The development of Linux version was not started yet.
It's possible to run Radmin 2.x Viewer (but not Server) under Transgaming's WineX (Windows emulator for Linux)
1. download this RPM: ftp://ftp.codeweavers.com/pub/cw-wine/codeweavers-wine-20020904-7.i386.rpm
(for mandrake user: remember to do a printerdrake from the terminal before install , go to expert section and install your printer, it will give you the xmessage dependence that codeweavers needs and that you can't found anywhere else)
2. you must be logged in as root for install (rpm -i codeweavers-wine-20020411-6.i386.rpm)
3. Now you must log out from root and type winesetup with normal user account.
4. Run radmin by doing: "wine Radmin.exe"
Remember WineX has a limitations and it can't be launched from as (since WineX setup can't handle root user) so use a normal user to lunch "wine Radmin.exe" command.
The only limitation is that keyboard shortcuts are disabled (for example, F12 can't switch screen modes) and right-click on the top of the screen won't change screen mode.
I want to know that why Radmin do not have web viewer
There's no web interface for Radmin, since it would be great security hole. Releasing web-based user interface would force endless attacks to your Radmin Server from the Web and, most importantly, web traffic encryption is much poorer than internal Radmin encryption, so passwords can be stolen.
That's why you must download Radmin from our site and install it on your computers in order to use Remote Administrator. Anyway, we are constantly thinking about solution, so it may be developed later.
We are planning to develop Mac version of Remote Administrator, but now we are extremely busy with beta-testing of Radmin 3.0. The development of Mac version was not started yet. However, you can try running Radmin Viewer under Virtual PC or other Windows emulator for Mac. Radmin has 30-day trial period, so you won't need to buy it to test is you would be able to run Radmin under Windows emulator for Mac.
