Few days ago I put experimental linux app online. It should work on most modern linux distributions. It uses enigma executable compiled with -march=pentium3, (gcc 3.2), so it may not work on older CPUs, I haven't checked that yet. If you want to try it out, please remember, that you have to chmod +x enigma_0.76_i686-pc-linux-gnu manually (it's inside project's dir) after you attach to project. For some reason, BOINC does not do that automatically. EDIT: I think it's fixed now.
