I finally ported frend2 and the corresponding code in DtCyber to Linux. The initial target was x86 Fedora Core 4, running under VMware Player. Haven't run it on real hardware yet!
DtCyber and SCOPE/Hustler seem to run much faster on a AMD64 system. I used Visual Studio 2005 Beta 2 and Windows 2003 Server Standard Edition for x64, and got SCOPE/Hustler to do a normal deadstart in 70 seconds of real time on a 2.0 GHz AMD64 notebook computer. I don't think we ever did a normal deadstart in 70 seconds on the original hardware...
As of 2005-02-27, frend2 can accept TCP connections to login to SCOPE/Hustler. Interactive sessions seem to be working pretty well, but the system needs more testing.
