Doing Intro Unix training at a client site. The classroom had PCs with Hummingbird's XDMCP software to remotely connect to a monster HP unix system. On Monday arrival I learned their HP license expired over the weekend and remote access was not possible. I had my laptop, either a Pentium or P II, running Solaris x86. I put it on the network and had the students point their XDMCP to it. Ran the first two days of class with 12 students plux the console all running X graphical logins. On Wednesday they had us switch to the HP. Some students asked if they could switch back because the laptop seemed more responsive. Jon -- Jon H. LaBadie jon at jgcomp.com 11226 South Shore Rd.
