The bootable ISO (~200 Meg) on the website should create, afer a few questions, a server that runs DHCP,TFTP,DNS,dialup,SMTP, LDAP for authentication, nfs-mountable (read-only) thin client root filesystem, and nfs-mountable (read-write) home directory area. I also run wwwoffle, an offline web cache. It has not had a lot of testing, and is quite wizzy-specific sometimes. It also runs UUCP, for use with our system, via dialup or portable USB memory stick for transmission. This provides mail, and offline web browsing, via an administrator-controlled web request interface, for the URL, depth, and other-site URL options. Thin clients either boot from ROM on the network card, or I have a hard disk install option that peacefully co-exists with a Windows lab. It also runs a small local apache server to access webmail and administration. It (deliberately) does not run X. Unmodified, it can serve a Windows network. Your [xgk]dm display manager, and applications server, or few, run elsewhere. This includes your font-server, distributed around the servers if necessary. Also a good candidate are "computer club" servers - running linux-from-scratch :-) Be sure they accept network XDMCP requests. What I do - nfs-mount all home dirs on the wizzy box. Disks can get busy - use SCSI if necessary. Run mail from there also. Now the LTSP servers are generic. Change the ltsp boot scripts to do "X -indirect" instead of "X -query". My post-install scripts make these changes. The server is flagged with its load - choose the less-busy server. Or - only certain servers run office software, games on another, another has only a browser. Teachers could have their own server. Now students can choose at login time - the games machine. Use social engineering instead of software engineering .. I am busy coming up with an LTSP server boot-and-install disk that makes a companion to the wizzy boot server.
