How generous, helping out a school with its computer infrastructure on a voluntary basis. I don't now if you are aware that there exists good Italian documentation on Debian Edu. See https://jenkins.debian.net/userContent/debian-edu-doc/debian-edu-doc-it/ . You could also want to install the debian-edu-doc-it package for that. > > With the principal we decided to configure the network with Debian > Edu so that we can take advantage of all 23 PCs, some of which dated > (unfortunately) > > The network is structured as follows: > > 1) Main server (AMD Ryzen 7, 32 Gb ram, 1 SSD 500 Gb, 2 network > cards, Debian Edu 10 64 bit) > 2) 12 PCs with 64 bit processor (thin clients e workstations) > 3) 11 old PCs wth 32 bit processor (thin clients) > > At the moment all these PCs are connected to a Main server and to a > router (10.0.0.1/255.0.0.0) via a switch in the 10.0.X.X network > > All the PCs are configured to start via the LAN (PXE) and the > selection screen is displayed for all the PCs: > > Boot from local harddrive > > LTSP diskless workstation (1) > LTSP thin client (2) > > For the 12 best performing PCs (64 bit) I can easily select the > option (1) or (2) because the computers start perfectly and work > correctly > > For the less performing 11 (32 bit) if I select the option (1) or (2) > the following error appears: > > PXELINUX 6.04 PXE 20190226 Copyright © 1994-2015 H.

You have to set up support for older (32 bit) computers. See section 17.2.6. of the manual (Add LTSP chroot to support 32-bit-PC clients). It is the same section number in the Italian manual. It's not just a matter of an appropriate kernel but rather a matter of an appropriate image for the 32 bit clients. > > Is the Debian Edu server able to recognize the hardware that needs to > boot (or even manually set it pc by pc) by "sending" the right > kernel? Yes, this is perfectly possible. See for detailed information Section 17.4 of the manual in general, and more specifically section 17.4.1. LTSP client configuration in LDAP (and lts.conf). > > I thank everyone for any help > regards > > Fabrizio Capurro > > -- Kind regards, Frans Spiesschaert
