Diskless Linux Workstation
We need a server with DHCP and TFTP.
TFTP
In Debian Etch we have at least three DHCP server: tftpd, tftpd-hpa and atftpd. The first one is not suitable because PXELINUX requires that the TFTP server supports the “tsize” TFTP option. The second has a BSD with advertising clause license. So we went with atftpd, which is also the preferred TFTPD at Debian Popularity Contest.
We changed the home directory for TFTPD, choosing /boot/tftp
. See the command line in /etc/inetd.conf
.
