The following is the server's current hosts file (IP addresses masked):

x.x.x.27 sheridan.sbcc.cc.ca.us # Sheridan, the LTSP server
127.0.0.1 localhost
x.x.x.110 ws001 # This is the workstation being tested
x.x.x.8 xsruid # A server the workstation "crashes"
x.x.x.14 spock # Another server that dies at LTSP login
#209.129.49.10 csns # The dedicated DNS, also TFTPd for other terminals


Regarding keeping the terminals in the hosts file: The DNS server doesn't
seem to want to let me do that. This is another odd problem. When I use the
"fixed-address" option, the DHCP server DOES NOT tell the LTSP terminal
about its root directory or what filename to download for its kernel.
(huh!?). The following is the current, working dhcpd.conf for the DNS:

#------------BEGIN--------------
option domain-name "sbcc.cc.ca.us";
option domain-name-servers x.x.x.10;
option routers x.x.x.69;
max-lease-time 86400;
default-lease-time 61200;
shared-network CSLAB-NET {
subnet x.x.x.0 netmask 255.255.255.128 {
range x.x.x.21 x.x.x.60;
range x.x.x.96 x.x.x.126;
}
}

# Added by Charles Burns 13NOV2002 for LTSP terminals
group {
use-host-decl-names on;
host ws001 {
hardware ethernet XX:XX:XX:XX:XX:XX;
next-server x.x.x.27;
filename "/lts/kernel.ltsp";
option root-path "x.x.x.27:/opt/ltsp/i386";
#fixed-address x.x.x.110; ## See below ##
}
}
#---------------END------------

The line: "fixed-address x.x.x.110;", enabled, ultimately makes
the LTSP system think that it is looking for "/tftpboot/kernel" and that
the LTSP server is the DNS server (which it wrong). Very confusing to me.
In any case, the terminal has always recieved the .110 IP, so I am not
worried about that at the moment, and the line in /etc/hosts on Sheridan
(.27) should work AFAIK.
