Bug 354

It has been reported that the dhcpd.conf file created by ltspcfg contains a
nested subnet section.  It is commented out, so it doesn't cause a big problem,
but the comments indicate that you can un-comment that section to create a pool
of IP addresses.  It should be moved out of the enlosing section.

Here is the email sent by Jose Manuel Gomez:

Hello Jim

I have found something that may be an error on the dhcpd.conf file 
generated by ltspcfg.

This config includes this code:

subnet 172.27.0.0 netmask 255.255.0.0 {
    use-host-decl-names      on;
    option log-servers       172.27.6.152;


##
## If you want to use static IP address for your workstations, then un-comment
## the following section and modify to suit your network.
## Then, duplicate this section for each workstation that needs a static
## IP address.
##
##    host ws001 {                                       <----- Fix this
hostname
##        hardware ethernet    00:11:22:33:44:55;           <-- Fix this MAC
addr
##        fixed-address        192.168.0.1;                 <-- Fix this IP
addr
##        filename             "/lts/vmlinuz-2.4.21-ltsp-1";
##    }

##
## If you want to use a dynamic pool of addresses, then un-comment the
following
## lines and modify to match your network.
##
##    subnet  192.168.0.0 netmask 255.255.255.0 {
##        range dynamic-bootp 192.168.0.1 192.168.0.253;
##    }
##


}

As you can see, subnet section is repeated. The error says 'subnet section not
allowed' or something like that.

I now have this:

subnet 172.27.0.0 netmask 255.255.0.0 {

    use-host-decl-names      on;
    option log-servers       172.27.6.152;

#     }
