I don't see:
> HOST bkeefe.dkc.jhu.edu { fixed-address 128.220.212.85;
in the file you sent, which makes it hard to see why this might cause a
problem :)
My guess would be that you are putting it inside this block:
subnet 128.220.212.64 netmask 255.255.255.192 {
option routers 128.220.212.65;
option time-servers ntp1.jhu.edu;
option domain-name-servers 120.220.8.20,128.220.8.21;
authoritative;
ddns-updates off;
}
If that is the case, it might be that since you do specify a "range"
option listing the available DHCP IP addresses for the subnet, you see
the "no free leases" message when that block is matched.
In my dhcpd.conf files, I have fixed addresses outside of
"shared-network" blocks and in a separate "group" block. Something like
this:
default-lease-time 21600;
max-lease-time 21600;
ddns-update-style none;
option subnet-mask 255.255.254.0;
option broadcast-address 146.27.79.255;
option routers 146.27.78.1;
option domain-name-servers 146.27.66.35;
option domain-name "chvpk.chevrontexaco.net";
option root-path "146.27.79.181:/opt/ltsp/i386";
shared-network WORKSTATIONS {
subnet 146.27.78.0 netmask 255.255.254.0 {
range 146.27.79.77 146.27.79.80;
}
}
shared-network WORKSTATIONS-PRIVATE {
subnet 10.0.78.0 netmask 255.255.254.0 {
range 10.0.79.79 10.0.79.80;
}
}
group {
use-host-decl-names on;
option log-servers 146.27.79.181;
filename "/lts/2.6.20.9-ltsp-1/pxelinux.0";
#filename "/lts/2.4.26-ltsp-3/pxelinux.0";
host cpafiszw {
hardware ethernet 90:12:02:50:4E:89;
fixed-address 146.27.79.81;
}
host cpafiszx {
hardware ethernet 90:12:02:50:1F:EF;
fixed-address 146.27.79.82;
}
host cpafiszy {
hardware ethernet 90:12:02:50:4E:96;
fixed-address 146.27.79.83;
}
host cpafiszz {
hardware ethernet 90:12:02:50:4E:9D;
fixed-address 146.27.79.84;
}
}
Hope this helps.
