no free leases

Hi all,

i see in your syslog that some NIC ask an IP frequently and the dhcpd 
give one different each time, so the IP range it's rapidly empty (no 
free leases). I don't know if it's normal but may be one solution it's 
to assign a short "lease-time" to the IP address with :

default-lease-time 600;   (an IP for 10 minutes)
max-lease-time 7200;

see this page :

another solution very stable for my computers (less than ten) it's to 
assign fix address with :

    host PC_name1 {
      hardware ethernet xx:xx:xx:xx:xx:xx;
      fixed-address 192.168.0.X;
    host PC_name2 {
      hardware ethernet xx:xx:xx:xx:xx:yy;
      fixed-address 192.168.0.Y;

All this parameters are in the /etc/ltsp/dhcpd.conf

I hope this can help you

bests regards
