Hi,
OS : debian etch
DHCP : dhcp3-server
i deliver ip adress by range, the problem is that the server gives 2
addresses for the same wokstation
Here's an example of dialogue between the station and the server :
DHCPDISCOVER from 00:0e:a6:a7:3f:a4 via eth0
DHCPOFFER on 192.168.250.229 to 00:0e:a6:a7:3f:a4 via eth0
DHCPREQUEST for 192.168.250.229 (192.168.250.1) from 00:0e:a6:a7:3f:a4
via eth0
DHCPACK on 192.168.250.229 to 00:0e:a6:a7:3f:a4 via eth0
DHCPREQUEST for 192.168.250.142 from 00:0e:a6:a7:3f:a4 via eth0
DHCPACK on 192.168.250.142 to 00:0e:a6:a7:3f:a4 (S-105-11) via eth0
DHCPREQUEST for 192.168.250.142 from 00:0e:a6:a7:3f:a4 (S-105-11) via eth0
DHCPACK on 192.168.250.142 to 00:0e:a6:a7:3f:a4 (S-105-11) via eth0
at first the server gives 192.168.250.229, but then the station claims
192.168.250.142
=> 2 addresses are hold on server side => i use double of addresses.
i put
deny duplicates;
default-lease-time 600; (instead of 43200 at the begining)
max-lease-time 7200;
=> i have less stations with 2 addresses
Does someone has a solution ?
Notice : all the stations have boot pxe on
