Duplicated leases, same IP and same MAC

Hi Arun,
Thanks for you reply!
Right now i m not able to do those operations but..
I don't know if i got your thought but in case of problems with RAS (that raise the creation of duplication of leases) why did the duplicated lease disappeared?
if the end time is on both leases are:
ends 2 2011/09/20 22:57:21;
and after a while (1h after creation, and a lease time of 8h) 1 of the 2 got away..
starts 2 2011/09/20 14:57:21; --> lease creation
around 16h -->1 of the leases is gone (i m not complaining about this :) )
ends 2 2011/09/20 22:57:21; --> lease end time
Do you have any thought for this behavior?
Thanks,
Carlos

Carlos,
Could you check Windows machine with RAS (Remote Access Service)
enabled or not… if it is enabled, disable it from DHCP server or stop the
service and renew the IP..
Thanks,

Hi
all,
Today i was looking into the lease file and found something that i think that
should not happen.
In the lease file i found 2 leases with the same IP and MAC, to one par IP MAC
there should exist just one lease right?
lease 10.43.11.92 {
starts 2 2011/09/20 14:57:21;
ends 2 2011/09/20 22:57:21;
tstp 3 2011/09/21 02:57:21;
tsfp 2 2011/09/20 22:57:22;
cltt 2 2011/09/20 14:57:21;
binding state active;
next binding state expired;
hardware ethernet 00:40:ca:a4:3f:be;
set ddns-txt = "0097558cd8aa1f47ff41f956ea212c89b8";
set ddns-fwd-name = "00:40:ca:a4:3f:be.teste.t";
client-hostname "T5413";
}
lease 10.43.11.92 {
starts 2 2011/09/20 14:57:21;
ends 2 2011/09/20 22:57:21;
tstp 3 2011/09/21 02:57:21;
tsfp 3 2011/09/21 02:57:21;
atsfp 3 2011/09/21 02:57:21;
cltt 2 2011/09/20 14:57:21;
binding state active;
next binding state expired;
hardware ethernet 00:40:ca:a4:3f:be;
set ddns-txt = "0097558cd8aa1f47ff41f956ea212c89b8";
set ddns-fwd-name = "00:40:ca:a4:3f:be.teste.t";
client-hostname "T5413";
}
After some minutes the file only had one.
i tested with omshell and i saw the error:
can't open object: more than one object matches key
Witch means that in memory structure in DHCPd there are more 2 leases
The version that i m running is 3.1.3, is this the normal behavior? or
its a bug? it's corrected in newer versions?
Thanks,
Carlos Abrantes
