Duplicated leases, same IP and same MAC

[arun.sasi1 at wipro.com]

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,

-Arun

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
