Hi Serg,

In the /etc/resolve.conf i see OLD RECORDS for DNS Server !!

please define “OLD RECORDS”…

Judging from the subject line, you’ve configured your machine as a dhcp client. Have you checked what the DHCP server is handing out? Did you receive a DHCP reply at all? What’s in the logs, what are the time stamps of the corresponding files (especially the .info file from the DCHP client, /etc/resolv.conf) and have you probably deactivated automatic modification of /etc/resolv.conf?

structural approach:

  • does your machine actually issue a DHCP request on boot?
  • does your machine receive a DHCP reply?
  • does the DHCP reply contain the proper values?
  • does the DHCP client try to update resolv.conf?
  • is resolv.conf updated at all (but probably with wrongs values)?

Regards,
Jens
