Hi dear all,
I run Debian under laptop and for the last few weeks I have the following problem.
I'm in a Windows LAN and when I set my network settings to use DHCP every 10-15 the DNS was refreshed and lost internet so I had manualy to set DNS in network-admin (gnome-system-tools). Then I set a static IP and for 10 days I hado no problem. Today however even with static IP the DNS i put in network-admin simply disapears in 10-15 min and it is replased by an old DNS which I used in another LAN. So I constantly loose internet connection and had to manually set DNS which would not be so bad if the DNS stays as I specified it.

I read quite a lot of using bind9, dnsmasq, but so far I can not solve the problem.

Regards
Ivo
