How to get the DNS server address which are specific to each ppp session. For example, I have two ppp sessions each one connected different service provider, how do I find out the DNS server IP address which are assigned by each service provider? In general, the /etc/ppp/resolv.conf file will be overwritten with the new DNS IP address whenever a new ppp session is established. Is there any way how we can maintain separate files for DNS servers for each service provider?
